中文摘要:
      本文以对比行为实验方法研究了克氏原螯虾的交配行为。结果表明,克氏原螯虾交配过程可分为交配前期和交配期。在交配前期.雄虾表现出特有的交配前期行为;交配期包括钳夹、翻转、横跨、交尾和分离五个阶段。雌虾被雄虾钳住后表现顺从行为;而在对照组中的雌虾被同性钳住后却不表现顺从行为。雄虾之间的接触导致进攻行为。交配时雄虾横跨的步足均为右第5步足;雌虾在交配前勿需生殖蜕皮,交配的成败与雄虾接近雌虾的行为方式有关。且螯足较大的雄性个体交配成功率明显较高。
英文摘要:
      The mating behavior of the crayfish, Procambarus clarkii, was studies bycomparative behavior experiments. The mating process of the crayfish was divided intopremating phase and mating phase which included 5 events: (1)capturing; (2)turning; (3)crossing; (4) copulating; (5) disengaging. The behavior experiments revealed that thefemales displayed submitting behavior after being grasped by the males,but never after beinggrasped by same sex. The males showed premating behavior when closed to the females, butbecame rather aggressive when closed to the same sex. The crossing leg of the male inmating was confined to the right peraeopod. Whether a mating proceeds sucessfullydepended on how the male approached the female. The mean number of copulations perindividual was significantly greater for larger males than for smaller males.
