Abstract: There are 7 main species of agricultural rodents in Hunan Province: R. norvegicus, A. agrarius, R.rattoides, R.flavipectus, M.fortis, Mus musculus and R.confucianus.The rodent pest area in Hunan Province can be divided into 5 types according to the dominant species:( 1 ) M. fortis pestarea, ( 2 ) R. norvegicus and A. agrarius pest area, ( 3 ) R. flavipecius and R. ratioides past area, ( 4 ) M. musculus and R. rattoides pest area, ( 5 ) R. confucianus pest area.The percentage composition of rodent species varied with seasons and years. The heavy losses were caused by R. norvegicus. They characterized by the habits of den and food selection, the composition of community and competition between species of rodents in different areas. It is helpful to investigate these characteristics to select baits and use the bait correctly."The second hit" can solve the problem of the remainders of mice.
