Abstract: Objective: To find out optimal habitats for wild rats, especially for A.agrarius, so as to provide scientific data for rodent control. Methods: In the surveyed area, slope weirs (stone, earth) and graveyards were classified as one habitat, wheat fields and spring fields as the other. The night trapping method was used to determine the rat species and density in the two different habitats. Results: The rat density was 4.25% in slope weirs and graveyards, 0.83% in wheat and spring fields. The rat density was 4.12 times higher in the former than that in the latter. The slope weirs and graveyards covered 1/10 of the total area. Conclusion: Slope weirs and graveyards are optimal habitats for wild rats in hilly area. Deratization in optimal habitats can save a great deal of rodenticide and labour and can achieve better effect. It is of great significance and academic value for effective rodent control and Hemorrhagic Fever with Renal Syndrem control to find out optimal habitats for wild rats in hilly areas.
