Abstract

On the attractiveness of disparlure, the sex pheromone of the gipsy moth Porthetria dispar (Lepidoptera, Orgyidae) for males of Zanclognatha lunaris (Lepidoptera, Noctuidae).

Abstract

Disparlure, the sex pheromone of Lymantria dispar (L.) (Porthetria dispar), is known to attract males of L. monacha (L.) (P. monacha) and L. obfuscata (Wlk.) (P. obfuscata), and its attractiveness to males of Herminia lunalis (Scop.) (Zanclognatha lunalis) was therefore tested in a pine stand in the Altai region of the USSR. The sample of disparlure tested was synthesised according to previous procedures and contained 7% of the trans-isomer. The traps in which it was exposed are described. Males were caught over a period of 3 days, and the lowest attractive concentration was 10-6 g, but 10-5 or 10-4 g was better. No females of the species were attracted.
