Does the Difference in the Aggregation-Sex Pheromone Release Pattern Between Monochamus alternatus Hope (Coleoptera: Cerambycidae) and Monochamus saltuarius Gebler Ensure Reproductive Isolation in the Cohabitation Area?

ABSTRACT: In our study, we analyzed diel, daily, and weekly pheromone emission patterns to determine whether pheromone release pattern may facilate reproductive isolation between two species that use the same aggregation-sex pheromone, namely Monochamus alternatus Hope (Coleoptera: Cerambycidae) and Monochamus saltuarius Gebler, (Coleoptera: Cerambycidae) in areas where they are sympatric. The daily emission of monochamol by males of both species showed irregular but constant patterns, with M. saltuarius males releasing the pheromone earlier than their M. alternatus counterparts after cuticular sclerotization. The first emission of the pheromone occurred, on average, 10.6 and 5 days after sclerotization for M. alternatus and M. saltuarius, respectively. Weekly patterns of monochamol emission showed
