漳泽湖国家城市湿地公园摇蚊绿色防治技术

Preliminary exploration of the green control technology for chironomidae at Zhangze lake national urban wetland park

目的为避免摇蚊大量发生导致的干扰游览环境、水体污染、公共卫生安全事件等情况出现,并为重大活动提供环境安全保障,针对摇蚊开展绿色防控,控制种群密度.方法通过监测调查、环境友好型药剂复配增效应用、物理防治、环境治理4项措施构成绿色防治体系展开综合防治.结果掌握了湿地公园摇蚊发生规律,取得了摇蚊种群相对密度下降率高达83.13,一年中摇蚊种群数量随防治工作的进行呈阶梯式平缓下降的良好效果,且防治区域摇蚊种群密度显著低于对照区域.结论证明了在保护生态环境的前提下,可以通过摇蚊绿色防治技术将摇蚊种群数量有效控制在环境容忍的水平之下.

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.
