MENDOZA, Gabriel  y  JEREZ, Viviane. SOIL BEETLES ASSOCIATED WITH PEUMUS BOLDUS MOL. IN ISLA MOCHA NATIONAL RESERVE. CHILE (INSECTA - COLEOPTERA). Gayana (Concepc.) [online]. 2001, vol.65, n.2, pp. 129-136. ISSN 0717-6538.  http://dx.doi.org/10.4067/S0717-65382001000200004.

The taxonomic composition of beetles soil associated to the vegetable formation of Peumus boldus in Isla Mocha National Reserve were studied. The study was carried out in the spring and beginning of summer of 1998, by means of 10 pitfall traps placed along a longitudinal transect . Each trap remained on the sampling site during 15 consecutive days and the material recolected was preserved in alcohol, for its later identification. The results show that in the P. boldus shrubland the Order Coleoptera is represented by 15 families and 25 species. Germarostes posticus (Ceratocanthidae), Gnathotrupes corthyliformis (Scolytinae) and Aridius chilensis (Lathridiidae) were the most abundant species. We concluded that exist seasonal and habitat differences determined by the presence and abundance of some species of beetles
