Effects of sodium arsenite and chromium (ııı) chloride on sex ratio and some development properties of Drosophila melanogaster
Abstract :
In this research the effects of sodium arsenite and chromium (III) chloride on sex ratio, larval development and metamorphosis duration of Drosophila melanogaster adults have been investigated. In the research five concentrations below LC50 value (0.05, 0.5, 1.0, 2.5, and 5.0 ml) have been tested.Metallic solution has been applied by feeding to Drosophila melanogaster. Adults which developed in medium containing metallic solution have been studied through separating them as females and males. Totally 45163 individuals were counted by gender separation. With application of the two substances both separately and together, deviation from expected 1:1 sex ratio has been observed at some concentrations. Sex ratio has changed as an increase in ratio of female individuals and it has been found that male individuals were more sensitive to toxic effect during development. Larval development failed directly proportional to the concentration. Particularly in high concentrations, development ratio has decreased to 35-40 %. However, in metamorphic duration, no failure has been observed in both generations.
