达乌尔鼠兔的危害及其药物防治

Damage by Ochotona dauricaand and the Chemical Control

通过笼养观察、田间调查和试验分析,对林地达乌尔鼠兔主要生活习性和危害特点进行了观察,并对目前国内常用的防治害鼠效果比较理想的化学药剂毒鼠磷、溴敌隆、磷化锌和自制的初试产品克鼠星(KRS)进行对比试验,结果表明,不同药剂对防效有显著影响;4种药剂中以克鼠星对达乌尔鼠兔的杀灭效果最好,灭鼠率为87.39％,溴敌隆小麦毒饵和毒鼠磷小麦毒饵次之,磷化锌洋芋毒饵最差,其杀灭效果分别为77.32％、70.41％和65.99％。KRS最佳投饵量为5 g;对鲜豆角、洋芋、小麦 3种饵料进行筛选表明,不同饵料配成的毒饵,杀灭效果差异不显著;药物对达乌尔鼠兔的防治效果与投饵季节无关。

Based on cage observation, field investigation and experimental aralysis, habit and damage of Ochotona daurica were studied. Meanwhich, control experiments were done on the effects of four types of rodenticides including phosacetim, bromodiolone, zinphos and KRS. The results showed that the effect of KRS was the best, up to 87. 39% , bromodiolone with wheat 77. 32% , phosacetim with wheat 70. 41% and zinphos with potato 65. 99%. The optimal baiting dose was 5 grams. There were no significant differences among the baits of fresh bean, potato and wheat when the control effects were tested. And the effects were not related to the date of baiting.
