Abstract
Foraging behavior of some coccinellid predators (coccinella.Undecinpunctata L,, Coccinella septempunctata L. and Cydoina vicina isis L.) in response to different host plants (cowpea, white bean and broad bean) and prey species ( Aphis gossypii (Glover.) , Myzus persicae (Sultzer.) and Aphis fabae (Scop.) ) were evaluated under laboratory conditions. The lady beetles exhibited different searching rate and matual interferace values in response to differant host plant and prey species. However , the searching rate of C. undecimpunctata adults was higher on A.gossypii than on M. persicae and A. fabae especially those reread on cowpea plants. While, C.septumpunctata showed the higher searching rate on M. persicae than A. fabae and A. gossypii ,especially on white bean .On contrary, the highest searching rate of the black lady beetles was recorded on A. fabae and M. persicae reared on white bean (0.769, 0.701 )or broad bean ( 0.746, 0.708) in comparison with A. gossypii. The eleven spotted lady beetles recorded relatively higher mutual interference values in comparison with those of seven- spotted or black lady beetle adults, especially on cowpea plants . The present study revealed that the highest searching rate with relatively low mutual interference value for C. undecimpunctata (0.763, 1.881), C. septumpunctata (0.781, 1.626) and C. vicina isis (0.769, 1.684) were recorded on ( A. gossypii reared on cowpea ), (M. persicae reared on white bean) and (A. fabae reared on white bean ), respectively.
