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.
