Gas Chromatography-Mass Spectrometry in Insect Pheromone Identification: Three Extreme Case Histories
Use of modern gas chromatography-mass spectrometry (GC-MS) for the identification of insect pheromones, using a minimum of insect material, is described for three extreme cases: (i) a mosquito oviposition pheromone: a GC-MS peak but no evidence of activity; (ii) the Siiona lineatus aggregation pheromone: no GC-MS peaks in active region; (iii) aphid sex pheromones: GC-MS peaks associated with activity — the ideal situation.
