Abstract: Objective To understand breeding water bodies and seasonal circle of mosquito larvae for mosquito control.Methods Ladle and container index methods.Results The larvae positive rate of large and middle size of breeding water bodies was 63.16%.Culex,Anopheles and Aedes mosquitoes larvae were found.Larvae were found in 8 of 11 kinds of water bodies.In large water bodies,larvaes growth peak was in June,the density index was 2.88 larvae per ladle.Among 5 different water bodies,the highest density was in kitchen gardens,and its density index was 2.36 larvae per ladle.Culex,Anopheles and Aedes larvae were all found in 4 different kinds of containers.The whole positive rate and density index were 36.06% and 77.03%,respectively,and the peak occurs in June.Conclusion The key time for mosquito control was in June,and the key areas were containers,ground water logging and dirty water.
