Abstract：Objective To learn the vector invasion status at the venues and reception hotels involved in the Chengdu World Science Fiction Convention,take timely vector control measures to ensure the vector-borne safety at the convention,so as to summarize the experience and provide effective reference for the future major events.Methods Prior to the Chengdu World Science Fiction Convention,In September and October 2023,three rounds of vector density monitoring and vector control effectiveness assessment were conducted at one main venue and five reception hotels involved.The analysis focused on the infestation and control effects of cockroaches,flies,mice and mosquitoes at each location.Results Three rounds of density monitoring showed that the overall cockroach trapping rate,cockroach trace positivity rate,and adult flies invasion rate in six locations showed a significant declining trend(cockroach trapping rate:1.74％,0.97％,0.24％,cockroach trace positivity rate:5.15％,2.63％,0.39％,adult flies invasion rate:3.76％,1.47％,0.00％,P＜0.05).No mice were captured at all locations,and no traces of mice were found indoors.The overall mosquito trap lamp mosquito density,landing index,and path index in six locations showed declining trend.The evaluation of vector control effectiveness showed that the density control of mosquitoes in all locations had reached level A,flies and cockroaches had reached level B,mice in hotel A and hotel E had only reached level C,while the density control level for mice in other locations had reached level B.Conclusion As time goes on,the vector prevention and control effects of the venue and reception hotels of the Chengdu World Science Fiction Convention continue to improve.Conducting monitoring of vector density and evaluation of control effectiveness can provide scientific basis for vector control and objectively reflect the effectiveness of vector control.
