Five stored unprocessed cowpea (Vigna spp) and four groundnut (Arachis hypogeae) varieties available in Borno State were examined for the mould flora. The degree of infestation of the grains ranged from 31% to 100% and 68% to 86% for surface sterilized cowpea and groundnut respectively. The mould flora commonly encountered were species of the genera Aspergillus. Penicillium species, Scopulariopsis species and Trichoderma species were also found. The flora of the cowpea was dominated by Aspergillus niger while Aspergillus flavus was the dominant mould on groundnut.
