分月扇舟蛾生物学特性及其综合防治

Biological characteristics of Clostera anastomosis and its integrated control

分月扇舟蛾在吉林敦化林区一年一代，以三龄幼虫在落叶间吐丝作茧越冬。该虫有两个 幼虫为害期，以五月下旬至六月上旬为害最为严重。初步查明，在敦化连续两年４、５月份干旱 和特殊林分环境是发生分月扇舟蛾幼虫为害的主要原因。本文还提出了分月扇舟蛾的综合防治 措施。

Clostera anastomosis which one generation per year in Duenhua forest region of Jilin Province. The survey indicated which making cocoon overwintering by 3 - instar larva in litter layer; two damage phase of the larva were very seriously at the last ten days of May and the first ten days of June; the main cause of the larva oc- curring infestation was special stand conditions after continuing drought last two years. In accordance with the above results, integrated control measures were suggested in this paper.
