The main objective of the present research was to determine the influence of gamma irradiations on wheat,the diet of the grain weevil,using as parameters of the longevity and reproduction of this insect.The doses of 60Coγ-rays applied to wheat grains were O(control),125,250,500,1000,2000,and 4000 Gy,at a dose rate of 3000 Gy per hour.The longevity,expressed as life-expectancy in days,and the reproduction expressed as the number of F1 adults,showed no differences up to the dose of 2000 Gy.The wheat irradiated with the dose of 4000 Gy induced a lower life-expectancy of the insects fed with irradiated wheat and a smaller number of insects of the F1 generation.
