Development, reproduction, survival, and demographic patterns of Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) on different commercial tomato cultivars
Neotropical Entomology 46 (6), 694-700
Abstract: The increase in the production of tomato, Solanum lycopersicon Mill. (Solanaceae), has favored the proliferation of pests, especially Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae). In this study, the development, reproduction, survival, and demographic parameters of T. absoluta reared on six commercial tomato cultivars (Cherry, Cordilheira, Giuliana, Nemoneta, Paron, and Santa Clara) were evaluated. Tuta absoluta completed its development in all tomato cultivars. Development from newly hatched caterpillar to newly emerged adult varied between 24.8 and 28.2 days. Female fecundity ranged from 126.3 to 166.9 eggs, with fertility from 54.2 to 84.1%. Mortality during egg-adult development varied between 21.4 and 46.4% for insects reared on cultivars Cherry and Giuliana, respectively. The cultivars Cordilheira, Giuliana, and Santa Clara are promising options to tomato producers in order to decrease the attack and proliferation of T. absoluta. However, the development and population growth of T. absoluta is faster on the tomato cultivar Cherry.
