Abstract
Field testing of a large number of synthetic compounds and many combinations of them revealed that male moths of the pale western cutworm, Agrotis orthogonia Morrison, were attracted to combinations of Z-5-dodecen-1-yl acetate and Z-7-dodecen-1-yl acetate. The most satisfactory attractants were combinations of these two compounds in ratios of 1:2 to 1:5 at 10 to 25 μg/septum dispenser. The effect of the attractant was strongly inhibited by the addition of 21% Z-7-dodecen-1-ol.
