          Abstract

          O objetivo deste trabalho foi estabelecer as alterações na população de larvas de coleópteros do solo em diferentes ecossistemas de Araucaria angustifolia (Bertoloni) O. Ktze: mata nativa bem preservada; mata introduzida em Latossolo Amarelo apresentando diversidade intermediária de outras espécies vegetais e mata introduzida em Cambissolo com baixa diversidade vegetal e ocorrência de fogo acidental, no município de Campos do Jordão, SP, visando à preservação desta espécie arbórea. As larvas foram coletadas em superfície amostral de 25 × 25cm, nas profundidades do solo de 0-10, 10-20 e 20-30cm e na serapilheira. Foram coletadas dez amostras por ecossistema, nos meses de outubro de 2002 (período seco) e março de 2003 (período chuvoso). Em relação à mata nativa, foram observadas alterações na densidade e na diversidade das larvas nos ecossistemas introduzidos em Latossolo Amarelo e em Cambissolo. As características químicas e físicas do solo, aliadas às condições climáticas, contribuíram para as alterações nesta comunidade.

          This study was aimed to evaluate the alterations in the soil Coleoptera larvae population in different Araucaria angustifolia (Bertoloni) ecosystems O. Ktze: native forest well preserved; an araucaria forest area introduced on a Humic Hapludox with intermediate diversity of other vegetables species and forest area introduced on a clayey-textured Typic Dystrochept lower density of other vegetable species, which suffered impact by accidental fire, in the country of Campos do Jordão, São Paulo, Brazil, aiming at the preservation of this tree species. The larvae were collected on 25 × 25cm areas, in 0-10, 10-20 and 20-30cm soil depths and in the litter. Ten sampling points from each ecosystem were collected, in october 2002 (dry season) and march 2003 (rainy season). Changes in density and diversity of the Coleoptera larvae in the ecosystems with introduced araucaria on a Humic Hapludox and on a Typic Dystrochept were observed. The results suggest that there is a great influence of soil physico-chemical properties as well as of the climatic conditions upon this community.
