  2. 2003 WNV PLAN • Comprehensive and integrated approach • Multiple agencies involved • MDA, MDCH, MDNR, MDEQ, MSU • Arbovirus Emergency Response Plan • Basis for local decisions/response • Communication is essential • Not a state spray program

  3. 2003 WNV PLAN • Surveillance • Horse Surveillance • Private Veterinarian Communication System • Testing animal specimens at MSU • Encourage vaccination of all horses • Encourage source reduction in environs • Encourage use of repellants • Domestic Animals • MSU may offer testing in 2003

  4. 2003 WNV PLAN Mosquito Surveillance Used to help local response planning Species Identification (Culex pipiens) Population density Breeding source locations (source reduction)

  5. 2003 WNV PLAN Mosquito Control Commensurate with risk Emphasize personal protection & source reduction

  6. 2003 WNV PLAN • Source Reduction • Reduce breeding sites to reduce mosquito larvae development (stagnant water) • Discarded tires, bird baths, small pools, or any container that will hold water • Communicate with residents, businesses & green space managers • Increase surface turbidity • may require state or federal permits • Filling ponds or wetlands not helpful

  7. 2003 WNV PLAN • Mosquito Population Reduction • Larvae control • Larviciding where breeding sites cannot be modified (i.e.: storm drains) • Use MDA registered pesticides • Options include biological control products • Follow label use directions • MDEQ approval may be necessary • Contact MDEQ at (517) 373-1320

  8. 2003 WNV PLAN • Mosquito Population Reduction • Adult Mosquito Control • Risk of disease transmission to humans • Targeted spraying as part of a comprehensive, integrated management plan • Decision based on all available surveillance information • Community spray programs regulated by MDA • communication, pre-notification or exclusion options • pesticide use, applicator certification, business licensing • MDNR administered lands and easements
