Resumen

REBOLLEDO R, Ramón; PALMA M, Rubén; KLEIN K, Carlos  y  AGUILERA P, Alfonso. COCCINELLINI (COLEOPTERA: COCCINELLIDAE) PRESENT IN DIFFERENT PLANT STRATA IN THE IX REGIÓN OF LA ARAUCANÍA (CHILE). Idesia [online]. 2007, vol.25, n.1, pp.63-71. ISSN 0718-3429.  http://dx.doi.org/10.4067/S0718-34292007000100007.

The greatest part of this research conducted in Chile regarding Coccinellini is related to their taxonomy, new registers, predatory activity or distribution. but there are only a few contributions about host plants of aphids that are visited by species of this tribe. The present research was developed in the five agroecological areas of La Araucanía (Chile) dividing the host plants intro three categories: herbal substrate, shrubs and trees. Coccinellini surveys were conducted in each category, including their relative abundance. Coccinellini were found on 26 herbs, 9 shrubs and 13 trees, being the host plants (Foeniculum vulgare) and different species of Cirsium outstanding considering the species diversity and the abundance of ladybeetles found on them. Eriopis spp. preferred herbs and trees and in a minor degree shrubs and, finally, Hippodamia spp preferred herbs and shrubs.

Palabras clave : Coccinellidae; IX Región La Araucanía (Chile); plant strata.
