摘要
穴蚁蛉在自然条件下1年发生1代，本实验证明，不同的饲食频率可影响幼虫的发有历期，在每天饲给1头米蛾成虫的情况下，1年可发生3代。1个世代可以在全历期都处于长日照和没有低温的条件下完成，其发育可以不需要光周期变化和低温的诱发。15口饲食1次的穴蚁岭，3龄幼虫在秋季后发生越冬分化，少数在冬前完成发育为成虫，大部分延至翌年才能完成世代发育。
Wrmeleon sagax (Walker) completes one generation in a year in nature condihon. However, in labobory condihon, the feeding amount of larvae can affect its development three generations in one year were observed by providing sufficient food; one complete generation was observed from June to AugusL undr the long photoperiod and high temperature conditions. It was found that the third instar lareas differenhated after autumn by feeding once in a interval of 15 dnys, a few lareae could complete its development into adult and most of larvae delayed its development to the next year.
