Abstract

BACKGROUND

Diamondback moth Plutella xylostella (L.) (Lepidoptera: Plutellidae) is one of the most important crucifer pests. Commercial sex attractants have been developed to monitor and control P. xylostella. However, some studies have demonstrated a variety of pheromone responses of P. xylostella in different locations of the world. Soluble pheromone‐binding proteins (PBPs), as a subfamily of odorant‐binding proteins (OBPs), could selectively bind and transport pheromones across aqueous sensillar lymph to the surface of olfactory receptor neurons. It is a worthy well study whether the mutation of PxylPBPs is one of the reasons for the different responses of sex attractors in different regions.
