The Malpighian tubules of Drosophila melanogaster accumulate a considerable quantity of Tryptophan as well as Kynurenin and Oxykynurenin especially after pupation, because the histolytical processes begin at this time. In the wild-type this Tryptophan is utilized for the formation of Kynurenin, Oxykynurenin and Ommochromes, while in the mutant r, which is uncapable of forming these compounds, it is stored in the Malpighian tubules and the (Tryptophan) contents reaches 20 times the norm. This accumulated Tryptophan is excreted during the larval stage, after hatching and in the following days, while the meconia and excrements of the wild flies contain no Tryptophan.
