摘要
目的 :探讨外环境灭鼠投毒技术与方法 ,为全市外环境灭鼠提供对策。方法 :在居民区、停待建工地、农贸市场外环境用拖食法观察鼠对不同投毒方式、不同投毒容器间、同一容器内不同饵料间的拖食情况。结果 :在 3种外环境中 ,3种投毒方式 (容器、裸投、小包装 )拖食率差异有非常显著性 ( χ2 =2 73.39,P <0 .0 1) ,容器拖食率介于裸投和小包装之间 ;以容器而言 ,竹筒拖食率高于塑料盒 ( χ2 =7.43,P <0 .0 1) ,与砖砌毒饵站差异无统计意义 ( χ2 =0 .82 ,P >0 .0 5 )。从短期观察看 ,容器内放置颗粒和谷物类毒饵灭鼠效果优于腊块 ;从 30d连续观察看 ,腊块和小包装毒饵在南方潮湿外环境中 ,具有其他毒饵不可替代的作用。结论 :外环境灭鼠投毒应采用毒饵站 (容器投放 )和腊块、小包装等多种形式 ,因地制宜 ,科学应用。
Objective: To study the rodent control technology and methods in the outer environments of the city, Shanghai. Methods: Using bait expending in the our environments (residence area, food market, discard construction site) to observe the result (rate of bait expending) which the bait put in vary container, which the bait put in container and in out-container and which the vary bait (grain, cereal, wax) put in the same container. Result:The rate bait expending of three way (put bait in container, put the packing bait in ground and put the no-packing bait in ground) has difference (χ 2= 273.39, P< 0.01). The rate bait expending of the bait in container is situated between put the peaking bait and no-peaking bait in the ground.The rate bait expending on bamboo container higher than plastics container (χ 2= 7.43, P< 0.01), but it was not difference with brick container (χ 2= 0.82,P> 0.05). The result of cereal bait and grain bait put in the container is excellence than wax bait from short time. The wax bait and small packing bait were good methods in moist building-out for long time. Conclusion: The rodent control in the outer environments should be using bait box (bait station) and wax, small pecking bait.
