When and how multiple species can or cannot coexist is a fundamental question in ecology. Recent theory suggests that mechanisms other than trophic tradeoff could enhance the coexistence of ecologically similar species, with a strong emphasis on reproductive processes. Therefore, how resource competition and reproductive interactions jointly drive competitive dynamics is an empirical question of interest. In this context, interspecific competition between two congeneric seed beetles, Callosobruchus maculatus and C. chinensis, is a particularly interesting system; they are ecologically similar, their reproductive biology is well understood, and the two species interact with each other reproductively (through reproductive interference). Here, I review the literature for those who are interested in studying the interspecific interactions within this system, with a special emphasis on their reproductive biology and reproductive interference. I also reanalyze the results of a previous study to provide additional insight. At the end of the paper, I suggest several future directions to encourage future work that could provide further general ecological and evolutionary insights.

种甲虫作为种间竞争的现代模型系统

多个物种何时以及如何共存是生态学中的一个基本问题。最近的理论表明，营养权衡以外的机制可以增强生态相似物种的共存，并重点强调生殖过程。因此，资源竞争和繁殖相互作用如何共同驱动竞争动态是一个有趣的实证问题。在这种情况下，两种同类种子甲虫Callosobruchus maculatus和C. chinensis之间的种间竞争, 是一个特别有趣的系统；它们在生态上相似，它们的生殖生物学被很好地理解，并且这两个物种在生殖上相互作用（通过生殖干扰）。在这里，我为那些对研究该系统内的种间相互作用感兴趣的人回顾了文献，特别强调了他们的生殖生物学和生殖干扰。我还重新分析了先前研究的结果，以提供更多见解。在论文的最后，我提出了几个未来的方向，以鼓励未来的工作，这些工作可以提供进一步的一般生态和进化见解。
