The current study was aimed to determine the influence of millet and rice food substrates on the biological parameters of C. cephalonica, a pest of stored cereals. To achieve this objective, millet and rice grains were collected from the largest seed conditioning station in Senegal, precisely in the centre of the groundnut basin. The eggs from the female moths from this farm were used to carry out the necessary tests to study the development parameters of the grain-borne rice borer. The results obtained from our work show that the type of grain has an effect on the biological parameters of the insect. The average duration of the insect's development cycle is longer in millet grains than in rice grains. In addition, the type of food substrate has a significantly different effect on the parameters: duration of immature stages, size and longevity of adults. The size of the imago is significantly higher in millet grainsthan in rice grains.
