Sand fly control in Kenya with residual pesticide application on HESCO barriers. Abstract for the American Mosquito Control Association Meeting in Atlantic City, NJ on February 24 - 28, 2013. pg.35.Interpretive Summary:
                                Technical Abstract: US military operations in hot-arid regions still face significant impacts from mosquito and sand fly vectors of diseases. Personal protective measures (PPM) such as DEET or treated bed nets and clothing can reduce contact with disease vectors and nuisance insects; however, irregular use of PPM coupled with widespread substandard sanitation in operational environments result in routine exposure to insect threats. We investigated a technique using standard-issue military pest management spray equipment and pesticide formulation to reduce insect threat loads in a hot-arid region regardless of PPM. HESCO blast wall barriers are ubiquitous in current US military theaters of operation in Afghanistan and the Arabian Peninsula. HESCO units are constructed of a rugged cloth-like material on which we hypothesized a residual pesticide treatment would be effective and long-lasting. We applied an aqueous solution of '-cyhalothrin at the label rate using a backpack mist blower to small, enclosed structures made of HESCO units in a hot-arid region in western Kenya targeting local abundant populations of Phlebotomus sand fly vectors of Leishmania. Periodic samples cut from the treated material were shown to cause high mortality for at least 3 months against mosquitoes in laboratory bioassays, and the treatment also significantly reduced wild sand fly densities in traps placed inside the units in the field for at least 5 months post-treatment.
