1 Chemical analyses of solvent extracts of pheromone glands of female western yellowstriped armyworm moths Spodoptera praefica (Grote) indicated the presence of (Z)-7-dodecenol (Z)-7-dodecenyl acetate (Z)-9-dodecenyl acetate (Z)-9-tetradecenyl acetate and (Z)-11-hexadecenyl acetate.

2 In field tests of combinations of these chemicals, small numbers of male S. praefica were captured in traps baited with (Z)-7-dodecenyl acetate. Numbers of males captured in traps were greatly increased in response to blends that included both (Z)-7-dodecenyl acetate with either (Z)-9-tetradecenyl acetate (Z)-9-dodecenyl acetate. The combination of (Z)-7-dodecenyl acetate and (Z)-9-tetradecenyl acetate provided the strongest sex attractant for use in trapping male S. praefica.

3 Males of the cabbage looper Trichoplusia ni (Hübner) were captured in traps baited with blends possessing (Z)-7-dodecenyl acetate, and were greatly reduced in traps baited with blends that included (Z)-7-dodecenol.

4 Multi-component blends that included (Z)-7-dodecenol attracted males of the alfalfa looper Autographa californica (Speyer).

5 Males of Peridroma saucia (Hübner) and Mamestra configurata Walker were captured in traps that included (Z)-9-tetradecenyl acetate with (Z)-11-hexadecenyl acetate.

6 These responses by other species of moths to S. praefica pheromone components and blends may still complicate the use of any lure for S. praefica.
