摘要：
毒饵站是化学防鼠常用设施,可以减少非靶标动物的误食风险.目前常用毒饵站容量小、毒饵易浪费、添加毒饵不便的缺点限制了其在东北地区的大规模应用.本研究针对东北农业环境特点,设计了一种新型高置式大容量毒饵站,在黑龙江了进行为期1年的防效试验,并测试其作用范围.结果表明,这种毒饵站每年毒饵用量2.8～3.8 kg,鼠密度控制率可长期保持在75％以下;其有效覆盖面积为1.1 hm2,最佳防治效果的覆盖面积为0.5 hm2.这些结果说明这种大容量高置式毒饵站具有毒饵添加便捷、无浪费的优点,在东北地区防治经济效益远远大于其他传统小容量毒饵站,值得在当地应用和推广.%Poison station is commonly used in management of rodent pest and can effectively decrease the risks of mistaken eating by non-target animals.Aim at possible application against rodent pests in farmlands of northeast China,commercialized poison stations common show some disadvantages limiting their utilization around this area,such as the light weight,small size,poison bait wasting,and inconvenience for bait replenishment.According to agriculture traits in northeast China,we designed a new-type high-capacity poison station and tested its control efficacy and effective range in farmlands during one year.The results showed that the consumption of each poison bait station was from 2.8 to 3.8 kg and control efficacy was over 75％.Its effective range was up to about 1.1 hm2,and the best range was in 0.5 hm2.The advantages of this new-type high-capacity poison station,such as convenience to adding baits,no waste,higher economic value,extremely facilitate its application and promotion in northeast China.
