摘要
本文分别对3种不同成分市售胶饵防治德国小蠊的杀灭效果和6种药剂的室内滞留药效进行评价,以指导现场防治。胶饵室内药效实验采用玻璃方箱法,以死亡率评价杀灭效果;室内滞留药效实验采用果酱瓶药膜法,以德国小蠊与药膜强迫接触20 min后的死亡率评价室内滞留药效。结果显示,3种胶饵在施用96 h后,试虫校正死亡率均达到了100%,3种药剂药效均达到A级。6种滞留喷洒用药剂对德国小蠊的实验室杀灭效果均达到100%,持效期90 d以上。结果表明,9种药剂在实验室条件下对德国小蠊均具有良好的杀灭效果,在现场防治中可以根据实际情况合理选用。
The trapping and killing effects of three different components of gel baits and the residual spraying of six insecticides to Blattella germanica were evaluated in order to promote and guide on field prevention and control.In the laboratory efficacy test,the glass box method was used to evaluate the killing effect by mortality.The method of jam bottle film was used in the residual spraying experiment and the residual spraying efficacy was evaluated by the mortality of B.germanica after forced contact with the film for 20 minutes.The results showed that the mortality of all the three gel baits reached 100%after 96 h,all of the three gel baits reached“A”class.The killing effect of the six insecticides used for residual spraying to B.germanica reached 100%in laboratory,and the duration of efficacy was more than 90 days.The nine insecticides had good killing effect to B.germanica in laboratory,and could be reasonably selected according to the actual situation in the field prevention and control.
