黄板诱杀技术在防治葡萄斑叶蝉成虫中的应用研究

Trapping and killing adults of grape leafhopper(Erythroneura apicalis Nawa) by using yellow sticky traps

采用粘虫板对葡萄园内的葡萄斑叶蝉成虫黄板诱杀技术进行了研究，并对不同黄板的诱杀效果做了比较。结果表明：冀林黄板每天每板平均诱虫量为48．5头，效果明显优于其他两种黄板，市售黄板和自制黄板。北向黄板诱虫量与南向诱虫量有显著性差异。黄板悬挂高度10cm为宜。密度30～40块／667m^2，即可达到控制葡萄斑叶蝉危害的目的。

The trapping technology used for controlling adults of Grope Leafhopper （GLA） （ Erythroneura apicalis Nawa） by yellow sticky traps in the grapery was studied;the trap efficiency of different kinds of yellow sticky traps was tested.The results showed that about 48.5 GLA was trapped per template a day on average by Ji - Lin brand yellow sticky traps, obviously higher than the other two kinds of commodities and self- made ones. The number of the GLA trapped by the yellow sticky traps hanged in northern side and south side was obviously different. For the height, yellow sticky traps placed at 10 cm higher than the grape leaves caught the most GLA. For density of the traps, it was suggested that 30 - 40 traps per 667 square meters could achieve the goal of controlling GLA.
