Abstract
The depth of infestation of stored wheat, maize and sorghum by Sitotroga cerealella (Ol.) was investigated in the laboratory in Nigeria using columns of grain 4.8 cm in diameter to simulate bulk storage conditions. Infestation was started by the artificial placement of eggs (80 on maize and 120 on wheat and sorghum) and, in other replicates, by exposure to 4 pairs of adults. After 10 weeks at 25°C and 70% RH, counts of damaged grains at various levels showed that the depth of infestation of maize (12 cm) was twice that of sorghum or wheat. Infestation decreased with depth on all grains, but the pattern of penetration differed between the 3 grain types
