Objective To understand the background situation of the rodents at Guangzhou ports along the Zhujiang River, and to provide scientific evidence for rodents prevention and control, improving the mechanism of prevention and control of communicable diseases. Methods Night trap was used to investigate rodent population, density, seasonal growth, reproduction, and carrying parasites. Results A total of 1 984 rodents were captured and identified as 2 orders 2 families 3 genera 8 species. Rattus rattus alexandrinus Geiffrong was discovered for the first time at Guangzhou ports. The dominant species were Suncus murinus Linnaeus and R.norvegicus Berkenhout. The annual average density was 2.26%. There were two peaks from Septemker to December and June. Conclusion The investigation provides scientific basis for the prevention and control of rodents and related communicable diseases at Guangzhou ports along the Zhujiang river.
