A method of biological protection of vegetable plantations from aphid populations includes settling and using entomophages. In agrocenoses in spring and in the first half of summer the parasitoid wasp (Diaretiella rapae) is settled in three steps of five ones, and in the diapause period of the parasitoid wasp two settlings of the aphid midge are carried out. In addition, in late summer and autumn consecutive settlings of the predator and parasite are carried out with an interval of 12-15 days, alternating release thereof.
