Abstract

Individual cereal aphids of the species Sitobion avenae (Fabricius) and S. fragariae (Walker) were differentiated by their peptidase electrophoretic banding patterns; S. avenae has three diagnostic isoenzyme bands (PEP-3 to -5), whereas S. fragariae has one (PEP-1). Over 90% of 5389 individuals of these two species, collected from the grass Dactylis glomerata within 50 km of Rothamsted over the course of several years, were S. fragariae. The importance of D. glomerata and other non-cereal Gramineae species as alternative summer and overwintering hosts for S. avenae is discussed in relation to this finding.
