Abstract

Bruchines damage agricultural crops and trees, reducing the quantity and quality of the seeds. The aim of this study is to record, for the first time, Paracrias pluteus as a parasitoid on the immature stages of Sennius spodiogaster and Sennius cupreatus on seeds of Melanoxylon brauna in Teixeiras, Minas Gerais State, Brazil. Paracrias pluteus is a parasitoid without previous host records and known only from Costa Rica. Specimens obtained in this study add to knowledge of the biology of Paracrias species with a new host group (Chrysomelidae: Bruchinae), and the first host record and a new distribution for Paracrias pluteus.
