摘要
观测了小地老虎的生活史，并用白僵菌对烟田小地老虎进行了防治试验。结果表明：云南省玉溪烟区小地老虎1年发生4代，以老龄幼虫和蛹在4～8cm土层中越冬；利用白僵菌防治烟田小地老虎效果显著，白僵菌对小地老虎的侵染死亡率在95％以上；校正死亡率为98．2％，施用白僵菌防治小地老虎的烟田中烟苗和烟株受害率显著下降。
The life history of Agrotis ypsilon Rottemberg was observed, and the control of Agrotis ypsilon Rottemberg in tobacco field with Beauveria bassiana was experimented. The results showed that there were 4 generations per year for Agrotis ypsilon Rottemberg and the aged larva and pupa overwintered in the soil depth of 4-8 cm; the effects of Beauveria bassiana on Agrotis ypsilon Rottemberg controlling in field were obvious, the infected mortality was over 95 % and corrected mortality was 98.2 %, and the attacked seedlings and plants in test tobacco field decreased significantly
