摘要
本文根据圆尾肖蛸(Tetragnatha vermi formis Okuma 1982)在六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,组建了圆尾肖蛸在不同温度条件下的实验种群生命表。结果表明,在29℃的恒温条件下,圆尾肖蛸的种群增长指数最大,为51.71;高温35℃种群增长指数最小为11.70。温度与种群增长指数的关系可用以下方程表述:y=443.2383-36.5959x^2+0.7970x^2(20≤x≤29)。y=1275.3143-71.6280x+1.0150x^2(29≤x≤35)。(x=温度,y=种群增长指数)
Under different temperature conditions, T. vermiformis shows a different developmental duration, survival rate of spiderlings, egg-laying rate and nuber of eggs laid, and hatching rate. From these date is drawn a life table of experimental populations under six different constant temperature, which shows that there is the highest population increase index of 51.71 at 29℃, and the lowest index of 11.70 at 35℃, The interrelation between the temperature and the population increase index is expressed by the formula:Y=443.2383-36.5959x+0.7970x^2(20≤x≤29)Y=275.3143-71.6282x+1.0150x^2(29≤35≤)(x=Temperature, Y=Population increase index)
