abstract
The aim of this study was to determine the structural features of the nest materials of Crematogaster rogenhoferi with some parameters like height above the ground in which the nest carton was build or constructed, weight of the nest material, length, width, diameter of cell, height of trees, element compositions, absorbency capacity and temperature were studied in the month of September 10, 2014. The nest materials are thick and condensed, which constitutes plant fibers and soil particles. Presences of fungal hyphae were seen under SEM. The average height above the ground was 242.7±54.42cm, weight 494.4±72.58cm, length 17.26±0.15cm, width 7.92±0.37cm, diameter of the cell chamber 2.06±0.31cm and height of trees was 9.04±4.79 cm respectively. Oxygen and Carbon were high concentrations while K, Hg, Cu, Al and Br were in low concentrations. The total percentage of water absorbency capacity was 22.92±9.11and the average temperature was about 22.35±0.86 °C.
