| 内容記述 | Worker mandibles of two economically important subterranean pest termites, Coptotermes formosanus Shiraki and Reticulitermes speratus (Kolbe), were investigated for their chemical properties and arrangement with special reference to the pigmentation and the particle-removing capacity. Both species deposited Mn in cutting edges of mandibles, and the deposition seemed to be closely related to the pigmentation and the hardening of the mandibles.The maximum openings of mandibles and maxillaes of C.formosanus workers were 0.45mm and 0.88mm, respectively, and the minimum gap between mandibles and maxillaes was 0.07mm.This theoretically results in that C.formosanus workers can remove particles with less than 1.9mm diameters if the particle is spherical in shape, coinciding well with the laboratory test results that 1.7-2.4mm sized particles were effective to prevent the invasion of workers of C.formosanus. In addition, workers of C.formosanus showed the maximum head width of approximately 1.2mm, indicating the particles with less than 2.9mm diameters are small enough to prevent the invasion of workers of C.formosanus. This also has no contradiction with the laboratory test results. These results strongly suggest that basic researches on termite mandibles can be the breakthrough to develop not only new termite control measures but also new biomimetic composite materials. | |||||
