The effect of gamma ray on the adult stage of Tribolium castaneum Herbest. and essential amino acid of wheat's flour

Granary weevils and specially meal’s louse are one of the most important factors in destruction of granaries (meal), in both quality and quantity. To examine the efficiency of non-chemical ways against the Tribolium castaneum, the influence of various doses of gamma ray on adult insect was studied. The experienced insects were reared in controlled situation (temperature 271˚C, humidity 6510%, light period 8:16) and after gamma radiation, they were kept in the same mentioned situation. Due to the primary tests, the extent of experienced dose for growth period of young-adult and mature-adult insects were determinated. Then the gamma effects on the insects were studied. Young-adult and aged-adult insects exposed to amount of special dose death registered of observe after one day. The probit analysis showed that, the amount of killer-dose for 50 percent of their population in the young-adult and aged-adult levels were 1495.30 and 1671.64 Gy. In order word, shining of the 1671.64 Gy of gamma ray can destroy. They most resistant point in this insect’s life is the adult level that is controllable with 2400 dose against all level of life in this pest. To find the effect of radiation on meal quality, the quantity of necessary amino acid in meal before and after radiation was studied. Analysis the collected observations showed that radiation doesn’t have any negative influence on quantity of amino acid in meal and actually in helps to increase the quantity of phenylalanine acid considerably.
