Two closely related plusiinae moths, Autographa gamma Linnaeus and Cornutiplusia circumflexa Linnaeus, are sympatric in Israel. Both species use identical sex pheromone components but in different ratios, and do not attempt to mate with each other. In addition to the effective reproductive separation by their sex pheromones, the sexual behavior of both species was compared to determine whether the lack of selection pressure might create additional barriers to cross-attraction and cross-mating. We found the gamma moth to be sexually active almost equally throughout the scotophase, whereas the sexual activity of C. circumflexa was limited to a short period at the end of the scotophase when most of the gamma moths had already mated. Higher levels of calling were observed with older females. There was a close relationship between pheromone titer and calling activity in both species. © 2005 Springer Science + Business Media, Inc.
