目的观察在毒饵盒中投放急慢性毒饵灭家栖鼠类及对小家鼠和褐家鼠的灭鼠效果。方法选择济南市历城区西彩石村,每间房间布放毒饵盒1个,内放0.5%毒鼠磷和0.05%敌鼠钠整粒小麦。急性药剂毒饵盒放50g,慢性药剂毒饵盒放100g,每组90户;效果考核S100格法。结果急性药剂毒饵盒5、10、15、20d总灭鼠率分别为77.54%、82.36%、88.50%和93.78%;针对小家鼠灭效分别为76.81%、82.83%、88.92%和94.14%,褐家鼠灭效分别为100%、68.29%、75.61%和80.49%。慢性药剂毒饵盒10、20、30、60d总灭鼠率分别为90.93%、93.17%、98.11%和98.28%;针对小家鼠灭效分别为91.12%、93.24%、98.18%和98.24%,对褐家鼠灭效分别为80.95%、92.86%、95.24%和100%。慢性药剂毒饵盒第10天总灭鼠效果优于急性药剂毒饵盒(u=11.43,P<0.01)。结论慢性抗凝血灭鼠剂毒饵盒灭鼠效果显著。
Objective To observe the killing effects of acute and chronic poison bait on domestic rats and mice and Rattus norvegicus in the bait box. Methods Choi West Village, Licheng District, Jinan City, each room layout of a bait box, containing 0.5% poisonous rat phosphorus and 0.05% of the whole body of wheat against the enemy of sodium. Acute drug bait box put 50g, choleretic poison bait box put 100g, each group of 90; effect test S100 格法. Results The total extinction rates of the acute drug kit were 77.54%, 82.36%, 88.50% and 93.78%, respectively. The killing rates against the mice were 76.81%, 82.83%, 88.92% and 94.14%, respectively. Rattus norvegicus was 100%, 68.29%, 75.61% and 80.49%, respectively. The total rate of rodent exacerbation was 90.93%, 93.17%, 98.11% and 98.28% respectively for the 10, 20, 30, 60 days of the chronic drug bait box; 91.12%, 93.24%, 98.18% and 98.24% Rattus norvegicus kill 80.95%, 92.86%, 95.24% and 100%, respectively. The total exterminating effect of chronic drug bait box on day 10 was better than that of acute drug bait cassette (u = 11.43, P <0.01). Conclusion Chronic anticoagulant rodenticide bait box has significant anti-rat effect.
