The tactics of Encarsia parasite application in tomato plantings based on greenhouse monitoring whitefly data monitoring and entomophage colonization at the beginning of the first phytophage imago with the repeated releases and during mass phytophage larvae hatching is scientifically substantiated. The efficiency of the combined release for greenhouse whitefly control of the inner parasite of phytophage larvae Encarsia (10 individuals/square m) and predatory bug macrolophus (5 individuals/square m) on protected ground tomatoes. Many times release of entomophage (4-6 times per season) gives an opportunity during the intensive tomato fruit bearing to delay phytophage number below the threshold value and to get the ecologically nert production
