Sex pheromone production and perception in the mating disruption‐resistant strain of the smaller tea leafroller moth, Adoxophyes honmai

摘要: Mating disruption is an environmentally safe plant protection strategy that uses a synthetic copy of insect pheromone to interfere with sexual communication and hence reproduction. To date, number pest moths have been controlled applications formulated pheromones as mating disruptants. Recently, however, the first example resistance was documented in one major tea pests Japan, smaller leafroller moth, Adoxophyes honmai Yasuda (Lepidoptera: Tortricidae). avoid other such cases, it important elucidate mechanism(s) by which disruptant lost its effectiveness. this end, we imposed further selection rearing field-collected resistant insects laboratory. After more than 70 generations selection, strain quite strong established, males could find copulate their mates even presence 1 mg l -1 disruptant. Although ability greatly increased, composition blend ratio sex produced emitted females were not obviously changed comparison those sensitive disruption. However, male response markedly broadened after so locate source when lacked component normally necessary for attraction. Males capable locking onto off-ratio blends may be better able calling pheromone-treated environments narrowly tuned because greater capability overcoming sensory imbalance.
