LOCUS OF ACTION OF DDT IN FLIES 151 THE IMPORTANCE OF THE CENTRAL NERVOUS SYSTEM The central nervous system of Drosophila is concentrated in the anterior part of the body. In the larva the central nervous system is located in the third thoracic and the first abdominal segments; it consists of the two brain hemispheres, to which is attached a large ganglionic mass (Figs. 1 and 3). This large ganglion is a compound structure, for it includes the sub-oesopliageal ganglion, the three thoracic ganglia, and the eight abdominal gan

This large ganglion is a compound structure, for it includes the sub-oesopliageal ganglion, the three thoracic ganglia, and the eight abdominal ganglia. In the adult insect the three thoracic ganglia are separated, but all eight abdominal ganglia unite into one ganglionic mass which extends into the first segment of the abdomen (Fig. 2)..
