Objective To investigate the current insecticide resistance status of dengue vector Aedes albopictus to commonly used insecticides in Mianyang city, so as to provide a basis for the rational use of insecticides. Methods The larvae dipping method was used to measure the insecticide resistance of the mosquitoes to commonly used insecticides. Results The resistance ratios of Ae. albopictus was 46.04-fold to deltamethrin, 45.18-fold to beta-cypermethrin, 249.60-fold to topermethrin for the highest, 2.44-fold to temephos, and 2.32-fold to DDVP for the lowest. Conclusion Aedes albopictus showed high resistance to pyrethroid insecticides, but low resistance to organophosphorus insecticides. Insecticides should be used strategically to hinder the development of insecticides resistance.
Key words： Aedes albopictus; Resistance coefficient; Insecticides
