growth and survival Variación fenológica de la composición química foliar de Nothofagus macrocarpa en relación al crecimiento y sobrevivencia de Ormiscodes sp. Rodrigo A Chorbadjian a*, Ana E Francino a *Autor de correspondencia: a Pontificia Universidad Católica de Chile, Facultad de Agronomía e Ingeniería Forestal, Departamento de Ciencias Vegetales, Santiago, Chile, rchorba@uc.cl SUMMARY Host phenology can affect leaf feeding insects through changes in foliar chemical-physical traits.
Santiago’s southern beeches (Nothofagus macrocarpa) form relic forest patches at the northernmost distribution range for the entire genus in America.
Outbreaks of leaf feeding species in the genus Ormiscodes (Lepidoptera: Saturniidae) have the potential to defoliate extensive areas of several Nothofagus species; yet the mechanisms regulating their population dynamics remain largely unexplored.
A univoltine Ormiscodes species that consumes N.
macrocarpa foliage from mid October to November was studied.
To investigate how host phenological variation in chemical traits relates with insect performance, larval growth and survival were determined at th...
