Effect of insect damage to maize ears, with special reference to Mussidia nigrivenella (Lepidoptera, Pyralidae), on Aspergillus flavus (Deuteromycetes, Monoliales) infection and aflatoxin production in maize before harvest in the Republic of Benin.

Maize infection by Aspergillus flavus and subsequent aflatoxin contamination as affected by insect damage to maize ears before harvest was studied with surveys in farmers’ fields and in a field trial in the Republic of Benin, West Africa. The most important pest species was the lepidopteran earborer Mussidia nigrivenella Ragonot. Percentage of grain infected by Aspergillus flavus and of samples, contaminated with aflatoxin, as well as the mean aflatoxin content of samples, increased with increasing borer damage. Artificial infestation with M.nigrivenella larvae increased aflatoxin content of maize by an average of 45mg/kg, whereas inoculation with A. flavus spores increased the toxin level by 517mg/kg.
