25.3%). In the world, the main vector An. minimus is mainly found in the mountainous forest, and this study result is completely consistent with this finding. In Thailand, An. minimus is one of the main malaria vectors. Many studies showed that they were present in most of the mountainous areas nationwide, and overlapped the distribution of An. harrisoni in some places [80]. In Vietnam, although the environment is changing and insecticides are continuously used in health and agriculture sectors for a long time on a large scale, An. minimus is still present in almost survey sites in midlands and mountainous areas nationwide, especially in the North. Our finding is also consistent with the study on the distribution of malaria vectors in the period of 2003-2012 by Vu Duc Chinh, in which An. minimus was found at 119 points all over the country, all of which were mountains and forests [5].
