摘　　要：在茶园树冠上方悬挂不同高度诱虫黄板,研究其对陕西茶区主要害虫小贯小绿叶蝉的诱杀作用,以及对天敌蜘蛛的影响,为陕西茶区主要害虫的综合治理奠定理论基础。结果表明:茶叶树冠上方30 cm处黄板诱捕的小贯小绿叶蝉成虫显著多于其他高度处黄板诱捕的成虫数量(P<0.05),树冠下方20 cm处黄板诱捕的蜘蛛显著多于其他高度处黄板诱捕的蜘蛛数量(P<0.05)。小贯小绿叶蝉在茶园的高峰活动时段在上午8:00和下午18:00,成若虫均符合这一规律。建议陕西茶区在小贯小绿叶蝉的发生期在茶叶树冠上方30 cm处设置诱虫黄板。Effects of yellow trapping card by hanging yellow card at different heights in tea garden of Shaanxi on the dominant pest [Empoasca（Matsumurasca） onukii]and spider natural enemies were studied to provide theoretical basis for comprehensive management of the dominant pest in Shaanxi.The results showed that the adult Empoasca（Matsumurasca） onukii trapped by card at 30 cm above tea tree crown were significantly more than that at other heights（P 〈0.05）.Spider natural enemies trapped at 20 cm below tea tree crown were significantly more than that at other heights（P〈 0.05）.The peak activity time of Empoasca（Matsumurasca） onukii was 8： 00 am and 6： 00 pm every daytime in Shaanxi tea plantation,the adult and nymph all accorded with this time regularity.It was suggested that yellow cards were set at 30 cm above tea tree crown during the occurrence period of Empoasca（Matsumurasca） onukii in Shaanxi tea plantation.
