| The evaluate relative sensibility of fifteen cultivars of graminaceous crops Sorghum (Giza-15, Dorado); Barley (Giza-132, Giza-123); Rice (Giza-181, Sakha-101); Maize (SC-10, SC-131); Wheat (Giza-171, Gimeza-11, Sakha-95, Miser-1, Sids-12, Shandweel-1 and Bani sweaf-5) against Sitophilus granarius L. two test (free choice and Non-choice) were conducted in the Research lab at 28±1 °C and 65±5% R.H. The result demonstrated that highly significant differences between various graminiaceous grains in their susceptibility against Sitophilus granarius L. infestation. In free choice, the lines were categorized into three categories i.e., Giza-15, Dorado, Giza-171, and Gemiza-11 were found to be greatest susceptible; Giza-123, Giza-181, Sakha-101; SC-131and Miser-1 were found to be less susceptible and shandweel-1 was no injury. Weight loss were categorized into three categories i.e., Giza-15 (71.31±3.01) followed by Dorado (61.55±6.47) were highly weight loss, Giza-181, Sakha-101, SC-131, Misr-1, Bani sweaf-5 found to be less weight loss, Shandweel-1 was no infestation. The result indicated that the adult who emerged in Giza-123, Giza-181, SC-10, SC-131, Bani sweaf-5 were found to be less, Sakha-101, Sids-12, Shandweel-1 were no adult emerged. In the non-choice test, the two varieties, Giza-15, Gimeza-11 Showed the highest percentage of infestation (44.0±3.27) and (48.0±3.27%), followed by Dorado (35.0±2.0%). The varieties Giza-123, Giza-181, SC131, Misr-1, Bani sweaf-5 were the least; Sakha-101, Sids-12, Shandweel-1 observed no infestation. The highest percentage weight losses were in Giza-15 (28.71±3.08) followed by Dorado (22.46±4.53), Giza-123, SC-10, SC131, Miser-1 and Bani sweaf-5 were the least loss. Sakha-101, Sids-12 and Shandweel-1 were no weight loss. No adult emerged observed in Shandweel-1. The least adult emerged recorded in Giza-181, Sakha-101, SC-131, Misr-1 and Bani sweaf-5. These details are important for host plant resistant breeding program for the plant breeder. | ||||
