New records of an alien aphid species Tinocallis (Sappocallis) takachihoensis from countries in central and northern Europe (Hemiptera, Aphididae, Calaphidinae)

Abstract

The aphid genus Tinocallis Matsumura, 1919 (Hemiptera: Aphididae: Calaphidinae) in central and northern Europe is reviewed; it includes four species. The first records of the Asian elm aphid Tinocallis takachihoensis Higuchi, 1972 are reported from the Czech Republic, Denmark, and Poland. The record in Denmark is the first in Scandinavia. Alate viviparous females and nymphs of T. takachihoensis were collected from Ulmus glabra “Pendula” (the Czech Republic and Poland) and from U. minor (Denmark) in 2017. Tinocallis takachihoensis is the fourth Tinocallis species to be recorded from Poland and together with two other species from the subgenus Sappocallis, T. nevskyi and T. saltans, is a species of alien origin. The alate viviparous females are reviewed and re-described and their affinities and distribution in central and northern Europe are discussed. A key to the European species of Tinocallis based on the characters of live and slide-mounted specimens is also given.

Review of Mesocallis Matsumura from China (Hemiptera, Aphididae), with one new species

“…Myzocallis carpinicola is recorded only on Carpinus. Additionally, M. alnicola infests both Alnus and Corylus, and M. sawashibae occurs on both Carpinus and Corylus (Lee et al 2018). Only M. pteleae infests plants in several different genera of Betulaceae (Alnus, Betula, Corylus, Carpinus, and Ostrya) (Holman 2009).…”

Phyllophages biotopic distribution in sparsely wooded regions plantations

“…This caused the disappearance of a number of organisms, a sharp decrease in the number of useful biota, the wide distribution of herbivorous arthropods that had no economic value before, a violation of regulatory mechanisms and the formation of a group of pests that was relatively small in terms of species, but well adapted to new ecological conditions [5][6][7]. The weakening of natural mechanisms led to the emergence of new more aggressive biotypes of harmful species [5][6][7][8][9][10].…”
