The project "Alternative mosquito control by adult traps" (AIDA) is part of the research network "Epidemiology and Prevention of West Nile Virus Infection in Germany" (EPISODE). In the subproject AIDA, studies will be conducated at different locations in the main circulation area of West Nile virus (WNV) in eastern Germany (Saxony, Saxony-Anhalt, Berlin). Two mosquito control strategies are tested in the field. At all sites adult traps will be set up. At some sites, in addition to adult traps, control (B.t.i.)/removal from breeding waters will be conducted. The success of adult population reduction per site will be evaluated by parallel surveys in breeding waters and artificial resting places. At the same time, systematic sampling of breeding waters allows identification of the main breeding sites for mosquitoes of the genus Culex as main vectors of West Nile virus. Finally, in a dialogue workshop of the subproject, the collected expertise concerning zoonotic infectious diseases will be discussed including the public health service, in order to jointly develop future for the prevention of WNV.
