Octopamine in the CNS. It is reasonable to suppose that this handful of varied systems where OA has effector functions is only the tip of the iceberg and that more will be discovered. All of these known systems are located peripherally since the demonstration of a specific transmitter role for any compound within the CNS is very challenging. However, there is every reason to believe that OA has important transmitter or modulator functions in the CNS of arthropods. It is synthesized and stored there in plausible amounts (8,9f13) and OA-sensitive adenylate cyclase activity has been found within the CNS of several arthropods. In addition to the examples cited in the recent review by Bodnaryk (26), this activity has been demonstrated in the tobacco hornworm (27f28), Drosophila melanogaster (29)t the tick, Amblyomma hebraeum (27) and the crayfish (30,31) Neurones specifically sensitive to OA have been... 

The previously reported 2,6-dichlorophenol, which is a sex pheromone of several species of tick (1), is also produced by the African tick Amblyomma hebraeum (1662, 1663). This pheromone has been used to control the African bont tick on...

Heartwater is a noncontagious disease caused by Rickettsia ruminantium and the organism is transmitted by ticks of the genus Amblyomma. In east and central Africa A. variegatum is the principal vector, while in South Africa it is A. hebraeum. The disease occurs in subclinical form in at least two species of antelope which probably serve as reservoirs of the organism. A larval tick once infected will retain...
