The author discusses the difficulties involved in biological control of adult mosquitoes, arising mainly from the imposibility of defining centres of their occurence in habitats and their wide dispersal over a given area, which prevents a large part of the population being covered by control. There are two types of approach to the problems of the ecological control of mosquitoes over large areas by modyfications of the environment in such a way as to prevent dispersal flights and to concentrate the mosquitoes in defined habitats, making it difficult for tchem to reach humans. This method based on detailed analyses of the migratory phenomena of mosquitoes, was developed by Bek 1emisev (1949) and has been successfully applied in practice. Classic biological control of adult mosquitoes is based on utilization of population and biocenotic influences to reduce the abundance of mosquitoes in a habitat. In relation to population questions a discussion is given of methods of limiting the females' fecundity by radiological, chemical and genetic sterilization of males. In relation to biocenotic influences the author discusses the effects of predatory activities of different groups of animals (vertebrate and invertebrate) and of parasitism in limitation of the numbers of mosquitoes. Analysis of a large number of data showed, that biological control of mosquitoes produces successful result only in cases where there is disturbance of stabilisation of the biocenosis by the introduction of new predatory species, or change the habitat structure determrning the relationships between the prey and predator populations , for examples. A balanced biocenotic system usually maintains a relatively high level of numer of mosquitoes.
