Abstract
A mixture of Z -5-tetradecen-1-yl acetate and E -7-tetradecen-1-yl acetate in ratios of 1:99 to 11:89 were found through behavioral bioassays in the laboratory and field testing to be a specific attractant for the adult male army cutworm, Euxoa auxiliaris (Grote). The optimum ratio of these chemicals was about 5:95 and the pure chemicals alone were nonattractive in the field. The greatest trap catches were to 1 mg of attractant on rubber band dispensers and the males were only attracted during their 2nd flight period of August to October. The attractant was more effective in attracting males than one unmated female per trap. It was strongly inhibited by low percentages of Z 7-14:Ac or Z 7-14:OH.
