Evaluation Of Ethiopian Isolates Of Entomogenous Fungi As Potential Biological Control Agent Of The Desert Locust Schistocerca Gregaria.

Ten native fungal isolates were collected from the different regions of Ethiopia. Eight of thernisolates were identified at International Institute of Tropical Agriculture, UTA, Benin. Five ofrnthe isolates were identified as Beallveria, two were Paecilomyces and one belonged tornMetarhizilllll species. Eight of the tested fungal isolates showed pathogenecity to fifth instarrnSchistocerca gregaria. The Beallveria spp. isolate FF and MetarhiziulII spp. EE were morernvirulent compared to the rest. Thus two isolates were further assayed in peanut (Arachisrnhypogaea) and noug (GlIizotia abyssinica) oil formulations, and compared with a knownrnentomopathogen, M anisopliae ICIPE 30. The results indicated that there were strong doseresponsernpatterns. Peanut oil formulation enhanced infectivity of both FF and EE. Infectivityrnof EE was significantly (P
