A portable suction-type fly-collecting apparatus has been developed and used extensively in connection with diarrheal disease studies in the Phoenix, Arizona, area. It was designed to facilitate rapid collection of domestic flies from interiors of inhabited dwellings. Conventional or special bait traps (Coffey 1948, Anon. 1952, Schoof 1952) would cause abnormal attraction of flies from extramural sources and create possible nuisances. Many sampled buildings were without electrical power to operate suction-type collecting equipment and use of cone or sweep nets (Maier and Dow 1949) was not practical because of the possibility of damage to household furnishings.
