Aphids of the genus Dysaphis Börner (Homoptera, Aphididae) living on plants of the family polygonaceae

Aphid (Hemiptera: Aphididae) species of the South Marmara Region of Turkey including the first record of Dysaphis radicola meridialis Shaposhnikov, 1964 for the aphid fauna of Turkey

“…While the first males appear a few days later than gynoparae forms, the first oviparous females on leaves of Malus spp. were reported early September in Leningrad Province (Russian Federation) and in late October in the North Caucasus (Stekolshchikov, 2006). Comments.…”

“…On p. 1234, the account of Muscaphis escherichi (Börner) is somewhat misleading as it implies that the synonymy with M. drepanosiphoides (MacGillivray & Bradley) is fully established, and that populations previously known under that name on Sorbus have a much more restricted distribution than those on mosses. In fact spring populations on Sorbus occur throughout most of Europe and in North Korea and Canada, yet all attempts at transfer of alatae from Sorbus to mosses have failed other than that by Stekolshchikov & Shaposhnikov (1993), who obtained limited success in transfers to Plagiothecium laetum, and gynoparae and males have never been collected from mosses. Molecular work is needed to determine whether the anholocyclic moss-feeding populations in Europe are isolated genetically from the Sorbusfeeding generations, in which case they should perhaps continue to be regarded as a separate species.…”

Large-scale geography survey provides insights into the colonization history of a major aphid pest on its cultivated apple host in Europe, North America and North Africa

“…Alternatively, D. plantaginea may have originated in the Caucasus or Asia Minor, maybe through a host jump from Pyrus to Malus . Dysaphis plantaginea, Dysaphis radicola, Dysaphis devecta, Dysaphis brancoi , Dysaphis anthrisci, Dysaphis chaerophylli are Dysaphis species reported to feed on the cultivated apple, M. domestica, as their primary host (Blommers et al, 2004; Stekolshchikov, 2006), but many aphid species also feed on pears including, Dysaphis reaumuri Mordvilko and Dysaphis pyri Boyer de Fonscolombe (Barbagallo, Cocuzza, Cravedi, & Komazaki, 2007). The Pyrus genus is known to have diverged a long time ago from the genus Malus probably in the Caucasus (Celton et al, 2009; Xiang et al, 2017).…”

“…Furthermore, a lack of records of this species in the Global Biodiversity Information Facility (GBIF, 2020) also casts doubt as to whether D. plantaginea is common in this area. (Blommers et al, 2004;Stekolshchikov, 2006), but many aphid species also feed on pears including, Dysaphis reaumuri Mordvilko and Dysaphis pyri Boyer de Fonscolombe is Pyrus L. (Barbagallo, Cocuzza, Cravedi, & Komazaki, 2007). The Pyrus genus is known to have diverged a long time ago from the genus Malus probably in the Caucasus (Celton et al, 2009;Xiang et al, 2017).…”
