Abstract
Two compounds were isolated as active components of the female sex pheromone of the peach fruit moth, C. niponensis. The major component was (Z)-7-eicosen-11-one, and the minor one, probably (Z)- or (E)-7-nonadecen-11-one. (Z)-7-Tricosen-11-one was isolated but it was not biologically active. (Z)- and (E)-isomers of 7-alken-11-ones of carbon numbers ranging from 17-23 were synthesized. Biological activity of synthetic (Z)-7-eicosen-11-one (compound A) and (Z)-7-nonadecen-11-one (compound B) as attractants for male moths was verified in the field. The activity was synergistically enhanced by mixing the 2 compounds in the ratio 20:1 for compound A to compound B.This publication has 2 references indexed in Scilit:
