观察了中华草蛉各发育阶段在不同定温下的发育速度,测得其发育始点和有效积温常数。运用测得的这些常数,推测中华草蛉在泰安1年发生代数和发生时期,与实测情况基本相符,在预测其发生期和地理分布时可供参考。
The developmental speed of P. chinensis at different developmental stages was observed and its developmental starting point and effective accumulated temperature constant were measured. Using these measured constants, it is speculated that P. chinensis occurs algebra and its occurrence period in Tai’an in one year, which is basically consistent with the measured data and can be used for reference in predicting its occurrence and geographical distribution.
