[PMID: 38775471 DOI: 10.1002/ps.8181] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/03/2024] [Revised: 04/18/2024] [Accepted: 05/06/2024] [Indexed: 08/10/2024]
Abstract
BACKGROUND Tetranychus cinnabarinus is one of the most common polyphagous arthropod herbivores, and is primarily controlled by the application of acaricides. The heavy use of acaricides has led to high levels of resistance to acaricides such as cyflumetofen, which poses a threat to global resistance management programs. Cyflumetofen resistance is caused by an increase in metabolic detoxification; however, the role of uridine diphosphate (UDP)-glycosyltransferase (UGT) genes in cyflumetofen resistance remains to be determined. RESULTS Synergist 5-nitrouracil (5-Nul) significantly enhanced cyflumetofen toxicity in T. cinnabarinus, which indicated that UGTs are involved in the development of cyflumetofen resistance. Transcriptomic analysis and quantitative (q)PCR assays demonstrated that the UGT genes, especially UGT201H1, were highly expressed in the YN-CyR strain, compared to those of the YN-S strain. The RNA interference (RNAi)-mediated knockdown of UGT201H1 expression diminished the levels of cyflumetofen resistance in YN-CyR mites. The findings additionally revealed that the recombinant UGT201H1 protein plays a role in metabolizing cyflumetofen. Our results also suggested that the aromatic hydrocarbon receptor (AhR) probably regulates the overexpression of the UGT201H1 detoxification gene. CONCLUSION UGT201H1 is involved in cyflumetofen resistance, and AhR may regulates the overexpression of UGT201H1. These findings provide deeper insights into the molecular mechanisms underlying UGT-mediated metabolic resistance to chemical insecticides. © 2024 Society of Chemical Industry.

Abstract
To explore natural product-based pesticide candidates, a series of indole derivatives containing the isoxazoline skeleton at the N-1 position were synthesized by 1,3-dipolar [2 + 3] cycloaddition reaction. Their structures were characterized by melting points (mp), infrared (IR) spectra, proton nuclear magnetic resonance spectra (1H NMR), carbon-13 nuclear magnetic resonance spectra (13C NMR), and high resolution mass spectrometry (HRMS). The single-crystal structures of five compounds were presented. Against Tetranychus cinnabarinus Boisduval, compound 3b showed greater than 3.8-fold acaricidal activity of indole and good control effects under glasshouse conditions. Against Aphis citricola Van der Goot, compounds 3b and 3q exhibited 48.3- and 36.8-fold aphicidal activity of indole and 6-methylindole, respectively. Particularly, compound 3b showed good bioactivities against T. cinnabarinus and A. citricola. Against Eriosoma lanigerum Hausmann, compound 3h and 3i showed 2.1 and 1.9 times higher aphicidal activity compared to indole. Furthermore, the construction of the epidermal cuticle layer of 3b-treated carmine spider mites was distinctly damaged, which ultimately led to their death.

Cross-resistance, inheritance and biochemical mechanism of abamectin resistance in a field-derived strain of the citrus red mite, Panonychus citri (Acari: Tetranychidae). PEST MANAGEMENT SCIENCE 2024; 80:1258-1265. [PMID: 37889506 DOI: 10.1002/ps.7855] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Revised: 10/20/2023] [Accepted: 10/27/2023] [Indexed: 10/28/2023]
Abstract
BACKGROUND The citrus red mite, Panonychus citri (McGregor), a global pest of citrus, has developed different levels of resistance to various acaricides in the field. Abamectin is one of the most important insecticides/acaricides worldwide, targetting a wide number of insect and mite pests. The evolution of abamectin resistance in P. citri is threatening the sustainable use of abamectin for mite control. RESULTS The abamectin resistant strain (NN-Aba), derived from a field strain NN by consistent selection with abamectin, showed 4279-fold resistance to abamectin compared to a relatively susceptible strain (SS) of P. citri. Cross-resistance of NN-Aba was observed between abamectin and emamectin benzoate, pyridaben, fenpropathrin and cyflumetofen. Inheritance analyses indicated that abamectin resistance in the NN-Aba strain was autosomal, incompletely recessive and polygenic. The synergy experiment showed that abamectin toxicity was synergized by piperonyl butoxide (PBO), diethyl maleate (DEM) and tributyl phosphorotrithiotate (TPP) in the NN-Aba strain, and synergy ratios were 2.72-, 2.48- and 2.13-fold, respectively. The glutathione-S-transferases activity in the NN-Aba strain were significantly increased by 2.08-fold compared with the SS strain. CONCLUSION The abamectin resistance was autosomal, incompletely recessive and polygenic in P. citri. The NN-Aba strain showed cross-resistance to various acaricides with different modes of action. Metabolic detoxification mechanism participated in abamectin resistance in NN-Aba strain. These findings provide useful information for resistance management of P. citri in the field. © 2023 Society of Chemical Industry.

[PMID: 37959851 PMCID: PMC10648920 DOI: 10.3390/molecules28217432] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2023] [Revised: 10/25/2023] [Accepted: 11/03/2023] [Indexed: 11/15/2023] Open
Abstract
Cyetpyrafen is a compound that lacks inherent uptake and systemic translocation activity. If mites do not come into direct contact with the pesticide solution on leaves, the efficacy cannot be achieved. Controlling the particle size can potentially play a crucial role in the manifestation of efficacy. In this study, high-throughput formulation technology was used to systematically screen a large number of adjuvants to obtain cyetpyrafen formulations. The particle size of the active ingredient in the formulation was measured. By examining the dynamic light scattering and contact angle, we simulated the actual process of the efficacy transmission of cyetpyrafen formulations against Tetranychus cinnabarinus. Our results showed that the activity of cyetpyrafen increases as the particle size decreases, suggesting that reducing the particle size can enhance the coverage and deposition on crop leaves, and further improve the dispersion efficiency and enhance spreading capabilities. Furthermore, controlling the particle size at 160 nm resulted in an LC50 value of 0.2026, which is approximately double than that of the commercial product. As a novel pesticide for mites, our study presents the most effective cyetpyrafen formulation in practice. Our findings provide valuable insights into controlling other mite species that pose a threat to agricultural products.

The dynamic changes of genes revealed that persistently overexpressed genes drive the evolution of cyflumetofen resistance in Tetranychus cinnabarinus. INSECT SCIENCE 2022. [PMID: 36380571 DOI: 10.1111/1744-7917.13151] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/05/2022] [Revised: 11/02/2022] [Accepted: 11/07/2022] [Indexed: 06/16/2023]
Abstract
Changes in gene expression are associated with the evolution of pesticide resistance in arthropods. In this study, transcriptome sequencing was performed in 3 different resistance levels (low, L; medium, M; and high, H) of cyflumetofen-resistant strain (YN-CyR). A total of 1 685 genes, including 97 detoxification enzyme genes, were upregulated in all 3 stages, of which 192 genes, including 11 detoxification enzyme genes, showed a continuous increase in expression level with resistance development (L to H). RNA interference experiments showed that overexpression of 7 genes (CYP392A1, TcGSTd05, CCE06, CYP389A1, TcGSTz01, CCE59, and CYP389C2) is involved in the development of cyflumetofen resistance in Tetranychus cinnabarinus. The recombinant CYP392A1 can effectively metabolize cyflumetofen, while CCE06 can bind and sequester cyflumetofen in vitro. We compared 2 methods for rapid screening of resistance molecular markers, including short-term induction and 1-time high-dose selection. Two detoxification enzyme genes were upregulated in the field susceptible strain (YN-S) by induction with 20% lethal concentration (LC20 ) of cyflumetofen. However, 16 detoxification enzyme genes were upregulated by 1-time selection with LC80 of cyflumetofen. Interestingly, the 16 genes were overexpressed in all 3 resistance stages. These results indicated that 1 685 genes that were upregulated at the L stage constituted the basis of cyflumetofen resistance, of which 192 genes in which upregulation continued to increase were the main driving force for the development of resistance. Moreover, the 1-time high-dose selection is an efficient way to rapidly obtain the resistance-related genes that can aid in the development of resistance markers and resistance management in mites.

Abstract
BACKGROUND Laodelphax striatellus (Fallén) (Hemiptera: Delphacidae) is one of the most important insect pests of rice, and it has been able to develop strong resistance to many insecticides. Triflumezopyrim, a new type of mesoionic insecticide developed by Corteva Agriscience, showed high biological activity in controlling piercing-sucking insect pests such as planthopper and leafhopper. RESULTS In this study, we continuously selected a susceptible laboratory stain (Unsel) of L. striatellus for 16 generations by exposing it to triflumezopyrim in the laboratory. A 45.1-fold triflumezopyrim-resistant strain (Tri-sel) was established, in which cross-resistance to nitenpyram and acetamiprid was not detected. The realized heritability (h2 ) of the Tri-sel strain was estimated at 0.13. The mortalities of the testing F1 (the offspring of a cross between Unsel and Tri-sel strains) suggested that the resistance of L. striatellus to triflumezopyrim was autosomal and incompletely dominant, as well as a polygenic inheritance. In addition, the results of synergist experiment showed that P450s potentially contributed to the triflumezopyrim resistance. The activities of detoxification enzymes in the Unsel and Tri-sel strains indicated that the activity of P450s in the Tri-sel strain was significantly increased, consistent with the results of synergist experiments. Furthermore, 12 P450 genes demonstrated significant up-regulation. CONCLUSIONS L. striatellus has a certain risk of resistance to triflumezopyrim after continuous selection. Triflumezopyrim resistance did not result in cross-resistance to neonicotinoid insecticides. The up-regulation of multiple P450 genes may mediate triflumezopyrim resistance in L. striatellus. © 2022 Society of Chemical Industry.

PESTICIDE BIOCHEMISTRY AND PHYSIOLOGY 2022; 183:105062.

Abstract
Cyetpyrafen belonging to mitochondrial electron transport inhibitors of complex II (METI II) has been widely applied to manage pest mites in China. To investigate the adaption of Tetranychus urticae in the evolution of cyetpyrafen resistance, a study of cross resistance, mode of inheritance and fitness comparison of resistance using indoor cyetpyrafen resistant strain (resistance ratio, RR > 2, 000-fold) was executed. Cyet-R showed serious cross resistance to cyenopyrafen (>2500-fold) and cyflumetofen (~190-fold). The number of resistant genes was evaluated via chi-square (χ2) test and the concentration-response curve regarding goodness-of-fit between observed and the expected mortality. The LC50s of F1RS (Cyet-R♀ × Tu-YN♂) and F1SR (Tu-YN♀ × Cyet-R♂) were 3126.30 mg/L and 2743.97 mg/L, respectively, without significance, suggesting autosomal inheritance. The degree of dominance (D) values of F1RS and F1SR ranged between 0 and 1, revealing an incompletely dominant inheritance in the tested population of Tetranychus urticae. Plots of concentration-response data for the orthogonal backcross and reverse backcross progenies showed a significant deviation from the expected lines, pointing out a polygenic inheritance. Besides, lifetable analysis showed a fitness advantage of Cyet-R with a significantly decreased adult preadult period and significantly increased total fecundity. This study suggested that cyetpyrafen resistance against T. urticae was inherited as autosomal, incompletely dominant and multigenetic and characterized with serious cross resistance and fitness advantage. Therefore, rational application and preventive strategy should be considered to sustain the efficacy of cyetpyrafen against T. urticae.

Abstract
As a newly recognized type of noncoding RNA, circular RNA can mediate a variety of physiological changes in mammals by regulating the post-transcriptional expression level of genes. However, the function of circRNA in the evolution of pesticide resistance in arthropods is still unknown. In this study, 2546 circRNAs were identified in Tetranychus cinnabarinus by transcriptome sequencing. The differentially expressed gene analysis indicated that 44 circRNAs were overexpressed in a cyflumetofen-resistant strain, of which a circRNA (named circ1-3p) was found to contain the response elements of miR-1-3p, an miRNA that is involved in cyflumetofen resistance by targeting TcGSTm04. The circular structure of circ1-3p was further determined using a divergent primer. The results of different molecular assays in vitro and in vivo showed that circ1-3p can compete with TcGSTm04 in miR-1-3p binding. The colocalization of circ1-3p and miR-1-3p was found using fluorescence in situ hybridization, suggesting that circ1-3p can directly sponge miR-1-3p in T. cinnabarinus. In addition, silencing the expression of circ1-3p resulted in the upregulation of miR-1-3p and the downregulation of TcGSTm04 as well as a significant increase in the sensitivity of T. cinnabarinus to cyflumetofen. All these pieces of evidence indicates that overexpressed circ1-3p promotes the expression of TcGSTm04 through sponging miR-1-3p, thereby involving in the evolution of cyflumetofen resistance in T. cinnabarinus.

Zhou H, Liu J, Wan F, Guo F, Ning Y, Liu S, Ding W. Insight into the mechanism of action of scoparone inhibiting egg development of Tetranychus cinnabarinus Boisduval. Comp Biochem Physiol C Toxicol Pharmacol 2021; 246:109055. [PMID: 33894369 DOI: 10.1016/j.cbpc.2021.109055] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2021] [Revised: 03/17/2021] [Accepted: 04/07/2021] [Indexed: 01/03/2023]
Abstract
Investigating the mechanisms of action of natural bioactive products against pests is a vital strategy to develop novel promising biopesticides. Scoparone, isolated from Artemisia capillaris, exhibited potent oviposition inhibition activity against Tetranychus cinnabarinus (a crop-threatening mite pests with strong fecundity). To explore the underlying mechanism, the vitellogenin (Vg) protein content, and Vg gene expression of mites from three consecutive generations of G0 individuals exposed to scoparone were determined, revealing marked inhibition. This study is the first to explore the egg development defect behaviour of mite pests induced by scoparone. The egg-laying inhibition of mites by scoparone was significantly increased by 47.43% compared with that of the control when TcVg was silenced by RNA interference (RNAi), suggesting that egg-development inhibition of female T. cinnabarinus by scoparone was mediated by low Vg gene expression. Furthermore, scoparone bound to the Vg protein in vitro, and its Kd value was 218.9 μM, implying its potential function in inhibiting the egg development of mites by directly targeting the Vg protein. This study will lay the foundation for the future applications of scoparone as an agrochemical for controlling the strong egg-laying capacity mite pests in agriculture.

ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2021; 217:112234. [PMID: 33864981 DOI: 10.1016/j.ecoenv.2021.112234] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/28/2020] [Revised: 04/05/2021] [Accepted: 04/05/2021] [Indexed: 06/12/2023]
Abstract
The toxicity tests of nineteen commonly used pesticides were carried out to compare the sensitivity differences between predatory mite Neoseiulus cucumeris and its prey Tetranychus cinnabarinus by a "leaf spray method" in laboratory microcosms. For two avermectins, emamectin benzoate and abamectin, exhibited high bioactivity against T. cinnabarinusf with LR50 values of 0.04 and 0.05 g a.i./ha, respectively, but these two insecticides showed the opposite toxic effects to N. cucumeris. These two agents showed strong selectivity for the two test species with Selective Toxicity Rate (STR) values of 950 and 620, respectively. However, for five neonicotinoids, the LR50s of dinotefuran, thiamethoxam, imidacloprid, and acetamiprid were all greater than the recommended rates in the field except for clothianidin, and they showed no obvious toxicity difference to the two species with STR values ranging from 0.58 to 2.00. For two organophosphates, malathion is more toxic to N. cucumeris than T. cinnabarinus, however, dimethoate showed a higher toxic effect on T. cinnabarinus. In addition, the toxicity of four pyrethroids, bifenthrin, deltamethrin, cyhalothrin and gamma-cyhalothrin to N. cucumeris was higher than that of T. cinnabarinus, except for alpha-cypermethrin. For five acaricides, spirodiclofen, spirotetramat and pyridaben had no obvious selectivity to the two organisms, while diafenthiuron and chlorfenapyr were found to be highly toxic to T. cinnabarinus than N. cucumeris with STR values of 14.2 and 68.5, respectively. Thus, some pesticides above-mentioned like emamectin benzoate, abamectin, diafenthiuron and chlorfenapyr exhibited potential to be used in the management programs of T. cinnabarinus, especially in organically based production systems where there are fewer chemical control measures available, which need to combine with natural enemies to achieve the best control effect.

Abstract
BACKGROUND Dusky cotton bug (DCB), Oxycarenus hyalinipennis (Costa) (Hemiptera: Lygaeidae), is a key insect pest of cotton. It causes huge losses to cotton and many other economically important crops. Sulfoxaflor is a newly introduced systemic insecticide that is effective against many sap-feeding insect pests such as aphids, whiteflies and true bugs. The present study was designed to characterize the inheritance of sulfoxaflor resistance in DCB. Moreover, the role of synergists in reducing sulfoxaflor resistance in DCB was also assessed. RESULTS A field population of DCB has developed 1132.0-fold resistance to sulfoxaflor after 11 selected generations in the laboratory. Nonsignificant difference of reciprocal crosses was observed depending on the LC50 (median lethal concentration) values (95% confidence intervals overlapped), suggesting an autosomal mode of sulfoxaflor resistance inheritance. The degree of dominance of 0.7 for F1 (Sulfo-Sel Pop ♀ × Lab-Pop♂) and 0.6 for F1 '(Sulfo-Sel Pop ♂ × Lab-Pop♀), respectively, suggested that sulfoxaflor resistance was incompletely dominant. According to the monogenic model, the number of genes involved to induce sulfoxaflor resistance revealed that sulfoxaflor resistance was polygenic in nature. The realized heritability (h2 ) value for sulfoxaflor resistance was 0.2. The synergists experiment indicated that esterases were involved in the sulfoxaflor resistance mechanism in DCB. CONCLUSIONS The current results indicate that there is autosomal, incompletely dominant and polygenic inheritance of sulfoxaflor resistance in DCB. Our results would be helpful in delaying sulfoxaflor resistance against DCB in the field. © 2021 Society of Chemical Industry.

PESTICIDE BIOCHEMISTRY AND PHYSIOLOGY 2021; 173:104799. [PMID: 33771268 DOI: 10.1016/j.pestbp.2021.104799] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/06/2020] [Revised: 12/17/2020] [Accepted: 02/01/2021] [Indexed: 06/12/2023]
Abstract
Metabolic resistance is one of the main causes of acaricide resistance. Many previous studies focused on the function of specific genes in insecticides/acaricides resistance. However, during the development of resistance, the overall dynamic of expression levels of detoxification enzyme genes in mites is still unclear. Tetranychus cinnabarinus, a major agricultural pest, which is notorious for developing resistance to acaricides rapidly. In this study, a field susceptible strain (YS) was continuously selected for 16, 25 and 32 generations, and developed to low resistance (7.83-fold, L), medium resistance (17.23-fold, M) and high resistance (86.05-fold, H), respectively. Transcriptome sequencing was performed in YS, L, M and H strains. Overall, compared with YS strain, the number of differential expression genes increased slightly with the development of cyflumetofen-resistance. As for detoxification genes, the median of fold change of up-regulated P450、CCE and GST genes was higher than those of all up-regulated genes in three resistance level, but only the number and the median of fold change of up-regulated P450 genes was increased slightly with the development of resistance. In addition, synergism experiments also proved that P450 and GST genes were the major contributors to the metabolic resistance of cyflumetofen of T. cinnabarinus. These results showed that the resistance of T. cinnabarinus to cyflumetofen was related to many resistant genes, among which P450 genes could play crucial roles in cyflumefen resistance.

Abstract
BACKGROUND Tetranychus urticae is a notorious crop pest with a worldwide distribution that has developed resistance to a wide range of acaricides. Here, we investigated the resistance levels of a T. urticae population collected from an ornamental greenhouse in Peloponnese, Greece, and analyzed its resistance mechanisms at the molecular level. RESULTS Toxicological assays showed resistance against compounds with different modes of action, with resistance ratios of: 89-fold for abamectin; > 1000-fold for clofentezine; > 5000-fold for etoxazole; 27-fold for fenpyroximate and pyridaben; 20- and 36-fold for spirodiclofen and spirotetramat, respectively; and 116- and > 500-fold for cyenopyrafen and cyflumetofen, respectively. Bioassays with synergists indicated the involvement of detoxification enzymes in resistance to abamectin, but not to cyflumetofen and spirodiclofen. RNA sequencing (RNA-seq) analysis showed significant over-expression of several genes encoding detoxification enzymes such as cytochrome P450 monooxygenases and UDP-glycosyltransferases, which have been previously associated with acaricide resistance. Known target-site resistance mutations were identified in acetyl-choline esterase, chitin synthase 1 and NDUFS7/psst, but putative novel resistance mutations were also discovered in targets such as glutamate-gated chloride channel subunit 3. Interestingly, target-site resistance mutations against pyrethroids or bifenazate were not identified, possibly indicating a recent reduced selection pressure in Greece, as well as a possible opportunity to rotate these chemistries. CONCLUSION We identified and characterized a striking case of multiple acaricide resistance in a field population of T. urticae. Exceptionally strong resistance phenotypes, with accumulation of multiple resistance mutations and over-expression of P450s and other detoxification genes in the same field population are reported.

Abstract
Selenium is a trace element necessary for living organisms. It exists mainly in the form of selenite in nature. In plants, selenium can enhance defenses against pests. In this study, transcriptome sequencing technology was used to analyze the response mechanism of Tetranychus cinnabarinus to plant-mediated selenium treatment. We tested four sodium selenite treatments (5, 20, 50, and 200 μM) that were the same for short (2 d) and long (30 d) treatment durations. The results showed that the number of differentially expressed genes (DEGs) in the short-term treatment was greater than in the long-term treatment. This indicated that the gene expression of spider mites gradually stabilized during the selenium treatment. Regardless of the long-term and short-term conditions, spider mites had the largest response to the 20 μM sodium selenite treatment. The functional annotation classification of DEGs showed no significant difference under different concentrations and treatment durations. A total of 25 genes were differentially expressed in all eight treatments, including four down-regulated cytochrome P450 genes and one up-regulated chitinase gene. We speculate that selenium may have the potential to enhance the activity of chemical acaricides. Transcriptome sequencing of sodium selenite treatment at different concentrations and different times revealed the response mechanism of spider mites under plant-mediated selenium treatment. At the same time, it also provides new clues for the development of methods for preventing and controlling spider mites with selenium.

Abstract
The carmine spider mite, Tetranychus cinnabarinus (Boisduval), is a polyphagous agricultural pest with an extensive host plant range. Scopoletin is a promising acaricidal compound whose acaricidal mechanism may occur by disrupting intracellular Ca2+ homeostasis and calcium signaling pathways. However, the underlying mechanism of scopoletin for specific target locations of T. cinnabarinus remains unclear. In this study, a full-length cDNA of the L-type voltage-gated calcium channel (TcLTCC) subunit gene from T. cinnabarinus was cloned and characterized. The expression pattern of the TcLTCC gene in all developmental stages of T. cinnabarinus was analyzed. The gene was highly expressed in larval and nymphal stages and was significantly upregulated after treatment with scopoletin. Knocking down the TcLTCC transcript reduced the sensitivity of T. cinnabarinus to scopoletin. Homology modeling and molecular docking were also conducted. The interaction between scopoletin and TcLTCC showed that scopoletin inserted into the cavity bound to the site of the TcLTCC protein by the driving force of hydrogen bonding. This study provides insights into the mechanism by which scopoletin interacts with TcLTCC. Results can improve the understanding of the toxicity of scopoletin to T. cinnabarinus and provide valuable information for the design of new LTCC inhibitors.

Abstract
Differential expression of metabolic detoxification enzymes is an important mechanism involved in pesticide/acaricide resistance of mite pests. The competing endogenous RNA hypothesis offers a new opportunity to investigate post-transcriptional regulation of those genes. In this study, 4454 long non-coding RNAs were identified in the carmine spider mite Tetranychus cinnabarinus by transcriptome sequencing. Software-based predictions indicated that a long intergenic non-coding RNA, (lincRNA)_Tc13743.2 and a detoxification enzyme gene, TcGSTm02, both contained a microRNA (miR-133-5p) response element. Over-expression of lincRNA_Tc13743.2 and TcGSTm02 were detected in a cyflumetofen-resistant T. cinnabarinus strain (CyR), whereas down-regulation of miR-133-5p was observed in this strain. Conversely, up-regulation of miR-133-5p could inhibit TcGSTm02 expression levels, and both lincRNA_Tc13743.2 and TcGSTm02 were significantly enriched in miR-133-5p biotin-avidin pull-down assays. RNA-binding protein immunoprecipitation assay showed that lincRNA_Tc13743.2 and TcGSTm02 bound to a silencing complex containing miR-133-5p. Moreover, a luciferase reporter assay based on a human cell line revealed that over-expression of lincRNA_Tc13743.2 could significantly reduce the inhibition exerted by miR-133-5p through the TcGSTm02 3'UTR. In addition, co-localization of lincRNA_Tc13743.2 and miR-133-5p was detected using fluorescence in situ hybridization, suggesting that lincRNA_Tc13743.2 interacts directly with miR-133-5p in spider mites. More importantly, silencing the expression of lincRNA_Tc13743.2 significantly reduced the expression levels of TcGSTm02 and increased the sensitivity of spider mites to cyflumetofen. Our data show that lincRNA_Tc13743.2 up-regulates TcGSTm02 expression by competing for miR-133-5p binding, demonstrating that a lincRNA_Tc13743.2-miR-133-5p-TcGSTm02 pathway mediates cyflumetofen resistance in mites.

Pan D, Dou W, Yuan GR, Zhou QH, Wang JJ. Monitoring the Resistance of the Citrus Red Mite (Acari: Tetranychidae) to Four Acaricides in Different Citrus Orchards in China. JOURNAL OF ECONOMIC ENTOMOLOGY 2020; 113:918-923. [PMID: 31819971 DOI: 10.1093/jee/toz335] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/29/2019] [Indexed: 06/10/2023]
Abstract
The citrus red mite, Panonychus citri (McGregor), is an important spider mite pest in citrus producing areas. Owing to long-term acaricide exposure, resistance has evolved rapidly in recent years. To evaluate the extent of resistance, seven field mite populations sampled from various geographical locations in China during 2015-2018 were tested using the leaf-dip bioassay method to determine their susceptibilities to four acaricides. In comparison with the susceptible strain maintained in the laboratory, low or moderate levels of fenpropathrin resistance, while no resistance to abamectin or cyflumetofen, were found among populations sampled from Liangping, Wanzhou, Daying, and Anyue in Southwestern China during the test period. High levels (>1,000-fold, with LC50 values that were greater than the recommended concentration) of resistance to fenpropathrin had evolved in field populations from Southern China, including Guilin, Nanning, and Yuxi, when compared with that of the susceptible strain. Populations from Guilin and Nanning also evolved high resistance levels to abamectin (1,088-fold and 1,401-fold) and cyflumetofen (2,112-fold and 9,093-fold). All the populations sampled in 2018 showed a moderate or high resistance to bifenazate. Generally, field populations of citrus red mites from Southwestern China were more sensitive to the tested acaricides than those of Southern China. The data provide a foundation for developing acaricide resistance management strategies in these regions.

PESTICIDE BIOCHEMISTRY AND PHYSIOLOGY 2020; 163:31-38. [PMID: 31973868 DOI: 10.1016/j.pestbp.2019.10.001] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/27/2019] [Revised: 07/26/2019] [Accepted: 10/14/2019] [Indexed: 06/10/2023]
Abstract
Amidase is an important hydrolytic enzyme in detoxification metabolism. Amidase hydrolyzes a wide variety of nonpeptide carbon‑nitrogen bonds by attacking a cyano group or carbonyl carbon. However, little is known about the relationship between amidase and insecticides. In this study, the amidase activity was significantly higher in cyflumetofen-resistant strain (CyR) than in the susceptible strain (SS) of Tetranychus cinnabarinus, and diethyl-phosphoramidate (an amidase inhibitor) significantly decreased cyflumetofen resistance in T. cinnabarinus. More importantly, an amidase gene, TcAmidase01, was identified in T. cinnabarinus, and the TcAmidase01 overexpression was detected in both two cyflumetofen-resistant strains (CyR and YN-CyR), indicating that it is involved in cyflumetofen resistance in mites. A phylogenetic analysis showed that TcAmidase01 was clustered with deaminated glutathione amidases, which possess hydrolytic activity. The recombinant TcAmidase01 protein showed amidase activity toward succinamate, and the activity could be inhibited by cyflumetofen. High-performance liquid chromatography-mass spectrometry (HPLC-MS) analysis provided evidence that recombinant TcAmidase01 could decompose cyflumetofen by hydrolysis, and the potential metabolites (2-(4-(tert-butyl) phenyl)-2-cyanoacetate and 2-(trifluoromethyl) benzoic acid) were identified. These results show that TcAmidase01 contribute to cyflumetofen-resistance in T. cinnabarinus by hydrolyzing cyflumetofen, and this is the first study to suggest that amidase has a role in insecticides resistance in arthropods.

Abstract
BACKGROUND Acaricide resistance is a serious problem in spider mites. Cyflumetofen is a new complex II inhibitor, whereas pyridaben acts at complex I and has been used for decades. Although cross-resistance between cyflumetofen and pyridaben has been observed in Tetranychus cinnabarinus, the specific mechanisms at play have not yet been investigated. RESULTS Investigation into the cross-resistance mechanisms identified five P450s, among which CYP389C16 was evaluated as the most likely candidate conferring cross-resistance. Knockdown of CYP389C16 expression via RNA interference diminished the level of cross-resistance in the cyflumetofen-resistant strain. In addition, recombinant CYP389C16 (40 pmol) effectively metabolized 25.0 ± 0.7% of cyflumetofen, 39.7 ± 1.0% of pyridaben, and 69.3 ± 3.3% of AB-1 (active de-esterified metabolite of cyflumetofen) within 2 h. In addition, hydroxylation metabolite of AB-1 was identified by HPLC-MS/MS. CONCLUSIONS The study reveals that overexpressed CYP389C16 is involved in the cross-resistance between cyflumetofen and pyridaben in T. cinnabarinus. © 2019 Society of Chemical Industry.

Abstract
BACKGROUND Cotton mealybug Phenacoccus solenopsis is a pest of cotton, vegetables, ornamentals, and medicinal plants. In many parts of the world P. solenopsis has been managed by integration of cultural, mechanical, biological and chemical methods, but in Pakistan the use of insecticide sprays has resulted in the development of resistance to some insecticides. In this study indoxacarb resistance was investigated by selecting a P. solenopsis population under laboratory conditions for many generations. The cross-resistance potential of indoxacarb resistance with other chemistries and the realized heritability of indoxacarb resistance were also evaluated. RESULTS A field population of P. solenopsis selected with indoxacarb for 27 generations had a 25 623.17-fold resistance level. The highly indoxacarb resistant population showed very high cross-resistance to spinosad and very low cross-resistance to bifenthrin and chlorpyrifos. The mean estimated h2 of resistance to indoxacarb was only 0.04. The number of generations predicted for the development of ten-fold indoxacarb resistance at a constant h2 = 0.04 against selection intensities of 10% and 95% were 346 and 36 (slope = 3.18), 237 and 25 (slope = 2.18) and 128 and 13 (slope = 1.18). However, at a constant slope = 1.18 and selection intensities of 10% and 95%, the same increase in indoxacarb resistance occurred after 128 and 13 (h2 = 0.04), 103 and 11 (h2 = 0.05), and 86 and 9 (h2 = 0.06) generations. CONCLUSION This study revealed that P. solenopsis has a very high resistance to indoxacarb as a result of laboratory selection. Thus, resistance to this insecticide in the field may also occur. Indoxacarb resistance can be minimized by rotating it with bifenthrin and/or chlorpyrifos due to its very low cross-resistance to these insecticides and by avoiding its rotation with Spinosad, which has very high cross-resistance. © 2019 Society of Chemical Industry.

Abstract
BACKGROUND Sulfoxaflor has been considered as a new tool for Nilaparvata lugens control in the field. In this study, a laboratory-selected resistant strain and a susceptible strain were used to evaluate the inheritance and fitness costs of sulfoxaflor resistance in N. lugens. RESULTS The resistant strain (SFX-SEL) showed 123.63-fold resistance compared with the susceptible strain (SS). Progenies of reciprocal crosses (F1 RS and F1 SR) showed similar concentration-mortality responses (LC50 ) to sulfoxaflor and also exhibited a similar degree of dominance; -0.16 for F1 RS and -0.26 for F1 SR. Significant differences between the observed and expected mortalities of F2 individuals suggested that sulfoxaflor resistance is associated with multiple genes. The resistant strain had a relative fitness of 0.75 with substantially decreased female adult period, oviposition days, total fecundity, egg hatchability and female adult survival rate, and prolonged pre-adult period and total pre-oviposition period. CONCLUSION Sulfoxaflor resistance in N. lugens was inherited as autosomal, incompletely recessive and multigene. The development of resistance may have a significant fitness cost for the resistant population. Current research provides valuable information for researchers to establish management strategies to delay the development of sulfoxaflor resistance and control N. lugens sustainably in the field. © 2019 Society of Chemical Industry.

Abstract
BACKGROUND Cyflumetofen is an outstanding acaricide with a novel mode of action. Tetranychus cinnabarinus, an important agricultural pest, is notorious for developing resistance to most classes of acaricides rapidly and results in enormous loss for the economy. Our previous study had pointed out glutathione S-transferase (GSTs) significantly contributed to the cyflumetofen-resistance formation in T. cinnabarinus, but the more specific mechanism needed to be further investigated. RESULTS The unstable resistance was observed in cyflumetofen-resistant strain (CyR)under acaricide-free condition. The activity of GSTs increased along with the development of resistance. The expressions of 13 GST genes were detected in CyR and susceptible strain (SS), of which six genes were overexpressed in CyR and the TcGSTm02 was selected as the representative for functional study. The expression of TcGSTm02 changed along with the resistant level of CyR with the same trend. Recombinant protein of TcGSTm02 with high activity was successfully obtained by E. coli expression system, whose activity could be inhibited by cyflumetofen (IC50 = 0.23 mM). Recombinant TcGSTm02 could effectively decompose cyflumetofen, and catalyze GS- to conjugate with cyflumetofen. CONCLUSION All clues confirmed that GSTs strongly associated with cyflumetofen-resistance and a representative gene, TcGSTm02, showed function on contributing the evolution of cyflumetofen-resistance in T. cinnabarinus. © 2019 Society of Chemical Industry.

Abstract
BACKGROUND Increased expression or point mutations of carboxyl/cholinesterases (CCEs) have been involved in many cases of insecticide and acaricide resistance. However, it has been only rarely documented that downregulation of CCE genes is associated with resistance, although many insecticides and acaricides need hydrolytic activation in vivo. Previously, expression analysis of a laboratory-selected cyflumetofen-resistant strain of Tetranychus cinnabarinus indicated that resistance was associated with increased expression of a CCE gene of TcCCE04, but also the downregulation of two CCE genes, TcCCE12 and TcCCE23. RESULTS Synergism experiments revealed the importance of ester hydrolysis in cyflumetofen toxicity, because treatment with S,S,S-tributylphosphorotrithioate (DEF) caused strong inhibition of cyflumetofen hydrolysis, in both the susceptible and resistant strains. Moreover, silencing expression of TcCCE12 and TcCCE23 via RNAi further decreased the susceptibility of mites to cyflumetofen significantly, suggesting that downregulated CCE genes could be involved in cyflumetofen resistance. In addition, it was shown that recombinant TcCCE12 protein could hydrolyze cyflumetofen effectively. CONCLUSION Decreased esterase activity via downregulation of specific CCE genes most likely contributes to cyflumetofen resistance by decreased activation of cyflumetofen to its active metabolite. Mixtures of cyflumetofen and esterase-inhibition acaricides (e.g. organophosphates or carbamates) should be avoided in field applications. © 2019 Society of Chemical Industry.
