          Abstract

          Los objetivos de este estudio fue evaluar la efectividad de tratamientos térmicos con aire caliente forzado húmedo en el combate de la mosca de los zapotes (Anastrepha serpentina Wiedemann) "in vivo" y determinar la tolerancia a las condiciones aplicadas de frutos de zapote mamey. Los frutos no fueron dañados internamente por el tratamiento térmico cuando fueron expuestos a 43 °C·120 min-1. Los frutos alcanzaron su madurez de consumo a los ocho días a 25 °C, presentaron cambios rápidamente en color y perdieron más peso; mientras que, a 10 °C se mantuvieron con mayor firmeza, prolongaron su vida de anaquel y mostraron mayores daños en los haces vasculares. Con respecto a la mortandad de los huevos y larvas de mosca de la fruta A. serpentina, éstas fueron del 100% con la atmósfera controlada (CA) de aire caliente a 43 °C·120 min-1, igualmente los frutos no fueron dañados por la aplicación de la CA; las larvas murieron fácilmente por el calor a 40 °C·120 min-1, mientras que los huevos fueron más resistentes ya que ocurrieron larvas emergidas a 25 °C para los ocho días de almacenados.

          Translated abstract

          The objectives of this study were to evaluate thermal treatments of vapor heat in the control of Anastrepha serpentina on zapote and to determine tolerance of zapote mamey fruits to the treatments. The fruits not were damaged internally by the heat treatment when exposed to 43 °C·120 min-1. The fruits reached eating ripeness in 8 days at 25 °C, with rapid changes in the pulp color and weight loss. In contrast, at 10 °C they maintained greater firmness and prolonged shelf life, but exhibited greater damage in the vascular bundles. Mortality of the fruit fly eggs and larvae was 100% with controlled atmosphere vapor heat treatment at 43 °C·120 min-1. Fruits not were damaged by the application vapor heat; larvae were easily killed by the CA at 40 °C·120 min-1, but eggs were more resistant and hatched at 25 °C after the 8 days of storage.

            Molecular aspects of cell wall modifications during fruit ripening.

            Fruit ripening is associated with cell wall modifications. The present review focuses on cell wall components and the nature of noncovalent and covalent interactions in the primary cell wall. The role of structural protein cross-links are evaluated within the context of cell wall-mediated changes in texture during fruit ripening. The article discusses molecular approaches in fruit cell wall interactions to regulate processes in fruit ripening in order to improve post-harvest textural characteristics.
