[Development and evaluation of new methodologies to test the attractiveness of Chrysomya megacephala (Fabricius) (Diptera: Calliphoridae) to visual stimulation by colors in laboratory conditions].
Three methodologies evaluated the attractiveness of Chrysomya megacephala (Fabricius) to colors (red, green, black, white, blue and green) using arena, fan and rectangle-shaped devices. Seven to 15 repetitions/10 insects were carried out, except for the arena trial (1 insect/repetition). In the first arena trial, adults showed significant differences in the second (green>red) and third landings (red>green and black). In males black>red were significantly different. In the second arena trial, only males did. In the fan trial, yellow and blue were significantly different for males, and red for females. In the rectangular trial, no significant difference was observed. Varied attractiveness occurred due to external and behavioral influences in dipterans.
