RESUMO
Euetheola humilis (Burmeister) is a scarabaeid pest of rice, sugarcane and corn cultures, that attacks the crops during both larval and adult phase. The occurrence of E. humilis was observed in a forest area with Eucalyptus saligna Smith, from Votorantim Celulose & Papel (Fazenda Aroeira), in the Municipality of Candiota, Rio Grande do Sul State. Plants approximately 1m high were damaged by E. humilis adult insects near the stem base, what unraveled its cortex and led some of them to death. The attack was verified in about 10% of the eucalypts plants, in an area of approximately 30 ha.

Euetheola humilis (Burmeister) é um escarabeídeo praga das culturas do arroz, cana-de-açucar e milho, que ataca as cultura na fase larval e na adulta. A ocorrência de E. humilis foi observada em área florestada com Eucalyptus saligna Smith, pertencente a Votorantim Celulose & Papel (Fazenda Aroeira), no município de Candiota, RS. Plantas de aproximadamente 1m de altura foram danificadas por insetos adultos de E. humilis na região próxima ao colo, desfiando seu córtex, levando algumas à morte. Verificou-se ataque em torno de 10 por cento das plantas de eucalipto, em uma área de aproximadamente 30 ha.
