Entomopathogenic fungi naturally associated with cowpea aphid, Aphis. craccivora were surveyed and identified. There were 18 fungal species infected cowpea aphid, on broad bean in winter and on cowpea in late spring and summer from December (2008) to December (2009). Five genera of entomopathogenic fungi were recorded for the first time associated with A. craccivora in Egypt. These genera were: Trichoderma longibrachiatum, Panadora neoaphidis, Batkoa major, Entomophthora planchoniana, and Coidiobolus obscurus.
