摘要: 目的 了解百色市强化灭蚤地区印鼠客蚤对拟除虫菊酯类杀虫剂的抗药性情况。方法 采用药膜法测定蚤类抗药性,采用SPSS13.0软件计算杀虫剂的LC50及95%可信区间。结果 与对照地区(右江区)比较,强化灭蚤地区〔隆林各族自治县(隆林县)、西林县〕的印鼠客蚤对溴氰菊酯、高效氯氟氰菊酯、氯氰菊酯3种拟除虫菊酯类杀虫剂的敏感性明显下降,LC50明显增加;隆林县印鼠客蚤对3种拟除虫菊酯类杀虫剂的相对抗性倍数分别为6.22、7.69、5.69倍,西林县分别为5.29、6.03和4.82倍。结论 强化灭蚤地区印鼠客蚤已对拟除虫菊酯类杀虫剂产生抗性,应加强杀虫剂抗药性监测,科学合理用药。

Abstract: Objective To investigate the drug resistance of Xenopsylla cheopis to pyrethroids in the area of intensified flea control in Baise, Guangxi Zhuang Autonomous Region, China. Methods The insecticide resistance of X. cheopis was determined by residual film. The LC50 and 95% confidence interval of insecticide were calculated by SPSS 13.0 software. Results Compared with the control area (Youjiang district), fleas in the intensified control area (i.e., Longlin county and Xilin county) showed significantly decreased sensitivity to pyrethroids such as deltamethrin, beta-cyhalothrin, and cypermethrin as the LC50 of these insecticides increased susceptibility. The relative resistance ratios of X. cheopis to the three pyrethroid insecticides were 6.22, 7.69, and 5.69, respectively, in Longlin county, while those were 5.29, 6.03, and 4.82, respectively, in Xilin county. Conclusion Fleas in the intensified flea control area showed increasing resistance to pyrethroids. Therefore, surveillance of insecticide resistance should be highlighted for rational use of insecticides.
