A study was conducted for screening of ten different irrigated wheat varieties against Angoumois grain moth, Sitotroga cerealella (Olivier) under laboratory conditions (28±2C°, 60±5% RH, 12:12 L:D hours) during 2009 at The University of Agriculture, Peshawar-Pakistan. The varieties were evaluated on the basis of developmental period, total progeny of S. cerealella and percent grain damage, percent weight loss, grain size and chemical composition of the grains. The results revealed that none of the varieties was completely immune to the attack of S. cerealella. However, their response varied significantly (P< 0.05). Weight loss being main index of resistance, variety Fakhre Sarhad (3.87% weight loss) was found significantly tolerant followed by Uqab (7.610%), Sehar (7.78%), Shafaq (9.19%) and Dera-98 (9.24%) while Pirsabak-2004 (13.39%), Pirsabak-2005 (13.82%), Raj (14.10%), Saleem-2000 (14.44%) and Pirsabak-2008 (27.75%) were significantly susceptible. The coefficient of correlation between percent weight loss and fat was negative and non-significant (r = - 0.215). The correlation of percent weight loss with protein content was negative and highly significant(r = - 0.632), while it was positive and highly significant with moisture (r = 0.690) and crude fibre (r = 0.649).
