Attraction ofCacoecimorpha pronubana male moths to synthetic sex pheromone blends in the wind tunnel.

Attraction ofCacoecimorpha pronubana male moths to blends of four sex pheromone components was studied in the wind tunnel.Z11-14∶Ac alone did not elicit upwind flight, admixture of 10%Z11-14∶OH or more led to successful attraction of males to the source. Attractivity of these binary blends was further enhanced by addition ofE11-14∶Ac orZ9-14∶Ac; the optimum was a blend ofZ11-14∶Ac,Z11-14∶OH,E11-14∶Ac, andZ9-14∶Ac at the proportion of 100∶30∶3∶3. In ternary and quaternary blends, the effect ofZ11-14∶OH andE11-14∶Ac was strongest at 30% and 3%, respectively. By contrast,Z9-14∶Ac increased behavioral responses over a wide range.
