摘要
烟蚜(Myzus persicae Sulzer)是为害烟草的一种主要害虫,而烟蚜茧蜂是烟蚜的优势寄生天敌。阐述了三明市烟区的主要特点,对三明市烟区烟蚜茧蜂防治烟蚜技术推广中存在温湿度不协调、技术掌握不全面等一些技术问题进行剖析,并提出了合理改造繁蜂大棚内部结构、强化繁蜂技术培训、合理选择寄主品种、严格水肥管理、改善棚内湿度、规范处理繁蜂烟株病虫害等措施,以提高烟蚜茧蜂的生物防治效果。
Myzus persicae Sulzer is a major post for tobacco ,while Aphidius gifuensis Ashmead is the parasitic natural enemy of Myzus persicae Sulzer. The main features of the tobacco area in Sanming City were expounded,some technical problems of the Myzus persicae Sulzer control by Aphidius gifuensis Ashmead were elaborated, which including temperature and humidity is not coordinated, the technology can not fully grasped etc, some available measures were proposed from reasonable transformation of the internal structure of the breeding Aphidius gifuensis Ashmead, strengthening the technical training,reasonable selection of host species ,strict management of water and fertilizer, improving the humidity in greenhouse etc,in order to improve the biological control effect ofAphidius gifuensis Ashmead.
