[The sensory neuropile of the nerve chain of Eurygaster integriceps P].
Structure of the sensory neuropil of the abdominal nervous chain has been studied in the Eurygaster integriceps P. by means of methylene blue and paraldehyde fuchsin with phloxin staining. The sensory neuropil consists of three parts: 1) main sensory neuropil, including terminal, T-shaped, antero- and posterconnective fibers; 2) lateral sensory neuropils of the extremities, that in the insect studied, as in the dragon-fly larva, have the form of the overturned eight; 3) system of thick T-shaped fibers getting into the first thoracic ganglion and running along the second nerves, as well as along the thoracic neuromeres of the synganglion, giving collateralies into the nuclei of the extremities and into the main neuropil and coming into both the abdominal and cranial parts. In the neuropil of the extremities certain fibers are revealed; they form collateralies in the nucleus itself and terminate in the main neuropil. Of all the insects investigated it is the Eurygaster integriceps P. that possesses the most developed sensitive nuclei in the extremities and the least developed nuclei in the wings.
