From June to September, 2016, 100 catch basins in eight parking areas were monitored weekly for the presence of mosquito pupae in the operational area of the North Shore Mosquito Abatement District (NSMAD) located just north of Chicago, IL, U.S.A. Weekly results from these basins were compared to weekly samples taken from residential street catch basins, the most common type of catch basin treated seasonally by the NSMAD with larvicides. Over the 17 study weeks, residential street basins had a mean rate of productivity (pupae per basin-visit) 12 times that of parking area catch basins. The two parking area sites with the highest mean rate of productivity were associated with county forest preserves. Productivity in both street and parking area basins was positively associated with the presence of three or more deciduous trees within 20 m of basins and if they were located directly adjacent to curbs. Alternatively, productivity was negatively associated with the proportion of impervious surface within 10 m of basins and weekly rainfall. Findings suggest that reduced catch basin larvicide applications may be appropriate in many parking area sites.
2016年6月至9月，在美国伊利诺伊州芝加哥北部的北岸灭蚊区（NSMAD）作业区域，每周对八个停车场的100个集水池进行监测，以检查是否有蚊蛹。将这些集水池的每周监测结果与从住宅街道集水池采集的每周样本进行比较，住宅街道集水池是NSMAD季节性使用杀幼虫剂处理的最常见集水池类型。在17周的研究期间，住宅街道集水池的平均生产率（每次检查集水池发现的蚊蛹数）是停车场集水池的12倍。平均生产率最高的两个停车场地点与县森林保护区有关。街道和停车场集水池的生产率与集水池20米范围内有三棵或更多落叶树以及集水池是否紧邻路缘呈正相关。相反，生产率与集水池10米范围内不透水表面的比例和每周降雨量呈负相关。研究结果表明，在许多停车场地点减少集水池杀幼虫剂的使用可能是合适的。
