1 Testing Novel Mosquito Traps, Fairfax County, VA, 2010 Joshua Smith FairfaxCountyHealth Department

2 Background Saw new trap on Biogents website Could not find any published research on new trap Ordered 4 Mosquitaire traps from manufacturer in Germany Original quote in Euros Did not accept credit cards Tax forms

3 Background II Told of second new trap while waiting for paperwork to clear Cheaper and just as effective (according to manufacturer) Modified order Three Mosquitaire traps Three Mosquitito traps Original inquiry Receipt oftraps: 54 days

4 Methods Study Design Latin Square Trap Rotation Four days/week Four weeks Each trap at each location one day/week Rotate starting point each week

5 Week One Day 1 Day 2 Day 3 Day 4 Site 1 Site 2 Site 3 Site 4 Mosquitito Mosquitaire no CO 2 BGS Mosquitaire with CO 2 Mosquitaire with CO 2 Mosquitito Mosquitaire no CO 2 BGS BGS Mosquitaire with CO 2 Mosquitito Mosquitaire no CO 2 BGS Mosquitaire with CO Mosquitaire no CO 2 Mosquitito

6 Trap Locations ft 50 m Each morning, traps were rotated through the four trapping tapp gstato stations. s

7 Methods II Tarps placed above each trap site 12 V battery 24 hour trap period August September m apart and 2 10m in the woods

8 BG Sentinel CO 2 BG Lure Color contrast Convection currents Collects day andnight night feeding host seeking seeking mosquitoes

9 Mosquitaire [t]he most efficient trap against the Asian Tiger mosquito Sweetscent Visual cues Air currents Consumer version of BG Sentinel Does not require carbon dioxide Tested with and without CO 2

10 Mosquitito Developed for Asian Tiger mosquito Sweetscent Visual cues Air currents Sweetscent /Sweetskin Lure

11 Methods III Statistical Methods Log (x+1) transformation One way ANOVA Post Hoc Tukey s b, Games Howell
