The susceptibility of verieties of carrot to attack by the aphid, Cavariella aegopodii (Scop.)

The article contains new data on the Aphidoidea of Wrangel Island collected in 2015. Previously, at least four species were known. Two of them, Aphis polaris Stekolshchikov et Khruleva, 2014 and Metopolophium sabihae Prior, 1976, were regularly observed on the island in the 1980s and 1990s. Pterocomma groenlandicum Hille Ris Lambers, 1952 and Myzus (Nectarosiphon) polaris Hille Ris Lambers, 1952, were first collected in 2006. In 2015 three more species were found: Brachycaudus (Mordvilkomemor) rumexicolens (Patch, 1917), Cavariella aegopodii (Scopoli, 1763), and Pemphigus saliciradicis (Börner, 1950). This last species represents a first record for the territory of Russia whereas C. aegopodii had not previously been collected in tundra landscapes. In 2015, a total of seven aphid species were collected. For one of the four previously noted species, M. sabihae, a sharp increase in its abundance is recorded. We propose that the increase in aphid species diversity is due to climate warming in the Russian High Arctic. A detailed redescription of the oviparous female of P. groenlandicum is also provided.

Winged Aphid

Information about the seasonal occurrence and peaks of activity of winged aphid species was obtained by trapping during a period of 15 months at three locations within 45 miles of Melbourne. Most species were caught in greatest numbers during either the spring or the autumn. Species such as Myzus persicae (Sulz.) and Brevicoryne brassicae (L.) were caught throughout the year. Cavariella aegopodii (Scop.) was trapped only in cool weather, while Aploneura lentisci (Pass.) was caught only in warm weather. Water-filled yellow trays were very efficient for trapping many species, but a wind-vane sticky trap caught more of some species, including the grass-feeding aphids, than did the yellow tray.
