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.%采用室内浸叶法和大田试验法，测定了10%吡虫啉可湿性粉剂（WP）、10%烯啶虫胺水剂（AS）、1.8%阿维菌素乳油（EC）、10%溴氰虫酰胺悬浮剂（SC）、2.5%高效氯氟氰菊酯水乳剂（EW）、4.5%高效氯氰菊酯EC、0.3%苦参碱AS、240 g·L-1螺虫乙酯SC、25%噻虫嗪水分散粒剂（WG）等9种药剂对芹菜蚜的室内毒力和田间防治效果。室内生物测定结果表明：除螺虫乙酯外，噻虫嗪、烯啶虫胺、高效氯氟氰菊酯、苦参碱、吡虫啉、溴氰虫酰胺、高效氯氰菊酯和阿维菌素对芹菜蚜均有较高的毒力。田间药效试验结果表明：9种药剂对芹菜蚜均具有良好的防治效果，药后3 d和7 d的防效均高于98%，且均未对芹菜产生药害。
