不同种类粘虫板在六堡茶有机茶园的应用技术研究

Application of sticky insect traps in organic Liupao tea field

为了解天敌友好型色板与普通黄板对六堡茶有机茶园茶小绿叶蝉的诱捕效果,以及对天敌蜘蛛的影响,通过开展对比试验,调查不同时期、不同悬挂高度的两种粘虫板对茶小绿叶蝉和天敌蜘蛛的影响。结果显示,天敌友好型色板诱捕茶小绿叶蝉的效果较好,对天敌蜘蛛的影响较小。不同悬挂高度实验结果显示:6月份和8月份,天敌友好型粘虫板悬挂高于茶蓬面20 cm时对小绿叶蝉的诱捕效果优于10 cm,而7月份则是10 cm的悬挂高度诱捕效果较好;普通黄板悬挂高度为高于茶蓬面20 cm时对小绿叶蝉的诱集效果优于10 cm。

In order to investigate the effects of various insect traps on trapping Empoasca vitis and natural enemy spiders,a color insect trap with natural enemy amity(natural enemy friendly trap)was compared with a normal yellow insect trap in Liupao organic tea fields.The result shows that the natural enemy friendly trap,with less trapped spiders and more trapped Empoasca vitis,was more friendly to the natural enemy than the normal yellow trap.The results also show that the effect of hanging height of the trapping board on the trapping Empoasca vitis depended on the season,in which the number of Empoasca vitis trapped by the traps hanged at 20 cm above plucking table was significantly more than those hanged at 10 cm in June and August,while the number trapped by those hanged at 10 cm was significantly more than that trapped by those hanged at 20 cm in June.The normal yellow sticky insect trap hanging at 10 cm above plucking board showed better in trapping Empoasca vitis than that hanging at 20 cm.
