Abstract

In this study, we investigate the effects of two substerilizing doses 100 and 150 Gray (Gy) of gamma irradiation applied to Full grown pupae of the Black cutworm, Agrotis ipsilon (Hufngel). and/or plant extract, Conyza dioscorides (Barnoof) with two different solvents and applied to the resulting 5th-6th instar larvae in F1 generation on certain biological aspects and the energy budget. 

Data revealed that gamma irradiation when combined with the extract in most treatments significantly higher than the control of reproduction at all treatments (doses and concentrations).

Most of the treatments increased the values of developmental/day, larval duration and % survival were measured. These indices in the F1 progeny as compare to the control treatment, except, at the % survival it was decreased at all treatments. These values were more obvious in combination treatments compared to gamma irradiation or plant extract treatments each of them alone. 

The coefficient of metabolizable energy (C.M.E.) not affected at all treatments. The efficiency of storage of ingested energy [E.S.I.(E)] and the efficiency of storage of metabolizable energy [E.S.M.(E)] were between increasing and decreasing when the F1 progeny treated with plant extract alone or combined with the dose 100 Gy while it were significantly increased at all treatments when the dose 150 Gy combined with the plant extract. The results obtained were discussed in terms of their implications for the best substerilizing dose for the irradiation of parental male pupae of A. ipsilon combined with the dose 150 Gy.
