Abstract: The striped field mice are the main pest rodents in most areas in our countiy.They spread several diseases of which the epidemic hemorrhagic fever, in particular, threatens the public health. Although many scholars have studied their morphology, classification, distribution and habits, the study of chemical indexes of these mice hasn't been reported. Their serum proteins, serum lactate dehydrogenase(LDH), crystalline lens LDH and muscle LDH, serum esterase and myogen have been analysed by means of polyacrylamide gel disc electrophoresis. The results obtained are as follows:1. All the striped field mice caught from Shandong Province; Yixing city, Jiangsu Province; Hefei city. Anhui Province are highly similar in LDH isozymes and myogen. That means that they belong to the same species, but there is a subspecies differentiation among them, because their serum proteins reveal differences.2. The animals from Yixing and Hefei belong to the same Subspecies: A.a.ningpoensis, and those from Shandong Province belong to another A.a. pallidior,The differences of the two subspecies are rather clear in some biochemical characters.No A.a.ningpoensis was found in Shandong Province.
