This project aims to unravel the molecular basis of reproductive conflicts. Males compete for paternity and this continues after mating if females copulate and receive semen from multiple males. In ants and bees, molecules in males’ ejaculates recognise and kill rival males’ sperm. Reproductive proteins in leaf cutter ants’ seminal fluid may be the molecular agents of sperm competition. This project will investigate reproductive proteins and their functioning and effects on reproductive success. This project will show how reproductive conflicts over paternity operate on the protein level and may lead to novel avenues for future pest control.

该项目旨在揭示生殖冲突的分子基础。雄性会争夺亲子关系，如果雌性交配并接受多个雄性的精液，这种竞争在交配后还会继续。在蚂蚁和蜜蜂中，雄性射精中的分子识别并杀死竞争对手的精子。切叶蚁精液中的生殖蛋白可能是精子竞争的分子因子。该项目将研究生殖蛋白及其功能以及对生殖成功的影响。该项目将展示亲子关系的生殖冲突如何在蛋白质水平上发挥作用，并可能为未来害虫控制带来新的途径。
