Abstract

In a trapping study conducted in the experimental research forest of the Tohoku Research Center, Morioka, Honshu, Japan, we investigated the effect of heterospecific pheromone on pheromonal attraction of male Japanese gypsy moth, Lymantria disparjaponica (Motschulsky), and male pink gypsy moth, L. mathura Moore (Lepidoptera: Noctuidae: Lymantriinae). Traps baited with synthetic pheromone of L. d. japonica ((7R,8S)-cis-7,8-epoxy-2-methyloctadecane = (+)-disparlure (100 µg)) or L. mathura ((9R,10S,3Z,6Z)-cis-9,10-epoxynonadecadiene = (+)-mathuralure (20 µg) and (9S,10R,3Z,6Z)-cis-9,10-epoxynonadecadiene = (−)-mathuralure (80 µg)) attracted male L. d. japonica or L. mathura, respectively. Traps baited with synthetic pheromone of both species captured significantly fewer male L. mathura than traps baited solely with synthetic L. mathura pheromone. Numbers of male L. d. japonica captured in traps baited with (+)-disparlure were unaffected by the addition of L. mathura pheromone. (+)-Disparlure is a behavioral antagonist to pheromonal attraction of male L. mathura, whereas male L. d. japonica are indifferent to the presence of synthetic L. mathura pheromone.

Résumé

Dans une étude de piégeage réalisée dans la forêt expérimentale de recherche du Centre de recherche de Tohoku (Morioka, Honshu, Japon), nous avons examiné les effets de la phéromone hétérospécifique sur l’attraction phéromonale des mâles de la spongieuse japonaise, Lymantria dispar japonica (Motschulsky) et de la spongieuse rose, L. mathura Moore (Lepidoptera: Noctuidae: Lymantriinae). Les pièges garnis de phéromone synthétique de L. d. japonica ((7R,8S)-cis-7,8-époxy-2-méthyloctadécane = (+)-disparlure (100 µg)) ou de L. mathura ((9R,10S,3Z,6Z)-cis-9,10-époxynonadécadiène = (+)-mathuralure (20 µg) et (9S,10R,3Z,6Z)-cis- 9,10-époxynonadécadiène = (−)-mathuralure (80 µg)) attirent respectivement les mâles de L. d. japonica et ceux de L. mathura. Les pièges garnis des phéromones synthétiques des deux espèces capturent significativement moins de mâles de L. mathura que les pièges garnis seulement de la phéromone synthétique de L. mathura. Les captures de L. d. japonica dans les pièges munis de (+)-disparlure ne sont pas affectées par l’addition de la phéromone de L. mathura. Le (+)-disparlure est un antagoniste comportemental de l’attraction phéromonale des mâles de L. mathura, alors que les mâles de L. d. japonica restent indifférents à la présence de la phéromone synthétique de L. mathura.
