摘要
进行了无公害灭鼠剂克鼠星对中华鼢鼠的杀灭率、适口性及大田防治成本试验。结果表明,在室内试验中,克鼠星对中华鼢鼠的杀灭率为100%,大田试验中,防治率在83.7%~92.3%,其中春季和秋季防治率可达91.4%;克鼠星对中华鼢鼠的适口性极好,摄食系数为0.88~1.03。采用切封洞法防治用药量少,防治费用最低,投药有效率为70.0%~92.0%,比插洞法高40%以上;春季投药有效率最高,春季采用切封洞法投药较夏季投药有效率提高22.0%。
KRS,a new type of rodenticide with safety and non pollution,was studied to control Myospalax fontanierii (Chinese zokor).The results showed that the KRS showed a good palatability for Myospalax fontanierii .The intake coefficiency of Myospalax fontanierii to KRS was 0.88-1.03.The controlling effects of KRS for Myospalax fontanierii were 100.0% indoors and 83.7%-92.3% at planted forest site,and the controlling effects were better in spring and autumn than in summer.Three baiting methods,putting the bait into a hole bored on the top of zokors nets,putting the bait into a hole of zokors nets by transverse cutting the hole,and putting the bait into an effective hole by the hole cutting and blockage method,were also tested.The results indicated that the method of the hole cutting and blockage was the best in three,for it saved the bait,cost lowest and increased the validity of baiting to 70.0%-92.0%.It would be 22% more effective if baiting in spring than in summer.
