Contrasting roles of cytochrome P450s in amitraz and chlorfenapyr resistance in the crop pest Tetranychus urticae. INSECT BIOCHEMISTRY AND MOLECULAR BIOLOGY 2024; 164:104039. [PMID: 37992878 DOI: 10.1016/j.ibmb.2023.104039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Revised: 11/07/2023] [Accepted: 11/09/2023] [Indexed: 11/24/2023]
Abstract
The molecular mechanisms of amitraz and chlorfenapyr resistance remain only poorly understood for major agricultural pests and vectors of human diseases. This study focusses on a multi-resistant field strain of the crop pest Tetranychus urticae, which could be readily selected in the laboratory to high levels of amitraz and chlorfenapyr resistance. Toxicity experiments using tralopyril, the active toxophore of chlorfenapyr, suggested decreased activation as a likely mechanism underlying resistance. Starting from the same parental strain, transcriptome profiling revealed that a cluster of detoxifying genes was upregulated after amitraz selection, but unexpectedly downregulated after chlorfenapyr selection. Further functional validation associated the upregulation of CYP392A16 with amitraz metabolism and the downregulation of CYP392D8 with reduced activation of chlorfenapyr to tralopyril. Genetic mapping (QTL analysis by BSA) was conducted in an attempt to unravel the genetic mechanisms of expression variation and resistance. This revealed that chlorfenapyr resistance was associated with a single QTL, while 3 QTLs were uncovered for amitraz resistance. Together with the observed contrasting gene expression patterns, we argue that transcriptional regulators most likely underly the distinct expression profiles associated with resistance, but these await further functional validation.

Abstract
Malaria mosquitoes acoustically detect their mating partners within large swarms that form transiently at dusk. Indeed, male malaria mosquitoes preferably respond to female flight tones during swarm time. This phenomenon implies a sophisticated context- and time-dependent modulation of mosquito audition, the mechanisms of which are largely unknown. Using transcriptomics, we identify a complex network of candidate neuromodulators regulating mosquito hearing in the species Anopheles gambiae. Among them, octopamine stands out as an auditory modulator during swarm time. In-depth analysis of octopamine auditory function shows that it affects the mosquito ear on multiple levels: it modulates the tuning and stiffness of the flagellar sound receiver and controls the erection of antennal fibrillae. We show that two α- and β-adrenergic-like octopamine receptors drive octopamine's auditory roles and demonstrate that the octopaminergic auditory control system can be targeted by insecticides. Our findings highlight octopamine as key for mosquito hearing and mating partner detection and as a potential novel target for mosquito control.

Abstract
Neonicotinoid insecticides (NIs) are widely used worldwide, accounting for 25 % of the global insecticide market, and are easily transported into surrounding aquatic ecological environments after application. At present, >80 % of surface water is contaminated by NIs globally. Some transformation products (TPs) of NIs can exhibit greater toxicity to aquatic organism than their parent products. However, few studies have evaluated the toxicity and ecological risk of the TPs of NIs. In this study, we aimed to assess the toxicity and ecological risk of seven widely used NIs and their aerobic TPs to aquatic organisms using a prediction method. We found that partial aerobic TPs of NIs have greater toxicity to aquatic organisms than their parent products, and some of them could severely damage aquatic ecosystems. Meanwhile, acetamiprid, thiacloprid, and several other TPs of NIs with a chlorinated ring structure showed strong bioconcentration abilities, which could potentially harm aquatic organisms through the food chain. Moreover, the widespread use of NIs has certain aquatic ecological risks, which should be controlled and limited. This study comprehensively evaluated the ecological risk of seven widely used NIs and their aerobic TPs to aquatic organisms for the first time. Our results could provide an important reference for assessment of the aquatic environmental risk posed by NIs and pollution control.

Abstract
Culex pipiens complex is an important vector of epizootic and zoonotic pathogens, including West Nile virus. Chicago, Illinois and its suburbs have suffered high incidence of human West Nile virus infections in the past. This makes abatement programs in and around the Chicago area an essential service. The control of Cx. pipiens is often complicated by rapidly evolving resistance to pyrethroids, which are the most widely used chemical class in US mosquito abatement programs. The present study assessed Sumithrin® resistance in Cx. pipiens collected from five locations around Cook County, Illinois, neighboring the city limits of Chicago. According to CDC guidelines, samples from all five locations demonstrated some resistance to Sumithrin®. When assessed with Anvil®, a formulated product made of Sumithrin® synergized with piperonyl butoxide, susceptibility was rescued in mosquitoes from three out of the five locations, suggesting involvement of mixed-function oxidases and/or carboxylesterases in Sumithrin® resistance at these locations. Not all locations had susceptibility rescued by Anvil®, but these locations had relatively low knockdown resistance allele frequencies, suggesting that mechanisms other than knockdown resistance may be involved. Enzyme activities did not reveal any marked trends that could be related back to mortality in the bottle bioassays, which highlights the need for multiple types of assays to infer enzymatic involvement in resistance. Future directions in pyrethroid resistance management in Chicago area Cx. pipiens are discussed.

Short exposure to nitenpyram pesticide induces effects on reproduction, development and metabolic gene expression profiles in Drosophila melanogaster (Diptera: Drosophilidae). THE SCIENCE OF THE TOTAL ENVIRONMENT 2022; 804:150254.

Abstract
Although the toxicity of neonicotinoid insecticides has been demonstrated in several studies, the information on metabolism, behavior, and health risk remains limited and has raised concerns about its potential toxicity. Thus, in this study we assessed the effects of nitenpyram using different sublethal concentrations (one-third and one-tenth of the acute LC50 values) on various developmental and metabolic parameters from gene expression regulation in Drosophila melanogaster (model system used worldwide in ecotoxicological studies). As a result, nitenpyram sublethal concentrations prolonged the developmental time for both pupation and eclosion. Additionally, nitenpyram sublethal concentrations significantly decreased the lifespan, pupation rate, eclosion rate, and production of eggs of D. melanogaster. Moreover, the mRNA expression of genes relevant for development and metabolism was significantly elevated after exposure. Mixed function oxidase enzymes (Cyp12d1), (Cyp9f2), and (Cyp4ae1), hemocyte proliferation (RyR), and immune response (IM4) genes were upregulated, whereas lifespan (Atg7), male mating behavior (Ple), female fertility (Ddc), and lipid metabolism (Sxe2) genes were downregulated. These findings support a solid basis for further research to determine the hazardous effects of nitenpyram on health and the environment.

Abstract
Synergistic effects of octopamine receptor agonists (OR agonists) have attracted many scientists based on their potent effects on mosquitoes. Herein, we determined the toxicity of selected insect growth regulators (IGRs) on fourth instar larvae of Culex quinquefasciatus. We evaluated the synergistic action of OR agonists on the toxicity of IGR insecticides to achieve a better understanding of their mode of action. As a result, pyriproxyfen was the most potent IGR insecticide (EC50 = 0.049 ng/ml) followed by lufenuron, novaluron, and diflubenzuron according to the IGR bioassay. Further, based on the acute bioassay, lufenuron was the most toxic IGR insecticide (LC50 = 44 ng/ml) after 24-h post treatment followed by pyriproxyfen, novaluron, and diflubenzuron (LC50 = 137, 263, and 1127 ng/ml, respectively). Similar tendency was observed after 48 and 72-h post treatment. Furthermore, OR agonists that combined with pyriproxyfen was the most significant effects after 48 and 72-h of exposure. The synergism with amitraz (AMZ) was more significant when co-treated with IGR insecticides compared to chlordimeform (CDM). These findings suggest that OR agonists are promising tools and are important alternative strategies as synergistic compounds in preventing and controlling Culex quinquefasciatus mosquitoes.

Abstract
The use of conventional pesticides becomes a complicated issue as more species of insect pests become resistant to them. Nanopesticides suit new approaches in pest control. Herein, we tested the toxicological efficacy of imidacloprid compared with three of its nanoformulations (IMD01, IMD02, and IMD03) on second and fourth instar of Culex pipiens larvae. Furthermore, we assessed the synergistic actions of piperonyl butoxide (PBO) on imidacloprid and its nanoformulations against second and fourth instar of C. pipiens. The nanoformulation (IMD03) was the most potent insecticide (LC50 = 14, 6, and 2 ng/mL after 24, 48, and 72 h of exposure, respectively), whereas the lowest toxic nanoformulation was IMD01. However, imidacloprid had the lowest toxicity among the tested compounds (LC50 = 1015, 705, and 621 ng/mL after 24, 48, and 72 h of exposure, respectively). PBO significantly synergized imidacloprid and its nanoformulations. However, the most synergistic effects were on IMD03 and the lowest was imidacloprid itself. Based on our results, nanopesticides are currently the most promising tool to control C. pipiens mosquitoes. However, further semifield and field studies should be done to illustrate the efficacy of imidacloprid and its nanoformulations on C. pipiens mosquitoes.

Abstract
Standard chemical insecticides present mainly neurotoxic effects and are becoming less and less effective due to insects developing resistance to them. One of the innovative strategies to control insects pests is to find a way to increase the sensitivity of the target sites in the insect nervous system to the applied insecticides. In the presented research, we proposed menthol, a component of essential oils, as a factor increasing the effectiveness of bendiocarb, a carbamate insecticide. The aim of our study was to evaluate the potentiation of the bendiocarb effect by menthol. In toxicity tests performed on Periplaneta americana, menthol (0.1 μM) accelerated the lethal effect of bendiocarb, primarily in its low concentrations (lower than 0.05 mM). In the presence of menthol (1 and 0.1 μM), the ability of insects to turn back from its dorsal to the normal ventral side was significantly lower than with bendiocarb (1 μM) alone. We also evaluated the effectiveness of chemicals on the activity of the ventral nerve cord of the cockroach. In this preparation, bendiocarb (1 μM and higher concentrations) caused an irregular, spontaneous bursts of action potentials. The total nerve activity (including the response to stimulation and spontaneous firing) was much higher when bendiocarb was applied in the presence of menthol (1 μM). The effect of menthol was similar to the octopamine effect and was abolished by phentolamine, the octopamine receptor antagonist. Our results clearly indicated a strengthening effect of menthol on bendiocarb effectiveness; potentiation occurred through octopamine receptors activation.

Abstract
BACKGROUND Cytochrome P450 monooxygenases play an important role in the metabolic detoxification of insecticides in insect pests. However, little is known about the role of a specific P450 gene and its responses to insecticide exposure in Bradysia odoriphaga, a major pest in Chinese chive production. RESULTS In this study, a novel P450 gene, CYP3356A1, was cloned from Bradysia odoriphaga. The full-length cDNA sequence of CYP3356A1 is 2153 bp and its open reading frame (ORF) encodes 508 amino acids. Quantitative real time PCR(qRT-PCR) analyses in different tissues showed that CYP3356A1 expression was the highest in the Malpighian tubule. Moreover, among the different developmental stages of the insect, the highest expression of CYP3356A1 was found in fourth-instar larvae. Expression of CYP3356A1 was upregulated by treatment with imidacloprid, thiamethoxam, and β-cypermethrin at median lethal concentrations (LC50 ). RNA interference (RNAi)-mediated silencing of CYP3356A1 significantly increased mortality by 36.90%, 25.17%, and 36.73 when fourth-instar B. odoriphaga larvae were exposed to imidacloprid, thiamethoxam, and β-cypermethrin, respectively, at the LC50 dose. CONCLUSION These results demonstrate that CYP3356A1 is related to the detoxification of imidacloprid, thiamethoxam, and β-cypermethrin in B. odoriphaga. Moreover, the study also increased our understanding of the molecular mechanisms of insecticide detoxification in this pest insect. © 2018 Society of Chemical Industry.

Abstract
Quercetin as one of the key plant secondary metabolite flavonol is ubiquitous in terrestrial plants. In this study, the decrease in sensitivity to lambda-cyhalothrin was observed in quercetin-fed Helicoverpa armigera larvae. In order to figure out the mechanisms underlying the decreased sensitivity of H. armigera larvae to lambda-cyhalothrin by quercetin induction, the changes in carboxylesterase activity and in-vitro hydrolytic metabolic capacity to lambda-cyhalothrin were examined. The LC50 value of quercetin-fed H. armigera larvae to lambda-cyhalothrin showed 2.41-fold higher than that of the control. S, S, S-Tributyl phosphorotrithioate (DEF) treatment showed a synergism effect on lambda-cyhalothrin toxicity to quercetin-fed H. armigera. Moreover, the activity of carboxylesterase was significantly higher in quercetin-fed H. armigera larvae after fed on quercetin for 48 h. The in-vitro hydrolytic metabolic capacity to lambda-cyhalothrin in quercetin-fed H. armigera larvae midgut was 289.82 nmol 3-PBA/mg protein/min, which is significant higher than that in the control group (149.60 nmol 3-PBA/mg protein/min). The elevated CarE enzyme activity and corresponding increased hydrolytic metabolic capacity to lambda-cyhalothrin in quercetin-fed H. armigera contributed to the enhanced tolerance to lambda-cyhalothrin.

Int J Mol Sci 2016; 17:ijms17101577. [PMID: 27669213 PMCID: PMC5085626 DOI: 10.3390/ijms17101577] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2016] [Revised: 09/04/2016] [Accepted: 09/13/2016] [Indexed: 11/16/2022] Open
Abstract
The biogenic amine octopamine plays a critical role in the regulation of many physiological processes in insects. Octopamine transmits its action through a set of specific G-protein coupled receptors (GPCRs), namely octopamine receptors. Here, we report on a β-adrenergic-like octopamine receptor gene (BdOctβR1) from the oriental fruit fly, Bactrocera dorsalis (Hendel), a destructive agricultural pest that occurs in North America and the Asia-Pacific region. As indicated by RT-qPCR, BdOctβR1 was highly expressed in the central nervous system (CNS) and Malpighian tubules (MT) in the adult flies, suggesting it may undertake important roles in neural signaling in the CNS as well as physiological functions in the MT of this fly. Furthermore, its ligand specificities were tested in a heterologous expression system where BdOctβR1 was expressed in HEK-293 cells. Based on cyclic AMP response assays, we found that BdOctβR1 could be activated by octopamine in a concentration-dependent manner, confirming that this receptor was functional, while tyramine and dopamine had much less potency than octopamine. Naphazoline possessed the highest agonistic activity among the tested agonists. In antagonistic assays, mianserin had the strongest activity and was followed by phentolamine and chlorpromazine. Furthermore, when the flies were kept under starvation, there was a corresponding increase in the transcript level of BdOctβR1, while high or low temperature stress could not induce significant expression changes. The above results suggest that BdOctβR1 may be involved in the regulation of feeding processes in Bactrocera dorsalis and may provide new potential insecticide leads targeting octopamine receptors.

PEST MANAGEMENT SCIENCE 2016; 72:1051-8. [PMID: 26395964 DOI: 10.1002/ps.4155] [Citation(s) in RCA: 45] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/22/2014] [Revised: 09/12/2015] [Accepted: 09/16/2015] [Indexed: 05/23/2023]
Abstract
BACKGROUND Imidacloprid is a principal insecticide for controlling rice planthoppers worldwide. Resistance to imidacloprid has been reported in a field population of Laodelphax striatellus. The present work was conducted to study the molecular mechanisms of imidacloprid resistance. RESULTS An imidacloprid-resistant strain was produced by selecting a field population with imidacloprid for 24 generations. Piperonyl butoxide (PBO) showed a 1.70-fold synergistic effect. Enzyme activity assays were conducted, and cytochrome P450 monooxygenase showed 1.88-fold activity. The mRNA expression levels of 57 P450 genes were compared. Four CYP genes were found to be overexpressed and significantly different to the susceptible strain. Four strains were selected with imidacloprid for a short period, and the expression levels of ten identified detoxification genes were then compared. Only CYP353D1v2 overexpressed and was significantly different to the susceptible strain. Strong correlation was found between CYP353D1v2 expression levels and imidacloprid treatments. Additionally, gene-silencing RNAi via dsRNA feeding showed that depressing the expression of CYP353D1v2 could significantly enhance the sensitivity of L. striatellus to imidacloprid. CONCLUSION Constitutive overexpression of four CYP genes was associated with imidacloprid resistance in long-term selection, and expression of CYP353D1v2 with imidacloprid resistance in short-term selection in L. striatellus.

The role of octopamine receptor agonists in the synergistic toxicity of certain insect growth regulators (IGRs) in controlling Dengue vector Aedes aegypti (Diptera: Culicidae) mosquito. Acta Trop 2016; 155:1-5. [PMID: 26672383 DOI: 10.1016/j.actatropica.2015.11.015] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2015] [Revised: 11/17/2015] [Accepted: 11/27/2015] [Indexed: 11/16/2022]
Abstract
The synergistic action of octopamine receptor agonists (OR agonists) on many insecticide classes (e.g., organophosphorus, pyrethroids, and neonicotinoids) on Aedes aegypti L. has been reported recently. An investigation of OR agonist's effect on insect growth regulators (IGRs) was undertaken to provide a better understanding of the mechanism of action. Based on the IGR bioassay, pyriproxyfen was the most potent IGR insecticide tested (EC50=0.0019ng/ml). However, the lethal toxicity results indicate that diafenthiuron was the most potent insecticide (LC50=56ng/cm(2)) on A. aegypti adults after 24h of exposure. The same trend was true after 48 and 72h of exposure. Further, the synergistic effects of OR agonists plus amitraz (AMZ) or chlordimeform (CDM) was significant on adults. Among the tested synergists, AMZ increased the potency of the selected IGRs on adults the greatest. As results, OR agonists were largely synergistic with the selected IGRs. OR agonists enhanced the lethal toxicity of IGRs, which is a valuable new tool in the field of A. aegypti control. However, further field experiments need to be done to understand the unique potential role of OR agonists and their synergistic action on IGRs.
