The research results have revealed the proteolytic activity of phosphate-mobilizing sporeforming bacteria of Bacillus genus which indices were even higher at bacteria cultivation on the gelatin media. Bacillus megaterium 2 had exhibited the highest activity among other 16 bacilli strains. Treatment of floral plants (coleus, pelargonium) planted in greenhouse, with the suspension of bacilli strains with different proteolytic activity had considerably decreased the quantity of greenhouse whitefly (Trialeurodes voparariorum) and green peach aphid (Aulacorthum circumflexsus) phytophages by 50–70 %. It was shown that subsequent treatment of the plants with suspensions of the studied bacteria is an effective biocontrol mean of phytophages quantity in greenhouse conditions.
