[Studies on identification of Gryllotalpa by near-infrared diffuse reflectance spectrometry].

Objective: To identify and analyse the different species, same species in different regions and confusion species.
Method: Near-infrared diffuse reflectance spectrometry was used.
Result: Clustering analysis showed that clustering relations were far among different Gryllotalpa species and close among the same species from different regions, and there were close relations among the same species from near regions and between Teleogryllus emmus and G. orientalis.
Conclusion: Near-infrared diffuse reflectance spectrometry method can be used in classification and identification of Gryllotalpa.
