摘要:

目的 了解海南省原登革热流行区埃及伊蚊和白纹伊蚊对常用杀虫剂的敏感性。方法 采用幼虫浸渍法,测定蚊虫对常用杀虫剂的抗性系数。结果 埃及伊蚊对溴氰菊酯抗性系数为2.04~2.82,而三亚市埃及伊蚊对高效氯氰菊酯的抗性系数为3.76。白纹伊蚊对溴氰菊酯的抗性系数为2.40~3.60,而海口市白纹伊蚊对仲丁威和残杀威抗性系数分别为2.63和2.07。结论 海南省原登革热流行区埃及伊蚊和白纹伊蚊对供试杀虫剂敏感性下降。

Abstract:

Objective To determine the susceptibility of Aedes aegypti and Ae. albopictus to commonly used insecticides in the previously Dengue fever?prevalent areas in Hainan province. Methods The larvae dipping method was used to measure the susceptibility of mosquitoes to commonly used insecticides. Results The resistance ratio of Ae. aegypti to deltamethrin was 2.04-2.82, and 3.76 to Beta cypermethrin in Sanya. The resistance ratio of Ae. albopictus to deltamethrin was 2.40-3.60, and 2.63 and 2.07 to fenobucarb and propoxur, respectively, in Haikou. Conclusion Decreased susceptibility of Ae. aegypti and Ae. albopictus to the sample insecticides was observed in the previously Dengue fever?prevalent areas in Hainan.
