山东茶区茶银尺蠖生物学特性初步研究

Preliminary Research on the Biological Characteristics of the Scopula subpunctaria in Shandong Tea Area

通过对茶银尺蠖生活史、生活习性的观察研究,明确了茶银尺蠖在山东茶区每年发生6代。对山东茶区茶银尺蠖各代各虫态发生期、历期,以及各代各龄幼虫历期进行了调查和统计,发现与南方茶区不同的是,茶银尺蠖在山东以蛹和幼虫2种虫态在茶树上越冬,越冬代卵的历期受温度影响较大,茶银尺蠖世代重叠严重。

Through the observation and research on the life history and living habits of the Scopula subpunctaria,it was found that there are 6 generations of Scopula subpunctaria per year in the Shandong tea area.The investigation of occurrence period of each generation and each insect state,each generation and each insect state period,and each generation and instar larvae period were conducted.Different from the southern tea area,the Scopula subpunctaria overwintered on tea trees in two states of pupa and larvae in Shandong,and the duration of overwintering eggs was greatly affected by temperature.Its generations overlapped seriously.
