Abstract

A collection of aphid parasites and hyperparasites (Hym.) from Iceland.

Abstract

As a result of collections of mummified aphids in Reykjavik and northern Iceland in 1975, 7 species of primary parasites and 5 species of hyperparasites of aphids were recorded, and it was found that the parasite fauna is of a predominantly boreal nature and closely related to that of northern Europe. Of the primary parasites, Aphidius picipes (Nees) (from Acyrthosiphon malvae (Mosley) and A. auctum (Wlk.) on various plants), which was the most abundant of the parasites taken, Aphidius ribis Hal. (from Cryptomyzus galeopsidis (Kalt.) on Ribes sp.), A. salicis Hal. (from Cavariella spp. on Salix sp.) and Aphelinus abdominalis (Dalm.) (from Ericaphis latifrons (Born.) (Fimbriaphis latifrons)) on Vaccinium uliginosum) were recorded for the first time in Iceland, and the hyperparasites Dendrocerus bicolor (Kieff.) (from Acyrthosiphon malvae parasitised by Aphidius picipes on Achillea millefolium) and Phaenoglyphis piciceps (Thoms.) (from parasitised Metopolophium festucae (Theo.) on Poa annua) are also new to Iceland.
