Summary
In honeybee workers derived from Italian and African stock, high concentrations of 2-heptanone in the mandibular glands were found to be positively correlated with several manifestations of aggressive behaviour at the hive entrance. Amounts of iso-amyl acetate from the sting apparatus were also assayed, but correlations with behavioural characters were not significant.
