摘 要 ：本文根据前齿肖蛸(Tetragnatha praedonia)在20℃、23℃、26℃、29℃、32℃和35℃6种恒温条件下的发育历期、幼蛛存活率、成蛛产卵率、产卵量和孵化率组建了前齿肖蛸在不同温度条件下的实验种群增长表。结果表明前齿肖蛸在所试验的6种恒温条件下其种群数量可保持上升趋势,其中以在29℃的条件下种群数量增长最快,繁殖一代种群数量可增加74.28倍;以在20℃的条件下种群数量增长最慢,繁殖一代种群数量可增加20.74倍。

Abstract:Under different temperature conditions, T. praedonia shows a different developmental duration, survival rate of spiderlings, egg-laying rate, number of eggs laid, and hatching rate. From these data is drawn a life table of experimental populations under six different constant temperature, which shows that there is the highest population increase index of 74.28 at 29℃, and the lowest index of 20.74 at 20℃.
