【 摘 要 】

Preliminary notes about seasonal fluctuations of destructive insects of stored mil in traditional storehouses in Senegal. Insect flight populations infesting traditional millet storage have been followed by sticky trap during fifteen months in Senegal. Distribution analysis of species show that Sitotroga cerealella Oliv. (52 %) of insect total number is most abundant, following by Ephestia cautella WLK. (7V, 6 %), Tribolium castaneum Herbst. (17, 4 % o), Cryptolestes sp. (10, 1 % o) and Rhyzopertha dominica F. (9, 9 %>). Infestation has been discussed in relation between storage methodology. Relation between seasonal fluctuation of S. cerealella and several abiotic factors of ecosystem has been found.
