Efecto del sombreado de los montes forestales sobre la comunidad de hormigas cortadoras del género Acromyrmex: Consecuencias para el manejo de plagas

Abstract

Todas las especies forestales cultivadas en Sudamérica son atacadas por las hormigas cortadoras del género Atta y Acromyrmex (Forti y Boaretto, 1997), que son los herbívoros nativos dominantes en la zona neotropical y se consideran un componente fundamental de la conformación de los diferentes ecosistemas de Sudamérica (Cherrett, 1989; McNaughton, Sala y Oesterheld, 1993). Durante el forrajeo, las obreras cortan vegetales para cultivar un hongo simbionte del que se alimenta toda la colonia (Weber, 1972). Debido a este particular hábito de alimentación, las hormigas cortadoras causan serios perjuicios al sector agrícola y forestal, y son consideradas la plaga agrícola más importante de la zona neotropical (Cherrett, 1986). Las pérdidas para cualquier tipo de cultivo recién implantado pueden ascender hasta el 100 % (Fowler et al., 1990). Cálculos realizados estiman que se pierden entre el 14 y el 14,5 % de árboles por hectárea en el caso de Eucalyptus y Pinus, llegándose a pérdidas del 40 % de árboles recién plantados (Forti y Boaretto, 1997; Montoya-Lerma et al., 2012; Pérez et al., 2011)...
