Abstract
The southwestern pine tip moth, Rhyacionia neomexicana (Dyar), is a destructive pest of young ponderosa pine trees. Male moths are attracted to traps containing virgin females, but chromatographic fractions of female abdominal tips failed to entice males. A variety of synthetic materials were field tested at Chevelon, Arizona over a 6‐year period (1971–1976). (Z)‐7‐Dodecen‐l‐ol acetate, (E)‐7‐dodecen‐1‐ol acetate, and especially (E)‐9‐dodecen‐1‐ol acetate were attractive to the male moth. However, none of the synthetic compounds was as effective as live virgin females.
