Abstract: The product Trichotim has as a principle the insect Trichogramma sp. Trichogramma is a wasp measuring only 0.5 mm. It lays its eggs in the pests’ eggs, destroying them before they can damage the plants. Trichogramma is efficient in the destruction of 500 species of pests; the product developed based on this wasp has been homologated in Romania only for three such pests: cabbage moth (Mamestra brassicae), European grapevine moth (Lobesia botrana) and codling moth (Cydia pomonella). This wasp species, almost invisible, is extremely widespread. The main issue for researchers was how to capture it from the wild and then how to create the conditions necessary to make it multiply in an artificial environment. The product Trichotim has been tested for four years, an interval during which Trichogramma showed its efficacy in both laboratory cultures and in the cabbage gardens of some farmers in the Arad County to whom it was offered as a promotion. The costs are higher than in a treatment with chemical substances, but the cultures we obtained were less risky for our health. One gram contains about 50.000 eggs of Trichogramma, an amount sufficient to store the crop from 1 ha of cabbage, of grapevine or of apple trees. The product Trichotim is used in the control of pests of grains, maize, sunflower, rape, cabbage, peas, clover, alfalfa, grapevine, apple tree, plum tree, and ornamental plants.
