This study aimed to select tomato genotypes resistant to Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) due to nonpreference for oviposition and feeding, in CHOIce and no-CHOIce tests. The species used were Solanum lycopersicum L. (cv. Santa Clara, hybrids: Saladete Italian Ty Tyna, Santa Cruz Débora Ty, Salad Lumi, Saledete Italian Andrea Victory and Santa Cruz Ty Carina Ty), S. habrochaites S. Knapp & D.M Spooner (lines PI 134417 and PI 134418) and S. pimpinellifolium L. (lines NAV 1062 and PI 126931). In tests of nonpreference for oviposition the number of eggs per plant was counted at 24, 48 and 72 hours after the release of adults. For the tests of nonpreference for feeding the attractiveness of the larva to the genotypes in each replicate was assessed at 1, 3, 5, 10, 30, 60, 120, 360; 720 and 1440 minutes after the release of larvae and mass consumed by the larva. It was found that the tomato genotypes evaluated did not present nonpreference resistance for oviposition. However, the genotype PI 134417 presented nonpreference resistance for feeding.
