Discovery of Heliothela wulfeniana (Scopoli, 1763) (Lepidoptera: Crambidae: Heliothelinae) in northwestern Russia by use of pheromone trapping

Abstract

The grass moth Heliothela wulfeniana (Scopoli, 1763) is found in northwestern Russia (Leningrad Region) for the first time, thus filling the geographical gap between Finland and Estonia, on one hand, and central European Russia, on the other hand. The moths were caught by traps baited with synthetic sex attractants for the diamondback moth, Plutella xylostella (Linnaeus, 1787), operating in the period from August 2 to September 6 on fields of cultivated Brassica crops. It seems highly possible that the main component of the H. wulfeniana sex attractant is Z-11-hexadecenal
