The composition of the aphid fauna of Fennoscandia and Denmark

摘要

A systematic, zoogeographical and ecological survey of the composition of the aphid faunas of Norway, Finland, Sweden and Denmark is given. A total of 634 species have been recorded, most of them of western Palearctic origin. Some species have their borders of distribution here, in several cases depending on the distribution of host plants. Some of the species are boreo-alpine and some others have recently been introduced from other continents.
