The increased activities in sesame production in the Sudan have led to an interest in studying the pests of economic importance of sesame crops. Four sesame varieties each contained about 50% oil averages were found significantly affected by the sesame seed bug. The influence on the quality and quantity of the sesame oil for domestic consumption and export was assessed. Five levels of infestation 0, 15, 30, 45 and 60 days were used. Results indicated that the highest crop loss was obtained with 60 days of infestation; the weight loss reached an average of 13% while the loss of oil content was almost 50% of the control. The free fatty acids assessed as oleic acid, reached an average of 20%, also the fatty acids were affected. The study showed clearly that the sesame seed bug is now becoming a serious problem and limiting considerably the production of sesame and it is though time to give more attention to the control of this bug by adopting special integrated pest management program in the Sudan.
