Abstract:In this study, the dominant population was determined through the survey of farm rodents. According to the living conditions, behaviors, population characteristics and other biological characteristics of different dominant populations, we have formulated scientific prevention and control principles. Before the control, the rat density in the pigsty was 100%, and the feed library rat density was 70%. Five continuous followup evaluations in January, February, March, April, and May after the comprehensive prevention and control, the rat density decreased to low density respectively. In the process of rodent control on farms, from the investigation of rodent species to comprehensive prevention and control, the prevention and control idea of continuous tracking and evaluation of rodent control effect is ideal.
