Impacto de coleoptera cerambycidae em florestas de eucalyptus no Brasil

Abstract

The genus Eucalyptus is composed by 644 species, with a high number of varieties and hybrids (Pryor; Johnson, 1971). It was introduced in Brazil, from Australia, between 1865 and 1870. According to (Andrade, 1961), excepting five species from New Guinea and Timor, and one species from the Molucan Islands, all the species of Eucalyptus were from Australia and Tasmania, forming the several forests distributed along the American Continent. The genus was described by L ’ Heritier and is divided into eight Sections, based on the anther morphology. The Section Macrantherae includes the majority of the species.
