title: Pheromone emission by individual females of carnation tortrix,Cacoecimorpha pronubana.
abstract: The emission of five pheromone components by individualCacoecimorpha pronubana females was measured during 15-min sampling intervals. Pheromone was only released during female calling. Blend ratios emitted by individual females were constant over three calling periods, despite variations in release rates. Release ratios of the Δ11-componentsZ11-14∶Ac,E11-14∶Ac, andZ11-14∶OH were similar for all females tested, but release ratios of Z9-14∶Ac to the Δ 11-components showed significant interindividual variation.
