Identification and characterization of three chemosensory receptor families in the cotton bollworm Helicoverpa armigera.

ABSTRACT:

Background

Chemosensory receptors including olfactory receptors (ORs), gustatory receptors (GRs) and ionotropic receptors (IRs) play a central role in sensing chemical signals and guiding insect behaviours, and are potential target genes in insect pest control. The cotton bollworm Helicoverpa armigera is one of the most destructive pest species that can feed on over 200 different plant species. This diversity of host plants is likely linked to a complex chemosensory system. Here we built on previous work to characterize crucial chemosensory tissues linked to environmental interactions including larval antennae, larval mouthparts and larval fat bodies, as well as male and female adult heads, male and female adult tarsi, and female abdomens.
