THOMAZINI, ARIANE P.B.W; VENDRAMIM, JOSÉ D; BRUNHEROTTO, ROGÉRIO  e  LOPES, MARIA T.R.. Effect of Lycopersicon spp. genotypes on biology and oviposition of Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae). Neotrop. Entomol. [online]. 2001, vol.30, n.2, pp.283-288. ISSN 1678-8052.  http://dx.doi.org/10.1590/S1519-566X2001000200012.

This study evaluated, under laboratory conditions, the effect of tomato genotypes (Lycopersicon esculentum, cv. Santa Clara, Stevens and IPA-5; L. hirsutum f. glabratum, line PI 134417 and L. peruvianum line LA 444-1) on biology and oviposition of Tuta absoluta (Meyrick). The least adequate to the insect was LA 444-1 prolonging larval and pupal stages and reducing larval viability, pupal weight, fecundity and adult longevity, when compared to the control ('Santa Clara'). Line PI 134417 increased length of larval and pupal stages and reduced female pupae weight. Among cultivated tomato genotypes, the worst insect development occurred on 'IPA-5'. In this case, the length of larval and pupal stages increased and larval viability and weight of male pupae reduced. 'Stevens' was the only genotype which did not affect insect development when compared to control. Oviposition of T. absoluta was lower on wild tomatoes (PI 134417 and LA 444-1) than on cultivated genotypes, in free choice tests. Line PI 134417 was the only non-preferred to oviposition in a no choice test.
