[Natural development of epizootics due to the fungus Coelomomyces iliensis and their importance in regulating the number of blood-sucking mosquitoes of the genus Culex in Kazakhstan].

Observations have shown that the fungus Coelomomyces iliensis can be spread with the water current by means of shallow water species Aplocheilus latipes, Pseudorasbora parva, larvae of beetles of the family Dytiscidae, flies Musca domestica and ants.
