[The epizootiological significance of flea accumulation in aggregations of the female long-tailed suslik in the Tuva plague focus].
The formation of aggregations of related females is a peculiarity of the intrapopulational organization of long-tailed suslik that results in the accumulation of Citellophilus tesquorum, the main vector and keeper of the plague microbe in the Tuva plague nidus. The plague agent is adapted to the existence on the territory occupied by aggregations of females that manifests itself in the delay of the beginning and prolixity of block-formation periods in fleas. The transfer of the agent from one place to another takes place only at the high abundance of long-tailed suslik. When the number of the suslik is low the plague microbe circulates in the ranges of one or several neighbouring aggregations of females having no possibility for successful transfer to a new place.
