Aspergillus flavus infection and aflatoxin contamination of preharvest maize in Benin.

Eighty and 60 maize fields in Benin were sampled in 1994 and 1995, respectively, to monitor Aspergillus infection and aflatoxin contamination of preharvest maize.  Aspergillus flavus was the most prevalent species isolated.  The mean percentage of kernel infection was about 20% in both years.  Aflatoxin was extracted from maize in at least 30% of the fields sampled.  Damage by the ear borer,  Mussudia nigrivenella, increased aflatoxin accumulation in maize.  Hence, the geographic pattern observed in the occurrence of A. flavus and aflatoxin may be related to the incidence of M. nigrivenella.
