Primary sensory projections of the labial palp pit organ of pieris rapae l. lepidoptera pieridae


International Journal of Insect Morphology and Embryology 15(5-6): 439-448
Primary sensory projections of the labial palp pit organ of pieris rapae l. lepidoptera pieridae
The primary sensory projections from the sensilla of the terminal segment of the labial palp of Pieris rapae were examined using cobalt staining and experimental degeneration. Most of the fibers can be assumed to be the axons of the labial palp-pit organ (LPPO). They project bilaterally to a single glomerulus at the posteroventral margin of the antennal lobe (LPPO glomerulus). A single glomerulus in the same location remained unstained when cobalt was applied to the antennal nerve. A smaller number of fibers project to the medial part of the subesophageal ganglion. Both palpal projections are bilateral in contrast to the strictly unilateral antennal projections. Experimental degeneration of axon terminals of 0.5 .mu.m diameter was observed within the LPPO glomerulus. The terminals contain several conventional chemical synapses with 2-4 postsynaptic profiles linked to each of them. The results suggest that the output from the LPPO is processed separately in the antennal lobe and that the antennal lobe integrates information from several segments.
