Knowledge of the interrelationship of mosquito communities and land use changes is of paramount importance to understand the potential risk of mosquito disease transmission. This study examined the effects of land use types in urban, peri-urban and natural landscapes on mosquito community structure to test whether the urban landscape is implicated in increased prevalence of potentially harmful mosquitoes. Three land use types (park, farm, and forest nested in urban, peri-urban and natural landscapes, respectively) in Klang Valley, Malaysia, were surveyed for mosquito larval habitat, mosquito abundance and diversity. We found that the nature of human activities in land use types can increase artificial larval habitats, supporting container-breeding vector specialists such as Aedes albopictus, a dengue vector. In addition, we observed a pattern of lower mosquito richness but higher mosquito abundance, characterised by the high prevalence of Ae. albopictus in the urban landscape. This was also reflected in the mosquito community structure whereby urban and peri-urban landscapes were composed of mainly vector species compared to a more diverse mosquito composition in natural landscape. This study suggested that good environmental management practices in the tropical urban landscape are of key importance for effective mosquito-borne disease management.

人类活动吸引了热带城市景观中的有害蚊子。

了解蚊子群落与土地利用变化之间的相互关系对于了解蚊子疾病传播的潜在风险至关重要。这项研究研究了城市，郊区和自然景观中的土地利用类型对蚊子群落结构的影响，以检验城市景观是否与潜在有害蚊子的流行有关。调查了马来西亚巴生谷的三种土地利用类型（分别位于城市，近郊和自然景观中的公园，农场和森林）的蚊虫幼虫栖息地，蚊虫数量和多样性。我们发现，人类在土地利用类型中的活动性质可以增加人工幼虫的栖息地，从而为白纹伊蚊等容器繁殖媒介专家提供了支持，登革热媒介。此外，我们观察到蚊子的丰度较低但蚊子丰度较高的模式，其特征在于Ae的高流行。在城市景观中的白化病。这也反映在蚊子群落结构中，与自然景观中更多样化的蚊子组成相比，城市和城市周边景观主要由媒介物种组成。这项研究表明，热带城市景观中良好的环境管理实践对于有效的蚊媒疾病管理至关重要。
