摘　　要： 5种复配药剂防治水稻稻纵卷叶螟的田间试验结果表明:17%阿维菌素·毒死蜱EC204～328.5ga.i./hm2处理保叶和杀虫效果最高,其次为21%氟虫腈·毒死蜱ME267.75～315ga.i./hm2和31.5%丙溴磷·氟虫腈EC189～236.25ga.i./hm2处理,再次为55%氟虫腈·杀虫安WG495～577.5ga.i./hm2和3.6%阿维菌素·氟虫腈ME18.9ga.i./hm2处理。5种复配药剂按以上推荐用量的保叶和杀虫效果均优于或相当于对照药剂1.8%阿维菌素EC8.1ga.i./hm2和5%氟虫腈SC30ga.i./hm2处理。 The field trials of five synergistic insecticides against Cnaphalocrocis medinalis were carded. The results showed that the effects of protective leaves and killing larva of abamectin and chlorpyrffos 17% EC at 204-328.5 g a.i./ha were the highest among five synergistic insecticides. The control effects of fipronil and chlorpyrifos 21% ME at 267.75-315 g a.i./ha and profenofos and fipronil 31.5% EC 189-236.25 g a.i./ha were higher than those of fipronil and profurite-aminium 55% WG at 495-577.5 g a.i./ha and abamectin and fipronil 3.6% ME at 18.9 g a.i./ha. All their effects applied at recommended dosage were similar to better than those of abamectin 1.8% EC at 8.1 g a.i./ha and fipmnil 5% SC at 30 g a.i./ha.
