不同毒饵盒内放置不同毒饵杀灭家栖鼠类效果比较观察

目的观察不同种类的毒饵盒内放置不同毒饵对家栖鼠类的杀灭效果。方法在临沂市兰山区选择环境条件相似的3个村庄,以木料、纤维板、水泥等为材料制作4种毒饵盒,内放0.05%敌鼠钠盐玉米、小麦及混合毒饵实施灭鼠,效果考核用S-100格法。结果用混合毒饵第10、45天时的灭效,单口梯形毒饵盒分别为66.90%和97.08%,单口长方形毒饵盒分别为73.11%和95.68%,木制三角形毒饵盒分别为83.00%和99.84%;单用玉米毒饵第10、20、30、60天时的灭效,水泥长方形毒饵盒分别为77.74%、88.82%、95.93%和98.97%,木制三角形毒饵盒分别为57.87%、89.67%、89.57%和95.35%;单用小麦毒饵第10、20、30、60天时的灭效,水泥长方形毒饵盒分别为75.02%、85.55%、94.43%和96.69%,木制三角形毒饵盒分别为43.26%、80.32%、88.07%和95.02%。结论预防性灭鼠应大力推广毒饵盒灭鼠法。

Comparison of the deratization Effect to rattus with different bait poisons in different bait poison boxes

Objective To observe the deratization effect with different bait poisons in different bait boxes at different periods of time. Methods On-the-spot test had been carried out with bait poisons in 3 rural areas of Lanshan district, Linyi city, which were in the same environmental conditions. Corn, wheat bait poisons of 0.05% diphacine-Na, and mixed bait poisons were put into 4 kinds of bait poison boxes which were made by wood, fibreboard and cement. S-100 method was used to evaluate the deratization effect. Results The deratization rate was as follows: the deratization rates with mixed bait poisons in trapezoidal boxes with one opening were 66.90% and 97.08%. But in rectangle boxes with one opening they were 73.11% and 95.68%, in wooden triangle boxes they were 83.00% and 99.84% on the 10th and the 45th day. The deratization rate with corn bait poison in rectangle cement boxes was 77.74%, 88.82%, 95.93% and 98.97% respectively, in wooden triangle boxes it was 57.87%, 89.67%, 89.57% and 95.35% respectively in the 10th, 20th, 30th and 60th day. The deratization rate with wheat bait poisons in rectangle cement boxes was 75.02%, 85.55%, 94.43% and 96.69% respectively, but in wooden triangle boxes it was 43.26%, 80.32%, 88.07% and 95.02% respectively on the 10th, 20th, 30th and 60th day. Conclusion The preventive deratization method with bait poison boxes must be spread.
