全球媒介传播疾病负担占人类传染病的 17% 以上。近年来，寨卡病毒和基孔肯雅病毒等以前不为人所知的病原体在全球范围内迅速扩张，凸显了了解人为变化如何影响媒介传播疾病的出现和蔓延的重要性。森林砍伐已被确定为影响媒介传播疾病流行的一种人为变化，尽管已经报道了森林砍伐对媒介传播疾病传播影响的对比情况。这些相互矛盾的发现可能归因于媒介传播疾病系统固有的复杂性，该系统涉及不同的媒介、宿主和病原体，具体取决于地理位置。目前的研究对森林砍伐和蚊子之间的联系进行了定量探索，蚊子是媒介传播疾病系统最重要的常见组成部分。对来自 12 个国家的 87 种蚊子的已发表实地研究数据进行分析后发现，大约一半的蚊子物种 (52.9%) 与森林砍伐的栖息地有关。在这些受森林砍伐青睐的物种中，与受森林砍伐负面影响的物种（27.5%）相比，被证实为人类病原体载体的比例要高得多（56.5%）。此外，作为多种人类病原体载体的物种都受到森林砍伐的青睐，包括班克罗夫特按蚊、达林按蚊、法劳按按蚊、富尼按蚊、冈比亚按蚊、亚纹按蚊、埃及伊蚊、警戒伊蚊、环吻库蚊和五纹库蚊。我们对媒介和非媒介物种的定量分析表明，森林砍伐的净效应有利于作为人类疾病媒介的蚊子，而反面也适用于非媒介物种。这些结果开始统一我们对森林砍伐和媒介蚊子之间关系的理解，这是量化土地利用变化（特别是森林砍伐）如何影响人类媒介传播疾病风险的重要一步。 (C) 2017 年 Gesellschaft Fur Okologie。由爱思唯尔有限公司出版。版权所有。
The global burden of vector-borne diseases accounts for more than 17% of infectious diseases in humans. Rapid global expansion of previously obscure pathogens, such as Zika and chikungunya viruses in recent years highlights the importance of understanding how anthropogenic changes influence emergence and spillover of vector-borne diseases. Deforestation has been identified as one anthropogenic change that influences vector-borne disease prevalence, although contrasting pictures of the effects of deforestation on vector-borne disease transmission have been reported. These conflicting findings are likely attributable to the inherent complexity of vector-borne disease systems, which involve diverse groups of vectors, hosts and pathogens, depending on geography. The current study represents a quantitative exploration of the link between deforestation and mosquitoes, the most important common constituents of vector-borne disease systems. Analysis of data compiled from published field studies for 87 mosquito species from 12 countries revealed that about half of the species (52.9%) were associated with deforested habitats. Of these species that are favored by deforestation, a much larger percentage (56.5%) are confirmed vectors of human pathogens, compared to those negatively impacted by deforestation (27.5%). Moreover, species that serve as vectors of multiple human pathogens were all favored by deforestation, including Anopheles bancroftii, Anopheles darlingi, Anopheles farauti, Anopheles funestus s.l., Anopheles gambiae s.l., Anopheles subpictus, Aedes aegypti, Aedes vigilax, Culex annulirostris, and Culex quinquefasciatus. Our quantitative analysis of vector and non-vector species, demonstrates that the net effect of deforestation favors mosquitoes that serve as vectors of human disease, while the obverse holds true for non-vectors species. These results begin to unify our understanding of the relationship between deforestation and vector mosquitoes, an important step in quantifying how land use change, specifically deforestation, affects human risk of vector-borne disease.
