First report of Chalepus dorni (Coleoptera: Chrysomelidae: Cassidinae) in maize crops of Minas Gerais, Brazil.

Abstract

Chalepus dorni larvae were observed in commercial maize crops in the central region of the state of Minas Gerais, Brazil, during 2006-2007, 2008-2009 and 2010-2011 harvests. Early symptom of attack was characterized first by mines in the lower leaves of maize plants and later by the formation of necrotic areas. Although, there are reports of genus Chalepus in maize, this is the first record on the presence of C. dorni in maize in Minas Gerais, Brazil.
