In: Mansoura University Journal of Plant Protection and Pathology 2011.v.2(6)Summary: The relative attractiveness of flowering plants to some aphidophagous species; predators (Syrphus corollae Fabricius, Chrysoperla camea Steph., Coccinella undecimpunctata L.and Paederus alfierii Koch ,and the parasitic wasp Aphidius sp. was evaluated under .laboratory conditions. Flowers included: coriander (Coriandrum sativum L) chamomile, (Matricaria chamomilla, ) geranium (Pelargonium graveolens Ait ) and Fennel ( Foeniculum vulgare .Miller ) sweet basil ( Ocimum basillicum, L, ). The obtained results revealed that the tested natural enemies exhibited different degrees of selectivity in response to olfactory stimulant produced by the flowers. Chamomile flowers exhibited higher attractiveness to the hoverflies (S. corollae) than to the other tested predators . Chry camea exposed to different flowers oduor showed the highest attractiveness to fennel followed by coriander with no significant differences.
