摘要: Two components of the San Jose scale sex pheromone had previously been identified as 7-methyl-3-methylene-7-octen-1-yl propanoate (I) and (Z)-3,7-dimethyl-2,7-octadien-1-yl (II). An isomer various homologs have subsequently synthesized tested in a greenhouse bioassay. TheE II (XI) was found to be attractive male scales. This compound has now isolated from airborne extracts virgin female The composition natural 48.5%, 46.7%, 4.8% I, II, XI, respectively. In field tests California New York, synthetic XI scales alone combination with I but there no obvious increase trap catch when isomers were present same ratio blend.
