DNA-puffing patterns in the salivary glands of Trichosia pubescens (Diptera-Sciaridae)


The puffing pattern in polytene chromosomes from salivary glands of fourth-instar larvae of Trichosia pubescens was studied. It was found that the puffing pattern is rather constant during most of larval life but changes continuously in a precise sequential order during the period preceding pupation. During this period, characterized by drastic changes in… (More)
