摘要: 目的:研究蚊虫对拟除虫菊酯抗性的发生发展规律,深入探讨抗性机理。方法:在实验室条件下,对淡色库蚊敏感品系用二氯苯醚菊酯丙酮液筛选,连续筛选20代。结果:成功地选育出淡色库蚊实验室抗性品系,现抗性倍数保持在70倍左右。结论:该抗性品系的种群生存力明显降低,表现为用药后卵孵化率、化蛹率、羽化率和成成蚊率比正常的敏感品系要低。

Abstract: To study the mechanism of mosquito pyrethroid resistance, in laboratory with immersion, a permethrin-resistant strain of Cular pipiens pallens was seleced.After 2O generations,it attained a stable level of 70-foId permethrin resistance.In the meanwhile it was found that itS exiStant abiIity decreased.
