摘要
本文首次对贵州省赤水地区新发现的一种主要产虫茶昆虫紫斑谷螟Pyralis farinalis Linnaeus进行了报道.结合野外调查和室内饲养的方法,对紫斑谷螟的形态特征和生物学特性进行了较为系统的研究.结果表明,紫斑谷螟在赤水地区一年发生3代,以老熟幼虫在吐丝连缀茶叶形成的隧道内越冬.其中以越冬代历时最长,共经历约200d,越冬代成虫翌年4月下旬开始羽化;第1代历时最短,从5月上旬至7月上旬,仅经历约60d;第2代历时较长,从7月中旬到9月下旬,共经过约90 d.
Abstract
This article provides the first description of Pyralis farinalit Linnaeus, an insect which produces insect-tea in the Chishui area of Guizhou Province.The morphological and biological characteristics of this species were investigated both in the field and laboratory.The results show that P.farinalis has 3 generations per year in the Chishui area, and the old larva overwinter in a tunnel made of tea leaves and silk.The over-wintering generation was the longest, about 200 days, the adults of which emerged in late April.The first generation was the shortest, about 60 days, from early May to early July.The second generation was longer than the first, about 90 days from mid-July to late September.
