Abstract

New invasive phytophagous insects in woods and forest plantings of Donbass.

Abstract

The article presents information about 19 species of invasive phytophagous insects which were registered during the last 20 years on the territory of Donbass. Three species (Trichoferus campestris, Xyleborinus attenuatus and Anisandrus maiche) belong to the group of specialized xylophages, which can damage physiologically weakened trees and be technical pests. Monophagous and oligophagous species represent a larger group of invaders. Four species were associated with Robinia pseudoacacia: Obolodiplosis robiniae, Phyllonorycter robiniella, Parectopa robiniella and Nematus tibialis; two species with Gleditsia triacanthos: Dasineura gleditchiae and Megabruchidius dorsalis. Only one invasive species (Phloeosinus aubei) was found on the Cupressaceae plants (Juniperus virginiana, J. sabina, Thuja occidentalis). Pityogenes bistridentatus was associated with Pinus nigra pallasiana, Leptoglossus occidentalis with Pinus sylvestris, Exechesops foliatus with Acer tataricum and A. ginnala, Acanthoscelides pallidipennis with Amorpha sp., Monarthropalpus flavus with Buxus sempervirens, Lignyodes bischoffi with Fraxinus pennsylvanica, Bruchophagus sophorae with Sophora japonica, Cameraria ohridella with Aesculus hippocastanum, Aproceros leucopoda with Ulmus pumila. It was found, that neighboring invaders from European, Caucasian and Mediterranean fauna, which previously were limited by the range of host-plants are the main invasive phytophagous insects in forest plantations of Donbass in the end of the XX century. Distant invaders, which were transferred from North America (8 species), Southeast Asia (3 species) and Far East (3 species) form the faunistic basis of contemporary complex of invaders.
