采用数叶调查法、黄板诱捕法及有关分析软件，研究陕西眉县猕猴桃园重要害虫单片膜瓣叶蝉的种群消长动态，以及黄板不同悬挂高度及方向对单片膜瓣叶蝉诱捕作用的影响，为单片膜瓣叶蝉的绿色防控奠定基础。结果表明:陕西眉县猕猴桃单片膜瓣叶蝉若虫发生呈三峰型曲线变化，成虫发生呈双峰型曲线变化，6月成虫虫口开始快速上升，7月中旬到达第1个发生高峰，9月下旬出现第2个发生高峰;5月若虫虫口开始快速上升，发生高峰期分别出现在5月上旬，6月初和7月中旬;黄板对单片膜瓣叶蝉的诱捕效果最好，绿板其次，蓝板和白板对叶蝉的诱捕效果较差;不同月中黄板悬挂高度对单片膜瓣叶蝉的诱捕效果不同，6月和8月距地面60 cm、90 cm、120 cm和150 cm 4个悬挂高度之间效果不存在明显差异，7月距地面90 cm处效果最好，10月距地面150 cm处效果最好。
Population Dynamics of Membranacea unijugata and Trapping Effect of Color Boards in Meixian Shaanxi
A leaf counting survey,yellow boardtrapping method,and related analysis software were used to investigate the population dynamics of Membranacea unijugata,an important pest in ki-wifruit orchards in Meixian County,Shaanxi Province,as well as the effects of yellow boards with different hanging heights and orientations on the trapping effect of Membranacea unijugata.The re-sults showed that the occurrence of nymph Membranacea unijugata in Meixian,Shaanxi showed a three-peak curve,and the occurrence of adult leafhopper showed a bimodal curve,and the adult popu-lation began to rise rapidly in June,reached the first peak in mid-July,and the second peak reached in late September;the population of the nymph Membranacea unijugata began to rise rapidly in May,and the peaks of the occurrence of this pest appeared in the first half of May,the early part of June,and the mid July;trapping effect of yellow boards was the most effective for the single leafhopper.The trapping effect of yellow boards on leafhoppers was the best,followed by green boards,blue boards and white boards,which were less effective;the trapping effect of yellow boards on leafhop-pers was different in different months,and there was no significant difference in the effect of the four hanging heights of 60 cm,90 cm,120 cm,and 150 cm in June and August,and the effect was the best in 90 cm in July,and the best in 150 cm in October.
