【摘要】 精子竞争(sperm competition)是雌性与多个雄性交配后,来自不同雄性的精子为了争夺对卵的受精权而展开的激烈竞争,是生殖竞争(reproductive competition)的最后阶段。对精子竞争机制的揭示是精子竞争研究的重要内容,该文分别对昆虫的4种精子竞争机制假说:精子分层、精子取代、精子失能和雌性的隐秘选择进行了重点综述,还对昆虫精子竞争产生的条件、精子竞争的模式及雄性对精子竞争的适应等方面做了阐述,并对精子竞争未来研究的方向做了展望。更多还原

【Abstract】 Sperm competition is the competition between the sperm from two or more males for the fertilization of the ova,and is the last step of the reproductive competition.The study of sperm competition is to reveal the mechanism of sperm competition.We review the sperm competition of insects from the following aspects: the condition of sperm competition,the patterns of sperm competition,the mechanism of sperm competition and the adaptation of male for competition.Besides we prospect the research trends of the sperm competition.更多还原
