Morphologie und Histologie der Speicheldrüsen der männlichen Skorpionsfliege Panorpa vulgaris Imhoff & Labram (Insecta: Mecoptera, Panorhidae).

Abstract

The morphology and histology of the salivary glands of the males of Panorpa vulgaris (Mecoptera, Panorpidae) are described. Each of the two male salivary glands consists of 2-4 appendix tubes and produces a secrete intended as a 'courtship meal'. The development and the filling of the glands, as wellas the structure of the gland epithel of adult scorpion flies depend on the food intake during the larval phase, since the glands of adult Panorpa developed equally well under both feeding regimes. The glands produce a secrete which reacts positively to histochemical protein staining.
