新型灭蟑毒饵的研究

Studies on cockroach bait

目的 :为研究新型灭蟑毒饵对蟑螂的杀灭作用。方法 :采用四臂嗅觉仪从多种供试材料中筛选含有对德国小蠊有引诱作用的材料 ,并用这种材料与几种杀虫剂配成不同毒饵。结果 :动物饲料Ⅰ号对德国小蠊具有明显的引诱作用 ,且可以与其它不同杀虫剂混配 ,0 1%锐劲特混配毒饵对德国小蠊 4 8h死亡率可达10 0 % ,LD50 为 80 6 8± 2 5 1。结论 :0 1%锐劲特毒饵有很强的引诱毒杀作用 ,且群体杀灭较彻底 。

Objective:To study a new cockroach bait.Methods:Food attractants to Blattella germanica were screened using four arm olfactometer, and different baits which contained food attractants and pesticides were assessed in laboratory. Results:No.1 animal fodder has obvious attraction to the cockroach. 0 1% fipronil was of effective control result.The mortality reached 100% in 48 h.The LD 50 was 80 68±2 51 Conclusion:The bait, which consisted of 0 1% fipronil and No.1 animal fodder, has strong capability to attract and kill the cockroach. The population of Blattella germanica could be thoroughly destroyed and difficult to recover after using this mixture.
