Fleas From Pharaonic Amarna

Abstract

The preservation of ectoparasites in archaeological sites is normally problematic, but the dry environment of the Egyptian desert keeps even the very fragile remains of fleas intact.Fleas, Siphonaptera, can be divided in three large groups: the sedentary fleas that live in the nest of their hosts, the mobile fleas that still require a nest but can also live on the host, and the stick-tight fleas that attach themselves on the host. The human flea, Pulex irritans L. is one of the mobile fleas, nowadays cosmopolitan, and has been found on a wide range of hosts (Hopla 1980; Cooper 2001). Man evolved in the Old World and although the human flea is closely associated with him, it probably has a New World origin (Hopla 1980: 201; Traub 1985: 408; Buckland & Sadler 1989), as all its congeners are found in the Americas. Donkin (1985) thought that the original host for P. irritans was the peccary (family Tayassuidae). However peccaries do not have relatively permanent nest sites, and Buckland & Sadler (19891, after examining the profiles of different animal hosts, have suggested Cavia porcellus L., the guinea pig (cavy) as the primary host for the flea. C. porcellus was domesticated during the pre-Colombian period for its meat, but its contribution to the South American agricultural economy has always been on a local scale. Recent archaeological finds of Pulex sp. on a pre-Columbian C. porcellus from Peru (Dittmar 2000) support the above hypothesis.
