Abstract:

The G protein coupled receptors (GPCRs), known as transmembrane receptors, play an important role in drug research and development by activating G protein involved in inside signal transduction pathways. In present study, the full length cDNA of GPCR (namely LdOA1) was isolated from Lymantria dispar transcriptome. The open reading frame (ORF) of LdOA1 was 453 bp encoding a protein of 150 amino acid residues with the molecular mass of 17.54 kDa and theoretical pI of 9.76. Phylogenetic analysis of GPCR proteins showed LdOA1 of L. dispar clustered into a group with Danaus plexippus. We further investigated the expression of LdOA1 in 3rd instar L. dispar larvae under deltamethrin, carbaryl and omethoate stresses using real-time PCR. The results showed that LdOA1 in L. dispar was obviously inhibited by deltamethrin, carbaryl and omethoate.

Key words: Lymantria dispar, LdOA1, insecticide, gene expression
