摘　　要：淡剑夜蛾一年发生4～5代,以老龄幼虫在草坪根部表面层越冬．1龄、2龄、3龄、4龄、5龄、6龄幼虫头壳宽分别为0．33±0．13mm,0．60±0．07mm,0．93±0．10mm,1．28±0．20mm,1．66±0．10mm,1．92±0．13mm．幼虫期总食叶量为52．17cm^2．雌雄性比1:1．24．在室外喷雾2000倍20%杀灭菊脂、2000倍20%米满、4000倍20%除虫脲、2000倍10%除尽、4000倍5%氯氰菊酯、1000倍25%灭幼脲三号和6000倍1%阿维菌素7d后的校正死亡率分别在85．60%～96．20%．Sidemia depravata has 4 or 5 generations a year in shanghai and overwinters as mature larva in the surface layer of lawn soil. The width of heedcapsue of the 1 st - 6th instar larva are 0.33 ＋- 0.13mm,0. 60 ＋- 0.07mm,0.93 ＋- 0.10mm, 1.28 ＋- 0.20mm, 1.66 ＋- 0.10mm, 1.92 ＋- 0.13mm, respectively. The total feeding area of larva is 52.17cm^2. The sexual ratio of female to male is 1： 1.24. The corrected mortality is between 85.60% - 96.20% seven days after spraying withl： 2000 dilution of 20% Fenvalemte,1： 2000 dilution of 20% Tebufenozide,1：4000 dilution of 20% Difubenzuron,1：2000 dilution of 10% Chu-jin, 1： 4000 dilution of 5% Cypermethyin,1： 2000 dilution of 1% Abamectin,1： 1000 dilution of 25% Benzoy Ipbenyl ureas under field test conditions.
