Abstract
The occurrence, distribution, and biology of various cereal and grass aphids were noted in New Brunswick during 1960. Because of the similarity of Rhopalosiphum padi (L.) overwintering on Pruneae, and R. fitchii (Sanderson) hibernating on Pomeae, summer forms of these aphids are referred to as the R. padi-fitchii complex. An aphid from Phleum pratense L., very similar and closely related to Schizaphis graminum (Rondani), is described as S. graminum phlei ssp. n. Circumstantial evidence indicates that early spring migrants of Rhopalosiphum maidis (Fitch) and Macrosiphum avenue (Fabricius) did not originate in the province.
