A method for short-term storage of laboratory cultures of Trybliographa (Trybliographa rapae West.) includes storing the biological material in laboratory conditions at the stage of adult insect. The parasite is stored by isolating adult individuals in a glass container of a volume of 1- where also sheets of pleated blotting paper are disposed. In addition, prior to the isolation the imagoes of the Trybliographa are fed for two days with a diet as a water solution of 0.02-0.03% RNA (ribonucleic acid) at an air temperature of 18±2 ° and a relative air humidity of 75±3%. The further three days the Trybliographa is stored at an air temperature correspondingly of 14±2 °; 11± ° and 8± °. In addition, the further 23-25 days imagoes of the parasite are stored at a temperature of 6± ° and relative air humidity of 68±2 %.
