Crymodes devastator

The sex attractant produced by the female clover cutworm, Scoto-gramma trifolii, is a mixture of (Z)-ll-hexadecenyl acetate and (Z)-ll-hexadecenol 288). A mixture of these two compounds containing about 10% Zll-16 OH has proved to be most attractive 289, 290) while 20—25% Z11-16 OH decreases the catch of males appreciably 290). Adult males of the glassy cutworm, Crymodes devastator, are attracted by traps baited with equal parts of (Z)-ll-hexadecenyl acetate, (Z)-ll-hexadecenal and (Z)-7-dodecenyl acetate 291). No other species were trapped by this mixture. The addition of small quantities of either (Z)-11-hexadecenol or (Z)-9-tetradecenyl acetate completely inhibited attrac-tancy in the field. As a result of field tests, Underhill et al. 292) have recently found that alkenals may be as important in lepidopteran sex attractants as the acetates and alcohols.
