Effect of Sitophilus oryzae infestation on Aspergillus flavus infection and aflatoxin contamination in stored wheat
1991
Sinha, K.K. | Sinha, A.K.
Moisture content, Aspergillus flavus infection, and aflatoxin production were investigated in 6.5 kg lots of wheat infested by Sitophilus oryzae and/or A. flavus at harvest and during 3 months storage in metal pots. The grain moisture content and A. flavus infection rates increased throughout the storage period and were greatest in wheat lots infested with both S. oryzae and A. flavus. Insect infestation correlated with increased aflatoxin production. Toxin producing strains of A. flavus were isolated from wheat grains and internally from the weevils.
