✦ Synopsis

The iodine metabolism of vertebrates, especially of mammals, has been extensively studied. In contrast, iodine metabolism in insects has received relatively little attention. Wheeler ( '47, '50) and Slipka ( '52) noted cuticular concentration and Wheeler ('50) separated several iodinated intermediates by paper chromatography. She suggested that these $might be iodide, 3-monoiodotyrosine, 3, 5-diiodotyrosine, and elemental iodine. This study concerns iodine metabolism in insects so that it may be compared with that of mammals.

METHODS

Handling of insects.

The methods of treatment of the following insects are listed in table 1: a dragonfly, Aeschrza sp. ; the American cockroach, PeripZarzeta ainericana (L.) ; the German cockroach, BZatteZZu germmica (L.) ; a cicada, Tibicerz sp.; the squash bug, Annsa tristis (DeGeer); the larger cabinet beetle, Trogodermn versicolor (Creutz.) ; the locust borer, Megacyllene robinae (Forst.) ; the greater wax moth, Galleria melZorzella (L.) ; the gay harlequin caterpillar, Euchaetias egZe Drury ; a mud dauber, Sceliphr-orz cementurium (Drury) ; the yellow fever mosquito, Aedes aegypti (L.) ; and the house fly, Musca domestica L.
