 Title    Alterations in Ecdysone Content during the Post-Embryonic Development of Chironomus thummi: Correlations with Chromosomal Puffing  
 Abstract    The ecdysone titer o f larvae and pupae o f Chironomus thum m i was determined by radioimmune assay (R IA) and revealed a concentration of about 150 ng/g fresh weigth in late third instar larvae and a peak of more than 450 ng/g fresh weight just preceding pupation. The ecdysone titer curve shows a high degree o f correlation with previously observed puffing activity at the ecdysone sensitive chromosomal site I l l d l . Further, //-ecdysone is the only endogenous ecdysone detected by high pressure liquid chromatography during larval-pupal development. It was also observed that developmentally arrested Chironomus contain less ecdysone than " normal" larvae.
