Abstract
Um ihre Differenzierungsleistungen zu bestimmen, wurden abdominale Imaginalscheiben erwachsener Larven der SchmeißfliegeCalliphora erythrocephala thermokauterisiert, exstirpiert bzw. in gleichaltrige Wirte implantiert. Die Experimente erlauben Aussagen (a) zur Morphologie des Imaginalabdomens und (b) zum Problemkreis der „regulatorischen Aktivitätzwischen Imaginalscheiben“. The differentiation of abdominal imaginal discs of matureCalliphora erythrocephala larvae has been studied by thermocautery and extirpation of the discs, and by implanting them into larval hosts of the same age. The experiments give information on (a) the morphology of the imaginal abdomen, and (b) the “regulative activitybetween imaginal discs”.
