The present research was conducted under laboratory conditions at the ICA Experimental Station "Palmira", to evaluate the weight loss of stored corn grains by Sitotroga cerealella Olivier (Lepidoptera: Gelechiidae).
The results indicate that a single larva consumes during its cycle an average of 32.17 mg, that is, 7.55 o/o the average weight of an unattacked grain, which is less than the 10.1 o/o indicated by Gerberg and Goldheim (1957).
