德昌松毛虫文山松毛虫有效积温的初步研究

A Preliminary Study on the Effective Accumulated Temperature of D. punctatus techangensis and D. punctatus wenshanensis

摘要: 在室内自然温度条件下对德昌松毛虫(Dendrolimus punctatus techangensis Tsai)和文山松毛虫(Dendrolimus punctatus wenshanensis Tsai et Liu)各虫态的发育起点温度和有效积温进行测定,提出了各虫态有效积温预测式.

Abstract: Under natural temperature indoor, original temperature and effective accumulated temperature for various development stages of Dendrolimus punctatus techangensis and Dendrolimus punctatus wenshanensis were determined.The predicting formula for effective accumulated temperature of various development stage have been proposed.
