Abstract

Objective To investigate rodent population distribution and rodent control effectiveness in a working area of Japanese abandoned chemical weapons in eastern Jilin province, China. Methods The trapping method was used to capture rodents from June to August of 2016 in 3 habitats (mixed coniferous-broadleaf forests, marginal areas of cultivated land, and temporary settlements). The chi-square test was used to compare the capture rate of rodents in different habitats. Rodent control was conducted with poison baits in 4 zones of the working area and the control effectiveness was determined in July 2017. Results A total of 398 rodents were captured, involving 10 species from 8 genera. The dominant species were Apodemus agrarius (37.19%) and Tscherskia triton (32.66%), followed by Rattus norvegicus (9.30%) and A. peninsulae(8.54%). After 10 days of deratization, deratization rates in the 4 zones were 71.43%, 84.85%, 81.25%, and 91.30%, respectively, averaging 84.79%.The difference of mousetrap rate between different habitats and month was statistically significant (χ2=119.431, P<0.001; χ2=15.872, P<0.001). Conclusion There were many kinds of rodents in this area, the density of rodents was high, and the effect of poison bait is remarkable.
