中文摘要：
多次交配行为广泛存在于各种昆虫种类中。然而，目前对于昆虫多次交配行为的维持与进化的理解仍然存在疑惑。从物质利益和基因利益两方面综述昆虫多次交配发生的机制，并从亲代的产卵量、寿命、生殖力、子代的存活力与基因多样性等方面论述多次交配对昆虫适应性的影响。
英文摘要：
Multiple mating is common in many insects during their reproductive seasons, However, me understanding in maintenance and evolution of multiple mating behaviors remains controversial. In this paper, the mechanism of the occurrence of multiple mating is analysed from material and genetic benefits, and the influence of multiple mating on fitness in insects from parental fecundity, longevity, egg fertility, viability and genetic diversity of offspring is discussed.
