Nowadays, food dyes obtained from herbal, animal, microbial and mineral sources are widely used as food additives. In this study, the toxic effects of three different natural food dyes (carmine, turmeric and annatto) on 72 +/- 4 h larvae of Oregon-R wild type of Drosophila melanogaster were investigated. For this purpose, four different application doses (50, 75, 100, 125 mg mL(-1)) were chosen by means of preliminary studies. It was determined that larval mortality increased with increasing concentration in the application groups and the toxicity order was carmine > turmeric > annatto. It was observed that the survival rate was highest in the control with 98% and lowest in 125 mg ml(-1) carmine with 16%. In addition, the average lifespan of the adult individuals obtained from third instar larvae was also studied. While the average lifespan was 40.88 +/- 1.44 days in the control group, these values were 10.81 +/- 0.55-23.90 +/- 1.27 days in the carmine group, 15.00 +/- 0.80-22.42 +/- 1.43 days in the turmeric group and 10.33 +/- 1.03-35.68 +/- 1.54 days in the annatto group, respectively. According to the obtained results, when both the developmental period from larvae into adults and the lifespan of the developing adults were compared with the control group, the food dyes were found to be toxic and the toxicity order of carmine > turmeric > annatto was identified.
