The powder post beetle, Lyctus linearis Goeze, is the member of wood-boring beetles group which belong to family bostrichidae and consider the main cause of the low value and degradation of quality properties of manufactured wood products.      The results indicated that chosen artificial diet has consisted of white corn flour (75%), sawdust (15%), dried yeast (5%), sugar (3.5%) and ascorbic acid (1.5%). This artificial medium revealed clear differences in biological activities and was more suitable from natural host to rearing Lyctus linearis beetle for made different investigation studies.       Egg incubation period, larval duration, pupal duration, hardness period and the total period of developmental stages were short-lived in artificial diet, while the number of laid eggs by the female was more in comparison natural host. The statistical analysis showed highly significant negative correlation between the temperature and each the different development stages while; the relative humidity gave positive significant correlation with some different developmental stages.       Five annual generations were obtained from rearing the beetles on the artificial medium diet.  The shortest generation recorded 6 weeks (2^nd generation), while the longest generation recorded 16 weeks (5^th generation).
