摘  要:
通过调查,首次发现黄杨绢野螟严重为害九里香。该虫在福建尤溪1 a发生1~4代,以第4代低龄幼虫和第1、2、3代休眠3龄幼虫在缀2~3片叶所结的薄茧内越冬。第1、2、3、4代幼虫孵化盛期分别为5月中旬、7月上旬、9月下旬和11月中下旬,成虫羽化盛期分别为6月下旬、9月中旬、11月上旬和翌年5月上旬。采用吡虫啉、功夫、啶虫脒乳油1 500倍液喷雾防治,校正死亡率均达91.8%以上。最佳防治时间为每年3月中旬~6月上旬。防治该虫应采用园艺防治、人工诱杀、植物检疫、生物防治和化学防治进行综合治理。

摘  要:
Diaphania perspectalis was found damaging Murraya paniculata first time.This species had 1~4 generations per year in Youxi Fujian.Its dormancy state was the 3-instar larvae of first to third generation enwrapped in the cocoon with 2~3 leaves or the fouth generation juvenile instar ones.The busy hatch periods of first,second,third and fourth generation were on the middle ten days of May,the first ten days of Jul.,the last ten days of Sep.and the middle and last ten days of Nov.,respectively,and the busy eclosion period were on the last ten days of Jun.,the middle ten days of Sep.,the first ten days of Nov.and the middle ten days of May next year,respectively.Irnidacloprid,clocythrin and acetamiprid diluted 1 500 folders were sprayed to control the pest,and the emendation mortality was 91.8%.The optimal control period was from the middle ten days of Mar.to the first ten days of Jun..The methods to control the pests were the integrated controls of horticultural control,artificial trap,plant quarantine and chemical control.
