Title: Vitellogenin accumulation in the fat body and haemolymph of Locusta migratoria in relation to egg maturation
Abstract: Vitellogenins first appear in the fat body of Locusta migratoria during subphase I of vitellogenesis and increase to a constant level during subphase II. A second increase occurs shortly before the oöcyte attains maximal size. Vitellogenin content of fat body subsequently returns to that of subphase I, appropriate to the size of the subterminal oöcyte. The absolute amount of vitellogenin in the fat body is low compared to that found in the haemolymph. Fat body and haemolymph vitellogenins have immunological properties similar to oöcyte yolk proteins—when challenged with oöcyte protein antiserum. They exhibit similar electrophoretic mobility in polyacrylamide gel electrophoresis and are complex glyco-lipoproteins.
