The results of studies on the formation of modern ways biocenotical direction of phytoprotection by entomopathogenic bacteria of Bacillus thuringiensis. It is shown that liquid formulations based on strains of B. thuringiensis first serotype H1 exhibit high biological activity against contact generations Leptinotarsa decemlineata Say. during ontogeny potato plants - 92.0 - 97.0 %, and entomotoxic action in relation to population Phthorimaea operculella Zell. in terms of storage - 77.0 - 85.0 %. In processing the tubers strains of B. thuringiensis significantly reduced population size herbivores (up 65.0 %) against the background of conservation to 72.0 % of tubers from potato moth settlement.
