Abstract :
The organophosphate, carbamate and pyrethroid resistance levels in 14 strains of Culex quinquefasciatus from Camagey were studied by bioassays and biochemical tests in larvae with or without synergists. The use of electrophoresis in polyacrylamide gel (PAGE) allowed to identify 8 patterns of esterases, among which A3A6B6, BiB6 and B1A6B6 were the most frequent. It was observed that 6 years after the suspension of malathion, there is still resistance to this product. There was also cross resistance to propoxur. Detoxification mechanisms for deltamethryn are being developed. The most important physiological mechanisms were: elevated esterases in the resistance to malathion, modified AchE for propoxur and oxidases of multiple function for deltamethryn. In relation to the genic frequencies, the modified AchE mechanisms was more extended than that of the elevated esterases in these populations of mosquitoes of the central region of Cuba. |
