Results of search in natural bio-coenosis and study of biological and the insecticide properties of entomo-pathogenic fungi Metarrhizium anisopliae (Metsch.) Sor.and Paecilomyces fumoso-roseus (Wize) Brown et Smith are indicated in the article. As a result the number of M.anisopilae and P.fumoso-roseus local strains is isolated. Their morphological and cultural signs, enthomocidal activity in relation to the laboratory test-object (wax moth Galleria mellonella L.larvi) and to the target object (greenhouse whitefly Trialeurodes vaporariorum Wstw.larvi) are studied. As the most perspective as producer of biological preparations the strains of P.funoso-roseus P97,3/1 and 7/5 are selected. For the most active among them (the strain of P.fumoso-roseus 3/1) the values of medium lethal concentration (LC50) for II-III and IV instar larvi are determined
