Abstract:Objective In order to provide a basis for scientific and reasonable use of pesticides, we investigated the resistance of Aedes albopictus to commonly used insecticides in urban area of Shaoguan city. Methods WHO standard bioassay method was applied to calculate LC50 and to obtain resistance index by comparing with susceptible strains. Results The median lethal concentration of Ae. albopictus to beta-cypermethrin, decamethrin, dichlorvos, propoxur are 0.0036, 0.0060, 0.2606, 2.1266 mg/L respectively. The resistance index are 3.60, 2.73, 1.53, 1.24 respectively. Conclusion Aedes albopictus in urban area of Shaoguan had low level resistance to beta-cypermethrin and decamethrin. It is important to alternate pesticides and choose appropriate doses in mosquito prevention and control.
