目的观察0.05%敌鼠钠蜡皮颗粒毒饵及蜡皮颗粒混合毒饵现场对褐家鼠和小家鼠的杀灭效果。方法选择济南市张马村居民居住比较集中的住宅共760间房间(每个房间约为15m2)。其中,放置蜡皮颗粒混合毒饵组为249间房间,蜡皮玉米颗粒毒饵组为267间房间,蜡皮小麦颗粒毒饵组为244间房间;在每房间内布放蜡皮毒饵3堆,每堆10g。连放4d,观察26d。灭效考核用格粉板法(400格法)。结果蜡皮颗粒混合毒饵和蜡皮玉米颗粒毒饵对褐家鼠的灭效分别为97.45%和92.44%,二者比较差异有统计学意义(u=5.22,P<0.01);对小家鼠的灭效分别为100%和99.47%,二者比较差异无统计学意义(u=1.46,P>0.05)。蜡皮颗粒混合毒饵与蜡皮小麦颗粒毒饵对褐家鼠的灭效分别为97.45%和96.59%,二者比较差异无统计学意义(u=1.19,P>0.05);对小家鼠的灭效均为100%。结论蜡皮毒饵对褐家鼠和小家鼠的杀灭效果均很好。且蜡皮玉米颗粒毒饵7份与蜡皮小麦颗粒毒饵3份混合使用杀灭褐家鼠要比单独使用蜡皮玉米颗粒毒饵效果好。
Objective To observe the killing effect of 0.05% rimsodium sphingosine bait and wax skin bait mixed bait on Rattus norvegicus and Mus musculus. Methods The residents of Zhangma Village, Jinan City, selected a total of 760 rooms (each room is about 15m2). Among them, there were 249 rooms in which the wax bait group was placed, that in the wax bait corn group bait group was 267 rooms, and the wax skin wheat bait group was 244 rooms. Three batches of wax skin bait were placed in each room, 10g. Even put 4d, observe 26d. Out of effect test with the grid plate method (400 grid method). Results The results showed that the killing effect of the wax bait and the wax bait corn bait were respectively 97.45% and 92.44%, the difference was statistically significant (u = 5.22, P <0.01) The killing effects were 100% and 99.47%, respectively, with no significant difference (u = 1.46, P> 0.05). The curative effects of wax skin pellet mixed baits and wax skin wheat pellets on browning rats were 97.45% and 96.59%, respectively, with no significant difference (u = 1.19, P> 0.05) Effective are 100%. Conclusion The wax bait bait on the brown house mouse and Mus musculus killing effect are good. And wax skin corn particles bait 7 copies and wax skin wheat particles bait 3 mixed use to kill brown rat than single wax wax corn particles bait effect.
