130615-F-MJ178-001 Joint Base Charleston – Weapons Station, S.C. – Numerous saltwater marsh mosquito cover the leg of an individual’s Airman Battle Uniform near an area known as the spoils site here, June 15, 2013. Only female mosquitoes bite and once they are full, they lay their eggs, multiplying the number of mosquitos in the area. The 30-acre spoils site is known to produce approximately 40-million mosquitoes per acre, or 1.2 billion of the pest insects, annually. The Air Force Reserve’s 910th Airlift Wing Aerial Spray Unit, based at Youngstown Air Reserve Station Ohio, conducted spraying operations here, June 15, 2013 to control the population of the disease-carrying pest insects at the installation. The 910th’s 757th Airlift Squadron is home to the Department of Defense’s only large-area, fixed-wing aerial spray capability. U.S. Air Force photo by Tech. Sgt. Rick Lisum.
