Today, that discovery is the basis of a new Drexel-backed startup, BioLogic Insecticide. Simon D. Kaschock-Marenda, now a freshman at Drexel in the College of Engineering, was 11 when he noticed that Drosophila melanogaster, commonly known as fruit flies, died much quicker when they fed on Truvia than on other sweeteners. His father, Daniel Marenda, PhD, professor of biology in the College of Arts and Sciences, was unconvinced at first.
