                 Outbreak of Dengue haemorrhagic fever has currently been one of the major problems in Thailand and also affecting a large number of people in Rayong province, especially in the years 2002-2007.  The process of Dengue haemorrhagic fever control and prevention have been established by the Ministry of Public Health and carried out by health officers and village health or students volunteers.  This quasi-experimental study was to investigate the collaboration of village health volunteers to set up the approach process of Aedes aegypti larvae control by applying the village map.  The objectives included the efficiency of village map application to survey and control of Aedes aegypti larvae in Wang Chan district of Rayong province.  The experimental group  (Thambon) was namely, Payub Nai and Wang Chan with the comparison group of Chum Sang and Plong-Taeam, respectively.  The study was divided into 2 periods.  The first period (in 2006) was prior the experiment which the problems and the patterns to control the Aedes aegypti larvae were investigated (followed the way of Rayong provincial and Wang-Chan district health office.) The second period (in 2007) was to apply the village map to control Aedes aegypti larvae and collaborate with village health volunteers.  The process included data collections before and after experiments during both periods of the 2 groups.  The Aedes aegypti larvae indices before and after experiments were compared by the Z-test.  The results of this research indicated that after experiments in experimental group, (when differentiate comparison before and after experiments) the CI, HI and BI decreased significantly compared to previous experiments.  Moreover, the village health volunteers in the experimental villages could manage to find and control Aedes aegypti larvae in the villages and communities.  By using the village map as a tool in the control of Aedes aegypti larvae was shown to be efficient.  If the larvae were regularly found in any houses the village health volunteers, would designate household the as being unaware and incorporative in Aedes aegypti larvae control  and the volunteers themselves would then made a move to be responsible for weekly control.  If any house was free from Aedes aegypti larvae, the village health volunteers would let the house owners to still be in charge and be monthly evaluated.
