| 摘 要： | 在５种温度下观察了深点食螨瓢虫各虫态的生长发育及成虫产卵的情况，由此拟合了各虫态的发育速率和温度的关系模型，求出了各阶段的发育起点温度和有效积温，组建了４种温度下的实验种群繁殖特征生命表，并算出了内禀增长能力、稳定年龄组配、瞬时出生率和瞬时死亡率等参数值。

| Abstract: | The growth of each developmental stage and oviposition of adults of Stethorus punctillum were observed under five constant temperatures.From this,we fitted the models for the relationship between developmental rate and temperature,and calculated threshold temperature and effective accumulative temperature for each stage.we established fertility tables of experimental populations of S.punctillum ,and at each temperature computed the intrinsic rate of natural increase,stable age distribution,instantaneous birth rate and instantaneous death rate,etc. |

| Keywords: | Stethorus punctillum population development fertility table temperature. |
