<br/><br/> In Egypt bactrocera zonata caused considerable damage and inflicted significant economic losses in fruit orchards so that it is established as an economic pest . Investigation of the effect of gamma radiation on the expression of B. zonata DsX gene had been performed . Two days before eclosion mature pupae were irradiated at 100, 120 150 GY gamma radiation respectively as the effective recorded dose
