Phenological variation in leaf chemistry of Nothofagus macrocarpa in relation to Ormiscodes sp. growth and survival

La fenologia de la planta hospedera puede afectar a insectos defoliadores a traves de cambios en rasgos fisico-quimicos de las hojas. Roble de Santiago (Nothofagus macrocarpa) forma bosques relictos al extremo norte de la distribucion del genero en America, constituyendose en un ecosistema unico. Ciclos poblacionales eruptivos de especies del genero Ormiscodes (Lepidoptera: Saturniidae) tienen el potencial de defoliar vastas areas de Nothofagus spp., pero los mecanismos reguladores de su dinamica poblacional han sido poco estudiados. Se estudio una especie univoltina del genero Ormiscodes que consume follaje de N. macrocarpa desde mediados de octubre a noviembre. Se evaluo la sobrevivencia y crecimiento larval al momento de su emergencia natural y al retrasarla 21, 30, y 79 dias. Se cuantifico la concentracion foliar de nitrogeno total y fenoles totales. Como resultado, se determino que la sobrevivencia y crecimiento larval decrecieron a medida que su emergencia se retraso. El crecimiento larval fue mas sensible a cambios en la calidad del follaje en comparacion con su sobrevivencia. La disminucion del crecimiento y sobrevivencia de los insectos se correlaciono significativamente con la concentracion de nitrogeno foliar, pero no con la concentracion de fenoles totales. Estos resultados indican que el momento de emergencia de las larvas, y la concentracion foliar de nitrogeno total son importantes factores que podrian tener un rol en la dinamica poblacional de este insecto
