HcGr76 responds to fructose and chlorogenic acid and is involved in regulation of peptide expression in the midgut of Hyphantria cunea larvae. PEST MANAGEMENT SCIENCE 2024.

Abstract
BACKGROUND Sensing dietary components in the gut is important to ensure an appropriate hormonal response and metabolic regulation after food intake. The fall webworm, Hyphantria cunea, is a major invasive pest in China and has led to significant economic losses and ecosystem disruption. The larvae's broad host range and voracious appetite for leaves make H. cunea a primary cause of serious damage to both forests and crops. To date, however, the gustatory receptors (Grs) of H. cunea and their regulatory function remain largely unknown. RESULTS We identified the fall webworm gustatory receptor HcGr76 as a fructose and chlorogenic acid receptor using Ca2+ imaging and determination of intracellular Ca2+ concentration by a microplate reader. Moreover, reverse transcription-quantitative polymerase chain reaction (RT-qPCR) analysis revealed that HcGr76 is highly expressed in the anterior and middle midgut. Knockdown of HcGr76 caused a significant reduction in the expression of neuropeptide F 1 (NPF1) and CCHamide-2, and led to a decrease in carbohydrate and lipid levels in the hemolymph. CONCLUSION Our studies provide circumstantial evidence that HcGr76 expressed in the midgut is involved in sensing dietary components, and regulates the expression of relevant peptide hormones to alter metabolism in H. cunea larvae, thus providing a promising molecular target for the development of new insect-specific control products. © 2024 Society of Chemical Industry.

Parasitoids as taxonomists: how does the parasitoid Chouioia cunea distinguish between a host and a non-host? PEST MANAGEMENT SCIENCE 2023; 79:4547-4556. [PMID: 37427488 DOI: 10.1002/ps.7656] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Revised: 06/25/2023] [Accepted: 07/10/2023] [Indexed: 07/11/2023]
Abstract
BACKGROUND How parasitoids distinguish hosts from non-hosts remains an unknown question. Chouioia cunea Yang (Eulophidae) is an important fall webworm parasitoid that attacks many forest and agricultural pests. To study the differences in the chemical clues used by C. cunea to distinguish host and non-host plants, we used gas chromatography-mass spectrometry (GC-MS) to identify volatile compounds of two C. cunea hosts (Hyphantria cunea and Helicoverpa armigera) and two non-hosts (Spodoptera exigua and Spodoptera frugiperda). Additionally, we used behavioral assays to compare the attraction of C. cunea to various compounds. RESULTS The two natural host species were more attractive than the two non-host species, in the following order: Hyphantria cunea > Helicoverpa armigera > S. exigua = S. frugiperda. The pupae of the natural hosts contained 1-dodecene, which was not produced by the two natural non-hosts. When the 'attractants' based on the difference between the species-specific blend emitted by pupae and the optimal blend were sprayed onto the natural non-host pupae, they significantly improved the attraction of C. cunea to the non-host pupae. CONCLUSION These results revealed that specific host-produced volatile compounds guide C. cunea to distinguish between natural hosts and non-hosts. Overall, this study provides a foundation for developing a behavior-modifying strategy to re-direct C. cunea attacks to control important non-host pests. © 2023 Society of Chemical Industry.

Volatile Organic Compounds from Cassava Plants Confer Resistance to the Whitefly Aleurothrixus aepim (Goeldi, 1886). INSECTS 2023; 14:762. [PMID: 37754730 PMCID: PMC10531547 DOI: 10.3390/insects14090762] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/01/2023] [Revised: 07/21/2023] [Accepted: 08/01/2023] [Indexed: 09/28/2023]
Abstract
Cassava is an essential tuber crop used to produce food, feed, and beverages. Whitefly pests, including Aleurothrixus aepim (Goeldi, 1886) (Hemiptera: Aleyrodidae), significantly affect cassava-based agroecosystems. Plant odours have been described as potential pest management tools, and the cassava clone M Ecuador 72 has been used by breeders as an essential source of resistance. In this study, we analysed and compared the volatile compounds released by this resistant clone and a susceptible genotype, BRS Jari. Constitutive odours were collected from young plants and analysed using gas chromatography-mass spectrometry combined with chemometric tools. The resistant genotype released numerous compounds with previously described biological activity and substantial amounts of the monoterpene (E)-β-ocimene. Whiteflies showed non-preferential behaviour when exposed to volatiles from the resistant genotype but not the susceptible genotype. Furthermore, pure ocimene caused non-preferential behaviour in whiteflies, indicating a role for this compound in repellence. This report provides an example of the intraspecific variation in odour emissions from cassava plants alongside information on odorants that repel whiteflies; these data can be used to devise whitefly management strategies. A better understanding of the genetic variability in cassava odour constituents and emissions under field conditions may accelerate the development of more resistant cassava varieties.

Abstract
Host-plant volatiles play vital roles for insects to locate foraging, mating, and oviposition sites in the environment. As one of the devastating invasive forestry pests, Hyphantria cunea causes a great annual loss in China, and understanding its chemical ecology is an important task. The current research was done in terms of chemical analysis, electrophysiology, and behavioral assays on H. cunea to assess its olfactory reception toward host-plant volatiles. A screen of possible common host volatiles was done, targeting on five favored hosts of H. cunea, harvesting six potential bioactive compounds from a total of 78 odorant components. Six types of antennal sensilla were investigated on their distributions on the antennae, and sexual dimorphism was described. H. cunea showed responses to all selected host-related volatiles in electroantennogram tests, and linalyl butyrate elicited the strongest responses. Furthermore, mating rates in adult pairs that are exposed to dibutyl phthalate and phytol have been significantly increased, while oviposition rates and female fecundity were not influenced. The results of the current study provide initial evidence showing that universal host-derived volatile cues are essential for H. cunea moth in terms of mating, which can also provide insights into the development of botanical attractants.

Abstract
BACKGROUND Chouioia cunea Yang (Hymenoptera: Eulophidae) is a parasitic wasp and natural enemy of several lepidopteran pests during their pupal stage. The volatiles from pupae of three hosts, Hyphantria cunea (Arctiidae), Antheraea pernyi (Saturniidae) and Lymantria dispar (Erebidae), were analyzed and compared to elucidate the chemical cues used by C. cunea to locate its hosts. RESULTS The attraction of C. cunea to H. cunea pupae has no obvious association with the types of plant leaves consumed by H. cunea before pupation. C. cunea exhibited the strongest attraction to the pupae of H. cunea, followed by those of A. pernyi and L. dispar based on behavioral experiments. Gas chromatography-mass spectrometry and GC-electroantennography (GC-EAD) analyses showed that these three host pupae consisted of essentially the same active volatile components but at different relative amounts. Active components derived from these pupae by GC-EAD were alkanes from C12 to C27, and C. cunea showed different levels of attraction to different single compounds. CONCLUSION Host location by C. cunea primarily depends on common compounds emanating from the pupae of several host species. The relative amount of each component varies across host species, guiding host preferences by C. cunea. Optimal blends of several components were identified. Understanding the chemical cues used by C. cunea to locate its host could increase the possibility of developing attractants for parasitic wasps and subsequently increasing the parasitism rate of C. cunea on various hosts. © 2019 Society of Chemical Industry.

INSECT BIOCHEMISTRY AND MOLECULAR BIOLOGY 2020; 117:103286.

Abstract
Chouioia cunea (Yang) is a pupal parasitoid wasp and this species is able to seek host insects depending on its olfactory system. However, the molecular mechanism of the olfactory system in the C. cunea is still limited. To identify putative semiochemicals bound to CcOBP2, a protein specifically expressed in antennae, 14 compounds from the pupae of H. cunea and 11 common volatile compounds from plants were selected for competitive fluorescence binding assay. The result of the binding assay showed that five compounds were able to bind toCcOBP2. The electroantennogram (EAG) demonstrated that the antennae had a significant response to the 3-Carene, a bicyclic monoterpene, and C. cunea could be obviously attracted by this compound. The behavioral response to 3- carene was dramatically weakened when CcOBP2 was specifically knocked down. The molecular docking result indicated that several amino acids especially Ile-81, Val-122, Phe-123 of CcOBP2 were responsible for binding to 3-Carene. Furthermore, there was a repellent effect on the host H. cunea with the treatment of the 3-Carene. This study illustrated that CcOBP2 might be a crucial protein involved in the olfactory signaling pathway and the 3-Carene, secreted from plants, could probably have a potential role in repelling pests as well as attracting natural enemies.

Abstract
Chouioia cunea (Yang) is an endoparasitic wasp which parasitizes pupae and thus plays an important role in the biological control of the fall webworm (Hyphantria cunea Drury), an important quarantine pest in the entire world and a major invasive pest in China. For the purposes of investigating which proteins are involved in the response of C. cunea to 1-Docecene, one of the chemical compounds of pupae of H. cunea with a significant attracting action to mated female C. cunea, 11.5 Gb transcriptome data was sequenced on the PacBio RS II platform from 1-day old C. cunea adults to generate a reference assembly. Afterwards, 46.88 Gb of clean RNA-Seq data were obtained to assess the transcriptional response of these insects before and after the stimulation with 1-Docecene. After removing redundancy using CD-HIT, a sequence structure analysis predicted 29,105 complete coding sequence (CDS) regions, 51,458 single-sequence repeats (SSRs), and 2,375 long non-coding RNAs. Based on the early transcriptome sequencing in our laboratory, we revealed some new sequences corresponding to chemosensory genes such as odorant binding proteins (OBPs), odorant receptor (OR), gustatory receptors(GRs). Results of quantitative real-time PCR experiments revealed that CcOBP7, CcOBP18, CcCSP4, CcOR2, and CcGR18 were up-regulated after 1-Dodecene stimulation. In addition, the expression of 31 genes, including 1 gene related to phospholipid biosynthesis and 2 genes related to transmembrane transport were up-regulated after 1-Dodecene stimulation; meanwhile, the expression of 22 genes, including 5 genes related to protein phosphorylation and protein serine/threonine kinase activity were significantly down-regulated after 1-Dodecene stimulation. These results suggest that the attraction of adult C. cunea to 1-dodecane is associated with the transmembrane signal transduction and dephosphorylation of some proteins. Our findings will provide useful targets for further studies on the molecular mechanism of host recognition in C. cunea.
