The reproductive behavior of insects is characterized by two types of sexual encounter systems: 1) systems in which males have a resource required for a female and 2) the so-called resource-free systems in while a male has nothing other than sperm to give a female. Selection of the most competitive males in the first-type systems is usually considered from the sexual selection concept, i.e. male resource competition and female selection of a partner that has a better a resource, and appreciated from the individual reproductive success of individuals. The application of this approach to the second-type systems offers apparent problems. The data on possible mechanisms of male competition in the resource-free sexual encounter systems are analyzed using the swarming types of mosquitoes. It is shown that selection of competitive males may occur at several stages of reproductive activity and is determined by both the physiological and behavioral signs of individuals.
1）雄性拥有雌性所需资源的系统；2）所谓的无资源系统，即雄性除了精子之外没有其他东西可以给予雌性。在第一类系统中，通常从性选择的概念来考虑选择最具竞争力的雄性，即雄性资源竞争以及雌性对拥有更好资源的配偶的选择，并从个体的生殖成功来评估。将这种方法应用于第二类系统会出现明显的问题。本文利用蚊子的群居类型分析了无资源性接触系统中雄性竞争的可能机制。结果表明，有竞争力的雄性的选择可能发生在生殖活动的几个阶段，并且由个体的生理和行为特征决定。
