摘要

In Senegal, millet (<i><span style="font-family:Verdana;">Pennisetum</span></i><span style="font-family:Verdana;"> </span><i><span style="font-family:Verdana;">glaucum</span></i><span style="font-family:Verdana;"> (L.) R. Br.) and rice (</span><i><span style="font-family:Verdana;">Oryza</span></i><span style="font-family:Verdana;"> </span><i><span style="font-family:Verdana;">sativa</span></i><span style="font-family:Verdana;"> (L., 1753)) are the most widely consumed foods. This study is part of improving the conservation of these two cereals in Senegal by assessing the quantitative and qualitative losses caused by a lepidopteran, </span><i><span style="font-family:Verdana;">Corcyra</span></i><span style="font-family:Verdana;"> </span><i><span style="font-family:Verdana;">cephalonica</span></i><span style="font-family:Verdana;"> (Stainton) subservient to millet and rice stocks. For this purpose, samples of millet and rice from an area of the center of the groundnut basin (Diourbel) were collected, sterilized in the cold and infected with </span><i><span style="font-family:Verdana;">C.</span></i><span style="font-family:Verdana;"> </span><i><span style="font-family:Verdana;">cephalonica</span></i><span style="font-family:Verdana;"> eggs from the same locality. These infected samples were tracked during a development period of two successive generations. The samples were scrutinized before being infected and after a larval cycle of codling moth. The results showed that rice grains are richer in water (10.75% ± 0.4249%, on average) than millet (9.40% ± 0.3944%, on average) and the difference in rank is very significant (p-value </span><span style="font-family:Verdana;">= 0.0001 < 0.05). </span><span style="font-family:Verdana;">Moreover,</span><span style="font-family:Verdana;"> the attack percentage on millet grains is three times higher (36.31% ± 25.18%) than rice (12.95% ± 6.69%) with a</span><span style="font-family:Verdana;"> non-significant difference (p-value = 0.296 > 0.05</span><i><span style="font-fam
