Background: Vietnam is one of eight countries with dengue fever / dengue hemorrhagic fever circulating seriously in the region. Some recent studies showed Mesocyclops dropping is one of effectively dengue fever/dengue hemorrhagic fever preventive approaches.\r\n', u'Objectives: To survey the distribution and role of mesocyclops in preventing dengue fever/dengue hemorrhagic fever in three communes in Thanh Hoa province.\r\n', u'Subjects and methods: The study was conducted in Dong Hai, Thanh Hoa, Hai Chau communes of Tinh Gia district, Nga Lien commune of Nga Son district. Research subjects are Mesocyclops collected in the artificial water containers and Adesaegypti mosquito larvae in water containers.\r\n', u'Results: Two species found are M.woutersi mesocyclops and M.thermo. M.woutersi exits in all of three local studied Mesocyclops rate in the water containers is 8.2%. Mesocyclops rate in water containers in Nga Son district is highest (13.26%) and in city is lower (13.26%). Of the experimental five species dropped on field, there are four species survived after a long-term period. Among them, M. Woutersi is highest (65.51%), M.aspericornis (15:52%). They breed and grow very fast, easy to adapt to natural conditions in Thanh Hoa.\r\n', u'Conclusion: The results show that Mesocyclops can be cultured in Thanh Hoa province.\r\n', u'\r\n', u'\r\n', u'
