chewing lice (phthiraptera) of several species of wild birds in iran, with new records.

b ackground: although there are about 520 species of birds in iran, but only some of them have been checked for ectoparasites so far.the aim of this study was to check some more available species of the birds of iran for lice. m ethods: this study was performed between 2008–2010 in northern iran. for this purpose we tried to check some of the wild bird species available and mostly not checked before to identify the lice of them.the birds were found in some of the houses of hunters keeping as trap for catching more birds, some of the bird keepers and a few dead birds from taxidermists. in this way we could check 79 birds of 6 species. r esults: we identified 11 lice species on the birds and overall 15.2 % of the examined birds were infested by the lice. nine lice species including aquanirmus podicipis, pseudomenopon dolium, ardeicola sp, ciconiphilus decimfasciatus ; menacanthus sp, austromenopon transversum , pectinopygus gyricornis, colpocephalum turbinatum and hohorstiella lata were recorded for the first time on the birds in iran. one specimen of menacanthus sp was found on the purple heron ( ardea purpurea ) that is a new host report for this lice. c onclusion: although the infection rate was not very high in the birds, but 11 species of lice in 6 studied birds spe- cies in this study, shows there are still other lice species that exist in the birds and should be identified and added to iran lice fauna list.
