摘　　要：为降低田间蚜虫数量,减少化学农药的施用次数,有效控制病毒病病株率及病情指数,通过推广蚜茧蜂防治烟蚜技术,探索生物防治在三门峡烟区的应用效果。结果表明,与常规对照相比,放蜂2次后,烟蚜虫口减退率达75.65%,有效控制了烟田蚜虫数量。病毒病病株率相对防效、病情指数相对防效分别为54.41%、62.41%,与常规对照相比差异显著(P<0.05)。释放烟蚜茧蜂后,减少了农药使用次数,防治成本减少50%以上,经济效益和生态效益明显提高。In order to reduce the number of aphids in the field, reduce the application times of chemical pesticides, and effectively control the virus disease rate and disease index, the application effect of biological control in Sanmenxia Area was explored by popularizing aphid cocoon bee control technology of tobacco aphid.The results showed that compared with the control group, the aphid population decline rate of tobacco aphid was 75.65%, which effectively controlled the aphid population. The relative prevention effect of virus disease rate and disease index were 54.41% and 62.41%, respectively, which were significantly different from the conventional control ( P < 0.05). After the release of aphid cocoon bee, the use of pesticides was reduced, the control cost was reduced by more than 50%, and the economic and ecological benefits were significantly improved.
