林业鼠害无公害防治技术及防治效果分析

Pollution-free Prevention and Control Technology and Control Effect of Forestry Rodents

通过采用银恒快速捕鼠器、新型环形捕鼠夹和“鼠道难”(20.02%地芬·硫酸钡)3种无公害技术对林业鼠害进行防治试验,结果表明:银恒快速捕鼠器射杀中华鼢鼠,触发率为34.89%,触发捕获率为99.52%;新型环形捕鼠夹防治大沙鼠、达乌尔黄鼠,发弓率为4.47%,捕获率为1.88%;“鼠道难”防治中华鼢鼠,使林木受害株率和死亡率分别下降5%和2%,防治大沙鼠和达乌尔黄鼠,效果明显,有效洞口较施药前下降72%以上。建议防治地下害鼠使用银恒快速捕鼠器,防治地上害鼠使用“鼠道难”,新型环形捕鼠夹适用于害鼠种类调查及监测。

The control of forestry rodents were conducted by using three kinds of pollution-free technologies:Yinheng fast mousetrap,new ring mousetrap and Diphenoxylate-Barium sulfate(20.02%diphenanthrene sulfate).Result shows that:The triggering rate and the trigger capture rate of Myospalax fontanierii by adopting Yinheng fast mousetrap is 34.89%&99.52%,respectively.The bowing rate and capture rate is 4.47%&1.88%respectively to prevent Rhombomys opimus&Citellus dauricus by adopting new ring mousetrap.Adopting Diphenoxy late Barium sulfate to control Myospalax fontanierii can reduce the rate and mortality of forest trees by 5%and 2%.Adopting Diphenoxy late Barium sulfate to control Rhombomys opimus and Citellus dauricus can obtain the obvious effect,and the effective hole is more than 72%lower than that before application.It is recommended to use the Yinheng fast mousetrap to control underground rodents,to use Diphenoxylate-Barium sulfate to control ground rodents.The new ring mousetraps are suitable for the investigation and monitoring of rodents.
