摘要
对杨扇舟蛾幼虫的取食量及成虫羽化节律进行研究。结果表明:随着龄期的增大,幼虫的取食量逐渐增多,取食速度也逐步加快;成虫的羽化主要集中在第7天,在24 h内,羽化高峰期主要集中在20:00左右,羽化率为84.5%。
Studied larval feeding amount and the emergence rhythm in Clostera anachoreta（Fabricius）.The results showed that the larval feeding amount was gradually increasing and the rate of larval feeding was escalating from 1st～5th larva.Emergence rhythm mainly occurred to seventh day in whole pupae stage（9 d）,and the peak emergence happened to 20：00 in one day（24 h）,the rate of emergence was 84.5%.
