Abstract:Objective To understand the resistance levels and status of Aedes albopictus to commonly used insecticides,deltamethrin,permethrin,beta-cypermethrin,temephos and propoxur in Jiangmen City,and provide scientific evidence for selecting insecticides reasonably and controlling Aedes albopictus.Methods Larvae of Aedes albopictus were collected from six streets in Jiangmen City,and bred for 1-3 generations.The dipping method recommended by WHO was conducted in the bioassay.Results The larvae of Aedes albopictus collected from monitor sites were sensitive to temephos with the resistance under three folds.They were sensitive to propoxur except Didong population.The mosqtuioes collected developed different levels of resistance to beta-cypermethrin,deltamethrin and permethrin.There was significant difference of resistance among five insecticides (x2 =73.43,P<0.05),and among the six streets (x2 =40.44,P< 0.05).Conclusion Aedes albopictus develops different resistance to beta-cypermethrin,deltamethrin and permethrin.Insecticides should be applied scientifically and rationally.It is necessary to strengthen the surveilance of resistance and understand the development of resistance.
