Study on Efficacy of Compound High-effect Gel Bait against Cockroaches to Cockroach

[目的]测定复配高效灭蟑胶饵的防治效果。[方法]采用粘捕法进行现场蟑螂密度测定,现场施用复配高效灭蟑胶饵,观察施药前后蟑螂密度变化,评价杀灭效果。[结果]蟑螂种类均为德国小蠊,并且操作间中蟑螂密度最高。施用该灭蟑胶饵后,蟑螂平均在1.25 min就可以寻找到食物并且在6.50 min出现中毒现象,19.50 min后死亡;施药8 d后,灭杀率达80%以上;60 d后灭杀率达95%以上。[结论]该胶饵1次投药后对蟑螂有良好的杀灭效果,使用方便、安全,可推广应用。

[Objective] The aim of the research was to investigate cockroaches＇ density in hotel and observe the efficacy of compound high-effect gel bait against cockroaches.[Methods] Adhesive killing method was used to investigate cockroaches＇ density.The killing effect was assessed by observing the density change of cockroaches before and after the adhesive bait application.[Results] The cockroaches were all Blattella germanica and the main encroached places were kitchens.The time of cockroaches finding the gel bait,appearing poison symptom and killing was 1.25 minutes,6.5minutes and 19.5 minutes after using the gel bait,respectively.Eight days after using the gel bait,the mortality rate of cockroach was above 80%,and 60 days later,the mortality rate of cockroach was above 90%.[Conclusion] The compound high-effect gel bait against cockroaches that was convenient and safe for use.had remarkable effect on killing cockroaches at one time of the application,which was worth popularized.
