Screening of olfactory genes related to blood-sucking behavior by transcriptome analysis between Culex pipiens quinquefasciatus and Culex pipiens molestus

Culex pipiens quinquefasciatus (Cx. quinquefasciatus) and Culex pipiens form molestus (Cx. molestus) in the Culex pipiens Complex group show significant differences in host-seeking blood-sucking, mating and vector competence. The blood-sucking behavior of mosquitoes is closely related to the olfactory gene expression. The comparison of olfactory genes between the two subspecies with significantly different blood-sucking behaviors can lay the foundation for further elucidating the molecular mechanism of the olfactory sensory system of Culex pipiens quinquefasciatus, providing new approach on candidate compounds for attractants or repellents.
