The paper presents results of investigations of fleas from Citellus pygmaeus obtained during epizootological surveys in 1972-1974 (the Ergenin ridge, Kalmyk ASSR). The most high number of the main species of fleas of C. pygmaeus was observed in the first year of epizootic on the background of great abundance of the host (over 30 specimens per 1 hectare). In the following years the decrease in the number of C. pygmaeus was accompanied by the fall in the fleas number. The distribution of different species of fleas in a microbiotope is uneven in various periods. In all periods in nests fleas of N. setosa were dominant while fleas of C. tesquorum were most abundant on the host. In burrows there was noted a change of dominant species: in the period of intensive epizootic of 1972 they were Ct. pollex and C. tesquorum, in 1973 during a slump of epizootic--C. tesquorum and N. setosa and in 1974 when epizootic was not discovered at all--N. setosa.
本文展示了1972 - 1974年（卡尔梅克自治州埃尔根宁岭）动物流行病学调查期间从矮黄鼠身上采集的跳蚤的调查结果。在动物流行病的第一年，在宿主数量众多（每公顷超过30只）的背景下，观察到矮黄鼠主要跳蚤种类的数量最多。在接下来的几年里，矮黄鼠数量的减少伴随着跳蚤数量的下降。在不同时期，微生物群落中不同种类跳蚤的分布并不均匀。在所有时期，巢中鬃眼蚤占主导地位，而田鼠角叶蚤在宿主身上最为丰富。在洞穴中，优势种类发生了变化：1972年动物流行病高发期是指突眼蚤和田鼠角叶蚤，1973年动物流行病衰退期是田鼠角叶蚤和鬃眼蚤，1974年完全未发现动物流行病时是鬃眼蚤。
