Abstract: The sex-pheromone-gland extracts of female oriental armyworm Mythirnnaseparata Walker at calling period were individually analyzed with capillary GC and GC-Mstechniques. The suitable solvent was selected. Both extracting and detecting methods weredeveloped. The components, content and ratio in one gland extract were etermined. The individual variation of each component in the extracts was also discussed.

Key words: Mythimna separata Walker, sex pheromone, GC, GC-MS
