Characterization of the Aspergillus flavus population within an Illinois maize field.

An evaluation was made of the genotypic diversity (DNA fingerprinting) of 269 Aspergillus flavus strains, including subpopulations isolated from grain sampled at harvest from a maize field near Kilbourne, Illinois.  Eight A. flavus genotypes were isolated from grain samples harvested in different years (1988-1991).  Ninety-eight percent of the A. flavus genotypes produced sclerotia and 53% produced aflatoxin.  The high genotypic diversity recorded for each subpopulation (grain, maize insects, soil, air), in addition to a limited sample size, precluded any assessment of the relative importance of these subpopulations as sources of A. flavus infective inoculum.
