African populations are confronted with food security problems. These problems can only be solved through the proper functioning of agriculture. However, to achieve food self-sufficiency, this presupposes good conservation of agricultural production for consumption as and when needed. But post-harvest losses of cereals and legumes such as cowpea are still a major problem in Senegal. Most of the losses of cowpea are due to Callosobruchus maculatus, which is the best adapted species to the life of the stocks of this legume thanks to the observed imaginal polymorphism of this species. This study has for aim the morphometric characterization of the cowpea beetle in the different agro-ecological zones of Senegal in order to verify whether the spatial distribution has an impact on the morphology of the insect. This is based on a sample of cowpea previously infected with C. maculatus in the different agro-ecological zones of the study framework. The results revealed the existence of morphometric groups between some agro-ecological zones of the study framework, in particular between the Sylvo-pastoral zone and the high Casamance in the Eastern Senegal.
