The interactions of two economically important gall midge species, the rice gall midge and the Hessian fly, with their host plants, rice and wheat, respectively, are characterized by plant defense via R genes and insect adaptation via avr genes. The interaction of a third gall midge species, the orange wheat blossom midge, with wheat defense R genes has not yet exhibited insect adaptation. Because of the simple genetics underlying important aspects of these gall midge-grass interactions, a unique opportunity exists for integrating plant and insect molecular genetics with coevolutionary ecology. We present an overview of some genetic, physiological, behavioral, and ecological studies that will contribute to this integration and point to areas in need of study.
两种具有重要经济意义的瘿蚊物种，即稻瘿蚊和黑森瘿蚊，分别与它们的寄主植物水稻和小麦之间的相互作用，其特征在于通过R基因进行植物防御以及通过avr基因进行昆虫适应。第三种瘿蚊物种，即麦红吸浆虫，与小麦防御R基因的相互作用尚未表现出昆虫适应。由于这些瘿蚊与禾本科植物相互作用的重要方面存在简单的遗传学基础，因此存在将植物和昆虫分子遗传学与协同进化生态学相结合的独特机会。我们概述了一些遗传、生理、行为和生态研究，这些研究将有助于这种整合，并指出需要研究的领域。
