Determination of influence of microbiological preparations with the different mode of action on entomophages of pests of agricultural crops (trichogramma (Trichogramma pintoi Voeg.), encarsia (Encarsia formosa Gahan.), seven-spotted ladybird (Coccinella septempunctata L.)) was realized in the Republic of Belarus in the conditions of laboratory and field experiments. It was determined that the bacterial preparation baciturine, ps did not render any toxic effect on Encarsia formosa Gahan. and Trichogramma pintoi Voeg. The fungal preparation pecilomicine-B, ps in 1% concentration rendered the insignificant action on trichogramma pre-imago stage and encarsia imago flight after treatment at egg and larvae stages. The preparation Melobass, ps in 1% concentration showed a weak toxic effect on seven-spotted ladybird beetles; in 2% concentration of the preparation there was stated 40% demise of predator beetles. The biological preparations baciturine, ps, pecilomicine-B, ps, and phytoverm, 0,2%, emulsion concentrate did not render any toxic effect against cabbage aphid Diaeretiella rapae M. Int. and useful arthropods occurring in carrot and cabbage plantings
