摘要: 目的:解决灭鼠毒饵久藏后被储粮害虫侵袭问题。方法:用溴氰菊酯杀虫剂配制防虫毒饵,进行防虫效果、适口性和现场灭鼠效果试验。结果:1ppm、2ppm溴氰菊酯对基饵在12个月内的保护率均为100%。实验室内大白鼠对1ppm、2ppm溴氰菊酯玉米和小麦混合基饵的摄食系数分别为0.93和0.80,且对鼠无毒;现场(食品行业和居民区)试验1ppm溴氰菊酯基饵摄食系数在0.96以上。现场应用5/万敌鼠钠盐普通毒饵与防虫毒饵,灭鼠率分别为91.29%、88.69%。经统计学检验,两者差异不显著。结论:所试毒饵防虫效果颇佳,鼠的摄食率高,不影响药物灭鼠效果,值得深入研究。

Abstract: 1 ppm and 2ppm NRDC161 can protect grain bait 100 percent from harmful insects for 12 monthes indoor. The breeding index of white rat for 1 ppm and 2 ppm NRDC161 maize and wheat bait were 0.93 and 0.8 in laboratory and it was not toxicity for rats. The breeding index which 1ppm NRDC161 grain bait to be eaten by rats was more than 0.96 in line of food and residence area. 5/10 000 Diphacine-Na ordinary poison bait and anti-insect poison bait were used to kill rats in spot. The deratization rates were 91.29 percent and 88.69 percent. There isn't differece between the former and the latter by statistic test.
