Abstract

Callosobruchus maculatus (Fab.) (Coleoptera: Chrysomelidae: Bruchinae) is the main pest of Vigna unguiculata (L.) Walp. during the grain storage period. This study aimed to report the occurrence of a natural enemy associated with C. maculatus in cowpea, in the semiarid region of the Rio Grande do Norte state, Brazil. For this, cowpea samples were collected and placed in closed plastic containers, where they remained until the emergence of adult insects. From the infested samples, adults of C. maculatus and of the Dinarmus basalis (Rondani) (Hymenoptera: Pteromalidae: Pteromalinae) parasitoid emerged. This is the first report of D. basalis parasitizing C. maculatus in the semiarid region of the Rio Grande do Norte state.

KEYWORDS: Cowpea, Bruchinae, Pteromalidae, biological control.
