Because of their particular biology, seed beetles exhibit a strong relationship with their larval host plants. In Europe, however, field data have long been scarce and unreliable. The results of Legume seed collections of nearly 1,000 samples belonging to 292 species from various locations in Europe are summarized. The status of current Bruchidius species groups is amended on morphological and phylogenetic bases. Recent advances in the knowledge of phylogenetic structures of both Fabaceae and Bruchinae provide a new picture of Bruchinae-Fabaceae interactions. It reveals a certain level of host conservatism. The hypothesis of radiative adaptation seems the most compatible with observed data.
由于其独特的生物学特性，豆象与其幼虫寄主植物之间表现出密切的关系。然而在欧洲，长期以来实地数据一直匮乏且不可靠。本文总结了来自欧洲各地、属于292个物种的近1000份样本的豆科种子收集结果。基于形态学和系统发育学依据，对当前布鲁奇迪乌斯物种组的分类地位进行了修订。豆科植物和豆象亚科系统发育结构知识的最新进展为豆象亚科 - 豆科植物的相互作用提供了新的认识。这揭示了一定程度的寄主保守性。辐射适应假说似乎与观测数据最为契合。
