Ectropis obliqua , a notorious tea pest, produces a Type-II sex pheromone blend for mate communication. This blend contains ( Z,Z,Z )-3,6,9-octadecatriene, ( Z,Z )-3,9- cis -6,7-epoxy-octadecadiene, and ( Z,Z )-3,9- cis -6,7-epoxy-nonadecadiene. To elucidate the genes related to the biosynthesis of these sex pheromone components, transcriptome sequencing of the female E. obliqua pheromone gland and the abdomen without pheromone gland was performed. Comparative RNAseq analyses identified 52 putative genes, including 7 fatty acyl-CoA elongases (ELOs), 9 fatty acyl-CoA reductases (FARs), 1 decarbonylase (DEC), 3 lipophorins (LIPs), and 32 cytochrome P450 enzymes (CYPs)...
