ABSTRACT
The East Palaearctic seed beetle Bruchidius terrenus (Coleoptera: Chrysomelidae: Bruchinae) is recorded for the first time to the Bulgarian fauna. Larvae of the bruchid infest mature seeds of introduced mimosa Albizia julibrissin (Fabacea), an ornamental tree in many countries. The level of damage on seeds caused by bruchid larvae was examined.
