摘要:

目的 了解甘肃省铁路辖区德国小蠊对乙酰甲胺磷、残杀威、三氟氯氰菊酯、高效氯氰菊酯、氟虫腈5种杀虫剂的敏感性和致死效果。方法 采用WHO推荐的果酱瓶药膜接触法。结果 兰州、嘉峪关铁路辖区野生种群对高效氯氰菊酯抗性系数分别为2.17、12.34倍,对三氟氯氰菊酯抗性系数分别为2.87、4.96倍。三氟氯氰菊酯对兰州铁路地区野生种群致死效果下降率达90.00%,其次是残杀威(53.33%);残杀威、三氟氯氰菊酯对嘉峪关铁路地区野生种群致死效果下降率均为40.00%。结论 在对德国小蠊防治工作中应减少对高效氯氰菊酯、三氟氯氰菊酯的使用量,慎用残杀威,优先考虑使用乙酰甲胺磷、氟虫腈,有计划地交替、轮换使用杀虫剂。

Abstract:

Objective To identify the sensibility and lethal effect of Blattella germanica on acephate, propoxur, cyhalothrin, beta-cypermethrin and fipronil in the railway region of Gansu province. Methods The pesticide smeared jam bottle drug membrane contact method advocated by WHO was used in this study. Results The resistance coefficients of B. germanica from Lanzhou and Jiayuguan railway region were 2.17 and 12.34 to beta-cypermethrin and 2.87 and 4.96 to clocythrin, respectively. The killing effects of clocythrin and propoxur on B. germanica from Lanzhou railway region were 90.00% and 53.33% , respectively, and 40.00% against those from the Jiayuguan railway region. Conclusion The usage amount of beta-cypermethrin and clocythrin should be reduced and care given to the usage of propoxur. Priority should be given to the usage of acephate and fipronil alternately so as to delay and reduce the resistance among cockroaches.
