摘要
根据星豹蛛(Pardosa astribera Koch)在20℃、23℃、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星豹蛛在不同温度条件下的实验种群增长表,结果表明星豹蛛在所试验的6种恒温条件下其种群数量可保持上升趋势,其中以在29℃条件下种数量增长最快、繁殖1代种群数量对增加37.78倍;以在20℃的条件下种群数量增长最慢,繁殖1代其中种群数量可增加15.77倍。
Under different temperature conditions ,developmental duration,survival rate of spiderlings.egg-laying rate,number of eggs laid,and hatching rate of P. atriena were different. From these datathe life table of experimental populations under six different constant temperature is drawn,which chows that there is the highest population increase index under 32 ℃ , being 37. 78, and the lowest index under 20 ℃,being 15.77.
