摘  要:
1.三化螟卵、幼虫和蛹的发育起点和发育零点都系实测结果。卵的孵化零点为16℃,胚胎发育零点为15℃,幼虫发育零点为12℃,幼虫的化蛹零点和蛹的羽化零点都为15℃。 2.三化螟各虫态的有效积温,卵平均为81.1日度,幼虫为507.2日度,蛹为103.7日度,共计为692.0日度。卵和蛹的有效积温随着温度的上升而增加,而幼虫的则恰为相反。 3.发育零点的测定方法有实测,计算和图测三种。后面两种方法所得的结果都与实测的有一定的距离。

摘  要:
The determination of the mininum temperatures of development were carried out directlyunder lower temperatures. The results obtained are shown as in the following: The effective thermal summation fluctuates with temperature in a certain extent. Incase of egg and pupa, it increases in proportion to temperature, while in larva, it decreaseswith the rise of temperature.
