Abstract：The toxicity and control efficacy of 9 insecticides，10% imidacloprid wettable powder
（WP），10% nitenpyram aqueous solutions（AS），1.8% abamectin emulsifiable concentrate（EC），10%
cyantraniliprole suspension concentrate（SC），2.5% lambda-cyhalothrin emulsion in water（EW），4.5%
beta-cypermethrin EC，0.3% matrine AS，240 g·L-1 spirotetramat SC and 25% thiamethoxam water
dispersible granual（WG）against Semiaphis heraclei were evaluated by using leaf-dipping method and field
trial methods． The indoor bioassay results showed that except for pirotetramat，thiamethoxam, nitenpyram，
lambda-cyhalothrin，matrine，imidacloprid，cyantraniliprole，beta-cypermethrin and abamectin had
higher toxicity on S． heraclei． The field trial efficacy of these 9 insecticides against S． heraclei was higher
than 98% 3 and 7 days after treatment without any phytotoxicity on celery．
