The egg parasitoid Telenomus euproctidis (Hymenoptera: Scelionidae) uses sex pheromone released by immobile female tussock moth Orgyia postica (Lepidoptera: Lymantriidae) as kairomone

摘要

Egg parasitoids Telenomus euproctidis Wilcox (Hymenoptera: Scelionidae) were attracted to egg masses laid by wingless immobile female Orgyia postica (Lepidoptera: Lymantriidae). Virgin females, a solvent extract of pheromone glands, and a synthetic sex pheromone, (6Z,9Z,11S,12S)-11,12-epoxyhenicosa-6,9-diene (posticlure), also attracted this parasitoid in the field, demonstrating that T. euproctidis uses the sex pheromone of female Org. postica as a kairomone to locate host eggs.
