Seasonal Abundance Of Mosquitoes (Diptera: Culicidae) At A High And Low Prevalence Site For La Crosse Encephalitis In Eastern Tennessee, Nathan David Caldwell

Masters Theses

La Crosse (LAC), a California (CAL) serogroup bunyavirus, is the most prevalent pediatric arboviral disease in the United States and accounts for virtually all encephalitis cases associated with CAL serogroup arboviruses. In Tennessee, USA, prior to the drastic increase of confirmed La Crosse (LAC) encephalitis cases in 1997, the sum of documented cases reported to the Tennessee Department of Health totaled 9. During subsequent years in Tennessee (1997 to 2003), an average of 12 cases has been reported annually. Approximately 62% of these reported cases have occurred in the months of July and August. The native, container-inhabiting mosquito Ochlerotatus triseriatus …

Examining Varroa-Resistant Honey Bee Queens From Commercial Breeders: Colony Productivity, Hygienic Behavior, Suppression Of Mite Reproduction, And The Relationship Of Juvenile Hormone Iii To Mite Abundance, Laura L. Bryant

Masters Theses

This research was conducted to assess the performance of commercially bred honey bee queens sold as resistant to the parasitic mite, Varroa destructor. The study’s objectives were to: 1) Compare honey and pollen stores and V. destructor infestation in colonies established with hybrid Russian, SMR, and control queens, 2) Determine levels of hygienic behavior and mite non-reproduction in the same colonies, and 3) Determine the relationship between juvenile hormone III in honey bee larvae and V. destructor reproduction.

In Part One, when honey, pollen, and V. destructor levels were measured, no significant differences were found among types of queens. …

Insect Fauna Associated With Eastern Hemlock, Tsuga Canadensis (L.), In The Great Smoky Mountains National Park, Stanley Earl Buck Iii

Masters Theses

Eastern hemlock, Tsuga Canadensis (L.), is an integral part of the forest system in eastern North America. These trees contribute to the biological diversity, environmental health, and economic stability of the regions that they inhabit by producing unique microclimates, cool shady recreational areas, and unmatched beauty. Information regarding the insect fauna associated with eastern hemlock is sparse and scattered with in the literature. Because of this, the insect fauna associated with eastern hemlock was assessed at four sites, representing new and old growth, and nine alternate sites in the Great Smoky Mountains National Park (GSM). Sites were sampled using malaise …
