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 α-humulene (35.8%) and δ-cadinene (17.0%), while those of C. rubens were β-selinene (10.3%) and β-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 (γ-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.

两种规模的昆虫(日本拟赤藻和日本拟赤藻)散发出的特征气味。
使用GC-MS分析鉴定了两种鳞状昆虫(日本蜡毛虫和日本蜡毛虫)释放的挥发性成分。从溶剂提取物的主要挥发性组分C.刺参是α-葎草烯(35.8%)和δ杜松烯(17.0%),而那些C.鲁是β芹子烯(10.3%)和β-榄(5.1% )。在GC /嗅觉,芳樟醇,丁酸,3-甲基丁酸,2-甲基丁酸,和香草醛被确定为从提取物中的气味活性组分C.刺参,除了痕量的反式-4,5-环氧-(2 E)-癸烯,4-甲基-(3 E)-己酸和苯乙酸。对于鲁氏梭菌,经鉴定反式-4,5-环氧-(2 E)-癸烯,3-甲基丁酸和苯乙酸是气味活性成分。此外,还检测到带有乳白色樱桃味的decan-1,4-olide(γ-十内酯)和带有黑糖样味的3-hydroxy-4,5-二甲基呋喃-2(5 H)-one(索托隆)。作为这两种昆虫的典型樱桃般的糖醋味。
