Abstract:
Objective To observe and evaluate the palatability and efficacy of α-chlorohydrin rodenticides that causes sterility in male rats in laboratory and the field. Methods (1) Male adult rats without offspring were fed with 1% α-chlorohydrin wheat baits as the experimental group whilst the control group was fed with normal rat feed. Male and female rats were caged for two weeks in prior to dissection of the females to determine the number of fetuses. (2) The powder trace method was applied to measure the rat density for evaluating the field efficacy of rodent control. Results With an average coefficient of intake of 0.221, this male sterility?inducing 1% α-chlorohydrin baits caused an averagely 70.7% to 100% reductions of rat fetuses. The on?site rodent control rate reached 84.09%. Conclusion In addition to remarkable efficacy of rodent control in a laboratory setting, this rodenticide had obvious on?site rodent control effects. However, further improvements of the palatability of wheat?based male?sterilization 1% α-chlorohydrin baits are desired.

摘要:
目的 通过实验室和现场试验,分别观察评价雄性不育灭鼠剂α-氯代醇的适口性和灭鼠效果。方法 (1)取成年未孕大白鼠为试验对象,用1% α-氯代醇小麦饵料喂养雄鼠,同时设立对照组,用普通鼠料喂养。雌雄动物合笼饲养2周,然后解剖检查雌鼠孕胎数。(2)通过用粉迹法观测鼠密度,评价现场灭鼠效果。结果 1% α-氯代醇雄性不育饵剂平均摄食系数为0.221,胎鼠平均减少率达到70.7%~100%,现场灭鼠率为84.09%。 结论 以小麦为基饵的1% α-氯代醇雄性不育饵剂适口性需通过改善饵剂进一步提高;实验室灭鼠效果显著,现场灭鼠也有较为明显的效果。
