| 中文摘要: |
| 采用Y型嗅觉仪测定了西柚对桔小实蝇(Bactrocera dorsalis)雌虫的引诱活性。同时采用固相微萃取技术（Solid Phase Microextraction,SPME）对西柚挥发性物质进行收集，并运用气相色谱－质谱联用技术（GC-MS）对西柚挥发物化学成分进行了分析。结果表明，西柚对桔小实蝇雌虫具有明显的引诱作用。西柚挥发物主要成分为烯类物质，其中含量大于5%的物质为柠檬烯（45.52%）、月桂烯（4.09%）、α-蒎烯（1.28%）、反式石竹烯（0.64%）和萜品油烯（0.61%）等5种烯类物质。推测这些物质可能是西柚引诱桔小实蝇雌虫的主要活性成分。 |
| 英文摘要: |
| The attractive activity of grapefruit to B.dorsalis was studied by Y-tube olfactometer in laboratory. The volatile components of grapefruit were extracted by solid phase microextraction (SPME) and analyzed by gas chromatographic-mass spectrometric (GC-MS).The results showed that grapefruit possessedsignificant attractive effect on B.dorsalis. The main components of the volatile compounds of grapefruit were alkene compounds.The content of which is greater than 5% was D-Limonene（45.52%）、Myrcene（4.09%）、(1R)-( )-a-pinene（1.28%）、Caryophyllene（0.64%）and Terpinolene（0.61%). So, it was speculated that these compounds possibly are active components. |
