交信撹乱剤を処理したナシ園におけるフェロモントラップへのリンゴコカクモンハマキの誘殺と交信撹乱効果 Seasonal Capture in Pheromone Traps and Effect on Mating Disruption of Summer Fruit Tortrix Moth, Adoxophyes orana fasciata Walsingham, in Pheromone Treated Japanese Pear Orchard
Seasonal capture in pheromone traps of summer fruit tortrix moth, <i>Adoxophyes orana fasciata</i> Walsingham was investigated in Japanese pear orchards treated with mating disruptor in Chiba. <i>A. orana</i> population showed two peaks at late May and middle July in 2010, despite the existence of mating disruptor. In order to elucidate the cause of <i>A. orana</i> outbreak, the mating disruptor susceptibility of <i>A. orana</i> was examined. The mating rate in mating disruptor untreated plots ranged from 10.3 to 34.5%, while those in the pheromone treated plots were 0%. This result suggested that <i>A. orana</i> population in Chiba is not resistant to pheromone-based mating disruptor.
