摘要：

枸杞负泥虫在信阳1年发生5代，以蛹在土中结白茧越冬。成虫来年4月中旬羽化后开始取食和交尾，以后各代成、幼虫为害颠茄草叶片，严重者甚至吃成渔网状。10月上旬幼虫入土结白茧化蛹越冬。疑有世代重叠现象。人工防治和0.5％大印乳油200mL／667m2喷雾效果好。

Abstract:

Lema decempunctata occurred 5 generations annually in Xinyang City, and overwintered in soil wtih pupa of white cocoon. Adults fed and mated in the next middle of April, and the adults and larvae of following generationgs damaged leaves of Atropa belladonna. The leaves were often eated to reticulation if this insect damaged seriously. Larvae produced white cocoon and pupated at soil in the early october, and generation overlapping maybe occurred. Artificial controlling and spraying 200mL/667m2 0.5% Dayin EC had good effect to Lema decempunctata.
