Seasonal development of entomophthoralean unfection in colonies of Diuraphis noxia and Rhopalosiphum maidis was evalauted on summer barley under conditions of south-western Slovakia in 2001 and 2002. D. noxia was infesting summer barley during both years, while R. maidis was only recorded in 2002. Further three cereal aphids, Rhopalosiphum padi , Metopolophium dirhodum and Sitobion avenae , were also observed on summer barley. Complex of entomophthoralean fungi identified in cereal aphid colonies included four species, Pandora neoaphidis , Entomophthora planchoniana , Conidiobolus obscurus and Neozygites fresenii , with P. neoaphidis as the most prevalent fungus during both years. Two parasitic fungi, P. neoaphidis and E. planchoniana , were identified from D. noxia , but P. neoaphidis was predominant. Infection rate in D. noxia colonies was low, not exceeding 15% and 10% in 2001 and 2002, respectively. Only nine R. maidis individuals were killed with entomophthoralean fungi. The fungi were identified as P. neoaphidis and C. obscurus . No epizootics were observed in the aphid colonies. The fungi could not control development of the aphid populations since they did not appear until high host densities had been established in the crops.
