Mechanisms for development and maintenance in intrapopulation polymorphism of antennal segment number were studied in Callosobruchusbeetle species from both macroevolutionary and microevolutionary points of view. According to the reconstructed molecular phylogeny of the genus Callosobruchus, the antennal segment polymorphism independently evolved multiple times only in an African species clade. This indicates that phylogenetic effect contributed to the development of the polymorphism to some extent. Individuals with abnormal antennal segment number were selected. Mating among selection and control strains showed that having abnormal antenna was costly in females but beneficial in males. This result demonstrated for the first time that sexual conflict plays an important role in maintenance of polymorphism of not only often-reported ecological traits but also morphological traits.

从宏观进化和微观进化的角度研究了触角节数种群内多态性的形成和维持机制。根据重构的Callosobruchus属的分子进化，触角片段多态性仅在非洲物种分支中独立进化多次。这表明系统发育效应在一定程度上促进了多态性的发展。选择触角节数异常的个体。选择品系和对照品系交配表明，触角异常对雌性代价高，但对雄性有利。这一结果首次表明，性冲突起着重要的作用，在维护多态性的生态性状，但经常报告的形态性状。
