TWO NEW MACROSIPHINI (HOMOPTERA: APHIDIDAE) FROM MANITOBA
The Canadian Entomologist, 1973AbstractTwo new species of aphids are described from Manitoba, Acyrthosiphon assiniboinensis new species from Potentilla fruticosa L., and Masonaphis pinawae new species from Ledum groenlandicum Oeder.

Abstract The large raspberry aphid, Amphorophora idaei , has several biotypes described by their abilities to overcome plant resistance genes. Bioassays of field populations showed a strong shift towards A, resistance‐breaking biotypes since the 1960s.

Miyazakia, a new aphid genus from Japan (Hemiptera: Aphididae: Macrosiphini)
Zootaxa, 2014Miyazakia gen. nov. with type species Miyazakia ranunculi (Miyazaki, 1971) comb. nov. is described. The species is illustrated and biometric data are provided for all morphs, except the fundatrix. This aphid genus is closely related to Sappaphis Matsumura, 1919. M.

The aphid tribe Macrosiphini Wilson, 1910 (Hemiptera: Aphididae: Aphidinae) is one of the most controversial groups within Aphididae. We sequenced 2876 bp from one nuclear gene (EF-1α) and four mitochondrial genes (COI, tRNA + COII, 16S) from 107 terminal taxa representing 57 genera of Macrosiphini s.l.

Present article deals with the food plants of the species of Sitobion genus (Aphididae: Hemiptera) in India. Total 26 species of the genus Sitobion are recorded, out of which almost half of them are monophagous feeding on one or two plant species belonging to one or two families. Six species are polyphagous feeding on 12 to 81 plant species.

Blanchardaphis was erected for two Argentinian species of aphids very similar to Uroleucon, but distinguished by several characters. Here, we examined morphology and DNA sequences of Blanchardaphis specimens from Argentina and Chile. We further conducted a phylogenetic analysis to determine the relationship of Blanchardaphis to Uroleucon.

A new genus and species of tribe Macrosiphini (Hemiptera, Aphididae) from northeast China
Zootaxa, 2008Brevisiphonaphis hirsutissima gen. nov., sp. nov. is described from specimens collected in northeast China on Artemisia argyi H.Lév. & Vaniot (Asteraceae). The genus is illustrated with the biometric data for apterous viviparous females. This aphid genus is closely related to Microsiphum Cholodkovsky, 1902 and Microsiphoniella Hille Ris Lambers ...

Lipaphis (Lipaphis) erdemi sp. nov. is described from apterous and alatae viviparous females collected in Central Anatolia (Türkiye) on Sisymbrium sp. (Brassicaceae). The new species is markedly different from the other species of the subgenus Lipaphis by having secondary rhinaria on the antennal segments III, IV and frequently V in apterous viviparous

AbstractWe performed molecular and morphological analyses to determine the generic limit of the genusAulacorthum, including several species with controversial taxonomic histories. The sequences of four mitochondrial genes,COI,COII,srRNAandlrRNA, and one nuclear gene,EF1a, implied thatAulacorthumis not monophyletic, withAulacorthum ...

BLANCHARDIA POIKILA GEN.NOV., SP.NOV. (HEMIPTERA: APHIDIDAE, MACROSIPHINI) IN MENDOZA, ARGENTINA
The Canadian Entomologist, 1997AbstractBlanchardia gen.nov. and its type species Blanchardia poikila sp.nov. are described and the new combination Blanchardia capitophoroides is established for Macrosiphum capitophoroides Blanchard, 1944. The new genus forms part of the Macrosiphum group and it is characterized by the presence of one to three poorly defined rows of cells on the apex
