Cereal grains are the major source of food for humans and most domesticated animals. In many developing countries like Algeria, overall post-harvest losses of cereals and legums of about 10–15% are fairly common. The study was conducted in Setif high plains in the north east of Algeria. The Setif region is one of the important areas for the production of cereal crops. The objective of this work was to survey the insects pests stored in different stored products in Setifian region. Using different methods: manual samples, traps, and probes have been used to determine the presence of insects and manual inspection, sieving, cracking-floatation and Berlese funnels are used at present to detect insects in grain. We recorded seven species (6 Coleoptera: Trogoderma granarium, Tribolium castaneum, Rhyzopertha dominica, Tribolium confusum, Sitophilus granarius, Tenebrio molitor and 1 Lepidoptera: Ephestia kuehnielle). The relative abundance of the different species was discussed. Trogoderma granarium was the dominant species (82,10%) of insect pests recorded from cereals grains. So, biological control on Trogoderma granarium is described. The stored conditions for these species are also discussed.
