摘　　要：以水稻品种盐丰47为材料,研究了3%甲氨基阿维菌素苯甲酸盐水乳剂、40%毒死蜱乳油、40%丙溴磷乳油和80%杀虫单可溶性粉剂4种杀虫剂不同浓度处理对稻纵卷叶螟的田间防治效果。结果表明:4种供试杀虫剂的速效性和持效性均较好,对水稻稻纵卷叶螟具有较好的防治效果。施药后10 d,3%甲氨基阿维菌素苯甲酸盐水乳剂9、12和15 g/hm2,40%毒死蜱乳油470和520 g/hm2,40%丙溴磷乳油480和500 g/hm2的防效均>80%;80%杀虫单可溶性粉剂650 g/hm2的防效达76.8%。但是4种药剂中只有3%甲氨基阿维菌素苯甲酸盐水乳剂毒性较低,更有利于可持续性无公害农业的发展,应用前景较好。Using rice variety Yanfeng 47 as the material, the field efficacy of 3% emamection-benzoate EW, 40% chlorpyrifos EC, 40% profenofos EC and 80% monosuhap WP on controlling Cnaphalocrocis medinalis Gnenee were studied. The results showed that the fast action, persistence and control efficacy of the four pesticides were better. Ten days after spraying, the control efficacy of 3% emamection-benzoate EW with dosage of 12 g/hm^2, 40% chlorpyrifos EC with dosage of 470 g/hm^2, 40% profenofos EC with dosage of 480 g/hm^2 were above 80% , and that of 80% monosultap WP with dosage of 650 g/hm^2 reached 76. 8%. 3% emamection-benzoate EW had a low toxicity, which was more conducive to the development of sustainable and pollution-free agriculture, and the application prospects was better.
