第十三届全国运动会水上竞赛项目病媒生物调查分析

Survey on vectors in the Water Sport Event in the 13^(th) National Games in China

目的调查第十三届全国运动会(全运会)水上竞赛项目病媒生物密度及其分布,为科学制定防制措施提供依据。方法根据《天津市病媒生物监测方案》,于2017年6-7月对第十三届全运会水上竞赛项目周边的蚊、蝇、鼠和蜚蠊孳生生境及其密度进行调查。结果全运会水上竞赛项目主要受蚊虫和鼠类侵害。河道沿岸景观带以及拆迁区灌木丛成蚊侵害严重,蚊密度分别为38.50和43.96只/(灯·h),芦苇荡和小型积水为蚊幼虫的孳生场所,勺舀指数分别为12.00和9.17条/勺,围墙及拆迁区域鼠类侵害严重,鼠密度分别为2.15%和1.54%。结论前期完善的病媒生物调查为制定科学的防控措施提供了技术支撑,是全运会水上竞赛项目病媒生物防制成功的关键。

Objective To know the habitats and population distribution of the main vectors for the Water Sport Event in the 13^th China National Games, to provide basis of making scientific control measures. Methods According to The protocol of vector surveillance in Tianjin, developing the survey of the habitats and population distribution of the main vectors in the Water Sport Event from June to July 2017. Results The main vectors in the Water Sport Event in the 13^th National Games were mosquitoes and rodents. There was potential risk of mosquito breeding in river bank, landscape belt and demolition zones. The mosquito densities were 38.50 and 43.96 mosquitoes per light trap per hour. The reed marshes and small-scale pond provided the breeding places for mosquito larvae, the indexes were 12.00 and 9.17 larvae per dip. Rodents prevailed at 2.15% and 1.54% capture rate in the demolition zones. Conclusion The careful surveillance of the main vectors provided basis for making effective integrated control measures, and it is the key factor of successful vector control for the Water Sport Event in the 13^th National Games in China.
