| 中文摘要: |
| 卵袋是雌蛛产卵、若蛛孵化等繁育后代的保护性场所。常见农林蜘蛛横纹金蛛(Argiope bruennichi)一般一生产卵3~6次,织制卵袋3~6个。本文对横纹金蛛的体重、卵袋生物量、卵粒数与卵粒重进行了测试研究。结果表明,随着产卵次数增加,产卵间隔时间更长,但雌蛛产卵后至下一次产卵前生物量的增量在减少,而对卵袋生物量的投入却逐次增加,直至超过自身增加的生物量;随着雌蛛对卵块投入的增加,对卵袋丝的投入也增加,把更多的生物量投入到后代及对后代的保护中;随着产卵次数增加,卵粒数也增加,单粒卵重减少。横纹金蛛的产卵策略为随着产卵次数增加,把更多的能量投入到后代及对后代的保护中。 |
| 英文摘要: |
| The egg sac is the place of spider laying eggs and breeding offspring for the protection of future generations. Argiope bruennichi, a common forestry spider, generally produces eggs 3-6 times and weaves 3-6 egg cases. In this program, the weight, biomass of egg sacs and egg sac numbers of A.bruennichi fed at room temperature are studied. The results show that increased biomass decreased with the increase of the number of spawning egg sacs, but the input for egg sac increased successively; the input of the egg sac silk has also increased with the increase of spider invest for egg mass, which puts more energy for offspring; the number of eggs of per egg mass increased, and per egg weight reduced with the increase of the numbers of spawning egg sacs. |
