Biologia e Preferência para Oviposição de Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae) em Folhas de Genótipos de Solanum tuberosum (L.) e Solanum berthaultii (Hawkes)
[Biology and preference for oviposition of Phthorimaea operculella (Zeller) (Lepidoptera: Gelechiidae) on leaves of Solanum tuberosum (L.) and S. berthaultii (Hawkes) genotypes]

Abstract: Effects of leaves of two introductions of Solanum berthaultii (L.) wild species, three Solanum tuberosum (L.) cultivars and two S. tuberosum x S. berthaultii hybrids on the biology and ovipositon preference of Phthorimaea operculella (Zeller) were evaluated under laboratory conditions. The growth, fecundity and adult longevity on the hybrids NYL 235-4 and N 140-201, with type A glandular trichomes, were similar to the observed on the cultivars Aracy, Apuã and Itararé. S. berthaultii PI 473331 (with type A and B trichomes) and PI 473334 (with type A trichomes) slightly affected the larval developmental time (PI 473331) and pupal weight (PI 473334). However, in free choice and no-choice tests, these introductions of S. berthaultii were not preferred for oviposition by P. operculella, while the other genotypes did not affect the insect oviposition.
