In Ohio, modified Wong traps captured significant numbers of black cutworm males when baited with (Z)-7-dodecen-1-yl acetate (I) and (Z)-9-tetradecen-1-yl acetate (II) emitted either from glass capillaries (3: 1 mixture of I and II), rubber septa (30 μg of I + 10 μg of II), or a Hercon® multilayered polymeric dispenser. The best Hercon® dispenser was formulated with a 3:1 mixture of I and II at 390 μg/6.45 cm2; the optimum size was 12.90 cm2with a total exposed edge (the site of release) of 15.24 cm. Relatively low trap catches were recorded in traps baited with selected Conrel® fiber formulations.
