Adding a non-fluorescent dye, Rhodamine-B, to the adult diet of uzi fly, Exorista bombysis (Louis) has shown to be a useful method for marking the eggs for flight range experiments. The method is timesaving and the dye is safe to handle and the marked eggs are easy to detect. Files fed on the diet added with dye did not have much negative effect on adult mortality and fecundity, but egg hatchability was affected.
