摘要
采用微量喷雾法,研究了康宽、溴氰菊酯、甲氰菊酯、高效氯氰菊酯、阿维菌素和敌百虫6种杀虫剂对烟草粉螟3龄幼虫的室内毒杀效果。结果表明,6种杀虫剂以康宽的毒杀效果最佳,用200 g·L-1康宽悬浮剂4000倍液处理后饲喂8 d,烟草粉螟幼虫死亡率为96.67%,且无一化蛹;敌百虫对烟草粉螟幼虫也具有较好的毒杀效果,用90%晶体1000倍液处理8 d后幼虫死亡率为83.33%,显著高于溴氰菊酯、甲氰菊酯和高效氯氰菊酯3种药剂处理。康宽可作为一种优良的贮烟防护剂用于防治烟仓烟草粉螟。
The indoor poisonous effects of six insecticides, namely kang-kuan, deltamethrin, fenpropathrin, beta-cypermethrin, avermectins and dipterex, on the 3th larva ofEphestia elutella （Htibner） were studied by means of micro-spray. The result indicated that the poisonous effect of kang-kuan was the best insecticide, and the mortality rate of larva with post-treatment for 8 days was 96.67% after treated with 4000 times diluent of kang-kuan deflocculant of 200 g·L-1, and none of the larva pupated in the end. The dipterex had good poisonous effect on the tested larva as well, and the mortality rate of the larva was 83.33% after treated with 1000 times diluent of 90% content of dipterex crystalloid, which was markedly higher than those of deltamethrin, fenpropathrin and beta-cypermethrin. As an excellent protectant for stored tobacco, the insecticide kang-kuan should be widely applied into the control ofE. elutella larva.
