Expression profiles and functional prediction of ionotropic receptors in Asian corn borer, Ostrinia furnacalis (Lepidoptera: Crambidae)
Published 2022-02-01Get full textGenes involved in chemosensation are essential for odorant-mediated insect behaviors. Odorant receptors (ORs) bind and respond to pheromones and plant volatiles, regulating insect behaviors such as mating and host-plant selection, while ionotropic receptors (IRs), which are present at lower levels i...

Mutagenesis of odorant coreceptor Orco reveals the distinct role of olfaction between sexes in Spodoptera frugiperda
Published 2023-07-01Get full textOdorant receptor (OR) is crucial for insects to detect and recognize external chemical cues closely related to their survival. The insect OR forms a heteromeric complex composed of a ligand-specific receptor and a ubiquitously odorant receptor coreceptor (Orco). This study used the CRISPR/Cas9 techn...

Functional characterization of (E)-β-caryophyllene synthase from lima bean and its up-regulation by spider mites and alamethicin
Published 2017-10-01Get full textAbstract: (E)-β-Caryophyllene is a sesquiterpene compound widely distributed in plants and functions in plant defence. However, little is known about the sequence and function of (E)-β-caryophyllene synthase in lima bean (Phaseolus lunatus). Here, we report a new full-length cDNA (PlCAHS) encoding (...

Nicotinic Acetylcholine Receptor Gene Family of the Pea Aphid, Acyrthosiphon pisum
Published 2013-11-01Get full textThe nicotinic acetylcholine receptors (nAchRs) are cholinergic receptors that form ligand-gated ion channels by five subunits in insect and vertebrate nervous systems. The insect nAChR is the molecular target of a class of insecticides, neonicotinoids. Here, we identified and cloned 11 candidate nAC...

Ligand-binding properties of three odorant-binding proteins of the diamondback moth Plutella xylostella
Published 2016-03-01Get full textStrategies for insect population control are currently targeting chemical communication at the molecular level. The diamondback moth Plutella xylostella represents one of the most serious pests in agriculture, however detailed information on the proteins mediating olfaction in this species is still...

A conserved odorant receptor identified from antennal transcriptome of Megoura crassicauda that specifically responds to cis-jasmone
Published 2022-07-01Get full textHerbivore-induced plant volatiles (HIPVs) play a key role in the interactions between plants and herbivorous insects, as HIPVs can promote or deter herbivorous insects’ behavior. While aphids are common and serious phloem-feeding pests in farmland ecosystems, little is known about how aphids use the...

Light intensity regulates the sexual behaviors of oriental fruit fly Bactrocera dorsalis under laboratory conditions
Published 2023-09-01Get full textThe oriental fruit fly, Bactrocera dorsalis (Hendel), is a devastating pest of citrus fruits. After successful mating, adult females insert their eggs into the ripened fruit, resulting in moldy and rotten fruit and causing great economic losses for the citrus industry. In the field, flies initiate c...
