Rubber Septa As Dispensers For The Fall Armyworm* Sex Attractant

Rubber septa were effective dispensers for the fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith), sex attractant (Z)-9-dodecen-l-ol acetate (29-12: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. Copyright.
