9 种药剂对芹菜蚜的毒力测定及田间药效评价

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。

Toxicity Determination of Nine Insecticides against Semiaphis heraclei and Evaluation of Field Control Efficacy

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．
