Two yellow dent corn hyrids were inoculated with Aspergillus flavus and A. parasiticus and stored in static and aerated systems. Two fluorescences were observed under black light in the inoculated grain: bright greenish yellow (BGYF) and blue white (BWF). The incidence of these fluorescences varied with each isolate in relation to storage conditions. The A. parasiticus inoculated grain had more BWF than BGYF, whereas corn inoculated with A. flavus had similar amounts of both fluorescences. The correlation between the incidence of either the BGYF or BWF and aflatoxin in individual kernels was 74-80% for A. parasiticus, a good aflatoxin producer, but very low for A. flavus, a poor toxin producer. Aflatoxin occurred in 6.7 and 19.6% of the nonfluorescing kernels selected from the static and aerated tests, respectively.
