Diet mediates many life history trade-offs and therefore is an important environmental component to consider. Because some organisms share food sources with humans, they encounter anthropogenic changes to their diet, such as genetically modified crops and chemical applications, which can contribute to additional complexity in their environment. To understand the effect of diet on the life history of the soybean looper, Chrysodeixis includens, we exposed larvae to several different food sources, including genetically modified soybean leaves and the pesticide spinosad. Significant differences in larval instar duration and timing of larval mortality among treatments were observed indicating that type of diet has complex effects on the life history of C. includens.
