We used the Photonic Fence Monitoring Device (PFMD) to evaluate orientation by Musca domestica (Diptera: Muscidae), and Calliphora vicina (Diptera: Calliphoridae) to the Zevo Trap Model 3. The PFMD’s dual cameras record infrared light (IR) reflected from a wavelength-specific fabric; insects in front of the fabric do not reflect IR at the same wavelength and are tracked in three dimensions as flying or walking objects. The plug-in Zevo Trap emits ultraviolet and blue light from behind an opaque shield; attracted insects enter the space between the shield and the wall and are trapped on a sticky cartridge facing the wall. Experiments (N = 10) with groups of approximately 40, 1-7-day-old mixed-sex flies of each species were conducted in a large arena. Minimal responses occurred with overhead lighting on and the trap off. With the overhead lighting off, mean first catch of both species occurred within 5 min after the trap was turned on; after 1 h, 33.1% and 41.8% of M. domestica and C. vicina, respectively, had been caught. House flies flew toward the trap, many approaching from below, while C. vicina apparently walked outside the field of view of the PFMD until they appeared on the vertical reflective surface, and then walked toward the trap from all directions. Our results show that the Zevo Trap is effective in capturing flies and indicate that flies with differing orientation behavior can be captured.
