摘　　要：为探索高效防治黄花菜蓟马的有效药剂,开展了7种杀虫剂防治黄花菜蓟马的田间药效试验。结果表明:7种杀虫剂对黄花菜蓟马均表现出较好的防治效果,且其田间防效呈先增强后逐渐减弱的动态变化趋势,其中,30%多杀霉素·噻虫嗪悬浮剂的速效性和持效期最好,喷药后1~3 d的防效达>90%,药后7 d的防效仍>70%。可见,多杀霉素和噻虫嗪复配制剂宜作为防治黄花菜蓟马的首选药剂。同时,为减缓蓟马抗药性的发展速度,建议将呋虫胺、溴氰虫酰胺、溴虫氟苯双酰胺、唑虫酰胺、虫螨腈·唑虫酰胺以及金龟子绿僵菌这6种药剂作为交替使用的药剂用于黄花菜田花蓟马的有效防控,确保黄花菜持续健康生长和产量稳定。A field efficacy trial was conducted to investigate the efficacy of seven insecticides for controlling fFrankliniella intonsa(Trybomin)Hemerocallis citrina Baroni.The results indicated that all insecticides demonstrated notable control effects,with efficacies peaking initially and then gradually declining over time.The 30%spinosad·thiamethoxam suspension concentrate(SC)exhibited the best quick-acting and long-lasting performance,achieving over 90%control efficacy within 1~3 days post-application and maintaining efficacy above 70%efficacy seven days after treatment.Based on the findings,the combined formulation of spinosad and thiamethoxam was recommended as the preferred option for controlling Frankliniella intonsa(Trybom)in Hemerocallis citrina Baroni.To prevent the development of pesticide resistance in Frankliniella intonsa(Trybom),the study also recommended the use of other pesticides,including dinotefuran,cyantraniliprole,bromofluramide,tolfenpyrad,chlorfenapyr·tolfenpyrad,and Metarhizium anisopliae,to ensure effective control of Frankliniella intonsa(Trybom)in Hemerocallis citrina Baroni and promoting the continuous healthy growth and stable yields of Hemerocallis citrina Baroni.
