Abstract: 【Aim】 To explore the components of the alarm pheromone of Tyrophagus putrescentiae. 【Methods】 The extracts were extracted from T. putrescentiae mites with hexane. Biological activity of the extracts was assayed by observing the behavioral response of the mite to the extracts. The components of the extracts were identified by GC-MS. 【Results】 T. putrescentiae had intensive alarm response to the extracts, which consist of neryl formate, Z-citral, and E-citral based on GC-MS data. 【Conclusion】 This experiment proved the existence of alarm pheromone in T. putrescentiae and established the foundation for its further research.

Key words: Tyrophagus putrescentiae, alarm pheromone, behavioral response, neryl formate, Z-citral, E-citral
