电子驱鼠器在养殖场使用效果观察

Efficacy of using electronic mouse expeller on the farm

目的对电子驱鼠器的驱鼠效果进行观察评价。方法在某养殖场内选择鼠类经常活动的场所,每100m2放置驱鼠器一个,采用粉剂法测定实验前后的鼠密度变化并进行驱鼠率、回升率比较。结果驱鼠前测定平均鼠密度为59%,放置驱鼠器后第3天、第1、2周的鼠密度为30%、18%和17%,驱鼠率分别为49.2%、69.5%、71.2%。撤走驱鼠器后第3天、第1、2周鼠密度分别为8%、37%、53%,回升较为迅速。结论电子驱鼠器具有一定的驱鼠作用,随着使用时间的延长驱鼠的作用亦增强,但仍需长期使用才能有更好的效果,并需要注意使用方法、根据防治面积适当增加电子驱鼠器的数量和密度。

Objective To observe and assess the efficacy of using the electronic mouse expeller. Methods selecting some places which the mice live frequently, put mouse expellers every 100m^3; using pulvis method to determine the change of mouse density before and after the experiment; comparing the expelling mouse rate with the mouse recovery rate. Results Before the experiment, the average mouse density was 59%. The expelling mouse rate are 49.2%. 69. 5%. 71.2% for 3 days. 1 week. 2 weeks respectively. After taking away the mouse expellers for 3 days. 1 weeks . 2 weeks , the mouse density were 8%. 37%. 53% , it recovered rapidly. Conclusion The mouse expellers had definite effects and the effects were strengthened along with the using time. But it must be used for a long time , and we must pay attentin to the use method , increase the quantity properly according to the area of preventon and cure.
