Effect of two solanaceous plants on developmental and population parameters of the tomato leaf miner, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae)

Tuta absoluta (Meyrick) is an important tomato pest that also feeds on other host-plants from the Solanceae family. We studied the effect of two cultivated plants, tomato (Lycopersicum esculentum Mill.) and potato Solanum tuberosum L. on the d...

description	<i>Tuta absoluta</i> (Meyrick) is an important tomato pest that also feeds on other host-plants from the Solanceae family. We studied the effect of two cultivated plants, tomato (<i>Lycopersicum esculentum</i> Mill.) and potato <i>Solanum tuberosum</i> L. on the development and populational parameters of <i>T. absoluta</i> related with host-plant suitability. Larval developmental time, pupal weight, mean fecundity and an index of host-plant quality (IPQ = pupal weight / frass weight) were estimated. Ages-pecific survivorship and fecundity life tables were constructed in the laboratory to evaluate the following populational parameters: net reproductive rate (R<SUB>o</SUB>), intrinsic rate of increase (r) and generation time (T). Larval developmental time was shorter and pupal weight was higher (P < 0.0001) for larvae reared on tomato (P < 0.0001). Mean fecundity was not significantly different on both plants (P = 0.07) and food quality of host-plant was higher for tomato (P = 0.02). Mean population parameters on tomato were: R<SUB>o</SUB> = 48.92; T = 27.98, r = 0.14; and on potato: R<SUB>o</SUB> = 14.43; T = 32.35, r = 0.08. Although results showed that tomato was a more suitable host-plant and had a better nutritional quality than potato, when <i>T. absoluta</i> fed on potato the potential population increase requires attention. Under appropriate climatic conditions, spatial and temporal coincidence between crop and pest, <i>T. absoluta</i> could become a pest for the potato crop.
