title: The larval integument of Calliphora erythrocephala Meigen (Diptera : Calliphoridae) during metamorphosis. Changes in macromolecular content and in incorporation rate of labelled precursors.
abstract: The amount of proteins, RNA and DNA in the larval integument of Calliphora erythrocephala, decreased markedly when metamorphosis began. The total incorporation per epidermis of labelled precursors also decreased at this time, but far less in RNA than in DNA and proteins. Thus, incorporation, when expressed in terms of specific activity, decreased in proteins, remained stable in DNA and increased in RNA. The significance of these results is discussed.
