Comparison between the Salt Lake City trap (SLC) and commercial ABC trap (Clarke Mosquito Control, St. Charles, IL) based on adult mosquito collection totals.

Bar graphs with I-bars as standard error of the mean. All pairings were not significantly different within their group.</p

1) Thermoforming plastic strip cut to a reasonable length to encircle your desired CO₂ cylinder.

2) Molding the plastic to the desired cylinder and allowing to cool to shape. 3) Riveting holster inside the ammo can and reinforcing the opposite edge with tape to protect batteries during use. (TIF)</p

A) Parts layout for the Salt Lake City (SLC) trap: [1]; eye-screws and clips [2]; #2 conduit hanger and a 6-v variable speed motor and 7.5-cm (3 in) propeller; 18-guage copper wire and battery clips [4]; 0.48 cm (3/16 in) tubing with airstone for CO2; and push-to-connect fitting to attach to a CO2 source of choice. B) Commercial ABC trap, distributed by Clarke Mosquito Control (St. Charles, IL).</p

Six different prototypes of traps during initial screening.

A) 3-piece base design developed using an entry funnel mounted to a computer case fan, then stacked with a second funnel for connecting a catch net; used for 3 trap designs: a 12-volt case fan (Tornado TD8038H, Vantec Thermal Technologies, Fremont, CA) and measured at 20-kph suction. A 6-volt case fan (Multifan S1 80mm, AC Infinity, Inc., City of Industry, CA) measuring at 12-kph suction was then used for two separate models: “Complex Airstone” containing a 5-mm mineral airstone (Jardin Stone, UXCell Co., Hong Kong, China) on the CO2 line (4-mm inner diameter standard aquarium tubing, Penn-Plax, inc., Hauppauge, NY) for dispersing a lure homogenously; and “Pore Dispersal” where the CO2 line was fitted directly to the fan. B) The Salt Lake City trap covered in the main manuscript. C) 3D-printed trap design shared by Mosquito Consulting Services based in New Zealand. D) Positive control of the ABC trap (Clarke Mosquito Control, St. Charles, IL). E) Comparison data with a minimum of 4 replicates each and using aggregate adult mosquito collections. Outliers are black points outside the range of the box whiskers. Blue points denote the mean and the central black bar reflects the median. (TIF)</p

Field sites allocated for testing in the wetland and scrub habitats approaching the Great Salt Lake.

Site 1 in the far west of the alkali mud flats outlying the Great Salt Lake. Site 2 near agricultural lands, in flood plans and salt shrub habitat. Site 3 with meadow seeps in freshwater wetlands. The shapefiles for the municipalities, states, country, and hydrography used for the creation of this map were extracted from United States Geological Survey (USGS) (https://basemap.nationalmap.gov/arcgis/rest/services/USGSTNMBlank/MapServer).</p

1) Rejected design for funnel shaped trap body.

2) Printing errors that occur when the bed and nozzle settings are not correct for your build. 3) Rejected, but suitable, bucket container option for transport. 4) Rejected, but suitable, toolbox container option for transport. (TIF)</p
