摘要
目的了解山东省消除疟疾后蚊虫种群及传疟媒介中华按蚊密度现状,为消除疟疾后输入性疟疾再传播风险评估及输入性疟疾防控策略的制定提供依据。方法于2021年6~10月在山东省所辖16设区市监测点采用全通宵诱蚊灯法监测蚊虫种群;采用人饵帐诱捕法监测中华按蚊密度。结果全通宵诱蚊灯法共捕获蚊虫43684只,其中中华按蚊393只,库蚊40305只,伊蚊1145只,其他蚊种1841只;人饵帐诱捕法共捕获中华按蚊1149只,平均密度为0.874只/(人·h)。8月上旬中华按蚊密度达到峰值,为1.903只/(人·h)。全省以济宁市微山县中华按蚊平均密度最高,为8.442只/(人·h);滨州市滨城区中华按蚊密度次之,为5.039只/(人·h)。结论山东省蚊虫种群分布以库蚊为主,中华按蚊在济宁市微山县和滨州市滨城区7~8月份活动峰度高,应加强中华按蚊活动重点区域的生态学监测。
Objective To understand the current situation of mosquito population and malaria vector mosquitoes density after the elimination of malaria in Shandong Province,and to provide a basis for the risk assessment of imported malaria after the elimination of malaria and the formulation of imported malaria prevention and control strategies.Methods A total of 16 vector monitoring points were set up in the province,and monitoring was carried out during the peak season of mosquito activity from June to October every year.The distribution of mosquito populations was monitored by all-night mosquito trapping method for at least three consecutive nights;the density of Anopheles mosquitoes was monitored by human account method twice a month,from sunset to the next morning,with one capture per hour and 15 minutes per capture.Results A total of 43684 mosquitoes were captured by all-night mosquito trapping method,including 393 Anopheles mosquitoes,40305 Culex mosquitoes,1145 Aedes mosquitoes,and 1841 other mosquito species.A total of 1149 Anopheles mosquitoes were captured by human account method,with an average density of 0.874 mosquitoes/(person hour).The density of Anopheles mosquitoes reached its peak in early August,at 1.903 mosquitoes/(person hour).The average density of Anopheles mosquitoes in Jining City was the highest in the province,at 8.442 mosquitoes/(person hour);followed by the density of Anopheles mosquitoes in Bincheng District,Binzhou City,at 5.039 mosquitoes/(person hour).Conclusion The mosquito population in Shandong Province is mainly composed of Culex mosquitoes,while the density of Anopheles mosquitoes is high in Weishan County,Jining City and Bincheng District,Binzhou City,during the peak season of mosquito activity from July to August every year.Therefore,ecological monitoring of Anopheles mosquitoes in key areas of Shandong Province for malaria vector control should be strengthened.
