Objective To investigate the resistance of adult Aedes albopictus to four hygienic insecticides in Nanchong, Sichuan, China, and to provide a scientific basis for prevention and control of Ae. albopictus. Methods From June to July the larvae of Ae. albopictus were collected from five districts (counties) in Nanchong and then underwent laboratory breeding for 1 to 2 generations; female mosquitoes that had not sucked blood for 3 to 5 days after emergence were selected and tested for insecticide resistance by exposure to a tube lined with insecticide-impregnated paper as recommended by the World Health Organization. Results After exposure to 0.4% beta-cypermethrin, 0.1% deltamethrin, 0.5% malathion, and 0.05% propoxur for 1 hour, the 24-hour mortality rates of adult Ae. albopictus were 61.49%-76.00%, 22.91%-53.74%, 88.00%-100%, and 95.24%-100%, respectively; the mosquitoes were resistant to beta-cypermethrin and deltamethrin, and were sensitive or suspiciously resistant to malathion and propoxur. Conclusion Adult Ae. albopictus in Nanchong, Sichuan have developed resistance to beta-cypermethrin and deltamethrin, and remain relatively sensitive to malathion and propoxur. Surveillance of the insecticide resistance of Ae. albopictus should be strengthened, and insecticides should be used scientifically and properly to prevent or delay the development of resistance.
