摘　　要：采用"50目防虫网覆盖+黄板预警+适时喷药"技术进行番茄育苗,番茄出苗整齐,幼苗生长正常。而且隔离烟粉虱效果好,平均百株幼苗烟粉虱成虫12头,而常规露地育苗平均百株幼苗烟粉虱成虫410头,苗期减少喷药次数4～5次。采用50目防虫网全程覆盖栽培番茄黄化曲叶病毒病病株率在0.9%～2.8%之间,防控效果达90%以上,每667m2可挽回经济损失6329.5元。2007～2009年在温州苍南、瑞安、瓯海等地番茄生产基地应用防虫网覆盖防控番茄黄化曲叶病毒病,推广面积逾330hm2。Tomato （ Lycopersicon esculentum Mill. ） seedlings were cultured by using 50 mesh insect nets covering ＋ yellow board warming in advance ＋ spraying insecticide timely. The results showed that the tomato seedlings grew neat and normally. It could isolate whitefly （ Bemisia tabaci ） effectively with average 12 per 100 plants whitefly adults. While in conventional land-based breeding, the whitefly adults could averaged 410 per 100 plants. The seedling spraying times were reduced by 4-5 times. The incidence of tomato yellow leaf curl virus （ TYLCV ） were 0.9 %-2.8 % with full coverage of 50 mesh insect nets, and the prevention and control effect were over 90 %. It can avoid economic losses of 6 329.5 Yuan per 667 m2. This technology was applied in Cangnan, Ryan, Ouhai of Wenzhou region in 2007-2009. It can prevent TYLCV successfully and the applied areas have reached more than 330 hm2.
