本文评估了在斯里兰卡的一条天然河流中通过不同的水管理措施控制疟疾病媒的选择。在流中的水位和初级媒介按蚊culicifaces的未成熟阶段的繁殖之间的关联进行了调查，并讨论了使用现有的灌溉基础设施，以减少繁殖潜力的可行性。最可行的选择是实施一项管理程序，即定期从上游水库放水，以减少下游繁殖地的数量。本研究表明，在整个旱季，通过调节溪流水位高于20厘米，可以促进A.可显著减少库利氏体。干预措施对农业用水损失的影响有限，管理投入也将是最低限度的。然而，要使干预措施发挥作用，当地社区的高度支持是必不可少的，政府各部门之间也需要进行协商。(C)1998 Elsevier Science B.V.保留所有权利。
This paper assesses the options for control of malaria vectors through different water management practices in a natural stream in Sri Lanka. The association between water level in the stream and breeding of the immature stages of the primary vector Anopheles culicifacies was investigated and the feasibility of using existing irrigation infrastructure to reduce the breeding potential discussed. The most feasible option would be to implement a management routine where water is released periodically from an upstream reservoir to reduce the number of breeding sites downstream. This study indicates that by regulating the water level above 20 cm in the stream throughout the dry season the breeding of A. culicifacies could be significantly reduced. The intervention would have only limited impact on the water lost for agriculture and the management input would be minimal. However, for the intervention to work a high degree of support from the local community is essential and consultation between government departments needed. (C) 1998 Elsevier Science B.V.
