It plays a prominent role in modulating multiple physiological and behavioural processes in insects. Octopamine exerts its effects by binding to specific proteins that belong to the superfamily of GPCR's. We picked up three partial sequences of putative octopamine receptors in S. gregaria (SgOctαR1, SgOctαR2 and SgOctβR) using degenerated primers and investigated their transcript levels in males and females of both phases and during the transition between long-term solitarious and gregarious locusts. The transcript levels of the SgOctαR's are the highest in the CNS, whereas those of SgOctβR are the highest in the flight muscles, followed by the CNS. Both SgOctαR1 and SgOctβR show higher transcript levels in long-term gregarious locusts compared to solitarious ones. The rise of SgOctβR transcript levels already appears during the first four hours of gregarisation, in which also the behavioural changes take place.
