探讨温度对涤虫剂杀灭蚊虫作用的影响对合理使用杀虫剂,提高防蚊灭蚊效果都具有十分重要的参考价值。作者在实验室用标准浸渍法对淡色库蚊(Culex pipienspallens)四龄幼虫用6种拟除虫菊酯进行处理,每种杀虫剂试验用两个浓度,各自作4—8个重复,试虫数量为100—200条。处理完毕分别置于20℃、25℃和30℃的恒温箱内,24小时后观察结果。幼虫以不能逃避机
To explore the impact of temperature on mosquitoes to kill mosquito insects on the rational use of insecticides, mosquito control to enhance mosquito effects have a very important reference value. The authors treated six species of pyrethrum-resistant Culex pipiens pallens in laboratory using standard dipping methods. Each insecticide was tested in 4-8 replicates at two concentrations, the number of test insects For 100-200. After treatment were placed in 20 ℃, 25 ℃ and 30 ℃ incubator, 24 hours after the observation results. Larvae can not escape the machine
