设置黄板诱集成虫是斑潜蝇、白粉虱测报和防治的重要手段。通过在茄果类及瓜类蔬菜田的对比试验,结果表明,黄板下端高于作物顶部20cm的诱杀斑潜蝇、白粉虱虫量分别是黄板下端和上端与作物顶部平齐2种高度的1.2￣1.5倍和1.2￣1.6倍;20块/667m2插板密度诱杀斑潜蝇、白粉虱数量是10块/667m2的1.5￣1.6倍,与30块/667m2基本相当。试验为黄板诱杀斑潜蝇、白粉虱的防治技术提供了依据。
Set yellow trap entomology is Liriomyza sativae, whiteflies, an important means of detection and prevention. The results showed that the number of trap lurking leaf mullet at the lower end of the yellow plate was 20 cm above the top of the crop, and the numbers of the whiteflies were the same at the lower and upper ends of the yellow plate and the top of the crop, respectively Of 1.2 ~ 1.5 times and 1.2 ~ 1.6 times; 20 / 667m2 plug board density trap kill leafminers, whitefly the number of 10 / 667m2 1.5 ~ 1.6 times, and 30 / 667m2 basically the same. The experiment provided the basis for the trapping and killing techniques of the yellow leaf trap and the whitefly.
