Abstract: In northern Cameroon, small holders stored their crops for long period in permanent granaries. According to their architecture, these granaries could be grouped in 7 prototypes. During storage in these granaries, to prevent loss of harvested crops due to attacks of insect pests, farmers have a relish for industrial or natural insecticides. These tools are introduced in the granary at the same time they fill it with crops. In the studied area, 17 industrials insecticides are currently used. They are from 4 chemical families: chlorinated hydrocarbons 57%; organophosphates 30%, carbamates, 12% and pyrethrynoids 12%. In the other hand, farmers also introduce plants in their granaries. An amount of 27 plants were identified they belong to 13 botanical families. The 2 most important are Poaceae with 6 species and Lamiaceae with 5 species. The northern part of Cameroon where the storage is fairly conducted is characterised by 67% of farmers using plants as protectant of stored grains, they use mostly bottle-shape granary where the storage can last without significant losses for 48 months.
