摘要

目的了解武汉市德国小蠊对5种杀虫剂的抗性状况,为科学使用杀虫剂提供依据。方法采用WHO推荐的药膜法,测定经实验室饲养1代的试虫对常用杀虫剂的半数击倒时间(KT₅₀)及其95%可信区间(95%CI)、击倒率和死亡率,评价其对抗药性的程度。结果汉口、汉阳和武昌3个镇的德国小蠊对残杀威、毒死蜱、高效氯氰菊酯和甲基吡恶磷的抗性分别是敏感品系的1.4~2.2、1.5~1.7、2.8~3.1和2.5~2.9倍,对胺菊酯的抗性极高,超过了可测范围。结论在灭蜚蠊工作中应采取综合性防治措施,科学合理使用杀虫剂。

Abstract

Objective To investigate the resistance of Blattella germanica against five insecticides and customize future application of insecticides.Methods The B. germanica used in this study were the first filial generation (F1 generation 1). The insecticide film method recommended by the World Health Organization was used to determine the median knock-down time (KT₅₀) and the corresponding 95% confidence interval (95%CI), knock-down rate, and mortality rate of B. germanica exposed to the five commonly used insecticides and to assess the levels of resistance of B. germanica. Results The average resistance of B. germanica strains from Hankou, Hanyang and Wuchang against propoxur, ehlorpyrifos, betacypermethri and azamethiphos was 1.4-2.2, 1.5-1.7, 2.8-3.1, 2.5-2.9 fold. Its resistance against tetramethrin was beyond the test range. Conclusion It was advised to apply integrated control measures and use insecticides strategically in controlling B. germanica.
