Cereals like other stored food are currently experiencing serious health problems during storage. The offending agents are primary pests such as Sitophilus oryzae and secondary pests among other (Tribolium.Sp). This study focused on the evaluation of the biocidal effect of the essential oils of thyme and made the citrus, against adults of red flour beetle (Tribolium castaneum) under different temperature regimes. The results of this study showed that different molecules have made a late effect (12h-14h-16h-18h) on the populations of Tribolium castaneum at the storage temperature of 20?C. The same results show an early striking effect of thymol and carvacrol on individuals Tribolium castaneum compared to limonene. The toxicity of thymol and carvacrol are much more active than limonene at 12h and exercises a very remarkable as limonene expresses its toxicity that from 14h deadly effect. Temperatures under 20?C and 25?C, thymol showed a greater degree of efficiency followed by carvacrol and limonene which has a low. However at 28?C, carvacrol expresses a very significant biocidal effect compared to the other two formulations thymol and limonene.
