A Male Aggregation Pheromone in the Bronze Bug, Thaumastocoris peregrinus (Thaumastocoridae)

Figure 1

GC-MS traces (TIC) of T. peregrinus male (top) and female (bottom) volatile extracts analyzed in a polar column. A male-specific compound was present in male volatile extracts, with a retention time of 10.1 min (mass spectrum shown in insert (a)). A coeluting compound in female volatile extracts was identified as nonanal based on its mass spectrum (insert (b)) and comparison with a synthetic standard. This compound was also present in E. tereticornis leaf volatiles.
