Abstract Ctenopseustis obliquana females collected from Christchurch were found to produce a mixture of (Z)-5-tetradecenyl acetate and tetradecyl acetate in their sex pheromone gland, in contrast toC. obliquana from Auckland which produce an 80∶20 mixture of (Z)-8-tetradecenyl acetate and (Z)-5-tetradecenyl acetate. This identification has been made on the basis of instrumental and chemical analyses. Antennae of maleC. obliquana from Christchurch gave a maximal electroantennogram response to (Z)-5-tetradecenyl acetate. A field trapping program in Christchurch using combinations of synthetic (Z)-5-tetradecenyl acetate and tetradecyl acetate caughtCtenopseustis males equally well if the latter chemical was present or absent. No males were caught in traps baited with the Auckland-type pheromone. In Alexandra,Ctenopseustis males were caught in traps baited with Auckland-type pheromone and not in traps baited with Christchurch-type pheromone. This phenomenon is ascribed to the existence of sibling species within the describedC. obliquana.
