Resumo: The objective of this research was to evaluate the influence of 2-tridecanone (2-TD) content on three tomato genotypes (TOM-556, HI-1 and PI 134417) in the parasitism of eggs of Tuta absoluta Meyrick, 1917 by Trichogramma pretiosum Riley, 1879. Two experiments were carried out to verify the parasitism in isolated and combined plants. The results in both experiments showed that the percent of parasitism of TOM-556 was significantly higher than the HI-1 and PI 134417. A higher percent of parasitism was observed in all strains when the eggs were placed in isolated plants. It is supposed that the presence of genotypes with different concentration of 2-TD in the same environment may have influenced the parasitic behavior of T. pretiosum.

Instalaram-se dois experimentos para verificar o parasitismo em plantas isoladas e em conjunto. A porcentagem de parasitismo em TOM-556 foi significativamente superior à verificada em HI-1 e PI 134417. Observou-se maior número de ovos parasitados quando contidos em plantas individualizadas. Supõe-se que a presença num mesmo ambiente de plantas com diferentes teores do aleloquímico possa ter influenciado o comportamento parasítico de T. pretiosum.
