1. Various biogenic amines, their precursors and metabolites in gregarious and solitary forms of the flour beetle Tribolium freemani Hinton larvae were measured using high-performance liquid chromatography coupled with electrochemical detection. 2. Octopamine was much more abundant than dopamine, serotonin, epinephrine, norepinephrine and related substances, suggesting that octopamine may play much more important roles in growth and behaviour of T. freemani than other biogenic amines and related substances. 3. Octopamine levels were higher in gregarious forms than solitary forms of T. freemani larvae, and the relation between octopamine content, hormone cycles and motility is discussed.
