Abstract

The coccinelid predators (Coccinella undecimpunctata and Coccinella sptempunctata) were more abundant species on the tested host plants than  Chrysoperla carnea and Eupeodes corolla (F) .The coccinelid predators greatly preferred white bean over cowpea and squash. However, the chrysopid predator, Chry. carnea greatly preferred white bean over squash and cowpea plants.  E. corolla (F) showed more preferability to cowpea than white bean or squash plants.
In respect to the preference of predators for their prey, Chrysoperla Carnea and E. corolla (F) greatly preferred aphids and whitefly over leafhopper. On contrary, coccinelid predators showed highest degrees of preference to leafhoppers and aphids than whitefly.
