All Theses
Diplectrona modesta Banks 1908 (Trichoptera: Hydropsychidae) is a common inhabitant of streams across eastern North America. This species is well known and used often in biomonitoring studies. Experts in the field have long noted the morphological variation in larval head color and patterns as well as the species presence in many different types of habitats, such as springs, seeps, streams, and some small rivers. This study examines the species both morphologically and molecularly using mitochondrial and nuclear genes in order to determine if the species is a complex of several species or one highly variable species. DNA sequencing using the …

Insect Diversity And Pest Status On Switchgrass Grown For Biofuel In South Carolina, Claudia Holguin
All Theses
Switchgrass (Panicum virgatum L.) has tremendous potential as a biomass and stock crop for cellulosic ethanol production or combustion as a solid fuel. The first goal of this study was to assess diversity of insects in a perennial switchgrass crop in South Carolina. A three-year study was conducted to sample insects using pitfall traps and sweep nets at the Pee Dee Research and Education Center in Florence, SC, from 2007-2009. Collected specimens were identified to family and classified by trophic groups, and predominant species were identified. The diversity and density of weeds in the field during the establishment year (2007) …
