Novel aggregation pheromone, (1S,4R)-p-menth-2-en-1-ol, of the ambrosia beetle, Platypus quercivorus (Coleoptera: Platypodidae)

摘要

We identified an aggregation pheromone of Platypus quercivorus using volatiles from the boring frass of an unmated male. Gas chromatography - electroantennographic detector (GC-EAD) showed an BAD active component from the volatiles. GC - mass spectrometry (MS) data and comparison of the retention times of stereospecific synthetic compounds of the optical isomers on chiral GC column showed that the chemical structure of the BAD active component was (1S,4R)-/7-menth-2-en-l-ol (quercivorol). A field trapping tests using quercivorol and its optical isomer demonstrated that the quercivorol is main component of aggregation pheromone of P. quercivorus.
