摘　　要：This study was conducted under Laboratory of Plant Protection Department, Faculty of Natural Resources and Environmental Studies, University of Kordofan, Elobeid in Sudan, during March-June 2015 to assess the effect of six treatments on germination of cowpea seeds infested by Callosobruchus chinensis Linn., a serious Coleoptera pest which damages cowpea seeds. The agents used were groundnut oil, wood ash, sand, neem leaves powder, Rabal leaves powder and hot pepper powder. In the lab bioassay, the results obtained due to the infestation by C. chinensis showed that there were highly significant differences （P 〉 0.01） in the number of holes per 100 cowpea seeds between the different treatments at intervals of one month, and up to the end of the storage period, the numbers of holes per 100 cowpea seeds were 44, 740, 859, 856, 841 and 892 holes in the treatments, respectively. The germination of seeds treated with groundnut oil was 60%, while it was zero for the other treatments. It was concluded that the groundnut oil made creamy coat on the seeds and prevented the development of eowpea beetle infestation. Hence, it can be used by farmers at local levels to protect seeds for cultivation.
