Amorbia cuneana, A Pest of Avocados in California: Discovery of Sibling Species Through the Use of Pheromone
The most effective lure for male A. cuneana (Walsingham) in Orange, Ventura, and Riverside counties of California was previo usly found to be a 1:1 ratio of (E.E)-10, 12- and(E,Z)-10, 12-tetradecadien-1 -ol acetates. In subsequent field tests in San Diego and Santa Barbara counties, this lure was ineffective. Analys is of sex pheromone glands (SPG) of female A. cuneana from these two counties showed the EE:EZ ratio to be about 1:9 and synthetic lures of this composition were highly attractive in these areas. Analysis of the SPG of a number of fe males from both areas showed that there were three population types; tw o in the low ratio areas po ssessed 37 and 58% EZ, and the third in the high ratio areas possessed 89% EZ
