Composition and role of volatile substances in atmosphere surrounding two gregarious locusts,Locusta migratoria andSchistocerca gregaria (original) (raw)

Abstract

Volatile substances in the atmosphere surrounding gregarious locusts_Schistocerca gregaria_ and_Locusta migratoria_ were captured and investigated by combined gas chromatography-mass spectrometry. Three aromatic derivates have been identified: phenol, guaiacol, and veratrole. Their relative percentages differ for different ages and species. Behavioral tests show that essentially phenol, guaiacol, and the mixture of the three products tend to increase the aggregation behavior in both species and thus act as “cohesion pheromones.”
