Abstract

Stored grain insects found in sorghum stored in the central production belt of Sudan and losses caused.

Abstract

Baited insect traps were used to survey and identify stored grain insects in the main grain production and storage area that stretches east-west in the central Sudan. Trogoderma granarium, Rhizopertha dominica, Oryzaephilus surinamensis, Oryzaephilus mercator, Tribolium castaneum, Tribolium confusum, Sitophilus oryzae, Cryptolestes ferrugineus, Sitotroga cerealella and Tenebroides mauritanicus were collected in the traps, and all were within the previously reported limits of the climatic factors favourable for their presence and increase. T. granarium and R. dominica, respectively ranked first and second in abundance in all sites. T. castaneum occupied the third rank, whereas T. mauritanicus ranked the least in mean numbers. The percentage losses of sorghum corresponded reasonably well with the mean numbers of insects in the different survey sites. Author's summary.
