Tomato is the highest economic value vegetable and the most cultivated all over the world. The intensification of its cultivation in greenhouses led to a series of phytosanitary problems, the most significant caused by tomato leafminer (Tuta absoluta Meyrick). In this work, the presence of T. absoluta was evaluated in three tomato materials grown under a greenhouse and their yields were quantified. The experiment was carried out in the Experimental Field located in the Department of Agricultural Sciences, National University of San Luis. The genotypes used were the hybrid Houdini (ToH) and the varieties Lomitero INTA (ToL) and Cherry Pomodoro Red Bunch (ToCh). They were planted in experimental plots, arranged in a completely randomized design with a density of 3.3 plants/m2. Each plot had 109 plants, of which 10 of each material were monitored, which were selected through systematic sampling and labeled for recognition. Weekly monitoring was carried out to collect performance data, which were statistically analyzed using non parametric methods. As a result of the observations, the presence of T. absoluta was not detected in any of the three tomato materials, so the incidence of the pest was zero. However, given the importance of this information, their productivity was analyzed, with average yields of 3.14 kg/plant for ToH; 0.80 kg/plant for ToL, and 0.79 kg/plant for ToCh. ToH presented the highest yield and constant production over time, so its use could be recommended for the area.
