Abstract:		"The volatile components emitted from two scale insects, Ceroplastes japonicus and Ceroplastes rubens, were identified using GC-MS analysis. The major volatile components of the solvent extract from C. japonicus were alpha-humulene (35.8%) and delta-cadinene (17.0%), while those of C. rubens were beta-selinene (10.3%) and beta-elemene (5.1%). In GC/olfactometry, linalool, butyric acid, 3-methylbutyric acid, 2-methylbutyric acid, and vanillin were identified as the odor-active components of the extract from C. japonicus, in addition to trace amounts of trans-4,5-epoxy-(2E)-decenal, 4-methyl-(3E)-hexenoic acid, and phenylacetic acid. With regard to C. rubens, trans-4,5-epoxy-(2E)-decenal, 3-methylbutyric acid, and phenylacetic acid were identified as the odor-active components. Besides, decan-1,4-olide (gamma-decalactone) with milky cherry-like note and 3-hydroxy-4,5-dimethylfuran-2(5H)-one (sotolone) with brown sugar-like note were also detected as the characteristic cherry-like sweet-and-sour note of these two scale insects.
