| The dengue fever (DF), an acute infectious disease transmitted by Aedes mosquitoes, has been widely and dramatically spread around the world due to such problems as the urbanization, globalization, and insecticide resistance since the 1980s. Every year there are more than one million dengue cases and nearly 2.5 billion people are threatened by this disease. Ever since the epidemic broke out again in Guangdong Province, China, in 1978, the worsening epidemiological trends have appeared likely to continue and disperse to the northern regions. Because no vaccine or chemotherapy is currently available for the prevention or treatment of the DF, strengthening the vector surveillance and control remains the most effective preventive measures. The WHO places great emphasis on the research of new, sensitive vector surveillance methods. As a part of global strategy for prevention and control of DF and DHF, active surveillance of the dengue vector is emphasized and encouraged to improve the understanding of vector biology, behaviour and transmission dynamics, and, to better and validate operational tools for vector surveillance. This study (No. 2003B60127), originating from a startup program of the key laboratory of pathogen emergency examination of Guangdong Province in the Guangdong Center for Disease Prevention and Control, is a key scientific research project supported by the Department Technical and Scientific of Guangdong Province.The aims of this study are firstly to design and develope an effective Mosquito and oviposition trap (Mosq-ovitrap) for the dengue vector surveillance, according to the Aedes mosquitoes' ecological behavior of oviposition in a container after feeding on blood; secondly, to establish a scientific, effective, simply and workable surveillance method for monitoring the Aedes mosquitoes density and collecting the adult Aedes... |
