蟋蟀音齿的研究(直翅目：蟋蟀总科)

This paper studied the teeth of crickets by using scanning electron microscope.10 species belonging to 5 genera under 3 family of Grylloidea were studied.The results revealed that individuals of the same species had almost identical teeth but individuals of different species often had dramatic differences in their teeth.Hence teeth could be used as important identification characters of crickets.Morever,the possibility of using teeth to classify generic taxa was discussed.
