| Abstract:
The efficiency of the natural enemies, for the biological control of main greenhouse pest was tested in commercially used greenhouses. Several predators and parasitoids commercially available were artificially introduced in two different commercial greenhouses planted out with tomatoes, aiming to biologically control the populations of spider mites (Tetranychus urticae), whiteflies (mainly Trialeurodes vaporariorum), aphids (Myzus persicae, Aphis gossypii, Macrosiphum euphorbiae and Aulacorthum solani) and leaf miners (Liriomyza spp.). Due to the proper use of the several biological agents (Phytoseiulus persimilis, Diglyphus isaea, Encarsia formosa + Eretmocerus mundus, Aphidius colemani and Aphidoletes aphidimyza) there were observed a considerable decrease of the dynamics of insect population, while there was a significant reduction of the pesticide use. It was proved that there are real possibilities of the effective implementation of the biological control in commercially grown greenhouses. Meantime, the farmer’s awareness for the extensive use of the environmentally friendly practices, for the greenhouse pest control was increased. | |
