| Summary: | This work was aimed at identifying the pheromone component(s) of the great Capricorn longhorn beetle (Cerambyx cerdo). Volatile samples from beetles were obtained by means of collection of headspace volatiles from the animals, and by direct solvent extraction of body parts, and analysed by gas chromatography-mass spectrometry (GC-MS) and gas chromatography- Electroanntennography (GC-EAG). The chemical analyses were accompanied by behavioural studies. No potential pheromone candidate(s) was identified, neither in the GC-MS analyses nor the GC-EAG analyses. However, the behavioural studies in a two-way choice olfactometer using live beetles as odour sources suggest that the males emit pheromones attracting the females. |
