Actividad biológica de Lonchocarpus guaricensis Pittier en el control de larvas de Tuta absoluta (Meyrick)
Biological activity of Lonchocarpus guaricensis Pittier was evaluated using two doses of Tecnona® in the control of larvae of Tuta absoluta (Meyrick), Azapa Valley, Chile, by a spray on potted tomato plants cv.

Naomi, randomly placed in a greenhouse within a nursery. Weeks prior to spraying, the pots were artificially infested with adults of phytophagous to obtain larvae in the leaflets. The evaluated treatments were the following ones: T1 (0.21 g AI of L. guaricensis·L-1), T2 (0.43 g AI of L. guaricensis·L-1), T3 (positive control based on spinosad 0.048 g AI·L-1) and T0 (negative control based on well water). According to the cumulative mortality percentage of larvae counted at 24, 48, 120 hours and 9th day post application, there was no statistical differences between T0 and T1 treatments, in turn, T2 reaches an average of 53.05% mortality not differing from T3 that achieves 73.9%. We conclude that the experimental dose of L. guaricensis 0.43 g AI∙L- 1 can be an attractive alternative for use in Integrated Pest Management of the tomato crop in the Azapa Valley. La actividad biológica de Lonchocarpus guaricensis Pittier fue evaluada utilizando dos dosis de Tecnona® en el control de larvas de Tuta absoluta (Meyrick), Valle de Azapa, Chile, mediante una pulverización sobre plantas de tomate cv. Naomi en macetas, ubicadas aleatoriamente en un invernáculo dentro de un vivero. Semanas previas a la pulverización, las macetas se infestaron artificialmente con adultos del fitófago para obtener larvas en los foliolos. Los tratamientos evaluados fueron los siguientes: T1 (0,21 g de IA de L. guaricensis·L-1), T2 (0,43 g de IA de L. guaricensis·L-1), T3 (control positivo a base de spinosad 0,048 g de IA·L-1) y T0 (control negativo a base de agua de pozo). De acuerdo con el porcentaje de mortalidad acumulada de larvas contabilizadas a las 24, 48, 120 horas y 9no día post aplicación, no hay diferencias estadísticas entre los tratamientos T0 y T1, a su vez, T2 alcanza una media de 53,05% de mortalidad, no diferenciándose de T3 que logra un 73,9%. Se concluye que la dosis experimental L. guaricensis de 0,43 g de IA∙ L-1 puede constituir una alternativa interesante de utilizar en el Manejo Integrado de Plagas del cultivo de tomate en el Valle de Azapa.
