Three groups of adult females of P. apterus (reproductive, diapausing and macropterous) were analysed for their adipokinetic response, sensitivity of the fat body to Pya-AKH and locomotor activity during a 24 hour cycle. The highest both adipokinetic response and the activity of walking was observed in macropterous females. Diel changes of adipokinetic response were recorded in all groups, with maximal response occurring during the day at 6-7 h after the onset of light. Diel changes in locomotor activity were found only in reproductive and macropterous females, and showed a diurnal rhythm with only one peak of activity during a 24 hour cycle. The rhythmic pattern of walking activity was positively correlated with diel changes of adipokinetic response in macropterous females only.
