Seasonal incidence of entomopathogenic fungi infecting cereal aphids of wheat plants in Assiut, Egypt [electronic resource].

Includes reference.

The present investigation was carried out during two successive wheat growing seasons (2002/2003 and 200312004). The seasonal incidence of entomopathogenic fungi infecting cereal aphids was evaluated. Regardless of the aphid host and the season, the present results indicated that various entomopathogenic fungi caused aphid mycoses. The incidence of each pathogen or pathogen group was estimated from 2100 cadavers of three aphid species examined microscopically during 2003 and 2004 wheat growing seasons. There are twelve identified species of entomopathogenic fungi,infecting cereal aphids. The first case of mycosis was observed at the beginning of February. In addition, the number of diseased aphids increased towards end of March.
