We investigated the role of socio-economic factors in the proliferation of mosquito vectors in two adjacent but socio-economically contrasting neighborhoods in Baton Rouge, LA, USA. We surveyed mosquito larvae habitat, mosquito larvae, and adult mosquitoes during the summer of 2020. We also evaluated the number of requests for mosquito abatement services in the years preceding the study for each area. While we did not find differences in terms of the most abundant species, (F = 0.329, = 0.57), we did find a higher abundance of mosquito habitats, particularly discarded tires, as well as larvae (z = 13.83, < 0.001) and adults (F = 4.207, = 0.049) of the species in the low-income neighborhood. In contrast, mosquito abatement requests were significantly higher in the high socio-economic neighborhood (z = -8.561, < 0.001). This study shows how factors such as adjudicated properties, discarded tires and pest abatement requests can influence the abundance of mosquito vectors, disproportionately affecting low-income groups. This study also highlights how spp. may be better indicators than spp. of socio-economic differences between nearby neighborhoods, due to their short flight range and habitat preferences, and this should be considered in future studies attempting to detect such disparities in the future.
我们调查了社会经济因素在美国路易斯安那州巴吞鲁日两个相邻但社会经济对比鲜明的社区中蚊子传播媒介扩散的作用。我们在 2020 年夏天调查了蚊子幼虫栖息地、蚊子幼虫和成年蚊子。我们还评估了研究前几年每个地区要求进行蚊虫防治服务的次数。虽然我们没有发现最丰富的物种存在差异（F = 0.329， = 0.57），但我们确实发现了更多的蚊子栖息地，特别是废弃轮胎，以及幼虫（z = 13.83， < 0.001）和成虫（F = 4.207， = 0.049）的物种 在低收入社区中。相比之下，高社会经济社区的蚊虫防治请求明显更高（z = -8.561， < 0.001）。这项研究表明，诸如被判定的财产、废弃轮胎和害虫防治请求等因素如何影响蚊子传播媒介的丰度，不成比例地影响低收入群体。这项研究还强调了 spp. 如何可能比 spp. 更能反映附近社区之间的社会经济差异，因为它们的短飞行范围和栖息地偏好，在未来试图检测此类差异的研究中应考虑到这一点。
