摘要
目的探讨11种蜚蠊毒饵对德国小蠊室内药效评估方法。方法每个烧杯放10只德国小蠊成虫,雌雄各半,放置饲料、水和灭蟑毒饵,每种毒饵重复3次,同时设空白对照;24h后取出毒饵,计算毒饵的失水率、取食量和毒饵对蜚蠊的致死中时间(LT50)。结果 11种蜚蠊毒饵在96h内都可杀死德国小蠊,达到了国标A级(GB/T13917.7-2009),但其LT50、失水率和取食量有很大差异。结论 11种蜚蠊毒饵均可有效杀灭德国小蠊,具体使用可根据需要和现场情况,综合评价选择最适合的蜚蠊毒饵。
Objective To evaluate the efficacy of 11 kinds of cockroach baits. Methods Ten adults of Blattella germanica （half male and half female） with feed, water and cockroach baits were put into a beaker. Three replications were made for each bait with blank control. Twenty-four hours later, the cockroach baits were taken out and the LT50, water loss rate and feeding amount were calculated. Results All of the eleven kinds of cockroach baits can kill B. gerrnanica within 96 hours, meeting grade A of national standards （GB/T 13917.7-2009）, but their LT50, water loss rate and feeding amount are quite different. Conclusion Eleven kinds of cockroach baits can effectively kill B. germanica. Comprehensive evaluation based on the needs and site conditions should be done to select the most suitable cockroach bait.
