摘要

本研究以年齡齡期兩性生命表之理論分析姬龜瓢蟲（Propylaea japonica Thun-berg）之生長、發育及繁殖率等。以jackknife方法計算姬龜瓢蟲之內在增值率、淨增殖率與平均世代時間之平均值與標準機差。取食桃蚜之姬龜瓢蟲之卵期、幼蟲期、蛹期及成蟲期分別為3.2、7.5、4.2及48.8天，雄成蟲平均壽命為48.5天，雌成蟲為49.2天。內在增殖率為0.1253/天，淨增殖率為77.5子代/雌成蟲，平均世代時間為35.4天。此外並計算穩定年齡齡期分布、期望壽命及繁殖值。

The growth rate and developmental rate of Propylaea japonica Thunberg is analyzed based on the age-stage, two-sex life table theory. The means and standard errors of the intrinsic rate of increase, the net reproductive rate, and the mean generation time for P. japonica are calculated by using the jackknife method. The period of egg, larva, pupa and adult for P. japonica are 3.2, 7.5, 4.2 and 48.8 days. The intrinsic rates of increase for P. japonica is 0.1253/day. The net reproductive rate for P. japonica is 77.5 offspring/female; and the mean length of a generation is 35.4 day. The stable age-stage distribution, expectation of life and reproductive values were also calculated.
