Abstract：. 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.
