Extract

We reported previously (Steck et al. 1977) that equal-parts mixtures of (Z)-11-hexadecenal (Z11-16:Ald) and (Z)-11-hexadecenyl acetate (Z11-16:Ac) attract male Crymodes devastator (Brace) moths to field traps, and that attraction is enhanced by incorporation of (Z)-7-dodecenyl acetate (Z7-12:Ac) in the lure. During subsequent studies with sex lures for this species we discovered that (Z)-11-hexadecenol (Zll-16:OH) is much more effective than Z7-12:Ac as a trapping synergist.

During 1978 many structural analogs of the sex attractant components were tested as lure synergists by adding 20% of each analog to a basic 2:l Z11-16:Ald + Z11-16:Ac lure, using numbers of males trapped as the criterion of effect. Z5- and Z7-10:Ac; Z5-, Z7-, and Z9-12:Ac; Z5-, Z7-, Z9-, and Z11-14:Ac; Z5-, Z7-, and Z9-16:Ac were tested in this way, as were the corresponding alcohols and aldehydes and Zll-16:OH. The (E) isomers of these along with Ell-16:Ald and E11-16:Ac were finally tested.
