The experiment was conducted in solarium, in a pepper culture, using 2 hybrids: Red Night F1 for bell pepper and Kaptur F1 for long pepper. During the experiment, the influence of biological combat with natural predators and of chemical combat over the pepper production was observed, as well as plant reaction to management systems with 2 and 3 offshoots. Biological combat was made by introducing 3 times natural predators: first introduction 10 days after planting, to combat trips with Thripor-l with 500 insects of Orius laevigatus, the second one 14 days since the first, with Thripor-l with 500 insects of Orius laevigatus and half bottle of Swirski-mite with 25000 insects of Amblyseius swirskii and the last one 50 days since planting with Spidex with 2000 insects of Phytoseiulus persimilis to combat the spider (Tetranychus urticae). The results obtained showed that the best results were obtained from biological combat with natural predators for both pepper varieties. Regarding the number of offshoots, long pepper is more suitable for 2 off shoots management, while bell pepper for 3 offshoots management. Production per square meter (sqm) varied between 9.52 kg and 11.98 kg.
