【摘要】：目的观察蜡皮玉米粒7份、蜡皮小麦粒3份混合毒饵对褐家鼠和小家鼠的杀灭效果。方法选择济南历城区郭家、张马、贤文、靳家4个农村。郭家村有1 219间房,全部投放蜡皮混合毒饵;相距约500 m的靳家村有662间房,全部投放对照普通混合毒饵。选择张马村居民居住较集中的60户计498间房;在相距约3.5 km的贤文村选择60户计516间房。每村分为试验组与对照组。每间房间约15 m2放3堆,每堆10 g。连放4 d,观察26 d。灭效考核用格粉板法(400格法)。结果蜡皮混合毒饵与对照普通混合毒饵均做了3组试验,对褐家鼠的平均灭效分别为92.55%、94.97%,二者比较差异有统计学意义(u=8.41,P0.01);对小家鼠的平均灭效分别为99.82%、98.95%,二者比较差异无统计学意义(u=1.88,P0.05)。结论蜡皮混合毒饵对褐家鼠和小家鼠的灭效均很好,为灭鼠提供了一种优良毒饵。
[Abstract]:Aim to observe the killing effect of 7 samples of waxy corn grains and 3 parts of mixed poison bait on Rattus norvegicus and Meriones norvegicus. Methods Guojia, Zhang Ma, Xianwen and Jin villages in Licheng District of Jinan were selected. There were 1 219 rooms in Guo Jia Village and 662 rooms in Jin Jia Village about 500 m apart, all of which were put into the common mixed bait. A total of 498 houses were selected from 60 households living in Zhangma Village, and 516 houses were selected from Xianwen Village, which is about 3.5 km apart. Each village was divided into test group and control group. Each room is about 15 m2 with 3 stacks, each with 10 g. For 4 days, observe 26 d. Check the efficacy of the grid powder plate method (400 grid method). Results the average killing effect was 92.55% and 94.97% for Rattus norvegicus, respectively. There was a significant difference between the two groups (ux8.41, P0.01). The results showed that there was no significant difference between the two groups (u = 8.41, P 0.01), and the average killing effect was 92.55% and 94.97% for Rattus norvegicus. The average killing effect on mice was 99.82% and 98.95%, respectively. There was no significant difference between the two groups (ux1.88, P0.05). Conclusion the mixed baits of wax skin have good killing effect on both Rattus norvegicus and mice, and provide a kind of excellent bait for killing rodents.
