Argyrotaenia velutinana

Figure 3.6 Biosynthetic pathways for producing the intermediate CoA derivatives of the pheromone blend of the redbanded leaf roller moth, Argyrotaenia velutinana. The CoA derivatives followed by a superscript number in parentheses are reduced to an alcohol and acetylated to form the acetate esters that make up the pheromone blend. The superscript numbers indicate the approximate ratio of components found in the pheromone gland (Bjostad et al., 1985).

Z11-14 Acid and 11-14 Acid are the only unsaturated pheromone intermediates of the redbanded leafroller moth, Argyrotaenia velutinana (Bjostad and Roelofs, 1981). Stable isotope experiments showed that the mixture of these unsaturated...

One insect proved to be of special interest and was studied in greater detail (5-6). The redbanded leafroller moth (RBLR), Argyrotaenia velutinana, uses (Z)- and (E) -11—tetradecenyl acetates as pheromone components in the ratio of 9 1. The pheromone glands of these insects also contained the corresponding acids, All-tetradecenoic acids, but the Z to E ratio was about 4 5. If these acids serve as precursors to the acetates, there must be strict stereochemical control exercised in the reactions that produce the final product in the 9 1 ratio. 

Z)-l 1-Tetradecenyl acetate, which is the sex attractant of several insect pests of economical importance such as Ostrma nttbialis, Argyrotaenia velutinana and Choristoneura rosaceana, has been prepared in a similar way (Roelofs and Am, 1968 Roelofs and Tette, 1970 Klun and Brindley, 1970).
