Investigate The Ecological Characteristics Of Anopheles Anthropophagus In Hengqin Island Of Zhuhai And Screen The DNA Differences Of An.anthropophagus Between The Island And Mainland By RAPD

Backgroud: Anopheles anthropophagus is very important in transmitting Infectious diseases, such as malaria , filariasis. Anopheles anthropophagus is distributed in Hengqin island and Pingsha mainland of Zhuhai .The Anopheles anthropophagus density in Hengqin island is very huge, malaria epidemic in zhuhai is associated to large scale basic construction, In 1990's many odd job worker flushed in zhuhai to participate in construction of western district resulting in malaria epidemic.Hengqin island is near to Macao ,It's special geographic site attract most tourists ,Now, Hengqin island faces another round construction ,To avoid malaria epidemic, It's urged to investigate the ecological characteristics of Anopheles anthropophagite in Hengqin island .Objective:To find what reason lead to the huge density of Anopheles anthropophagus in Hengqin island and To investigate the ecological characteristics of Anopheles anthropophagus in Hengqin island .Methods: ecological investigation and statistic methods.Results and conclusions: the reasons lead to huge density:One. Natural characteristics lead to huge density.Second. Special breeding ground lead to huge density.Third. No using pesticides lead to huge density.The fourth. Anopheles anthropophagus in Hengqin island can bear the salt water than other mosquito lead to huge density.Both bovine blood and human blood are the favorites of the An. anthropophagus, especially the human blood.
