摘　　要：田间试验结果表明，吡虫啉具有对稻虱击倒力强、持效期长、防效高而对天敌安全的特点。在稻虱低龄若虫高峰期，亩用吡虫啉１０～３０克，药后２天防效达９２．４～１００％，而噻嗪酮仅为４７．７％。药后３２天调查，吡虫啉对稻虱仍保持很高防效且对蜘蛛杀伤率低。在亩用１０～２０克防治稻虱适宜剂量下，可混配杀虫单每亩３０～３５克，以兼治稻纵卷叶螟。The result of field trial showed that with high knock-down and persistence effect,imidacloprid was exellent active against rice plant hopper(Liburnia sordescens)and safe to natural enemy. The control effect of the test reached 92.4￣100% after 2 days of using imidacloprid in the peak stage of young nymphs at the dosage of 150￣450 g/ha,and the effect was sustained for 35 days.Whereas the knock-down effect of buprofezin was only 47.7%.The mixture of imidacloprid (150￣ 300 g/ha)and Shachongdan (450￣525 g/ha) can control L.sordescens as well as rice leaf roller (Cnaphalororis medinalis).
