鲜为人知的是，关于主要蚊子繁殖地（源）和邻近（汇）的异质景观环境之间的比较源-汇关系。这些关系的探索可能提供独特的见解的公用事业的开放空间缓冲区的缓解策略，目前正在考虑由城市规划者，以减少蚊子和人类之间的接触。我们调查了一个高生产力的蚊子栖息地和邻近的住宅（发达）和农村（未开发）的沿海环境之间的源-汇关系。我们的研究结果表明，源汇关系不受环境的影响。这一结论得到了所有调查环境中观察到的盐沼蚊子日丰度的高水平同步性的支持（β = 0.67-0.79，P < 0.001）。尽管每个被调查的环境都是独特的，而且它们之间的开阔水域和陆地距离很远（2.2-2.6公里），但这种同步性还是发生了。诱捕器捕获量，我们解释为预期的蚊子叮咬滋扰，在住宅和农村沿海景观都很高（309.4 +/- 52.84和405.3 +/- 62.41蚊子/天）。这些观察结果表明，现有的和计划中的开放空间缓冲区将不会减少高度流浪盐沼蚊子造成的叮咬负担。这加强了对经验知情的规划指导方针的需要，这些指导方针提醒城市规划者注意人类住宅侵占靠近高度脆弱的蚊子栖息地的土地的真实的风险。
Little is known regarding the comparative source-sink relationships between primary mosquito breeding sites (source) and neighboring (sink) environments in heterogeneous landscapes. An exploration of those relationships may provide unique insights into the utility of open-space buffer zone mitigation strategies currently being considered by urban planners to reduce contact between mosquitoes and humans. We investigated the source sink relationships between a highly productive mosquito habitat and adjacent residential (developed) and rural (undeveloped) coastal environments. Our results suggest that source-sink relationships are unaffected by environment. This conclusion is supported by the high level of synchronicity in daily saltmarsh mosquito abundance observed among all surveyed environments (beta = 0.67-0.79, P < 0.001). This synchronicity occurred despite the uniqueness of each surveyed environment and the considerable distances of open water and land (2.2-2.6 km) between them. Trap catches, which we interpret as expected mosquito biting nuisance, were high in both residential and rural coastal landscapes (309.4 +/- 52.84 and 405.3 +/- 62.41 mosquitoes/day, respectively). These observations suggest that existing and planned open-space buffer zones will do little to reduce the biting burden caused by highly vagile saltmarsh mosquitoes. This strengthens the need for empirically informed planning guidelines that alert urban planners to the real risks of human residential encroachment on land that is close to highly vagile mosquito habitat.
