Analysis of the Occurrence of Beetles in Plantations of Eucalyptus camaldulensis Dehn. in Cuiaba, MT

ABSTRACT

The purpose of this work was to analyze the occurrence of the Bostrichinae, Platypodinae and Scolytinae subfamilies in the planting of Eucalyptus camaldulensis in Cuiaba, State of Mato Grosso, in the dry and rain seasons. The collections were performed fortnightly between April 2008 and March 2009, with the use of six ethanolic traps. Qualitative and quantitative studies were carried out concerning population fluctuation, frequency, constancy, abundance, dominance and diversity. Twenty-six species were found, with the Scolytinae subfamily yielding the largest amount of species and individuals in both periods. Hypothenemus eruditus and Xyleborus affinis in the dry season and Xyleborus ferrugineus in the rain season were the most quantitatively representative species.
