摘要
甘蔗二点螟以幼虫休眠和滞育两种方式越冬，年发生１－４代。采用＂控制虫源、压低基数＂的防治策略，与过去＂狠治第１代，压基数＂的防治策略相比，成熟期虫蛀节率相差２５倍以上。农业防治对该虫防治有重要意义，能起到化学防治所起不到的作用。化学防治主攻对象是越冬后的越冬代幼虫和休眠越冬的第１代蚁螟。
Millet borer(Chilo infuscatellus)in sugarcane occuring from 1 to 4 generations per year live through the winter in two modes,larva dormancy and stagmancy.Bored node rate adopting former control strategy,Controlling the First Generation,Cutting Down Base Number, is 25 times more than that of Controlling the Overwintering Insect source, Reducing Overwintering Number. Agricultural control methods have important influence on controlling it and the management efficiency which chemical control can't do.Optimal target of chemical control is overwintered generation larve and the first generation younger larva occuring from dormancy overwintered generation after winter.
