| 摘 要： | 本文根据前齿肖蛸(Tetragnatha praedonia L,koch 1898)生活史试验中的幼蛛存活率,雌蛛产卵率、产卵量和孵化率组建了前齿肖蛸的世代实验种群生命表。结果表明:前齿肖蛸第二代的种群增长指数最大,达66.52;第四代种群增长指数最小,为14.60。

| Abstract: | This article , based upon the spiderling survival rate, egg-laying rate . number of eggs laid and hatching rate from the life history of T. pruedimu, attempts to set up a generation life table for experiment population. The experimental result shows that the maximum population increase index for the second generation is 66. 52, and the minimum population increase index for the fourth generation is 14.60. |
