Abstract

Electrophysiological techniques and behavioural assays were used to determine the response of males of Globodera rostochiensis to 4 fractions of the homospecific sex pheromone from virgin females, separated using reverse-phase high-pressure liquid chromatography. Sex pheromone activity was confined to 2 of the fractions. The sex pheromone of G. rostochiensis appears to be composed of several weakly basic, polar compounds.
