摘要:

【摘要】 目的 掌握宁波市蚊虫季节消长情况,为蚊虫防制提供科学依据。方法 采用人工小时法和灯诱法调查成蚊,定期观察积水容器蚊幼虫孳生情况。结果 2006-2008年室内共捕获成蚊7495只,密度指数为69.40只/人工小时,雌雄比为1∶1.54;其中淡色库蚊占99.17%,白纹伊蚊、中华按蚊、三带喙库蚊分别占0.49%、0.20%、0.13%;成蚊密度高峰期分别为6-7月和10-11月。室内捕获栖息成蚊7886只,雌雄比为1∶1.83;其中淡色库蚊占99.35%,白纹伊蚊、中华按蚊、三带喙库蚊分别占0.33%、0.14%和0.18%。城区放置诱蚊灯312个,捕获成蚊11 881只,雌雄比为1.09∶1,平均密度指数为3.17只/(灯·h),公园、居民区、医院密度指数分别为6.27、2.10、1.16只/(灯·h),以公园密度指数最高;淡色库蚊为优势种,占90.60%,三带喙库蚊、白纹伊蚊、中华按蚊、其他蚊种分别占8.73%、0.36%、0.17%和0.14%;密度高峰期分别为6-7月和10-11月。农舍放置诱蚊灯71个,捕获成蚊3078只,雌雄比为4.76∶1,平均密度指数为3.61只/(灯·h);三带喙库蚊为优势种,占73.91%,淡色库蚊、中华按蚊、白纹伊蚊分别占20.47%、3.54%、1.23%,其他蚊种占0.84%;密度高峰期为7-8月。采集幼虫(蛹)23 912条,平均1992.67条/个容器,白纹伊蚊、淡色库蚊分别占75.17%和24.42%,其他蚊种占0.41%;5-9月为密度高峰期。结论 宁波市蚊虫季节消长变化明显,要加强蚊虫孳生地的治理、灭蚊防蚊和疫苗接种工作,防治蚊媒传播疾病的发生。

 【Abstract】 Objective To know the seasonal change of mosquito in ningbo, and provided scientific basis for the mosquito control. Methods The landing biting method and light trap were used to the surveillance of mosquito, and mosquitoes breeding sites were inspected regularly. Results A total of 7495 mosquitoes were captured indoor during 2006-2008. Mosquito density index was 69.40/man·hour, and the ratio of male and female was 1∶1.54. Culex pipiens pallens accounted for 99.17%, and Aedes albopictus, Anopheles sinensis and Cx. tritaeniorhychus accounted for 0.49%, 0.20% and 0.13% respectively. The peak of adult occurred usually from June to July and October to November. As many as 7886 resting mosquitoes were captured indoor habitat and the ratio of male and female was 1∶1.83. Cx. pipiens accounted for 99.35%, Ae. albopictus, An. sinensis and Cx. tritaeniorhychus accounted for 0.33%, 0.18% and 0.14%, respectively. About 312 lamps were placed in the urban, and 11 881 adult mosquitoes were captured. The ratio of male and female ratio was 1.09∶1, the average density index was 3.17/lamp·hour. The density index in the park was the highest with the value of 6.27 , followed by residential areas(2.10) and hospital (1.16). Cx. pipiens pallens was the dominant specie, accounting for 90.60%, Cx. tritaeniorhychus, Ae. albopictus, An. sinensis, and other species mosquitoes accounted for 0.36%, 0.17%, 8.73%  and  0.14%  respectively.  The  peak  occurred usually from June to July. There were 71 lamps placed in the farmhouse, and 3078 adult mosquitoes were captured. The ratio of male and female was 4.76∶1. The average density index was 3.61/lamp·hour. Cx. tritaeniorhychus was the dominant specie, accounting for 73.91%, followed by Cx. pipiens pallens (20.47%), An. sinensis (3.54%), Ae. albopictus (1.23%) and other mosquitoes species (0.84%). The peak of density occurred usually from July to August. There were 23 912 larvae (pupa) collected, and the container index was 1992.67 mosquito/container. Ae. albopictus and Cx. pipiens pallens accounted for 75.17% and 24.42% respectively, and the other mosquitoes species accounted for 0.41%. The peak of density occurred usually from May to September. Conclusion The seasonal fluctuation of mosquitoes was obvious in Ningbo, and it should put the emphasis on the mosquito control to control mosquito-borne disease especially the management of mosquito breeding sites
