Pemphigus saliciradicis ( Börner, 1950) 

This new Wrangel Island record is also a new record for Russia. The single alate female of Pemphigus saliciradicis  was collected in the southern part of the island, about 6 km from the sea shore, in a biotope with creeping willow, Salix glauca var. cordifolia (Pursh) Dorn  , and dwarf willow, S. phlebophylla Anderss.  ( Fig. 3View FIGURE 3). This species is also known from Europe—England ( Stroyan 1964), Finland ( Heie 1980), Sweden ( Heie 1980), Switzerland ( Börner 1950), Transcaucasia—Georgia ( Barjadze 2009), Iceland and Greenland ( Hille Ris Lambers 1952, 1955, as Pemphigus salicicola  ), Japan ( Aoki 1975), and possibly also California ( USA) ( Lange 1965) and Baffin Island ( Canada) ( Richards 1963, as P. groenlandicus  , see Blackman & Eastop 2019). Apparently, this species is anholocyclic on the roots of Salix  spp. in the greatest part of its range. Given the absence of the presumed primary host (the only known primary hosts of Pemphigus  species are Populus  species) on Wrangel Island, it seems likely that P. saliciradicis  is also anholocyclic there. Transitions to anholocyclic overwintering in the absence of their primary host have been documented in other northern aphids ( Stekolshchikov & Buga 2009, 2018; Stekolshchikov 2017). However, bearing in mind the very low winter temperatures on Wrangel Island (reaching -43°C ( Svatkov 1970)), the life cycle of P. saliciradicis  requires additional study.
