【摘要】 通过2016—2021年田间定点调查，研究茶园小贯小绿叶蝉[Empoasca(Matsumurasca)onukii Matsuda]发生规律及黄板悬挂朝向对其诱集效果。结果表明，小贯小绿叶蝉全年大多有2个发生高峰，第一个高峰在5月中旬至7月上旬，第二高峰在9月上旬至10月下旬，少数年份仅有一个高峰，发生在6月中旬至7月下旬；成虫占比少于若虫；不同悬挂朝向黄板诱杀效果为南北向>北向>东西向>东向、西向和南向。更多还原

【Abstract】 The occurrence regularity of Empoasca(Matsumurasca)onukii Matsuda in the tea garden and the trapping effect of yellow board hanging orientation on it were studied by field survey from 2016 to 2021. The results showed that there were two peaks in most years,the first peak was from mid-May to early July,the second peak was from early September to late October,and there was only one peak in a few years,which occurred from mid-June to late July;the proportion of adults was less than that of nymphs;the trapping effect of the yellow sticky trap with different hanging directions was north-south > north > east-west > east,west and south.更多还原
