Les puces de marmottes dans les zones de peste enzootique du Tien Chan et des montagnes du Pamir et de l'Alaï. Fleas of the marmots in the plague enzootic areas of Tien Shan and Pamiro-Alaï mountains.

Résumé

Thirty-six species of Siphonaptera were found as a whole on grey and long-tailed marmots and in their nests in the plague foci of Central Tien Shan, Alai, Gissar and Talas mountain ridges as well as in Eastern Pamir where no plague was discovered. From 8 to 21 species occurred in each separate region, but only Oropsylla silantiewi, Citellophilus lebedewi and Rhadinopsylla ventricosa, specific parasites of marmots, were met with everywhere. They are most numerous parasites that numbers depend on mountain altitudinal zonality. Pulex irritans is also important component of the marmot flea fauna in some foci. The rest of 32 species comprised 0.3 per cent of all collected fleas. Such findings prove a weak parasitic contact between marmots and other animals living in the same habitats.
