Term

embryonic/larval corpus allatum

ID (Ontology)

FBbt:00001725 (Fly Anatomy)

Definition

Neurohemal organ found medially in the anterodorsal part of the larval ring gland, surrounded by cells of the prothoracic gland (Dai and Gilbert, 1991; de Velasco et al., 2004). It is composed of smaller cells than the prothoracic gland (Dai and Gilbert, 1991). It produces juvenile hormone (Dai and Gilbert, 1991; Hartenstein, 1993).[ FlyBase:FBrf0053727 FlyBase:FBrf0064803 FlyBase:FBrf0089570 FlyBase:FBrf0179777 ]
