Abstract:Objective To understand the resistance of Aedes albopictus (Ae. albopictus), Musca domestica (M. domestica) and Blattella germanica (B. germanica) to several commonly used insecticides in Taizhou city, and to provide a basis for the choice of insecticides. Methods The insecticide resistance levels of Ae. albopictus, M. domestica and B. germanica were tested by using exposure tubes method, topical application method and insecticide film method respectively. Results The mortality rate of adult Ae. albopictus after 24 hours of exposure to deltamethrin, beta-cypermethrin, permethrin, propoxur and malathion paper were all 100%. The resistance ratios of M. domestica to propoxur, dichlorvos, beta-cypermethrin, deltamethrin and permethrin were > 372.40, 5.70, 155.21, 66.87 and 10.94, respectively. The resistance ratios of B. germanica to propoxur, dichlorvos, beta-cypermethrin, deltamethrin and acephate were 1.05, 0.87, 1.30, 2.67 and 1.42, respectively. Conclusions Adults of Ae. albopictus in Taizhou city were sensitive to five kinds of insecticides tested. M. domestica was resistant to five kinds of insecticides, of which propoxur was no longer effective. B. germanica showed low resistance to the tested pesticides.
