Evidence of pheromone mediated behavior in the large pine weevil hylobius abietis coleoptera curculionidae

, : Evidence of pheromone mediated behavior in the large pine weevil hylobius abietis coleoptera curculionidae. Annales Entomologici Fennici 44(4): 105-112

Laboratory tests with H. abietis L. suggested the existence of 2 pheromones. Males collected during their flight period attracted other males and females, indicating that they produce an aggregation pheromone. Juvenile males attracted other juveniles of both sexes. Females ready to mate evidently released a sexual pheromone which aided sex recognition and stimulated the male to mount them. The pheromone system in H. abietis apparently involves the interaction of these 2 pheromones, similar to those for other curculionids.
