摘要
本文报道甘薯烦夜蛾的生物学和防治方法。结果表明，在福建莆田沿海地区一年发生５代，少数６代，冬季无明显越冬现象。日均温２６．８℃：，相对湿度６１％，卵期３．１天，幼虫期１５．２天，蛹期１４．２天，成虫产卵前期１．８天，全代历期３４．３天。７－９月为幼虫大发生季节，危害早甘薯。幼虫共６龄。成虫单雌产卵量平均１１１粒。此虫天敌资源较为丰富，烦夜蛾多角体病毒ＮＰＶ很有利用价值。药剂测定，显示出５０％甲胺磷乳油防效最好，其次２．５％溴氰菊酯可湿性粉剂和８０％敌敌畏乳油，而１８％杀虫双水剂效果较差。
The biology of Anophia leucomelas and its control measure were studied.Thispest ,which is harmful to erly sweet potato,mainly occurs 5 genertions annually,exceptsome with 6 generations,and without distinct dorniancy in winter, The development time ofits egg,larva,pupa and preoviposition,under average diurnal temperature 26.8℃ andrelative humidity 61%, is 3.1,15.2,14.2 and 1. 8 days respectively and the toatl durationof a whole generation lasts 35 days.The larva can be divided into 6 instars and every femalecan produce 111 eggs in average,There are many natural enenlies on this pest,amongwhich,AI NPV possesses most promising effect for partical use. Insecticide test inlaboratory indicates that 50%methamidophos has the most effective,2.5%deltamethrinand 80%DDVP range second,and 18%shachongshuang shows poor effects for the controlof this pest.
