Abstract

The present study was done to know the efficacy of sub lethal doses Insecticides on mustard aphid, L. erysimi Kalt under laboratory conditions. Results revealed that the highest mortality of L erysimi were observed 100 % (Cypermethrin 10EC and Dimethoate 30 EC) followed by 93.33% (Thiamethoxam 25 WG, Imidacloprid 70 WG ), 86.67% (Acetamiprid 20 SP), 73.33% (Chlorantraniliprole 18.5 SC, Fenpyroximate 5 SC), 60% (Pyriproxyfen 10 EC, Fipronil 5 SC) at 72 Hrs after treatment in 0.001% concentration. At 72 Hrs after treatment in 0.002% concentration the highest mortality were observed 100% (Cypermethrin 10EC, Chlorantraniliprole 18.5 SC and Dimethoate 30 EC) followed by 93.33% (Lambda cyhalothrin 5EC, Imidacloprid 70 WG), 86.67% (Thiamethoxam 25 WG), 60% (Pyriproxyfen 10 EC), 80% (Fenpyroximate 5 SC), 73.33% (Fipronil 5 SC), 66.67% (Pyriproxyfen 10 EC, Acetamiprid 20 SP). Whereas Treated with 0.003% the highest mortality were observed 100% (Dimethoate 30 EC, Chlorantraniliprole 18.5 SC, Lambda cyhalothrin 5EC, Imidacloprid 70 WG Cypermethrin 10 EC) followed by 93.33% (Thiamethoxam 25 WG, Fenpyroximate 5 SC), 80% (Acetamiprid 20 SP, Pyriproxyfen 10 EC) and lowest 66.67% mortality recode in treated with Fipronil 5 SC.

亚致死剂量杀虫剂对芥菜蚜的防治效果

在实验室条件下，研究了亚致死剂量杀虫剂对芥菜蚜的防治效果。结果显示，在0.001%的浓度下，72 h后的死亡率最高的是氯氰菊酯10EC和乐果30ec，死亡率为100%，其次是噻虫嗪25wg、吡虫啉70wg，死亡率为86.67%，氯虫腈18.5 SC、苯螨酯5 SC，死亡率为73.33%，吡虫腈10EC、氟虫腈5sc，死亡率为60%。在0.002%浓度下，72 h死亡率最高为100%(氯氰菊酯10EC、氯虫腈18.5 SC、乐果30 EC)，其次为93.33%(高效氯氰菊酯5EC、吡虫啉70 WG)、86.67%(噻虫嗪25 WG)、60%(吡虫腈10EC)、80%(吡虫腈5 SC)、73.33%(氟虫腈5 SC)、66.67%(吡虫腈10EC、啶虫脒20 SP)。0.003%处理的死亡率最高为100%(乐果30 EC、氯虫腈18.5 SC、氯氟氰菊酯5EC、吡虫啉70 WG、氯氰菊酯10 EC)，其次为93.33%(噻虫嗪25 WG、芬吡肟5 SC)、80%(啶虫脒20 SP、吡虫腈10 EC)，氟虫腈5 SC的死亡率最低为66.67%。
