1a.Objectives (from AD-416):
To devise innovative methods for the suppression of insects that transmit diseases to U.S. military deployed abroad.
1b.Approach (from AD-416):
Identify and test compounds with insecticidal activity that makes them especially beneficial in the rapid control of mosquitoes, flies, and other arthopods responsible for carrying disease agent. Devise innovative means of applying control agents especially suited for use in combat or deployment conditions. Identify and test new classes of topical and area repellents for use by troops.
This project is being conducted under the DoD Deployed WarFighter Protection Program. The goal of the project is to evaluate the effectiveness of sprayers and methods used to make adult and barrier treatments for control of pests that transmit human diseases in military settings. In FY 2013, several sprayers were evaluated for spray droplet size. Each was tested using generic oil and water spray solutions across the full operational ranges of spray pressure, nozzle setting, and flowrate. Over the life of this project, much new knowledge was gained that will be of value in protecting military personnel from biting insects and from arthropod-transmitted diseases. More than 80 different spray systems were intensively evaluated and tested. Data from these tests were incorporated into a smartphone application that will be made available to appropriate users. Mortality of adult mosquitoes in bioassay cages was definitively assessed. A World Health Organization (WHO) test stand for compression sprayers was designed and tested. This test stand is being used by the U.S. Navy Entomology Center of Excellence to evaluate a variety of sprayers following WHO testing guidelines. Work by this project will lead to more accurate and effective spray applications in military settings. This project expired in FY 2013, but the work is being continued and expanded upon by the sister project 6202-22000-028-14I.
