The effects of chronic phenol exposure via diet on developmental stages of Drosophila melanogaster (Diptera: Drosophilidae)

In this study, the effect of phenol, on the developmental biology of D. melanogaster was investigated. For this purpose, definite concentrations of phenol (0.25, 0.5, 1.0, 1.5, 2.0, 2.5 mg/kg/100 ml medium) were added to the media of adult induviduals. In F-1 generation of phenol exposured parentals the time to metamorphosis was longer than that of control. In addition, the total number of offsprings was decreased and different phenotypic abnormalities were observed. The offsprings of F-1 generation were transferred to the Standard Drosophila Medium (not containing phenol) and F-2 generation was obtained. The times of metamorphosis of F-2 generation of the experimental groups (II-VI application groups) and the control group were 9-12 and 9 days, respectively. Furthermore, the number of offsprings was increased and the phenotyphic abnormalities decreased.
