Water samples from 11 belowground stormwater treatment Best Management Practices (BMPs) were evaluated for their capacity to support rapid development of the West Nile virus (WNV) mosquito vector, Culex quinquefasciatus. The observed minimum development time from egg to pupa ranged from six to over 30 days. Concentrations of potential food resources (total(More)
Belowground stormwater treatment devices referred to as Best Management Practices (BMPs) can be persistent sources of Culex quinquefasciatus Say (Diptera: Culicidae) mosquitoes and in urban environments necessitate routine monitoring and insecticide treatment for control. The design of certain structural features of BMPs may discourage mosquito entry and(More)
Simulated stormwater management devices baited with alfalfa infusion were constructed to test conveyance pipe dimension and orientation as a potential deterrent to mosquito oviposition. Various configurations of pipe diameter, length, and orientation were evaluated based on egg raft counts. Field trials tested pipes of 1.3-, 5-, and 10-cm diam and 0-, 90-,(More)
Belowground proprietary stormwater treatment devices can produce mosquitoes, including vectors of West Nile virus. Elimination of vertical entry points such as pick holes in manhole covers may reduce the number of mosquitoes entering and reproducing in these structures. Plastic manhole dish inserts were evaluated as structural barriers against mosquito(More)
Belowground stormwater infrastructure has long been documented to harbor mosquitoes, including those capable of transmitting human disease pathogens (Harbison et al. 2010a). Culex quinquefasciatus Say is a widespread vector species found in the lower latitude regions of the world that is often associated with these subterranean habitats (Lines 2002,(More)
A widely recommended strategy to minimize mosquito production in structural stormwater Best Management Practices (BMPs) is to ensure they hold captured water for no more than 72 h. However, this standard may be overly conservative for many mosquito species found in urban environments and may impede or prevent the capacity of BMPs to fulfill more stringent(More)
Stormwater treatment systems (STS) intended to mitigate the potentially negative public health and environmental impact caused by urban runoff are highly conducive to mosquito production. Thirty-one STS, 15 aboveground extended detention basins (EDBs) and 16 proprietary belowground systems newly installed along State Route 125 in San Diego County, CA, were(More)
The tens of thousands of catch basins found in many urban areas are a primary target of local vector control agencies for seasonal application of extended-release larvicides. A concern with using larvicides in these structures is that active ingredients can be hampered by high flows, debris, and sediment, all of which are common to these structures. As such(More)
The North Shore Mosquito Abatement District applies extended release larvicides including methoprene-based Altosid® XR Extended Residual Briquets to approximately 40,000 catch basins in the southern half of the District's operational area at the beginning of each season. Treatments begin in May and typically again 9 to 10 wk later when larvicide efficacy(More)
