铺石诱虫防治油松毛虫

LAYING STONES TO ATTRACT AND CONTROL DENDROLIMUS TABULAEFORMIS

本文是在理解昆虫习性和行为的基础上,设计出的一种简单而易行的油松毛虫防治方法。冬季之前,在树干基部铺放石块,集中引诱84.7％的油松毛虫来石块下越冬。有时一个石块下竟能引诱来一千多头油松毛虫,由于在整个冬季害虫集中存在,便于进一步采取人力的、化学的以及微生物学的杀虫方法。在试验中应用铺石诱虫取得了良好的防治效果。

This article is about a simple and easy method to control Dendrolimus tabulae formis based on the understanding of insect habits and behaviour. Laying some stones at the bases of trees before winter can attract 84.7% of D. tabulaeformis. They overwintered under the stones. Sometimes there were more than one thousand insects under one stone. Because they stayed there collectively during whole winter, it is easy to use manual, chemical, and microbiological methods to kill the insects. Good control effect was achieved by laying stones to attract insects in this experiment.
