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 micro-spray method was used to study the toxic effects of 6 insecticides Kangtang, deltamethrin, deltamethrin, beta-cypermethrin, abamectin and trichlorfon on the 3rd instar larvae of tobacco leafstalk. The results showed that the six insecticides were the best ones to kill KT, and the mortality was 96.67% when treated with 4000 g of 200 g · L -1 Kuan Kuan suspension for 8 days. No one pupation; trichlorfon on tobacco powdery mildew larvae also has a good poison killing effect, with 90% crystal 1000 times 8 d after treatment larvae mortality was 83.33%, significantly higher than deltamethrin, cyanide Intrusive and beta-cypermethrin three kinds of agent treatment. Kang Kuan can be used as an excellent smoke protection agent for the control of tobacco silt moths.
