Summary

Mature larvae, one day and three days old pupae, one day and ten days old adultDrosophila melanogaster males were assayedin vitro for the enzyme, xanthinedehydrogenase. Very high enzyme activity was found in wildtype and bothw andbw throughout the period investigated. Also 6 days oldwhite flies proved to be able to form isoxanthopterin from 2-amino-4-oxypteridine in anin vivo assay. The results are discussed with regard to the absence of isoxanthopterin and uric acid inwhite andbrown imagines.
