[The alveolar salivary glands of hungry larvae of the chigger Hirsutiella zachvatkini].

Heteromorphic parasitic larvae of Hirsutiella zachvatkini have four pairs of simple alveolar salivary glands possessing characteristic peculiarities of electron microscopic organisation. Each of paired granulosecreting salivary glands has its own dynamics of secretory activity, which is stimulated by a specific functional role connected with feeding on the host.
