摘　　要：【目的】建立百色市烟草病虫害预测预报网,为烟区提供病虫害发生预警信息;研究烟草病虫害综合防治技术,提高百色市烟草病虫害防治水平。【方法】2008～2010年,对百色市烟草主要病虫害发生动态进行监测,监测对象为烟草病毒病、黑胫病、青枯病、烟蚜、棉铃虫、斜纹夜蛾,并根据病虫害发生动态和预测预报结果,开展烟草病虫害综合防治示范。【结果】百色市烟区烟草病毒类病害以烟草普通花叶病和烟草斑萎病为主;烟草黑胫病和青枯病发生较轻;棉铃虫发生为害较重,各烟区发生时间随移栽期不同而不同;斜纹夜蛾属中偏重发生;烟蚜的迁飞高峰随地域的不同而不同。烟草主要病虫害综合防治示范取得明显效果,2008～2010年病毒病发生率示范区比对照区分别低17.84%、8.28%和11.05%,黑胫病发生率分别低10.4%、14.18%和5.92%,蚜虫发生量分别低223、67和33头/百株,棉铃虫发生量分别低48、17和9头/百株,斜纹夜蛾发生量分别低5、17和13头/百株;示范区上等烟比例、产量、产值、均价等均高于对照区。【结论】百色市烟草病虫害预测预报及综合防治技术体系的集成应用可有效提高对烟草病虫害防治水平,经济效益和社会效益显著,可在各地烟区推广应用。[Objective]The present study was conducted to construct forecasting network of diseases and insect pests of tobacco in Baise to provide early warning on diseases and insect pests in tobacco-growing areas,and to find out integrated control techniques for diseases and insect pests management in order to improve the existing control measures.[Method]From 2008 to 2010,the occurrence dynamic of main diseases and insect pests（including virus disease,black shank,bacterial wilt,aphid,Helicoverpa armigera,Prodenia litura fabricius）in tobacco were monitored,and integrated control of tobacco diseases and insect pests were practiced according to the occurrence dynamic and the result of prediction.[Result]The main tobacco virus diseases in tobacco-growing areas of Baise were TMV and TZSV.Black shank and bacterial wilt occurred slightly,while the occurrence of Helicoverpa armigera was severe,and its occurrence time varied with the transplanting period.The occurrence of Prodenia litura fabricius was found from moderate to severe.The migration peak of aphid varied regionally.The demonstration of integrated control of main insect pests and diseases in tobacco achieved remarkable effects,the incidence of virus disease and black shank in experimental area decreased by 17.84,8.28 and 11.05% and 10.4,14.18 and 5.92% compared to the control area from 2008 to 2010,respectively.The number of aphid,Helicoverpa armigera and Prodenia litura fabricius in experimental area decreased 223,67 and 33,and 48,17 and 9/100 plants,and 5,17 and 13/100 plants compared to the control area,respectively.The rate of upper-quality tobacco leaf,yield,output value and the average price were higher in experimental area compared to the control area.[Conclusion]The system of the prediction and monitoring network of diseases and insect pests in tobacco and their integrated control techniques were helpful to enhance the control measures for diseases and insect pests,and could obtain significant economic and social benefits,and it should be extended and applie
