Resumo

The ecological station of Cuniã (ESEC Cuniã) was created in order to avoid the loss of biodiversity at the Purús-Madeira interfluvium, where the re-asphalting of BR-319 facilitated access to the region causing an excessive exploitation of its natural resources. To contribute with the purpose of legal biological reserves, it is now necessary to explore the biodiversity within this area, such as parasitoid hymenopterans of the Braconidae family, which can be used as indicators of the arthropod diversity. Therefore, the present work aimed to carry out a survey of the Braconidae genera in the ESEC of Cuniã. Sampling were carried out in the PPBio grid, an area of 25 km², using Malaise traps, in the years of 2011 and 2012, totaling 4 collection events. A total of 360 specimens were collected, identified in 18 subfamilies and 69 genera. Six subfamilies and 36 genera are new records for Rondônia. The subfamilies with the greatest genus richness were Microgastrinae (17) and Doryctinae (12), while the most abundant genera were Heterospilus Haliday (39), Bracon Fabricius (22), Rogas Nees (16) and Chelonus Panzer (15). General diversity of subfamilies and genera was similar to other Brazilian regions, suggesting a rich diversity of Braconidae at ESEC of Cuniã. Moreover, some genera found has potential use for future biological control programs.
