Lepidoptera have diverse uses for silk, ranging from cocoon construction to prey capture. However, most studies on silk have focused on model organisms such as the silkworm moth (Bombyx mori). I plan on studying the Indian Meal Moth (Plodia interpunctella), a grain pest that is found in Florida. The goal of this study is to look at the effects of inter-larval interactions on silk fiber quality. Inter-larval interactions are important because most P. interpunctella are reared in colonies. Understanding the impacts of larval interaction on silk production is essential for determining the genetic basis of silk diversity and will have applications in further studies of silk production and quality.
