Resumo: This work had the objective to verify the relation between 2-tridecanone (2-TD) in selected plants and resistance level to tomato pinworm (Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae)) in advanced generations of Lycopersicon spp. interspecific crosses. It was used a tomato population (F4RC2 generation) segregant for 2-TD, a methyl ketone that controls the resistance of the tomato pinworm. Materials were selected and evaluated for a non-preference mechanism of resistance. Three genotypes with high level of the allelochemic 2-TD (HI1, HI2, HI3), two with low level (LO1, LO2) and two check genotypes were used. After a controlled infestation, oviposition preference, type and percent of leaflet damage, and damage index caused by the tomato pinworm were evaluated. Plants with high level of 2-TD (HI1, HI3) had a low progression of leaflet damage by Tuta absoluta. The LO1 genotype was much attacked by the tomato pinworm, while the LO2 genotype was accidentally attacked by acari of the Tetranychus genus, probably causing a dispute between the two arthropods. It was concluded that 2-TD high levels are associated to non-preference ovipositions and feeding resistance mechanisms to tomato pinworm.

Foi usada uma população de tomateiros segregantes (geração F4RC2) para 2-TD, uma metilcetona que confere resistência à traça-do-tomateiro. Genótipos foram selecionados e avaliados quanto à resistência do tipo não-preferência: três materiais com alto teor do aleloquímico 2-TD (HI1, HI2, HI3) e dois materiais com baixo teor (LO1, LO2), além das testemunhas. Após infestação controlada, foram avaliados: contagem do número de ovos postos, evolução da lesão nos folíolos, porcentagem de folíolos atacados, e índice geral de lesão causada pela traça. Plantas com alto teor de 2-TD (HI1 e HI3) tiveram uma baixa progressão das lesões ocasionadas pelo ataque de T. absoluta. A planta LO1 foi muito atacada pela praga, o mesmo não ocorrendo com a planta LO2, que foi infestada acidentalmente por ácaros do gênero Tetranychus, acarretando, provavelmente, uma disputa de nicho ecológico entre os dois artrópodes. Concluiu-se que altos teores de 2-TD estão ligados a mecanismos de resistência à traça-do-tomateiro do tipo não-preferência por oviposição e alimentação.
