Abstract:		"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 and M. notatus to prevent cross attraction with each other. Volatiles were collected from males and females of M. s. scutellatus and M. notatus every 8 h and analyzed by coupled gas chromatography-mass spectrometry. Traps baited with monochamol and the host volatiles alpha-pinene and ethanol were checked every 8 h in field tests. Only male M. s. scutellatus produced the pheromone, and did so in similar quantities during each 8-h time interval assessed, suggesting there is no diel rhythm in pheromone production. In field tests conducted in early to mid-July, significantly more M. s. scutellatus were captured during morning hours, and significantly more M. notatus were caught during afternoon or early evening hours, suggesting temporal partitioning of flight or in their response to the pheromone lures when both species are present. A temporal switch occurred later in the seasonal flight period (mid-August) when densities of M. s. scutellatus were low; all M. notatus and only one M. s. scutellatus were caught during morning hours. This suggests a temporal separation in mate location behavior when both species are abundant and using the same host to avoid interspecific mating"
