We have used an enzyme-linked immunoassay (ELISA) for determination of the AKH content in CNS (brain + corpora cardiaca + corpora allata) and haemolymph of adult macropterous and brachypterous females of the bug Pyrrhocoris apterus. The tests revealed that the AKH content fluctuates between 1 and almost 4 pmol/CNS during the first 14 days of adult life and(More)
In the present paper we studied the effects of five biogenic amines - norepinephrine, dopamine, octopamine, serotonin and histamine - on the locomotory activity and mobilization of lipids in the adult females of the firebug, Pyrrhocoris apterus (L.). We tested the hypothesis (1) whether the stimulation of walking activity in the bugs injected with the(More)
A new member of the AKH/RPCH family was isolated from the corpora cardiaca of the firebug Pyrrhocoris apterus. It is the second adipokinetic peptide identified in this species. The peptide was characterized and its structure was deduced from the multiple MS(N) electrospray mass spectra as that of an octapeptide with the sequence(More)
