摘要
目的:观察毒力岛胶饵防治德国小蠊的效果。方法:布药前后蟑螂密度观察。结果:施药前密度指数为5.25只/张·夜,施药后7、30和60d德国小蠊密度下降率分为89.62%,99.39%,97.78%。结论:毒力岛防治方法对德国小蠊灭效明显,持效时间长,且对环境无污染,值得推广应用。
Objective ：To observe the effect of Dulidao plastic bait on killing Blattella germanica. Methods：field application.Results：The density index was 5.25 pieces per box per night. The density reduction rate were 89.62%,99.39% and 97.78% at the 7 th ,30 th, and 60 th day, respectively. Conclusion：The killing rate of Dulidao plastic bait was high and it could last for a long time. It was no pollution to the environment, worth to be widely applied.
