Abstract

To evaluate the influence of ecological migration village construction on mosquito vector populations and mosquito-borne diseases in southern Yunnan Province. Two vicinal villages in Mengla County, the southern part of Yunnan Province, a native village, and a newly built village, were selected as study sites. Malaria and Japanese Encephalitis vector mosquito population divergence between the two villages were studied. Malaria and Japanese Encephalitis (JE) cases in the two villages were also compared. Anopheles minimus was the dominant population in houses in the newly built village, and An. jeyporiensis dominated the native village. Accordingly, there were nine malaria cases in the new village compared with zero cases in the native village. Culex tritaeniorhynchus, the chief JE vector in the study area, displayed no difference between the two villages; however, there was a higher density of the local secondary JE vector (Cx. pseudovishnui) in the native village than in the new one. The JE cases in the villages corresponded to zero. From the vector-borne disease perspective, our results suggest that local community should pay more attention to malaria and An. minimus during the construction of an ecological migration village in the new Chinese Western Developing Plan (CWDP) in southern Yunnan Province.

云南南部生态移民村建设对病媒蚊及蚊媒疾病的影响

摘要

评价生态移民村建设对滇南地区蚊媒种群及蚊媒疾病的影响。选择云南省南部勐腊县的两个邻近村庄、一个原生村和一个新建村作为研究地点。研究了两个村庄之间疟疾和日本脑炎媒介蚊子种群的差异。还对两个村庄的疟疾和日本脑炎（JE）病例进行了比较。新建村房屋中以微小按蚊为优势种群，按蚊为主要种群。jeyporiensis在这个村庄占主导地位。因此，新村有九例疟疾病例，而原村则为零例。研究区乙脑的主要媒介三带喙库蚊在两个村庄之间没有表现出差异；然而，原村的当地二级乙型脑炎媒介（ Cx.pseudovishnui ）密度高于新村。各村乙脑病例为零。从媒介传播疾病的角度来看，我们的结果表明当地社区应更加关注疟疾和疟疾。云南省新西部大开发生态移民村建设中的最小化。
