摘要
采用WHO生物测试法,测定了微山湖区韩庄镇淡色库蚊幼虫对常用杀虫剂的抗性水平。结果显示韩庄镇淡色库蚊幼虫对残杀威、DDVP、三氯杀虫酯、溴氰菊酯、氯氰菊酯等5种常用杀虫剂的LC50分别为0.4741、1.4012、0.2420、0.0034和0.0041mg·L-1,以菊酯类杀虫剂抗性最高。
Culex pipiens pallens was collected from the Weishan Lake district and its insecticidal resistance was measured using a standard WHO bioassay. Cx. pipiens pallens of Hanzhuang was resistant to five insecticides to some degree. The LC50 of Cx. pipiens pallens to propoxur, DDVP, aeetofenate, deltamethrin, and cypermethrin was 0. 474 1, 1. 401 2, 0. 242 0, 0. 003 4, and 0. 004 1 mg · L^- 1 , respectively. Cx. pipienspallens was most resistant to synthetic py- rethroid pesticides.
