A method for controlling the spread and harmfulness of sawflies on currant includes techniques directed on keeping and accumulation of entomophage population. In the period of the beginning of mass egg laying of females of sawflies of the first generation single settling of a laboratory culture of an Trichogramma egg parasite of the Trichogramma dendrolimi Mats. species, onto bushes is carried out. In the period of emergence and egg laying of sawfly females of the second generation, two settlings of Trichogramma of the T. dendrolimi Mats. species. onto bushes are carried out. In the period of appearance of false larvae of the first generation of sawflies not elder than the second age, single settling of the parasite Oethophorus (Oethophorus naevius Gmel.) onto bushes is carried out. |
