摘　　要：蓟马对农作物的危害逐年加重,为筛选防治蓟马的高效低毒药剂,采用叶管药膜法测定了10种常用药剂对4种蓟马的室内毒力,并开展了田间防效试验。室内毒力测定结果表明,6%乙基多杀菌素SC和10%虫螨腈SC对4种蓟马的毒力相对较高,25%噻虫嗪WG和5%甲维盐EC的毒力较低,西花蓟马和瓜蓟马对10种药剂的敏感性低于花蓟马和烟蓟马。田间药效结果表明,25%噻虫嗪WG、10%溴虫氟苯双酰胺SC和4.5%高效氯氰菊酯EC对西花蓟马的防效较高,药后7 d药效最高达到90%以上。综合室内毒力和田间药效试验结果,推荐4.5%高效氯氰菊酯EC和10%溴虫氟苯双酰胺SC为防治蓟马的首选药剂,可与25%噻虫嗪WG、48%多杀霉素SC、1.8%阿维菌素EC和10%吡丙醚SC等药剂轮换使用。The crop damage caused by thrips is increasing year after year.Thrips are important agricultural pests.In order to select insecticide with high-efficacy,the toxicity of 10 insecticides against four thrips was determined by leaf-tube membrane method,and the field trial to Frankliniella occidentalis was carried out.Laboratory bioassay showed that spinetoram 6%SC and broflanilide 10%SC had relatively high toxicity against four thrips,while thiamethoxam^(2)5%WG and emamectin benzoate 5%EC had low toxicity.The susceptibility of F.occidentalis and Thrips palmi to the 10 insecticides was lower than those of F.intonsa and T.tabaci.Field trial demonstrated that thiamethoxam^(2)5%WG,broflanilide 10%SC and beta-cypermethrin 4.5%EC had higher control effects on F.occidentalis,and the highest efficacy reached more than 90%7 d after application.Based on the laboratory and field results,beta-cypermethrin 4.5%EC and broflanilide 10%SC were recommended as preferred insecticides for thrips control,and thiamethoxam^(2)5%WG,spinosad 48%SC,abamectin 1.8%EC and pyriproxyfen 10%SC could be used alternately.
