Indoor Toxicities of Ten Insecticides to Q-type Bemisia tabaci in Nanjing District

In order to scientifically apply insecticides to control Q-type Bemisia tabaci in the production in Nanjing,the toxicities of ten insecticides to Q-type Bemisia tabaci in Nanjing district were tested in the laboratory,and different determination methods were designed according to the morphology and instar of Bemisia tabaci.The results indicated that the toxicities of Abamectin,Emamectin benzoate,Acetamiprid and Azadirachtin to the adult and nymph were higher than those of the other insecticides tested in the experiments.Among the ten insecticides,only Azadirachtin and Thiacloprid exhibited high ovicidalactivity.Therefore,the application of the antibiotic insecticides with high sensitivity,the alternative use of the neonicotinoid pesticides,and the combined application of the insecticides with high ovicidalactivity were recommended in the control of Bemisia tabaci in Nanjing district.
