天水柳叶蜂第1代各虫态发育起点温度和有效积温研究

The Determination of the First Generation of Tianshui willow-leaver-shaped Bee' Each Growth Phrase's Starting Point Temperature Development and the efficient Keeping Temperature

在自然变温条件下测定了天水柳叶蜂第1代蛹、成虫、卵、幼虫在天水市的发育速率、发育起点温度和有效积温值,并以此建立了发育期日均温T与发育速率V之间的线性回归方程,进行了显著性检验,可靠性均达0.99。

This article focuses on the determination of Tianshui Willow - Leaver - shaped Bee＇ first generation growth speed, the temperature of starting development and the efficient accumulation temperature in each development phrase like pupa, adult, egg and larva under the natural changing condition of temperature. Meanwhile, estabfished linear equations between the everyday average temperature＂ T＂ and the growth speed＂ V＂, which have been taken notable test and the reliability turns out to be 0.99.
