Let mosquitoes, flies, cockroaches, and rodents have nowhere to escape - Hefei Xinqiao Airport Customs delivers impressive results in vector control work for 2025
At Hefei Xinqiao International Airport, an invisible 'war' is ongoing year-round - customs officers compete with vector organisms such as mosquitoes, flies, cockroaches, and rodents on the front line of the country, racing against potential epidemic risks. In the just passed year of 2025, the customs of Hefei Xinqiao Airport, under the jurisdiction of Hefei Customs, submitted an impressive "report card": the monitoring and capture of adult mosquitoes in the port area decreased by 90.6% year-on-year (the same below), and the mosquito egg density index decreased by 50.5%; The density of rodents has decreased by 26.3%, the density of parasites carried on their bodies has decreased by 55.3%, and the overall density of cockroaches and flies has decreased by 12.1% and 5.52% respectively. The ecological environment at the port continues to improve, and the national biosafety barrier has been further strengthened. Behind the numbers is a scientifically precise and sustained defense battle for national biosafety.
Scientific monitoring, precise drawing of risk maps
Port vector monitoring is a fundamental project for building a national biosafety prevention and control system. The customs of Hefei Xinqiao Airport will shift its monitoring work from "passive response" to "active warning", and establish a monitoring network covering the entire port and throughout the entire time period. By analyzing and comparing the monitoring data of vector organisms over the years, a "vector organism risk heatmap" has been drawn to accurately determine the peak period of vector organism density and the core risk area, providing scientific guidance for targeted prevention and control measures.
In 2025, the customs of Hefei Xinqiao Airport will introduce various high-tech monitoring equipment such as infrared real-time intelligent mouse traps and new solid-state carbon dioxide mosquito traps, and accurately deploy a "sky and earth network" in high-risk locations such as catering enterprises' catering rooms, cargo warehouses, passenger passages, and garbage disposal areas to achieve dynamic monitoring and intelligent warning of vector organisms, further improving monitoring and governance efficiency.
Vector monitoring is not just about counting, but more about species identification and pathogen screening, "said Duan Jinlei, head of the Customs Health Supervision Department at Hefei Xinqiao Airport
Environmental governance cuts off the transmission chain at the source
The key to reducing the density of vector organisms is to eliminate their breeding environment. The customs of Hefei Xinqiao Airport focuses on "addressing the root cause and clearing the source", and regards deepening environmental governance as a key link in doing a good job in monitoring and preventing vector borne diseases.
Find loopholes under the microscope. The customs officers conducted environmental inspections in the port area and did not miss any potential risk points. They inspect various types of water accumulation containers, supervise and guide port operators to clean up waste and debris, ensure smooth drainage systems, and ensure daily cleaning and closed transportation of solid and liquid waste in the port area. At the same time, stricter hygiene standards will be implemented for key areas such as catering and food storage to reduce the food sources, water sources, and habitats of vector organisms from the source. In 2025, the density index of Aedes eggs in the port area of Hefei Xinqiao International Airport will decrease by more than 50% year-on-year, which is a direct reflection of the continuous supervision and clearance of small stagnant water by customs and the elimination of Aedes mosquito breeding grounds.
No blind spots "type of intrusion prevention. Hefei Xinqiao Airport Customs instructed the stationed units to implement protective facilities transformation and preventive disinfection and sterilization for green belts, wasteland, living quarters and other habitats in the port area, effectively blocking the transmission and diffusion path of vector organisms. At the same time, precise disinfection and sterilization is carried out based on the time, space and population distribution of vector organisms to achieve the unity of scientific prevention and control and ecological security.
"The airport has a wide range of vegetation and waters, and the density of mosquitoes and flies has remained high over the years, making disinfection and sterilization difficult. Before the summer of 2025, the customs will guide us to install protective equipment such as wind curtains and screens in the covered bridges, warehouses, basements and other areas, and suggest that we use low toxic and highly effective insecticides for space spray disinfection and sterilization, effectively protecting the ecological environment of the port." Zhan Xiyan, director of Hefei Xinqiao International Airport Emergency Center, introduced.
Collaborative governance and joint efforts to build a three-dimensional barrier
The solid and stable national biosafety barrier cannot be achieved without close collaboration across departments and fields. The customs of Hefei Xinqiao Airport will promote the integration of core public health capacity construction into the local public health system, and establish a "big prevention and control" pattern of joint prevention and control.
"We took the initiative to open up the 'last hundred meters' of the port vector monitoring system." Fei Mingshan, Deputy Director of the Customs of Hefei Xinqiao Airport, said, "We have established a regular information notification and joint action mechanism with the local disease control, health, airport management, municipal sanitation and other departments. Hefei Airport has now achieved the sharing of vector monitoring data and epidemic information at the customs. The joint research and judgment of epidemic prevention and control risks in the port area, as well as the environmental disinfection and sterilization management work have also been carried out jointly."
In addition, the customs of Hefei Xinqiao Airport actively tap into its potential internally, strengthen the professional training of port health supervisors and quarantine physicians, enhance their ability to identify, monitor, and respond to vector borne diseases, and expand outward through posting propaganda posters, distributing propaganda manuals, and conducting on-site answers. They actively promote vector borne disease hazards and prevention knowledge to port employees, passengers, and other groups, continuously enhance public awareness of biosafety, and strive to build a pattern of "everyone participates, group prevention and treatment" for national biosafety.
From species identification of a mosquito to cleaning of a stagnant water container; From the insistence on the deployment of monitoring equipment in the morning and evening to the consultation at the joint prevention and control coordination meeting... The customs officers of Hefei Xinqiao Airport Customs used rigorous scientific spirit and meticulous work style, in exchange for the continuous improvement of the port ecological environment and the continuous reduction of public health risks, effectively preventing the spread risk of yellow fever, dengue fever, pestis and other infectious diseases.
At present, Hefei Xinqiao Airport is undergoing the second phase of renovation and expansion project. The newly built T2 terminal is expected to meet the development needs of an annual passenger throughput of 40 million and a cargo and mail throughput of 350000 tons. The customs of Hefei Xinqiao Airport will take this opportunity to firmly fulfill their responsibilities and missions of guarding the country's borders and promoting development. With more scientific monitoring, more accurate prevention and control, and more efficient cooperation, they will continuously enhance the core capabilities of public health at the port and build a solid barrier for the biosecurity of Hefei Airport Port.
