DE MORAES, CARLA PEDROSO  and  FOERSTER, LUÍS AMILTON. Development and reproduction of Neoleucinodes elegantalis (Lepidoptera: Crambidae) on tomato (Solanum licopercum) cultivars. Rev. Colomb. Entomol. [online]. 2014, vol.40, n.1, pp.40-43. ISSN 0120-0488.

The small tomato borer Neoleucinodes elegantalis (Lepidoptera: Crambidae) is one of the most representative pests of Solanaceae in Brazil and other South American countries. Due to the restricted knowledge about the influence of tomato cultivars on the biology of the species, the development and reproduction of N. elegantalis was evaluated on three tomato cultivars. In the hybrid Giuliana the development from oviposition to adult emergence was longest (56.2 days) in comparison to the cultivar Santa Clara (50.2 days) and the hybrid Paronset (50.7 days). Pupal weight was significantly lower in Giuliana. The mean fecundity of females fed on Giuliana during the larval stage was 88.6 eggs per female, 82.3 in Paronset and 37.0 on Santa Clara, but egg viability was higher for females fed during the larval stage on Santa Clara (79.0%). The hybrid tomato Giuliana had the highest impact on the development and reproduction of N. elegantalis. These findings can be useful as a plant resistance factor in the field to reduce the number of generations of the pest and to favour the action of natural enemies by decreasing the fitness of the pest.
