摘　　要：淡剑夜蛾[Sidemia depravata（Butler）]在苏州地区年发生4-5代，以老熟幼虫和蛹在草坪草根基部附近浅土层中越冬，世代重叠，整个世代历期为34～35d，各虫态平均历期为：卵期3-4d，幼虫整个历期为19d，l-6龄分别为：4d、3d、3d、2d、2d、5d，预蛹期ld，蛹期6d，成虫期5d；成虫灯下始见于4月下旬，7月中旬开始数量突增，发蛾盛期持续到9月下旬。室内药效测定表明，1．5％世扬EC3000倍、4000倍，25％喹硫磷ECl000倍、15％阿维·毒ECl500倍，4．5％高效氯氰菊酯ECl500倍，10％除尽ECl000、2000倍，均有很高的活性，速效性好；田间药效试验表明，25％喹硫磷EC、4．5％高效氯氰菊酯EC、1．5％世扬EC、15％阿维·毒EC均取得了较好的防治效果。Sidemia depravata （Butler） is a serious pest damaging lawn in Suzhou, J iangsu Province. There are 4-5 generations per year. They overwinter as matured larva and pupae in the surface layer of oil near grass root on the lawn. The mean generation times were 34-35 d, and its egg period lasted about 3-4 days and its larval period lasted about 19 days. It＇s pre-pupae lasted 1 day. Its pupae period lasted about 6 days. It＇s adult stag lasted about 5 days. Adults captured by light traps appeared in the late April and prevailed from the middle July to the late September. The efficacy tests in laboratory showed that the control efficiency of 1.5 % A ammonia Emamectin benzoate EC at a dilution during 3000 and 4000,25 % Quinalphos EC at a dilution of 1000, 15 % Abamectin·Chlorpyrifos EC at a dilution of 1500,4.5 % Alphacypermethrin EC at a dilution of 1500,10 % Shujin EC at a dilution during 1000 and 2000 on the Sidemia depravata （Butler） was all good and instant. The field experiment results showed that the 25 % Quinalphos EC, 4.5 % Alphacypermethrin EC, 1.5 % ammonia Emamectin benzoate EC, 15 % Abamectin·Chlorpyrifos EC had better, longer and more stable control effect.
