Abstract
The objective of this study was to determine the variation induced in elemental contents in the whole body tissues of male and female adults of Bactrocera zonata irradiated as 5-d-old pupae with 10, 30, 50, 70 or 90Gy. Analysis for the 11 elements; Mg, Mn, Si, P, S, Cl, K, Ca, Fe, Cu and Zn were made by energy dispersive X-ray analyzer by using EDX. The most dominant elements in unirradiated male and female adults were K followed by P, however Mg, Mn and Fe occupied the last order. The major elements in the irradiated male and female adults were P, S and K in all doses. Percentage of total heavy metals Copper + Zinc in irradiated males was lower than their controls. The lower percentage of heavy metals was noticed at doses of 50 and 70Gy (13.96% and 15.03%, respectively) compared with 35.14% in unirradiated males. The same case was shown when female adults irradiated as pupae with 10, 30 and 90Gy, the percentage of total heavy metals decreased from 17.12% in unirradiated females to 16.40%, 14.60% and 16.19% respectively.
