The objective this work was to evaluate the potential interference of two types of management of leafminer populations and their parasitoids under commercial production conditions of lettuce in plastic tunnels in the state of Minas Gerais, southeast Brazil. The comparison between conventional management using calendar sprays of insecticides, and ecological management with Bacillus thuringiensis, sticky traps and pheromones, showed that ecological management has several advantages over chemical control. In the plastic tunnel with ecological management lower numbers of leafminers emerged, a greater number of parasitoids emerged, the control costs were lower and the commercial value was equivalent to the conventionally managed crop.
