Our research objective is to measure catch efficacy of commercial light traps against variable levels of competing ambient light in urban environments. One hundred house flies were released inside an enclosed bioassay consisting of a screen cage, duct tunneling, and a large box enclosing UV light traps. Light traps were equipped with UV bulbs. Fluorescent work lights containing two (2) 40 watt bulbs were suspended above the bioassay providing ambient light. Flies were simultaneously exposed to UV light traps and competing fluorescent light. Five intensity levels of ambient fluorescent light were compared against a dark control. Tests were run for 4 hours, and catch efficacy was determined by the number of flies caught on trap glue boards. Irradiance and intensity levels of UV and ambient light were measured with a spectrometer.
