【摘要】：目的了解柳州市蚊类种群分布以及病毒携带情况,为蚊媒传染病防控工作提供科学依据。方法成蚊密度监测采用诱蚊灯法,白纹伊蚊专项监测采用诱蚊诱卵器法。利用聚合酶链式反应技术(Poymerase Chain Reaction,PCR)检测方法对收集到的蚊虫进行登革热病毒、乙型脑炎病毒核酸检测。结果柳州市2016年3-11月份共捕获9 535只雌蚊,以致倦库蚊为优势种群,占86.49%(8 247/9 535),其它依次为中华按蚊占6.50%(620/9 535)、骚扰阿蚊占4.16%(397/9 535)、白纹伊蚊占2.84%(271/9 535);成蚊密度高峰出现在5-6月份,8-9月份出现次高峰;诱蚊诱卵平均指数达20.45,公园平均指数最高25.40,花鸟市场最低6.26;共捕获到的8 247只致倦库蚊,用螺旋管分装成224份标本进行乙型脑炎病毒核酸检测,结果显示有9份为阳性,阳性率4.02%,阳性标本分布于牲畜棚及废品回收站监测点;对捕获到的271只白蚊伊蚊用螺旋管分装成14份标本进行登革热病毒核酸检测,结果均为阴性。结论柳州市蚊媒密度较高,在牲畜棚及废品回收站等场所蚊媒检出乙型脑炎病毒,存在发生蚊媒传染病流行风险,需要加强蚊媒传染病综合监测和防控措施。
[Abstract]:Objective to investigate the distribution of mosquito species and the status of virus carrying in Liuzhou City, and to provide scientific basis for the prevention and control of mosquito borne infectious diseases.Methods the density of adult mosquitoes was monitored by ovitor-lamp method, and the specific monitoring of Aedes albopictus was carried out with ovitator.Polymerase chain reaction (PCR) technique was used to detect dengue virus and Japanese encephalitis virus nucleic acid.Results A total of 9 535 female mosquitoes were captured in Liuzhou from March to November 2016, and Culex quinquefasciatus was the dominant population.Anopheles sinensis, Anopheles sinensis, Anopheles sinensis, Anopheles sinensis, Anopheles sinensis, Anopheles sinensis, Anopheles sinensis, Anopheles sinensis, Anopheles sinensis, Anopheles sinensis, Anopheles sinensis, Anopheles albopictus, Aedes albopictus, respectively.The ovulation average index of mosquito was 20.45, the average index of park was the highest 25.40, the market of flowers and birds was the lowest 6.26.The total of 8 247 Culex pipiens quinquefasciatus were detected by nucleic acid detection of Japanese encephalitis virus with 224 specimens in helical tube, the results showed that 9 were positive.The positive rate was 4.02, the positive specimens were distributed in livestock shed and waste collection station, and 14 samples of Aedes albopictus were separated into 14 samples by helical tube, the results were all negative.Conclusion the density of mosquito vector is high in Liuzhou City. The Japanese encephalitis virus is detected by mosquito vector in livestock shed and waste recycling bin. There is a risk of epidemic of mosquito borne infectious disease. It is necessary to strengthen the comprehensive surveillance and control measures of mosquito borne infectious disease.
