摘　　要：目的了解南昌市蚊虫孳生的水体以及蚊幼虫的消长趋势,为制订灭蚊方案提供理论依据。方法勺捕法和容器指数法。结果大中型水体阳性率63.16%,库蚊、按蚊、伊蚊3种蚊属均有发现,11种水体中,8种水体曾发现有蚊幼虫孳生,大中型水体生长高峰在6月,幼虫密度为2.88条/勺,5种大中型水体蚊幼虫密度最高的是菜园水沟,密度为2.36条/勺。容器的阳性率为36.06%,4种容器中库蚊、按蚊、伊蚊3种蚊属均有发现,容器中生长高峰以6月最高,密度指数为77.03%,4种容器的阳性率以轮胎最高为40.76%。结论蚊虫控制工作的重点是在每年的6月,容器、地面积水、污水是治理的重点。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.
