F. Wongcorral et al., ABUNDANCE AND DISTRIBUTION OF INSECT IN STORED WHEAT-GRAIN IN SONORA,MEXICO, The Southwestern entomologist, 21(1), 1996, pp. 75-81
Twenty-three species of insects were recovered from commercial storage
facilities in Sonora, Mexico. The most common were lesser grain borer
, Rhyzopertha dominica Fab., and the red flour beetle, Tribolium casta
neum. Abundance was greatest in wheat stored on the ground and lowest
in semi-underground and country metal silos. Diversity was very high d
ue in part to the warm and dry climate; the highest incidence of pests
were in the Southern Region.
