[Population density and area-specific distribution of the imago form of Hyalomma marginatum ticks, the vector of Crimean haemorrhagic fever, in Dagestan].

The results of the determination of the amount and location of ticks Hyalomma marginatum in Daghestan at the period of the appearance of cases of Crimean haemorrhagic fever (CHF) are presented. The domination and abundance indices of these ticks in different landscape areas, on the territories of some plain and foothill regions of the Republic of Daghestan are given. The advantages of the effective method for the collection of ticks "on the observer" have been substantiated. The data thus obtained are of importance for the epidemiological surveillance and prophylaxis of CHF.
