abstract
Effect of gamma radiation on the whole body contents of fatty and amino acids were investigated for peach fruit fly, Bactrocera zonata. The statistical analysis of the data indicated that the quantities of fatty and amino acids in the whole body of the adults of B. zonata were affected significantly. Data obtained indicated that the free fatty acids decreased when males irradiated with substerilizing dose 70Gy while increased in the sterilizing dose 90Gy in comparing to unirradiated males. In case of female the total fatty acids were increased by increasing dose of gamma radiation, Female showed higher total fatty acids contents than males. The irradiated males and females have maintained higher free amino acids content than the unirradiated once except male irradiated with 70Gy. Amino acid content in the resulting flies from irradiated pupae is greatly affected in all acids in males and females.
