投放1.5%甘氟毒饵后7天,再用0.01%氯鼠酮毒饵防治农田黑线姬鼠,灭效达100%,高于两者单独使用的效果(单用甘氟的灭效为91.87%),但15天后鼠密度回升0.13个百分点(单用氯鼠酮的灭效为89.3%)。交替使用急、慢性杀鼠剂,不仅能提高防治效果,还能延缓抗凝血杀鼠剂抗性鼠的出现。 7 days after the release of 1.5% Ganfang bait, and then with 0.01% Clofilin bait to prevent and cure Agaricus blazei, the killing effect reached 100%, which was higher than that of the two alone (the killing effect of Ganflu alone was 91.87% ), But the rat density recovered by 0.13% after 15 days (89.3% killing with chloroketone alone). Alternate use of acute and chronic rodenticides, can not only improve the control effect, but also delay the emergence of anticoagulant rodenticide resistant mice.
