摘要
小贯小绿叶蝉是宜宾茶园主要害虫之一,为了解宜宾茶区小贯小绿叶蝉发生规律,2021-2023年调查早白尖5号、福选9号、福鼎大白茶园小贯小绿叶蝉1-3月越冬虫 口基数,4-7月虫口密度,发现宜宾地区小贯小绿叶蝉第一次成虫高峰期在5月份,重发生的概率达78％～83％,抗虫性表现为福鼎大白＞福选9号＞早白尖5号.掌握小贯小绿叶蝉以上发生规律,可为宜宾茶区早春适时防治提供参考.
Abstract
Empoasca onukii is one of the main pests in Yibin tea garden.To gain insight into the occurrence pattern of E.onukii in Yibin,we investigated the overwintering population of E.onukii in Zaobaijian No.5,Fuxuan No.9,and Fudingdabai tea garden from January to March,and the population density from April to July,2021 to 2023.It was found that the initial adult peak period of E.onukii in Yibin occurred in May,with a frequency of severe occurrence of 78％to 83％.The resistance of different tea tree varieties to E.onukii was highest in Fuding dabai,followed by Fuxuan No.9 and Zaobaijian No.5.Understanding the occurrence patterns of E.onukii can inform timely prevention and control in Yibin during the early spring season.
