Abstract
The resistance ratios of adult mosquitoes of the Chianjen, Lingya (2002), and Lingya (1900R) strains for permethrin compared to susceptible strains were above 312.5X, while those of the 4th instar larvae were 20.8, 37.5, and 102.1, respectively. We used WHO insecticide-impregnated papers to determine the insecticide susceptibility of adult Aedes aegypti in 2002.. The Chianjen and Lingya (2002) strains showed resistance to cyfluthrin. The Chianjen, Lingya (2002), and Shinshing strains showed resistance to deltamethrin. The Chianjen, Lingya (1990R), Lingya (2002), Shinshing, Linyuan and Fengshan strains showed resistance to etofenprox. The Chianjen, Lingya (2002), Shinshing, Sanmin, Tzuoying, Linyuan, Gangshan, Fengshan, Gueiren, Shinshi, S. District, W. District, and C. District strains showed resistance to permethrin. The Sanmin, Tzuoying, and Gangshan strains showed resistance to lambdacyhalothrin. 2003, the Chianjen, Linya and Fengshan strains of Aedes aegypti were resistant to both etofenprox and permethrin, but the Chianjen and Lingya (2002) reduced resistance to cyfluthrin and deltamethrin. The Tainan South District strain of Aedes aegypti showed the resistant to permethrin and cyhalothrin. The Tainan Gueiren strain of Aedes aegypti showed the resistant to permethrin and cyhalothrin. Results of a synergism study on larvae resistant to permethrin showed correlations to the activities of microsomal monooxygenases and esterases.
The highest specific activities of esterase are 0.249
