Abstract：Objective In order to avoid disturbance to the tourist environment,water pollution,public health and safety incidents caused by a large number of chironomids,and to provide environmental security for major activities,the project team carried out the green prevention and control of chironomids to control its population density.Methods The green control system was formed through monitoring and investigation,application of environmental friendly compound,physical control and environmental management.Results The project team has mastered the occurrence pattern of chironomid in the wetland park and has achieved good results,the relative density decline rate of the chironomid mosquito population has reached 83.13.Throughout the control measuresand,a gradual staged decline in the population of chironomidae in the year,and the population density of chironomid mosquitoes in the prevention and control area is significantly lower than that in the control area.Conclusion Through the green control technology,chironomidae populations can be effectively controlled below the level of environmental tolerance while protecting the ecological environment.
