Results of medical arthropod surveys in the natural conserve zone- Can Gio mangrove forests, Ho Chi Minh city

Background: Can Gio mangrove forest is bio-diversified area. There is few studies on medical arthropod in Can Gio mangrove forest until now. Objective: To study bio-diversified feature and identify species with disease transmitting role. Subject and Method: In 2007, medical arthropod surveys were conducted at 3 sites located in the natural conserve zone- Can Gio mangrove forest. A cross-sectional study was used. Results and Conclusions: A total of samples of 6178 individuals of medical arthropod belonging to 65 species have been collected, including 3 species of flea (Siphonaptera), 1 species of ticks (Ixodidae), 6 species of chiggers (Trombiculidae), 6 species of mites (Gamasoidea), 25 species of flies (Muscoidea) and 24 species of mosquitoes (Culicidae). They belong to 37 genus, 17 families, 3 orders (Siphonaptera, Acarina and Diptera), and 2 classes (Insecta and Arachnida). 20 species having epidemiological role were found in Can Gio mangrove forest. The rate of Anopheles epiroticus biting human at night indoor, outdoor and daytime indoor is rather high, especially at the end of dry season at centre of the forest.

Result of investigation on medical arthropod in some place along Ho Chi Minh road in Cao Bang province

Background: In the period 2006-2010, a investigation on medical arthropod has been conducted\r\n', u'Objective: 1) To determine species composition and distribution of medical arthropod. 2) To find species transmitted disease \r\n', u'Subject and method: The cross sectional, descriptive and analytic investigation was conducted in 3 communes along the Ho Chi Minh road in Cao Bang province. \r\n', u'Results and conclusion: : A total of 3.437 of samples of medical arthropod belonging to 96 species have been collected including: three species of flea (Siphonaptera), two species of tick (Ixodoidea), four species of chigges (Trombiculidae), ten species of mites (Gamasoidea), twenty four species of flies (Muscoidea), and fifty-three species of mosquito (Culicidae). They belong to 39 genuses, 17 families, 3 orders: (Siphonaptera, Acarina and Diptera); two classes (Insecta and Arachnida). \r\n', u'Some species having epidemiological role such as Aedes albopictus, Culex tritaeniorhyncus, Cx. quinquefasciatus, Cx. vishnui ... were predominant at all study sites. Anopheles minimus, the main malaria vector, was mainly collected in cattle- sheds in Truong Ha and Bach Dang communes. \r\n', u'
