Sex pheromone of a conifer-feeding budworm,Choristoneura retiniana, Walsingham.

Journal of chemical ecology

Daterman GE, Cory HT, Sower LL, Daves GD.
PMID: 24318237
J Chem Ecol. 1984 Jan;10(1):153-60. doi: 10.1007/BF00987652.

Sex pheromone components collected from femaleChristoneura retiniana included 11-tetradecenyl acetates and alcohols. The major component wasE-11-tetradecenyl acetate (E11-14∶Ac) with a lesser amount ofZ isomer necessary to induce male response. A 92∶8 ratio ofE,Z11-14∶ Ac appeared optimal. The alcohol component...
