Abstract


The aim of this study is to determine the nest materials and some physical features and elemental composition of the nests of Polistes nimpha (Christ) collected in different ecological conditions. The nests were collected in Aksaray, Adana, Konya, Niğde, Malatya, Uşak provinces of Turkey. The nest surface was observed, the thickness of plant fibers was measured and an Energy Dispersive X-Ray Analysis was carried out by Scanning Electron Microscope. The percentage of the nest materials and the water absorption capacity were calculated.

The results indicate that the nest architectures of the samples and the nest surface are similar. The colors of the nests are beige and grey along dark grey lines. There are differences in respect to the fiber thickness, the elemental composition and their amount, the percentage of fiber and saliva, and the water absorbency. Amounts of plant materials and oral secretions, the nitrogen concentrations in the nest walls, the nest wall’s absorption capacity of P. nimpha were calculated between 37-61% and 39-63%, 25.82% and 30.22%, 217% and 764%, respectively. These differences may be related to choosing of fiber, the environment of the colonies and the production of paper.
