Figure 3.

Comparison of the piling rates of termite eggs, termite balls and dummy eggs (glass beads). Glass beads (0.2, 0.4 or 0.6 mm in diameter) that were coated (c) or not coated (nc) with egg chemicals were used as dummy eggs. For example, 0.2-c and 0.2-nc indicate 0.2 mm glass beads that were and were not coated with egg chemicals, respectively. Termite balls collected from egg piles were carried at the same rate as were termite eggs (Mann–Whitney U-test, Z=0.72, p=0.382). Different letters indicate significant differences at the 0.05 level, as shown by post hoc Scheffé's tests. Note that 0.4 mm beads are within the range of the short diameter of termite eggs.
