Kordofan is considered as one of the most important areas in Sudan for producing leguminous seeds. Bruchids are the most important pests that are responsible for damage in stored and forest leguminous seeds. This study was conducted with the objectives of seeing the variations and their host associations in Kordofan. Field and laboratory investigations targeting the distribution and abundance of bruchids and the qualitative and quantitative losses caused by them. Field surveys were done. Weight loss/100 in Hashab seeds was 0.17%. Mesquite seeds did not host of C. chinensis in the laboratory. The total weight loss and number of holes/100 seeds in Hashab seeds were 3.75, respectively. The germination percentage of Hashab seeds was found to be 60% in the control. Finally, this study makes available data on the range differences among family Bruchidae and their host associations, which may pave the way for ecologically sound management in the future. This study recommended significant care toward these pests due to their economic effect with regard to hashab trees and other forest tree species.
