Aphid Species Colonizing Conifer, Juniper and Cedar Trees along Hungarian Motorways

Abstract

Survey of aphids on dicotyledonous herbaceous plants along the Hungarian highways on 33 sampling points revealed the presence of 14 aphid species on gymnosperm trees. The most frequent conifer species was: Pinus nigra J. F. Arnold 1785 (21 locations) followed by Pinus sylvestris L.1753, Picea abies (L.) H. Karst. (4 locations), Juniperus communis L. 1753 (3 locations) and Juniperus virginiana L. 1753 (1 location), Thuja occidentalis L.1753 (2 locations), Thuja plicata Donn ex D. Don (1 location). Eulachnus agilis (Kaltenbach, 1843) was the most frequently collected aphid species on Pinus nigra, followed by Cinara brauni Börner, 1940, Cinara schimitscheki Börner, 1940, Eulachnus rileyi (Williams, 1911) and Cinara acutirostris Hille Ris Lambers, 1956. The less frequent Cinara species was Cinara piniphila (Ratzeburg, 1844) which is a new record for the Hungarian fauna. Pinus sylvestris accommodated three aphid species: Cinara intermedia Pašek, 1954 was the most frequent, followed by Cinara pinea (Mordvilko, 1895) and Eulachnus agilis. Picea abies accommodated Cinara piceae, Cinara pruinosa (Hartig, 1841), Cinara piceicola (Cholodkovsky, 1896) and Sacchiphantes abietis L. 1758. Juniperus communis and J. virginiana most frequently hosted Cinara juniperi (De Geer, 1773). Eulachnus agilis occurred once on Juniperus communis. A single aphid species Cinara tujafilina was found on Thuja occidentalis and Thuja plicata.
