Abstract :AM1-type molecular orbital calculations were performed on the geometry-optimized struc-tures of various 4-insert ignore into journalissuearticles values(1`, 5` - dimethly -4` - heptenylidene); -1- methylcyclohexene isomers. It was found that the major component insert ignore into journalissuearticles values(4Z, 4`E isomer); of the sex pheromone of Eurygoaster integriceps is very dissimilar in chemical composition to the other isomers, although the stabilities and heats of the for-mation characteristics are comparable. However, some small molecules resembling only a part of the pheromone might exhibit some partial activity.
