Caste differences in haemolymph proteins in two species of termites

  • M. Wyss-Huber
Article

Summary

Haemolymph proteins and esterases ofMacrotermes subhyalinus and haemolymph proteins ofZootermopsis angusticollis have been analyzed electrophoretically. The patterns were caste specific inM. subhyalinus, but uniform for all castes and sexes inZ. angusticollis. InM. subhyalinus the activities of esterases, especially that of carboxylesterases, and the haemolymph binding capacity for juvenile hormone differend between castes. The results are discussed in relation to the present knowledge about caste determination in lower and higher termites.

Kastenunterschiede in den Haemolymph-Proteinen bei zwei Termiten-Arten

Zusammenfassung

BeiMacrotermes sabhyalinus wurden Haemolymph-Proteine und-Esterasen, beiZootermopsis angusticolhe Haemolymph-Proteine diskelektrophoretisch untersucht. Die Bandenmuster waren beiM. subhyalinus kastenspezifisch, beiZ. angusticollis dagegen einheitlich bei allen Kasten beider Geschlechter. BeiM. subhyalinus wurden zudem Unterschiede in der Aktivität von Esterasen, speziell Carboxylesterasen, sowie in der Bindungskapazität der Haemolymphe für Juvenilhormon festgestellt. Diese Resultate werden in Beziehung gesetzt zu den aktuellen Vorstellungen über Kastendetermination bei niederen und höheren Terrniten.
