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.

Este trabajo evaluó el efecto del tomate, </i>Lycopersicum esculentum</i> Mill. y la papa, <i>Solanum tuberosum</i> L., sobre algunos aspectos del desarrollo y parámetros poblacionales relacionados con la calidad del alimento. Se midieron: duración del estado larval, peso pupal, fecundidad y un índice de la calidad alimentaria de la planta huésped (peso pupal / peso de heces). Por medio de tablas de vida en el laboratorio se obtuvieron datos de supervivencia y fecundidad específicas por edad con los cuales se calcularon: tasa reproductiva neta (R<SUB>o</SUB>), tasa intrínseca de crecimiento (r) y tiempo generacional (T). Los individuos alimentados con tomate tuvieron una menor duración del estado larval (P < 0,0001), y un mayor peso pupal (P < 0,0001) que con papa. La fecundidad promedio fue marginalmente más alta en tomate (P = 0,07) mientras que la calidad nutricional fue mayor para el tomate (P = 0,025). Los parámetros poblacionales promedio fueron: R<SUB>o</SUB> = 48,92; T = 27,98, r = 0,14, en tomate; y R<SUB>o</SUB> = 14,43; T = 32,35, r = 0,08 en papa. Si bien los resultados indicaron que el tomate exhibió una mayor calidad nutricional que la papa, las cohortes de <i>T. absoluta</i> alimentadas con este huésped secundario, mostraron un crecimiento relativamente importante. Bajo condiciones climáticas favorables y una coincidencia espacial y temporal entre la polilla y el cultivo de papa, sus poblaciones podrían convertirse en una plaga para el mismo.Facultad de Ciencias Naturales y Museo2006-10info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionArticulohttp://purl.org/coar/resource_type/c_6501info:ar-repo/semantics/articuloapplication/pdf671-676http://sedici.unlp.edu.ar/handle/10915/35142enginfo:eu-repo/semantics/altIdentifier/url/http://www.scielo.br/pdf/ne/v35n5/16.pdfinfo:eu-repo/semantics/altIdentifier/issn/1519-556Xinfo:eu-repo/semantics/altIdentifier/doi/10.1590/S1519-566X2006000500016info:eu-repo/semantics/altIdentifier/pmid/17144141info:eu-repo/semantics/openAccesshttp://creativecommons.org/licenses/by-nc/3.0/Creative Commons Attribution-NonCommercial 3.0 Unported (CC BY-NC 3.0)reponame:SEDICI (UNLP)instname:Universidad Nacional de La Platainstacron:UNLP2024-05-08T12:36:11Zoai:sedici.unlp.edu.ar:10915/35142Institucionalhttp://sedici.unlp.edu.ar/Universidad públicaNo correspondehttp://sedici.unlp.edu.ar/oai/snrdalira@sedici.unlp.edu.arArgentinaNo correspondeNo correspondeNo correspondeopendoar:13292024-05-08 12:36:12.197SEDICI (UNLP) - Universidad Nacional de La Platafalse
