A study of the West Nile virus risk associated with “dry” water-detention basins in Central Illinois took an unexpected turn when land managers started mowing the basins. The mowing of wetland plants in basins that failed to drain properly led to a boom in populations of Culex pipiens mosquitoes, which can carry and transmit the deadly virus, researchers report.
Mowing wetland plants can increase populations of mosquitoes that carry the West Nile virus, researchers report.
