journal of kerbala university, Volume 11, Issue 3, Pages 10-17

The Onion fly Eumerus sp.{Diptera : Syrphidae } is considered one of the most important pest on onion in Iraq. So this study was carried to demonstate the posssibilty of using the sterile insect technique incombet this pest .
The data showed that the dose of 90 Gray caused complete sterility of females whereas , this dose at 105 Gray sterilized all males for study irradiated at 5 days old pupae.
The oviposition was noticed in the mating between irradiated males and untreated females in all doses used, but the eggs were not hatched to the dose of 105 Gray, while in mating between untreated males and irradiated females the oviposition was not observed at 90 Gray and higher.
Results also showed that all gamma rays have not effected on pupation percentage of larvae produced from hatched eggs of irradiated males and females for all doses , The results showed that all doses have no effect on adults emergence percentage or sex ratio of adults produced as first generation from all mating types.
