Diel Rhythms inMonochamus(Coleoptera: Cerambycidae): Production of and Response to a Male-Produced Aggregation Pheromone

Recent research has shown that several species in the genus Monochamus , including Monochamus scutellatus scutellatus (Say) and Monochamus notatus (Drury), a close congener, are attracted to an aggregation pheromone, monochamol, but only M. s. scutellatus produces it. Investigations were conducted to determine if there is a diel rhythm in production of monochamol or response to monochamol + host attractants in field trials by M. s. scutellatus...
