Molecular Phylogenetic Analysis Of The Simulium Jenningsi Species-Group (Diptera: Simuliidae), Elizabeth Ann Alexander
Molecular Phylogenetic Analysis Of The Simulium Jenningsi Species-Group (Diptera: Simuliidae), Elizabeth Ann Alexander
Masters Theses
A molecular phylogenetic investigation was undertaken to identify species within the morphologically homogeneous Simulium jenningsi species group, a pestiferous group of 22 species of black flies restricted to the Nearctic region. Several species in this group have well documented medical and veterinary importance, most notably S. luggeri and S. jenningsi. Unfortunately, females are monomorphic, a conundrum given their pest status. The objective of this study was to examine the utility of molecular data in species identification, with obvious application to identification of pest females. Towards this end, we sequenced approximately 2 kilobases of sequence data from the mitochondrial (Cox …
A Revision Of Tomoceridae (Insecta: Collembola) In Great Smoky Mountains National Park And Southern Appalachians Using Morphological And Molecular Approaches, Kelly Lynn Felderhoff
A Revision Of Tomoceridae (Insecta: Collembola) In Great Smoky Mountains National Park And Southern Appalachians Using Morphological And Molecular Approaches, Kelly Lynn Felderhoff
Masters Theses
Large, heavily scaled tomocerid springtails (Collembola) are abundant in eastern forests, and are important components of the detrital food web. The genus Pogonognathellus predominates in the southern Appalachians While a number of well-delimited tomocerid species have been described, others have vague morphological boundaries and appear to be species complexes. Before this study began in 2005, four species were known to occur in Great Smoky Mountains National Park (GSMNP) and the surrounding Appalachians (P. bidentatus, dubius, elongatus, flavescens). Also occurring throughout the area is Tomocerus lamellifera, a widespread and distinctive species. The goals of this project were to …
Impact Of Imidacloprid And Horticultural Oil On Non–Target Phytophagous And Transient Canopy Insects Associated With Eastern Hemlock, Tsuga Canadensis (L.) Carrieré, In The Southern Appalachians, Carla Irene Dilling
Masters Theses
Hemlock woolly adelgid, Adelges tsugae Annand, is an exotic insect species dramatically reducing populations of eastern hemlock, Tsuga canadensis (L.) Carrieré, throughout the eastern United States. Systemic imidacloprid and horticultural oil are the two primary chemicals used to control infestations of the hemlock woolly adelgid. However, the effect of application timing (fall versus spring) and method on the translocation of imidacloprid throughout the canopy in addition to the quantity of imidacloprid translocated is unknown. Also, the potential effect of both imidacloprid and horticultural oil on non-target canopy insects is unknown. A study was initiated to determine the effect of application …
