摘要
本文报告实验室选择性适口性试验结果,证实褐家鼠对杀它仗颗粒毒饵的接受性很好,摄食系数为1.17,试鼠死亡率为95%,试鼠均为出血而死,死亡期在给药后2～3天。在两个鼠密度高的现场灭鼠试验中,分别间隔限量投放0.05%杀它仗毒饵及饱和投放0.2%敌鼠钠盐毒饵,都取得一致的灭鼠效果;杀它仗试验区户均耗饵量48.7g,敌鼠钠盐试验区户均385.0g,前者可节省87%诱饵粮,且灭鼠效果、毒饵的接受程度和节省劳力等亦优于第一代抗凝血剂,值得推广应用。
It is show thatthe Stratagem Bait (WL-108366)is very palatable for Rattus norvigicus. The coefficient of intaking baits for them is 1.17, the rate of killing effect is 95%, under laboratory condition. The dea period of poisoning rats is about 2-8days after given poison Bait. All of them revealed hemorrhagic pathologic lesion by autopsy. In the their highest density period of time the test was conducted on interval and limited methcds given baits with 0.9% of stratagem bait, and with 0.2% of Diphacin-Na baits in the field, the result shown that both of them had achieved same killing effects. In the stratagem bait test aera the consumption of poison bait is 48.7g per household in average, and 385.0g per house-hold in average for Diphacin-Na.Therefore, the former is more economic and lesser dosage than the latter, or using the stratagem bait is more save on crops for bait.It is very priority to.Diphaciu-Na for controlling domestic Rodents
