摘　　要：通过两年调查，明确了浙南菜区越冬番茄曲叶病毒病的主要侵染期在9月下旬至10月上旬，即番茄苗龄20～30d。温州近郊常年蔬菜生产基地，番茄曲叶病毒病的侵染循环主要通过携毒烟粉虱在越冬番茄和早春番茄间传播完成。苍南、瑞安等季节性番茄生产基地，该病的侵染循环主要通过携毒烟粉虱在越冬番茄、大田番茄苗和夏季南瓜等中间寄主传播完成。随着播种期推迟，番茄曲叶病毒病发生轻，目前浙南菜区生产上‘托马雷斯＇、‘好韦斯特’、‘合作903’等主栽番茄品种均表现感病。田间调查还表明，通过50目防虫网覆盖育苗栽培可以有效控制番茄曲叶病毒病发生，防控效果达到90％以上。A 2-year field study was conducted at the vegetable-planting areas of southern Zhejiang. The results showed that the main infection period of Tomato leaf curl Taiwan virus （ToLCTWV） was from late September to early October or at 20-30 d during tomato seedling stage. The virus was transmitted from winter tomatoes to the next generation tomatoes by whiteflies in suburban Wenzhou, but from winter tomatoes to summer pumpkins by whiteflies in Cangnan and Ruian of Wenzhou. With the sowing date postponed, tomato leaf curl virus disease occurred slightly. The current major tomato cultivars, ＇TamarW, ＇Haruest＇ and ＇Hezuo903＇, in southern Zhejiang were susceptible. Field surveys also showed that insect exclusion nets of 50 meshes can effectively control seedling tomato leaf curl virus disease, and the effects of prevention and control were over 90%.
