Neurosecretory Cells in the Abdominal Ganglia of Larvae of Lucilia caesar (Diptera)

ALASTAIR FRASER 1

1 Department of Zoology, University of Glasgow

Ten neurosecretory cells can be found in each of the first 5 abdominal ganglia of the larva of L. caesar L. These are arranged as two lateral pairs and a single ventral cell in each half of a ganglion. Half the lateral cells go through a cycle of secretory activity before pupation in developing larvae. In diapause larvae while half the lateral cells are in a resting phase the remainder are in various stages of secretory activity. The destination of the product is not known. Chemically this product is, unlike that of brain neurosecretory cells, PAS-positive. It may contain a glyco- or phospholipid or lipoprotein component.
