This study was conducted to evaluate the susceptibility of eighteen Iraqi wheat varieties against the infestation of Khapra beetle Trogoderma granaruimnine Everts; nine varieties of durum wheat  Triticum turgidum  Desf. (Um Rabei, Aksad65, Cham3. Bakrajo-1, Semeto, Creso, Baghdad2, Zain Turk, Sardar), and nine varieties of bread wheat  T. aestivum L. (Jihan99, Azza, Cham6, Tamuz2, Adnaniya, Adana, Ibaa99, Azadi, and Abu-Ghraib) were selected. Results showed that the Abu-Ghraib and Azza varieties were the most resistant to infested by the beetles; the total of insect’s population reached 4.8, and 5 insects.100 g-1 of wheat, respectively. Growth rate of 0 and 0.1 insect/month-1, loss of weight grains of 1.6 and 1.9 %, and the decreasing germination of grains (4.81, and 0.6)% were recorded for both varieties, respectively. While var. Semeto was susceptible to the infestation; the insect population attained 1238.8 insects.100 g-1 of wheat with a growth rate of 82.3 insect/month-1; also the loss of weight grains was 58.5 % and the loss of germination of grains increased to 84.3%. To conclude, this study demonstrated that the durum wheat showed higher susceptibility than bread varieties.
