N2 - The adipokinetic hormone (AKH-I and AKH-II) content of the corpora cardiaca from adult males of crowded (gregarious) and isolated (solitary) Locusta migratoria migratorioides (Reiche and Fairmaire) was quantified by reverse-phase high-performance liquid chromatography. Significantly less total hormone was found in the corpora cardiaca of crowded locusts than in those glands of isolated locusts at the age of 12-19 days after fledging. The ratio of AKH-I/AKH-II was higher in crowded than in isolated locusts at this age. From the age of 12-19 days to that of 25-30 days, AKH content increased significantly in the corpora cardiaca of crowded locusts, but no such increase was found in the glands of isolated locusts, and at 25-30 days there were no significant differences in the AKH content of the glands from crowded and isolated locusts.
