中文摘要： 简要回顾昆虫交配系统的研究历史，并简述Bateman的性选择原理，讨论雌雄昆虫在交配过程中的角色和性选择压力的相对关系。一般而言，由于雌雄两性在交配过程中的角色和对后代投入的不同，往往是雄虫试图与尽可能多的雌虫交配，即雄虫使自己被尽可能多的雌虫接受，雌虫选择最好的雄虫进行交配，即雌虫选择交配对象。雄虫因而发展出各种类型的交配策略，以获取与更多雌虫的交配机会；而雌虫也通过交配选择权，选择对自己更有利的雄虫进行交配，雌虫在交配过程中除了可以获得基因利益，还可以获取物质利益。文章分别就昆虫的交配策略和利益展开叙述和讨论。
英文摘要：. We briefly reviewed the mating system of insects with emphasizing a historical research on the sexual selection conducted by Bateman. Thereafter, we described the relation of sexual pressure of each sex. female and male have different strategies to access a mating because of different efforts and input on their offspring. In general, male insects are eager to mate as many as females, or try to make him to be accepted by many females. In contrast, female insects choose the best male to mate, or females have a right to choose who is acceptable. Consequently, male insects evolved many kinds of strategies to access mating chances. On the other side, female insects can gain material benefits, besides for genetic benefits, through their choices. These strategies and benefits of insects were then described and discussed.
