The structure of a pregenital abdominal ganglion of the desert locust Schistocerca gregaria (Forskäl)

Abstract

The structure of the seventh abdominal ganglion of the desert locust Schistocerca gregaria is described. Seven transverse commissures are shown to unite the opposing sides of the ganglion and six longitudinal tracts pass through each half of the structure to continue into their respective ventral connective. Seven discrete groups of cell bodies are located within the ganglion.Seventy-six neurone tracts are described and illustrated.
