The relative attractiveness of some olfactory stimulant materials to the oriental hornet wasp, Vespa orientalis L. was evaluated under laboratory and field conditions. Olfactory stimulant materials included some volatile oils ( cinnamon, bananas, camphor and mint) and other natural materials (yeast, chicken litter,  asber fermented grapes and sugar syrup as control). The obtained results revealed that the oriental wasp exhibited different degrees of selectivity in response to the tested olfactory stimulant materials. V.orientalis adults exposed to different volatile oils showed the highest attractiveness to cinnamon followed by camphor and mint oils with significant differences. The waspsexhibited the lowest preferability to bananas. The present study indicated that the oriental hornet wasp exhibited significantly positive response to asber fermented grape and chicken litter   in  comparison with yeast and sugar syrup. So, asber fermented grape and chicken litter  successfully attracted the wasp; these materials can be used in monitoring populations of Vespa orientalis.   Traps baited with cinnamon oil proved to be good bio control agent  against the oriental wasps as they strongly attractive to  them.   The oriental wasps, V. orientalis population was considerably decreased in treated apiary in comparison with untreated one.  Therefore, cinnamon oil could be used against the oriental wasps in IPM programs.
