为缓解鼠类的抗药性和减轻杀鼠剂的生态风险问题,笔者研究了每月定期布放鼠夹捕鼠后农田鼠密度的变化趋势及主要农作物的害鼠发生程度,探讨器械捕鼠防控害鼠的可行性。器械灭鼠后试验区的鼠密度消长趋势呈W形,与化学灭鼠后鼠密度的恢复动态相吻合;在水稻害鼠高峰期,器械捕鼠试验区的年均鼠密度控制在(3.54±0.86)%,早稻和晚稻的害鼠率分别为(0.36±0.02)%和(0.45±0.04)%,与杀鼠剂灭鼠的效果无显著差异。表明定期的持续捕杀能够显著降低鼠类的发生数量和农作物的害鼠程度。
In order to alleviate the resistance of mice and mitigate the ecological risks of rodenticides, the author studied the trend of the density changes of farmland mice after the regular placement of rattrap mice and the incidence of harmful crops in main crops. Control the feasibility of rats. The rodent densities showed a W-shaped trend in the experimental area after rodent exacerbation, which was consistent with the recovery of rat densities after rodenticideration. In the peak period of rodent infestation, the average annual rodent density of rodent tracts was (3.54 ± 0.86%). The rate of rodent infestation in early rice and late rice were (0.36 ± 0.02)% and (0.45 ± 0.04)%, respectively. There was no significant difference between rodent control and rodenticide rodent control. The results showed that regular sustained kill can significantly reduce the number of rodents and the degree of crop damage in rats.
