Abstract

Dioclea violacea seeds were collected at Fazenda Santo Antonio, Pacatuba, Sergipe, northeastern Brazil, to produce seedlings for recovery purposes in degraded areas. In the field, 163 seeds were collected and sent to the Forest Entomology Laboratory, Department of Forest Sciences of the Federal University of Sergipe, for processing. In some of the seeds, perforations and/or dark round spots were observed indicating the presence of beetles in the seeds. Based on morphological characteristics, the beetles were identified as Caryedes brasiliensis. In its adult stage, C. brasiliensis feeds on pollen, unlike the larvae that feed on the seed cotyledon. This is thought to be the first record of C. brasiliensis causing damage to the seeds of D. violacea in Brazil.
