摘要：

摘 要：为了探明香蕉球茎象甲虫体挥发物的各种成分，采用固相微萃取技术（SPME）提取香蕉球茎象甲的虫体挥发物，进行气质联用仪（GC-MS）分析鉴定。结果表明：香蕉球茎象甲雌虫、雄虫、雌雄虫（雌虫和雄虫等数量混合）分别鉴定出9种、8种和9种成分，各占总峰面积的61.05%，39.46%和17.43%。香蕉球茎象甲雌虫、雄虫和雌雄虫三种虫体挥发物共有成分有3,7-二甲基-1,3,6-辛三烯、α-荜澄茄油烯、(1,1-二甲基乙基)-2-甲氧基苯酚、邻苯二甲酸二乙酯、3,3',5,5'-四甲基联苯和邻苯二甲酸二异丁酯6种，而3,7-二甲基-1,3,6-辛三烯是香蕉球茎象甲雌虫、雄虫和雌雄虫三种虫体挥发物中含量最高的成分，为19.15%。香蕉球茎象甲虫体挥发物各成分种类多样，相对含量差异较大。

Abstract: In order to investigate body volatiles of the banana corm weevil, Cosmopolites sordidus (Germar), solid-phase microextraction (SPME) was applied to trap body volatiles of C. sordidus, and the trapped body volatiles were analyzed using gas chromatography-mass spectrometry (GC-MS). The results showed that: there were 9, 8 and 9 body volatiles of C. sordidus females, males, females and males(females : males = 1:1), representing 61.05%, 39.46% and 17.43% of the total peak area, respectively. The same body volatiles were Ocimene, à-Cubebene, Phenol,(1.1-dimethylethyl)-2-methoxy-, 1,2-Benzenedicarboxylic acid diethyl ester, 3,3',5,5'-Tetramethylbiphenyl, Phthalic acid,diisobutyl ester, and relative content of Ocimene (19.15%) was the highest in three body volatiles. There were all kinds of constituents, and relative contents were significantly different in C. sordidus.
