【摘要】 目的了解和掌握辽宁省蚊虫密度及季节消长规律,为制定蚊虫防制方案提供科学依据。方法辽宁省14个市共设立100个蚊虫监测点,采用诱蚊灯法,分别开展农村和城市蚊虫监测。结果2010-2012年共捕获蚊虫67 034只,平均蚊密度为8.12只/(灯·h),淡色库蚊和刺扰伊蚊为优势蚊种,分别占捕蚊总数的44.4%和32.9%。不同生境蚊密度为牲畜棚>农户>公园>医院>居民区。辽宁省蚊虫密度季节消长明显,活动高峰一般在8-9月,5-6月和10月蚊活动较少。结论初步掌握了辽宁省蚊虫密度、种类、季节消长情况,为蚊虫防治以及蚊媒疾病的预防奠定了基础。建议加强蚊虫高峰季节前的控制,加强对蚊虫及其传播疾病的长期监测、预警、控制对策和措施的研究。更多还原

【Abstract】 Objective To investigate the seasonal fluctuation in mosquito density in Liaoning province, China and to provide a scientific basis for developing mosquito control strategies.Methods Light traps were set at 100 monitoring points in 14 cities in Liaoning province to monitor mosquito densities in rural and urban areas.Results From 2010 to 2012, a total of 67 034mosquitoes were captured, with a mean mosquito density of 8.12 mosquitoes/(lamp·h).Culex pipiens pallensandAedes vexans were dominant species, accounting for 44.4% and 32.9% of all mosquitoes. The mosquito density was the highest in barns,followed by in peasant households, parks, hospitals and in residential areas. The mosquito density showed a marked seasonal fluctuation in Liaoning province, with peak mosquito activity in August and September and less mosquito activity in May, June,and October.Conclusion The basic information on mosquito species, their density and seasonal fluctuation has been acquired,laying the foundation for mosquito control and prevention of mosquito borne diseases.更多还原
