FIELD: biotechnology.
SUBSTANCE: invention is a method for maintaining a stock culture of entomophage Trichogramma dendrolimi involves growing an entomophage on a surrogate host, wherein the surrogate host used is unfertilized eggs of a tobacco hornworm (Manduca sexta), successively conducting 2-5-fold passage with a final passage on the eggs of the natural host.
EFFECT: invention makes it possible to ensure effective maintenance of entomophage stock culture during absence of eggs of the main host – Siberian silkworm.
