蚊子在城市景观中构成越来越大的风险，其中少年栖息地的空间异质性可以影响蚊子密度和叮咬活动的细尺度差异。我们研究了幼蚊栖息地的差异沿着一系列的城市基础设施废弃可以影响成年人的身体大小的入侵虎蚊，白纹伊蚊（Skuse）（双翅目：蚊科）。成年Ae.从马里兰州巴尔的摩的住宅区收集了3年（2015-2017年）的白纹伊蚊，这些住宅区的废弃程度不同，由门用木板封住的房屋比例定义。我们展示了女性的爱。从高废弃率的地点收集的白纹伊蚊明显大于从高收入、低废弃率的街区收集的。包括翅长在内的蚊子身体大小的差异已被证明反映了重要特征的差异，包括寿命和病媒能力。目前的工作表明，女性的大小异质性可能反映青少年栖息地的变异性在空间尺度上最相关的成年伊蚊扩散和人类暴露风险的城市景观。以前的研究表明，在贫困社区管理遗弃和废物问题的失败支持了更多的蚊子生产，这项研究表明，在这些相同的社区蚊子可以活得更长，产生更多的卵，并具有不同的病媒潜力。
Mosquitoes pose an increasing risk in urban landscapes, where spatial heterogeneity in juvenile habitat can influence fine-scale differences in mosquito density and biting activity. We examine how differences in juvenile mosquito habitat along a spectrum of urban infrastructure abandonment can influence the adult body size of the invasive tiger mosquito, Aedes albopictus (Skuse) (Diptera: Culicidae). Adult Ae. albopictus were collected across 3 yr (2015-2017) from residential blocks in Baltimore, MD, that varied in abandonment level, defined by the proportion of houses with boarded-up doors. We show that female Ae. albopictus collected from sites with higher abandonment were significantly larger than those collected from higher income, low abandonment blocks. Heterogeneity in mosquito body size, including wing length, has been shown to reflect differences in important traits, including longevity and vector competence. The present work demonstrates that heterogeneity in female size may reflect juvenile habitat variability across the spatial scales most relevant to adult Aedes dispersal and human exposure risk in urban landscapes. Previous work has shown that failure to manage abandonment and waste issues in impoverished neighborhoods supports greater mosquito production, and this study suggests that mosquitoes in these same neighborhoods could live longer, produce more eggs, and have different vector potential.
