Plantations of Australian acacia, Racosperma mangium (Willd.) Pedley (Fabaceae), are option for commercial reforestations in the Amazon. The work aims, for the first time, report and describe injuries caused by Pelidnota filippiniae Soula, 2009 (Coleoptera Melolonthidae Rutelinae) in experimental plantation in Dom Eliseu County, Pará State, Brazil. Monthly observations were made from 2006 to 2009. Outbreaks occurred at the beginning of the rainy season, in October and November, in the early years of plantation when were observed different intensities of defoliation. Although significant damages have not been recorded, P. filippiniae has the potential to cause damages to this crop.

RESUMO
Plantios de acácia-australiana, Racosperma mangium (Willd.) Pedley (Fabaceae), são opção para reflorestamentos comerciais na Amazônia. O trabalho objetiva, pela primeira vez, reportar e descrever injúrias causadas por Pelidnota filippiniae Soula, 2009 (Coleoptera Melolonthidae Rutelinae) em plantio experimental em Dom Eliseu, Pará. Observações mensais foram feitas de 2006 a 2009. A maior incidência ocorreu no início do período chuvoso, em outubro e novembro, nos primeiros anos do plantio, quando diferentes intensidades de desfolha foram observadas. Embora danos significativos não tenham sido constatados, P. filippiniae tem potencial para causar prejuízos à cultura. Recomendam-se monitoramentos mensais nesse período e a catação manual do inseto para evitar maiores danos.
