城市夜间人造光污染对植物和动物的生态、行为和生理产生了深远的影响。此外，这种广泛存在的环境污染物有可能通过改变传播疾病的昆虫的季节性动态而对人类和动物健康产生负面影响。由于白昼短，雌性北方家蚊进入越冬休眠或滞育。在滞育期间，雌蚊从繁殖中转移能量，停止吸血，不再传播疾病。我们证明，暴露于微弱的ALAN（类似于4 lx）会导致雌蚊避免滞育并变得繁殖活跃，因为这些雌蚊获得较少的脂肪含量，发育出更大的卵泡，吸收脊椎动物的血液，并产生可存活的卵和幼虫。我们的研究结果表明，在城市等高度光污染地区，蚊子可能会在季节后期积极繁殖和叮咬，从而延长城市居民的疾病风险期。我们的研究结果表明，在模拟蚊子丰度、疾病风险以及决定温带地区蚊子监测和控制应持续多长时间时，应该考虑ALAN。
Urban light pollution caused by artificial light at night (ALAN) profoundly affects the ecology, behavior, and physiology of plants and animals. Further, this widespread environmental pollutant has the potential to negatively impact human and animal health by changing the seasonal dynamics of disease-transmitting insects. In response to short days, females of the Northern house mosquito enter an overwintering dormancy, or diapause. While in diapause, female mosquitoes divert energy away from reproduction, cease blood-feeding, and no longer transmit disease. We demonstrate that exposure to dim ALAN (similar to 4 lx) causes female mosquitoes to avert diapause and become reproductively active, as these females acquired less fat content, developed larger egg follicles, imbibed vertebrate blood, and produced viable eggs and larvae. Our findings suggest that mosquitoes in highly light-polluted areas such as cities may be actively reproducing and biting later in the season, thereby extending the period of disease risk for urban residents. Our results suggest that ALAN should be considered when modeling mosquito abundance, disease risk, and when deciding how long mosquito surveillance and control should persist in temperate regions.
