The human flea Pulex irritans Linnaeus, 1758 (Siphonaptera: Pulicidae) is one of the most
studied species together with the cat flea Ctenocephalides felis Bouché, 1835, because they
have a cosmopolitan distribution and are closely related to humans. The present study
aimed to carry out a comparative morphometric and molecular study of two different
populations of P. irritans (Spain and Argentina). Accordingly, internal transcribed spacer
(ITS) 1 and ITS2 of rDNA and the partial cytochrome c oxidase subunit 1 (cox1) and …
