摘　　要：本文论述了在9.1℃、13.5℃、16.5℃、及23.6℃实验条件下,落叶松叶蜂实验种群的发育速率,各发育阶段及整个世代的发育起点温度和有效积温。实验证明在24℃以上该叶蜂一龄幼虫不能成活,蛹不能羽化为成虫;7℃以下对蛹的发育有明显的阻碍作用;而高温条件(24.6℃)对雌成虫的产卵有明显的促进作用。Describes laboratory experiments on Pristiphora erichsonii ( Hartig ) carried out at temperatures 9.1℃, 13.5℃, 16.5℃ and 23.6℃to find out the developmental rate, initial developmental temperature and effective cumulative temperature. The 1st age larvae cannot alive and pupa cannot emerge when temperature is exceeding 24℃. Development of the pupa is inversely affected below 7℃.A higher tepmerature(24.6℃)favorurs ovipos ition remarkably.
