【摘要】：为了解天津市流行性乙型脑炎传播媒介环境分布,于2009—2014年采用灯诱法对流行性乙型脑炎传播媒介的密度、种类构成及季节消长进行调查,对2010—2014年捕获的成蚊样品以逆转录-聚合酶链式扩增(RT-PCR)进行病原学检测。结果显示,2009—2014蚊虫年平均密度分别为12.48、16.64、18.82、11.09,8.99、6.36只/(h·灯),淡色库蚊为优势种群,2009—2014年占93.0%~98.2%,流行性乙型脑炎传播媒介在天津全境存在,2010年检测出病毒携带为G1型。
[Abstract]:In order to understand the distribution of epidemic encephalitis B transmission media in Tianjin, the density, species composition and seasonal variation of epidemic encephalitis B transmission media were investigated by lamp inductive method in 2009-2014. The results showed that the average annual densities of mosquitoes in 2009-2014 were 12.48-16.64,18.82nil 11.09nb 6.36 / r / h 路lamp, respectively. Culex pipiens pallens was the dominant population in 2009-2014 (93.0% 98.2%), and Japanese encephalitis was 98.2% (P < 0.05), while the population of Culex pipiens pallens was the dominant species in 2009-2014. The results showed that the annual average densities of mosquitoes were 12.48% and 16.64%, respectively. The virus was detected as G 1 type in 2010.
