Abstract
Rubber septa were effective dispensers for the fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith), sex attractant (Z)‐9‐dodecen‐l‐ol acetate (Z9–12:AC). Trap captures of FAW were related to Dose with the highest numbers of males being captured in sticky traps baited with 5 and 10 mg Z9–12:AC/septum; the 10‐mg dosage gave catches of males comparable to traps baited with virgin females for up to 2 weeks. The addition of 2% (Z)‐9‐tetradecen‐l‐ol acetate (Z9–14:AC) to septa treated with Z9–12:AC had no significant effect on catches of FAW at any of the dosage levels. (Z)‐ll‐Hexa‐decen‐l‐ol acetate was also tested as a potential sex attractant for the FAW.
