Presence of Female Sex-Attractant Pheromone in the Soybean Beetle, Anomala rufocuprea MOTSCHULSKY (Coleoptera: Scarabaeidae) and Its Bioassay with Walking Male

Abstract

A sex-attractant pheromone was found to be secreted by females of the soybean beetle. Anomala rufocuprea MOTSCHULSKY (Coleoptera: Scarabaeidae). The pheromone was collected on Tenax GC and Porapak Q and recovered with hexane. A laboratory bioassay method based on the orientation behavior of walking males in a glass tube was established.
