目的掌握南昌市蚊虫种群分布、密度消长以及蚊媒疾病发生情况,并对蚊媒疾病发生的风险进行评估。方法蚊种调查采用灯诱法,蚊媒疾病监测采用专项疾病监测方案;风险评估参照曾晓芃的病媒生物风险评估体系。结果城镇是以致倦库蚊为优势种群,农村是以三带喙库蚊为优势种群;3年蚊密度为5.73只/(灯.h),6-9月出现高峰值;3年疟疾发病逐年升高,2007-2010年乙脑均无发病,登革热无发病也无输入性病例。结论南昌市主要蚊媒疾病疟疾、乙脑、登革热2011年发生危害风险水平均为1级,可忽略水平,但仍要加强和完善蚊媒疾病监测工作。
Objective To understand the distribution of mosquitoes, the growth of density and the occurrence of mosquito vectors in Nanchang and assess the risk of mosquito-borne diseases. Methods The mosquito species survey was conducted using light-induced method, mosquito-borne disease monitoring using a special disease monitoring program; risk assessment refer to Zeng Xiaoxian vector bio-risk assessment system. Results Culex pipiens quinquefasciatus was the predominant population in town and Culex tritaeniorhynchus was the predominant population in rural areas. The mosquito density was 5.73 / (lamp · h) in 3 years, and peaked in June-September. The incidence of malaria was 3 years Increased, 2007-2010 no incidence of Japanese encephalitis, no incidence of dengue nor imported cases. Conclusions The main mosquito-borne diseases of malaria, JE and Dengue in 2011 in Nanchang are all at level 1 with negligible risk. However, monitoring of mosquito-borne diseases should be strengthened and perfected.
