title: Microscopical anatomy of larva of Cheladonta costulata (Acarina: Trombiculidae). I. Glands.
abstract: The larva of Ch. costulata possesses seven paired glands which can be differentiated according to their position and histological structure. In five of them, the dynamics of their secretory or excretory activity may be studied histologically during the feeding process, when not only the deposition of secretion in the gland cells, but also the size of the whole gland is changed. The morphology of the remaining glands is not affected by feeding.
