title: Octopamine distribution in the tsetse fly Glossina morsitans.
abstract: Tissues of Glossina morsitans were assayed for octopamine using an enzymatic technique. Octopamine was detected at the highest concentration in the brain (7.06-7.99 ng mg-1 tissue protein) and thoracic ganglion (10.9-13.89 ng mg-1 tissue protein). Octopamine was present in haemolymph at a concentration of 1.0-1.27 X 10(-7) M. This was not found to vary when insects were flown or mechanically stressed. Nervous tissue, flight muscle and haemolymph showed a significant ability to metabolize octopamine. The greatest enzyme activity was present in the haemolymph.
