Abstract:
Objective To investigate the type and consumption of sanitary insecticides used in Putuo District of Shanghai， determine the current resistance of Aedes albopictus to the insecticides， and explore the causes of regional variations in insecticide resistance spectrum. Methods Public and private institutions of pest control operation were investigated on the use of sanitary insecticides. Dipping method and tube method were used to measure the insecticide resistance of Aedes albopictus， including larvae and adults. Results The main insecticides used in residential areas and governmental units was β-cypermethrin， while that in markets and public environment was propoxur. In addition， and the insecticides in dengue control program was λ-cyhalothrin. Aedes albopictus larvae had medium resistance to parathion， and were sensitive to propoxur， with insignificant change within three years. Their resistance to permethrin and deltamethrin was medium and high， respectively. Moreover， resistance to β-cypermethrin increased over years. In contrast， resistance of adult Aedes albopictus differed by area， except consistently being sensitive to fenitrothion. Conclusion Multiple sanitary insecticides have been used in Putuo District. In addition， Aedes albopictus has different resistance to these insecticides by area. It suggests that resistance surveillance should be promoted， which may be crucial for scientific application of insecticides and impede the development of potential resistance.
