Abstract

The female gypsy moth Lymantria dispar produces a single-component sex pheromone, called (+)disparlure (2-methyl-7,8-epoxy-octadecane), for upwind attarction of conspecific males for mating. It was recently shown that a (+) disparlure analogue, 2-decyl-1-oxaspiro(2.2)pentane (OXP-01) is neither stimulatory nor attarctive by itself, but strongly decreases the male response to the pheromone and also inhibits its attractiveness when the two compounds are blended at a 1:1 ratio. Aim of the present work is to study the temporal decay patterns of the attractive effect of the 1:1 blend as compared to those of the single components, OXP-01 and (+)D.
