目的掌握广州白云机场候机楼二期建设区域内医学媒介生物(鼠、蚊、蝇、蜚蠊)的种群构成、季节消长规律,以及携带病原体的情况,为制定防治措施及防控虫媒传染病提供科学依据。方法 2013年8月-2015年3月,在广州白云机场候机楼二期建设区域内,按照施工情况,分为办公区、宿舍区、餐饮区、施工区和绿化带5个监测区域,每月定时、定点、定诱饵、定监测方法,对各个生境内的医学媒介生物进行监测。将捕获的医学媒介生物运送至本局综合实验室进行种属鉴定、数量统计、携带病原体检测。结果 (1)共捕获鼠形动物180只,经分类鉴定为2目2科7种,以臭鼩鼱为优势鼠种,占51.66%;2013年11月鼠形动物的密度最高,为6.04%;办公区的密度最高;对180份鼠心鼠肺样本进行鼠疫和流行性出血热的检测,阳性样本数为0。(2)共捕获成蚊537只,经分类鉴定为1目1科3种,以白纹伊蚊为优势种,占79.14%;2014年7月的成蚊密度最高,为21.56只/人工·h;2013年,室内的成蚊密度高于室外。(3)共捕获蝇类7 067只,经分类鉴定为1目4科25种,以大头金蝇为优势种,占41.36%;2013年10月的蝇类密度最高,为245.10只/笼;办公区的蝇类密度最高;对56组1 120只蝇类进行携带病原体的检测,检出条件致病菌15种。(4)共捕获蜚蠊175只,经分类鉴定为1目2科4种,以德国小蠊为优势种,占94.29%;2014年5月的蜚蠊密度最高,为6.6只/盒·夜;餐饮区的蜚蠊密度最高;对20组100只蜚蠊进行携带病原体的检测,检出条件致病菌3种。结论候机楼二期建设区域的医学媒介生物的密度较高,建议采取科学有效的防治措施,防止虫媒传染病的发生。
Objective To understand the population composition, seasonal variation and pathogenicity of medical vector organisms (rats, mosquitoes, flies and cockroaches) in the second phase of Guangzhou Baiyun Airport terminal building and to provide evidences for the prevention and control of zoonosis Disease provides a scientific basis. Methods From August 2013 to March 2015, in the second phase of the Guangzhou Baiyun Airport terminal construction area, five monitoring areas were divided into office area, dormitory area, dining area, construction area and green belt according to the construction conditions. Month time, fixed-point, bait, set monitoring methods, monitoring of medical media organisms in various habitats. The captured medical vectors will be transported to our integrated laboratory for species identification, quantitative statistics and pathogen detection. Results (1) A total of 180 mouse-shaped animals were captured and classified into 2 orders, 2 families and 7 species, with 51.66% of stinkbugs dominated. In November 2013, the density of rat-shaped animals was the highest (6.04% ; The density of the office area was the highest; the plague and epidemic hemorrhagic fever were detected in 180 rat heart-lung samples, and the positive number of samples was 0. (2) A total of 537 adult mosquitoes were captured and identified as 1 orders, 1 families and 3 species, with Aedes albopictus as the dominant species, accounting for 79.14% of the total mosquitoes. The highest adult mosquito density was 21.56 / artificial h; indoor adult mosquito density was higher in 2013 than in the outdoors. (3) A total of 7 067 flies were captured, identified as 1 orders, 4 families and 25 species, with the dominant flies as dominant species, accounting for 41.36%; the highest flies density was 245.10 / cage in October 2013; The density of flies in the office area was the highest. The pathogen was detected in 120 flies in 56 groups and 15 pathogenic bacteria were detected. (4) A total of 175 cockroaches were captured and identified as 1 orders, 2 families and 4 species. The dominant species was Blattella germanica, accounting for 94.29% of the total. Cockroach density was the highest in May 2014 at 6.6 / box · night ; The cockroach density in dining area was the highest; the pathogen was detected in 100 cockroaches in 20 groups, and 3 kinds of pathogenic bacteria were detected. Conclusion The density of medical vector organisms in the second phase of the terminal building is relatively high. It is suggested that scientific and effective prevention and control measures be taken to prevent the occurrence of zoonotic diseases.
