Neotropical Entomology 35(5): 671-676 (2006) Efecto de Dos Solanáceas Cultivadas sobre el Desarrollo y los Parámetros Poblacionales de la Polilla del Tomate, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae)RESUMEN -Tuta absoluta (Meyrick) es una importante plaga del tomate que puede utilizar también otras solanáceas como plantas huéspedes. Este trabajo evaluó el efecto del tomate, Lycopersicum esculentum Mill. y la papa, Solanum tuberosum 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 o ), 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 o = 48,92; T = 27,98, r = 0,14, en tomate; y R o = 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 T. absoluta 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.PALABRAS CLAVE: Insecta, amplitud de dieta, Lycopersicum esculentum, Solanum tuberosum, Manejo Integrado de Plagas ABSTRACT -Tuta absoluta (Meyrick) is an important tomato pest that also feeds on other hostplants from the Solanceae family. We studied the effect of two cultivated plants, tomato (Lycopersicum esculentum Mill.) and potato Solanum tuberosum L. on the development and populational parameters of T. absoluta 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. Agespecific survivorship and fecundity life tables were constructed in the laboratory to evaluate the following populational parameters: net reproductive rate (R o ), 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 o = 48.92; T = 27.98, r = 0.14; and on potato: R o = 14.43; T = 32.35, r = 0.08. Although results showed that tomato was a more suitable host-plant and had a bett...

“…Additionally, the leaf contact also significantly increased the number of eggs laid, thus leaf surface morphology and chemistry accordingly have importance for oviposition of T. absoluta (Proffit et al, 2011). The leaf trichomes also provide chemical and mechanical stimuli for egg laying by female insect (Torres et al, 2001). The egg develops into first instar larva which starts to wound the leaf to enter into the mesophyll tissue of leaves or other parts of the host plant.…”

“…Mostly, mated females of T. absoluta prefer leaves especially apex part for oviposition than the other parts of the tomato plant (Torres et al, 2001;Leite et al, 2004;Proffit et al, 2011;Cherif et al, 2013). This oviposition site preference could be associated with a lower calcium content of apical plant leaves than that of middle and basal leaves of tomato (Leite et al, 1999).…”

Continue climatic changes in the world enhance the emergence of invasive agricultural insect pests.Tuta absoluta is one of the most devastating tomato leafminer and it spreads extensively in almost all parts of the world. It is a serious threat for tomato production and it results in highest damage. T. absoluta has fast growth rate with developmental stages of egg, larvae, pupa, and adult and it adapts to different environmental conditions. A larva is the most destructive one that consumes preferably leaves, stems and fruits of the tomato plant by hiding within mesophyll of the plant tissues. Although different environmentally hazardous pesticides are used against T. absoluta, none of the insecticides give full control due to the resistance development. This problem calls an urgent search for eco-friendly alternatives to control this invasive insect. Recent investigations are focused on different environmental friendly approaches that inclusively termed as IPM strategies. These are cultural practices, biopesticides, and biological using parasitoids, predators, microbial cells, microbial products, RNAi, inheritance sterility development in insect and pest resistant plant cultivar production are considered as promising alternatives to control T. absoluta. Therefore, this review briefly describes the current status of these methods used to design suitable and sustainable management strategies against T. absoluta.

“…Tomato crop in the Mediterranean Basin and in Europe has been recently affected by the exotic pest Tuta absoluta. The tomato leafminer, T. absoluta, is a native micro lepidopteron of South America (Torres et al, 2001) and a major pest of tomato crop since its detection in the Mediterranean basin (Guenaoui, 2008). It was first recorded in Eastern Spain in late 2006 (Urbaneja et al, 2007), then Morocco, Algeria, France, Greece, Malta, Egypt and other countries (Roditakis et al, 2010, Mohammed, 2010.…”

The susceptibility of five tomato cultivars (Hybrid Alissa, Hybrid Elbasha 1077, Hybrid Hadir, Hybrid H9780 and Fyrouz) grown in Egypt to Tuta absoluta infestation was studied during the summer of 2012 before and after insecticide treatments. Four insecticides (Tracer (spinosad), Agriflex (abamectin+ thiamethoxam), Alferde (metaflumizone) and Larifos (chlorpyrifos)) were applied at the recommended rates for management of T. absoluta on tomato crop. The results showed that tomato varieties, Fyrouz and H9780 were the most susceptible to Tuta absoluta infestation (71.6%) followed by hybrid Alissa, hybrid Hadir, and hybrid Elbasha 1077 whereas the infestation were 68.7, 67.4, and 62.5 %, respectively. There were no significant differences estimated among tomato varieties except Elbasha 1077. The results also showed that Tracer was the most effective insecticide in reducing T. absoluta infestation on all tomato varieties followed by Agriflex, Alferde and Larifos. Among three time intervals in 1 st or 2 nd sprays, no significant differences were reported between all tomato varieties in infestation reduction of Tuta absoluta after all insecticides treatments.
