利用性诱剂调查江苏无锡地区三个水蜜桃Prunus persica种植区梨小食心虫Gtapholitha molesta成虫的年发生动态,并比较不同时间挂放诱芯的诱集效果。结果表明,在无锡地区,梨小食心虫年发生5代,部分发育较快的五代幼虫在越冬前发育为成虫,但因无法找到合适的产卵场所而成为无效虫口。越冬代成虫和一代成虫发生较为整齐,可以使用性诱剂集中诱杀,但从二代成虫开始,发生呈现多个高峰,田间世代重叠明显。对梨小食心虫的性诱剂防治试验表明,在无锡地区,需高密度放置诱芯并2周更换1次诱芯方能达到防治效果。
利用性誘劑調查江囌無錫地區三箇水蜜桃Prunus persica種植區梨小食心蟲Gtapholitha molesta成蟲的年髮生動態,併比較不同時間掛放誘芯的誘集效果。結果錶明,在無錫地區,梨小食心蟲年髮生5代,部分髮育較快的五代幼蟲在越鼕前髮育為成蟲,但因無法找到閤適的產卵場所而成為無效蟲口。越鼕代成蟲和一代成蟲髮生較為整齊,可以使用性誘劑集中誘殺,但從二代成蟲開始,髮生呈現多箇高峰,田間世代重疊明顯。對梨小食心蟲的性誘劑防治試驗錶明,在無錫地區,需高密度放置誘芯併2週更換1次誘芯方能達到防治效果。

The occurrence dynamics of Gtapholitha molesta in three peach pear growing regions in Wuxi, Jiangsu Province, were investigated by using oriental fruit moth sex pheromone; the sex pheromone lure effectively hang time by hanging lures at different times was illustrated;the effect of sex pheromone lure density on control of oriental fruit moth was tested. The results showed that oriental fruit moth occurred five generations in Wuxi, part of the larvae of fifth generation could develop into adults before wintering, but could not find a suitable place to spawn and became invalid insect population. Both of overwintering generation adults and first generation adults occurred with one peak. So the sex pheromone trapping could be used in control of these two generations. There were multiple peaks appeared since the second generation adults, which mean field overlapping generations of population were monitored in following generations.
