| abstract |
The present invention provides mainly (3Z,6Z)-cis-9,10-epoxy-1,3,6-heneicosatriene (formula 1) and (3Z,6Z)-cis-9,10-epoxy-1,3,6-eicosatriene (formula 2) which are Hyphantria cunea sex pheromones; therefore this inventors have succeeded in the invention which provides attractant components having high attraction effect for Hyphantria cunea, that is, Hyphantria cunea sex pheromones having high attraction activity and the intermediates which can selectively synthesize such pheromones with great ease. Furthermore, the present inventors have succeeded in the invention which provides attractant compositions with high attraction effect for Hyphantria cunea include such above pheromones and the known Hyphantria cunea sex pheromones. Consequently, this invention is completed. ( formula 1) ( formula 2) |
