| abstract | During 1963—1965 small mammals of 22 species were investigated: rodents, insectivorous and small carnivores. 31217 trombiculids of 22 species belonging to 11 genera were gathered from them. The highest indices of trombiculid quantity on the hosts are observed in the mountain zone, the least - in the alpine one. Out of the investigated animals the following ones are the main hosts (in a succession of their significance): Meriones tristrami, M. persicus, M. vinogradovi, Microtus socialis, M. arvalis, M. nivalis, and Mus musculus. Apodemus sylvaticus, Microtrombicula azerbaidjanica and Eltonella crinita are dominating species of trombiculids in the foothill and mountain zones, Neotrombicula sevaniensis — in the alpine one. |
