摘　　要：为了进一步明确当前防治褐飞虱主打药剂的田间效果。在大田中,采用喷雾施药法对10种杀虫剂进行了防治褐飞虱的田间试验。结果表明：用药3、7、14天后,对褐飞虱控制效果最好的是烯啶·吡蚜酮,达85.88%、96.81%、97.78%,最差的是吡虫啉,仅51.44%、65.40%、62.92%。用药21天后,对褐飞虱控制效果最好的是吡蚜酮＋毒死蜱,达96.81%,最差的是噻虫嗪,仅50.04%;防治效果在90%以上有吡蚜酮＋毒死蜱、烯啶·吡蚜酮、呋虫胺、吡蚜酮＋异丙威、吡蚜酮＋仲丁威5种;防治效果在80%-90%的有烯啶虫胺1种;防治效果在70%-80%的有吡蚜酮、噻虫嗪2种;防治效果〈70%的有吡虫啉、噻虫嗪2种。因此,呋虫胺、烯啶·吡蚜酮、吡蚜酮与毒死蜱、吡蚜酮与异丙威、吡蚜酮与仲丁威混用等5种药剂能有效控制褐飞虱为害。To understand the control efficiency on the brown planthopper, 10 insecticides were tested in rice through field spray. The results showed that, 3, 7 and 14 days after single spray, nitenpyram-pymetrozine got the maximum control effect of 85.88%, 96.81%, 97.78% and imidaclprid got the minimum control effect of 51.44%, 65.40%, 62.92%, respectively. While 21 days after single spray, pymetrozine mixing with chlorpyrifos got the maximum control effect of 96.81% and thiamethoxam got the minimum control effect of 50.04%. Among the tested insecticides, pymetrozine mixing with chlorpyrifos, nitenpyram - pymetrozine, dinotefuran, pymetrozine mixing with isoprocarb and pymetrozine mixing with fenobucarb got control effect above 90%; nitenpyram was between 80%-90%; pymetrozine and thiamethoxam were between 70%-80%; imidaclprid and thiamethoxam were below 70%. It was concluded that dinotefuran, nitenpyram · pymetrozine, pymetrozine mixing with chlorpyrifos, pymetrozine mixing with isoprocarb and pymetrozine mixing with fenobucarb can effectively prevent the attack by Nilaparvata lugens in rice.
