由于热带非洲疟疾的恶化，人们重新燃起了对蚊子幼虫栖息地进行环境管理的兴趣。环境管理计划通常是通过处理所有潜在的繁殖栖息地来实施的“全面”运动。相比之下，有针对性的环境管理是基于对蚊子生产力异质性的正确理解。然而，测量生产力的实地方法的缺陷阻碍了我们对蚊子生产力的理解。为了解决这些问题，我们制定了一个框架，栖息地为基础的干预措施，通过采用景观的方法来阐明蚊子生产力的机制。强调了大力定量估计生产率的重要性。提出了空间模型来研究蚊子生产力和产卵之间的相互关系。在我们看来。环境管理方法必须考虑到生产力的可变性，以努力提高这些方法的可行性、成本效益和可持续性，特别是在沿着其他疟疾控制措施时。
Interest in environmental management of mosquito larval habitats has been rekindled due to deterioration of malaria in tropical Africa. Environmental management programs were typically implemented as "all-out" campaigns by treating all potential breeding habitats. In contrast, targeted environmental management is based on a sound understanding of the heterogeneity in mosquito productivity. However, deficiencies in field methodology for measuring productivity hamper our progress in understanding of mosquito productivity. To address these issues, we develop a framework of habitat-based interventions by adoption of a landscape approach to elucidate mechanisms underlying mosquito productivity. The importance of vigorously quantitative estimation of the productivity is highlighted. Spatial models are proposed to examine the interrelationship between mosquito productivity and oviposition of gravid mosquitoes. In our view. environmental management approaches must take into account variability in productivity, in efforts to improve feasibility, cost-effectiveness, and sustainability of such approaches, particularly when implemented along with other malaria control measures.
