摘　　要：为比较不同杀虫剂对水稻褐飞虱的防治效果和持效期,以及对水稻安全性的影响,开展了田间药效对比试验。结果表明,20%三氟苯嘧啶水分散粒剂、10%异唑虫嘧啶悬浮剂、50%烯啶虫胺可溶粒剂和22%氟啶虫胺腈悬浮剂对褐飞虱的防治效果较好,对水稻生长相对安全,尤以20%三氟苯嘧啶水分散粒剂135 g/hm^(2)对褐飞虱防治效果好、药效期长,施药后14 d防效仍在92%以上。水稻生产上建议用20%三氟苯嘧啶水分散粒剂135 g/hm^(2)、10%异唑虫嘧啶悬浮剂300 g/hm^(2)、50%烯啶虫胺可溶粒剂150 g/hm^(2)以及22%氟啶虫胺腈悬浮剂600 g/hm^(2)交替、轮换施药。To compare the control effects and residual efficacy of different insecticides on Nilaparvata lugens in rice,as well as its safety to rice,a field efficacy comparison trial was conducted.The results showed that 20% Triflumezopyrim water-dispersible granules,10% Yizuochongmiding suspension,50% Nitenpyram soluble granules,and 22% Sulfoxaflor suspension had good control effects on Nilaparvata lugens and were relativly safe for rice growth.In particular,20% Triflumezopyrim water-dispersible granules at 135 g/hm^(2) had a good control effect on Nilaparvata lugens and a long residual effect,with an efficacy of over 92% still maintained 14 days after application.It was recommended to use 20% Triflumezopyrim water-dispersible granules at 135 g/hm^(2),10% Yizuochongmiding suspension at 300 g/hm^(2),50% Nitenpyram soluble granules at 150 g/hm^(2),and 22% Sulfoxaflor suspension at 600 g/hm^(2) in rice production,alternating and rotating their application.
