Observations were carried out during the spring-summer season 2021-2023. in the northern and southern parts of the Beltau LEA, where the population of the great gerbil reaches high densities and the number of these rodents varies widely. The survey was carried out in some areas of the Asian desert plague focus, in the Karakalpak Kyzylkum desert in 2021-2023. in the enzootic territories of Beltau, adjacent closer to the Takhta-Kupyr oasis. It is known that during declines in the population of the great gerbil, inhabited colonies often remain in groups with different numbers of colonies. Thus, the circulation of the plague microbe can occur even during periods of deep declines in the gerbil population.
