- Abstract
The aim of this study was to identify the nest materials, some physical characteristics and the essential composition of the nest of Vespa crabro germana Christ, 1791. Nest surfaces were observed with a stereomicroscope and a scanning electron microscope. In the inner surface of the V. c. germana nest, the medium thicknesses of the fibers in the envelope and comb varied between 5.30 and 11.90 µm with an average of 9.07 µm. In the outer surface of the nest, the medium thicknesses of the fibers in the envelope and comb were between 4.46 and 11.40 µm with an average of 7.68 µm. The nitrogen and protein concentration of the nest was 0.22 and 1.40%, respectively. The percentages of the fibers, saliva, oil and the water absorption capacity were calculated as 70-75, 25-30, 16-20 and 120-150, respectively. The amount of the elements nickel and copper in the nest was found to be 0.6 and 1.2 ppm, respectively. The major components of the nest were plant fibers, saliva and oil. Consequently, we have found that the ratios and the amounts of physical characteristics, the element composition and the fibers in the envelope and comb of the nest changed with environmental conditions.
