Abstract: | Previously, (Z)-11-tetradecen-1-yl acetate was reported as the sex pheromone of the obliquebanded leafroller,Choristoneura rosaceana (Harris). A mixture of 92% (Z)-11-tetradecen-1-yl acetate and 8% (E)-tetradecen-1-yl acetate has been reported as an attractant for this insect. (E)-11-tetradecen-1-yl acetate and (Z)-11-tetradecen-1-ol have now been isolated and identified from female tip extracts and shown to be behaviorally active; in addition, there is some evidence for the presence of (E)-11-tetradecen-1-ol in these extracts. TheZ E ratio for both the acetates and the alcohols in these tip extracts was about 98 2; the proportion of alcohols was rather variable, but the acetates always predominated. Maximum trap catches fn the field during the course of this study were obtained with 5 mg of 95 5 (Z) (E)-11-tetradecen-1-yl acetates containing 0.5–10% (Z)-11-tetradecen-1-ol (approx. 1%Eisomer) in polyethylene caps. No evidence was found for the presence of (Z)-11-tetradecenal in female tip extracts, and this compound was found to be ineffective in increasing trap catches.Lepidoptera: Tortricidae: Tortricinae.This research was supported in part by the Rockefeller Foundation, and by NSF Grant No. GB-38020. |
