Caracterização da família Scolytidae (Insecta: Coleoptera) em três ambientes florestais

Abstract

Insects are potential cause of damage in forests and the family Scolytidae is responsible for major death of trees in the world. This research studied Scolytidae insects at three areas, two in rain forests and one in an eucalyptus plantation, through faunistic indexes, and to determined the correlation between number of Scolytidae and temperature and relative humidity. A total of fifteen ethanolic traps were used from July 1998 to June 1999. A total of 35 species of Scolytidae was identified, with 48.6% of then occurring at all areas. Twenty nine species were xylomicetophagus. The genus Xyleborus presented the higher number of species. In the Eucalyptus plantation area, six species constantly appeared and positive correlation (54.5%) was found between the number of insects and monthly mean temperature.
