The problem of inducing mutations holds a fascination for the scientist because no one has as yet adequately explained the cause of mutations in nature. In attempts to solve this riddle, X-rays have been used most extensively to induce mutations, but because of the recent discoveries regarding the powerful effect of chemicals and fungi produced chemical compounds upon tropical disease-carrying insects, this field of experimentation is being reinvestigated in the hope of clarifying still undefined phases of the subject.

The purpose of this experiment was to determine the capacity of different types of chemicals to produce mutations, the mutation rate and types of mutants obtained, and the tolerance of the insect, Drosophila melanogaster, to various concentrations of the chemicals.
