Treatment of one day old females (previtellogenic) of A. persicus with JHA (Admiral) showed a significant effect on viability of deposited eggs and on total mortality of post-embryonic stages. On the other hand, treatment of 3-days old females (vitellogenic) and 7-days old females (post-vitellogenic and ovulation) of A. persicus exhibited a highly significant effect on viability of eggs and on total mortality of post-embryonic stages (especially larval and younger nymphal instars).             The topical application of JHA (Admiral) in different doses to newly laid eggs        (0-1 h POP) of A. persicus has a highly significant effect on the development of treated eggs.  This was also true in case of dipping of egg masses in solution containing different doses of Admiral for 1 minute.  This effect increased by increasing the dose of the hormonal material.
