摘　　要：目的探讨蚤类昆虫及其宿主之间协同进化的有关证据。方法在查阅大量国内外文献的基础上,整理区系、分类、形态结构、生态等各方面资料加以综合归纳。结果一系列证据表明,蚤类昆虫及其所寄生宿主(啮齿类动物等)在长期的寄生与被寄生的过程中,经过互相斗争、对抗和互相适应的漫长进化过程,形成了相对比较稳定的宿主-寄生关系,是体表寄生虫协同进化程度较高的一个类群。结论蚤类昆虫及其宿主之间存在程度较高的协同进化关系,是长期进化的结果,深入研究蚤类昆虫及其宿主之间的协同进化关系具有重要的学术意义。Objective To find a few evidences for coevotution of fleas and their hosts. Methods To review the domestic and oversea literatures and related data of the fauna, taxonomy, morphology and ecology of fleas. Results A series of evidences revealed that fleas and their corresponding hosts had formed a relatively stable relationship with parasitism through a long history of evolution and systematic development. The establishment of coevolution was the result of a long history of struggle, compromise and co - adaptation between the fleas （ectoparasites） and their hosts （ eg. rodents）. Conclusions A relatively high coevolution exists between fleas and their hosts, which is the result of long history of evolution. It is of significance to make a further research of the coevolution between fleas and their hosts.
