 note = {Mandibles of workers of Coptotermes formosanus Shiraki were subjected to normal- and micro- PIXE analyses to obtain their elemental profiles.  Among 14 elements, Mn and Fe were evidenced to accumulate in mandibles by normal-PIXE analysis.  By micro-PIXE analysis, Mn was found to preferentially distribute in the cutting edges (teeth) where the pigmentation is also strongest. This may suggest that Mn deposition contributes to the hardening of the exoskeleton, and that the deposition is closely related to pigmentation pattern.},
