Abstract: Studies on the trophic niche breadth and overlap of 46 species of flea in the southern slope of the Himalayas Mountains show that there were 23 species of flea only parasitized one kind of host, and their trophic niche breadth was the narrowest(B=0). Amphipsylla quadratedigita had the widest(B=0.6694) trophic niche breadth, and then, Neopaylla stevensi the second(B=0.4968). Among 12 dominant flea species lived on 9 small animal species, Xenodaeria telis, X. angustiproceria and Palaeopsylla tauberi mainly lived on Soriculus nigrescens, a kind of small insectivorous mammal, so the trophic niche overlaps among them were the highest.
