From Field To Film: Mosquito Surveillance And Survey Of Us Adults' Knowledge And Attitudes Towards Arthropod-Borne Disease Vectors, Justine Laviolette
From Field To Film: Mosquito Surveillance And Survey Of Us Adults' Knowledge And Attitudes Towards Arthropod-Borne Disease Vectors, Justine Laviolette
Department of Entomology: Dissertations, Theses, and Student Research
Mosquito-borne disease is a public health challenge that warrants an active surveillance program for the identification of mosquito populations and the education of the public for prevention and protection against disease-transmitting arthropods. The communication of science to the public is necessary to prevent disease, change behavior, and promote a dialog between scientists and the public.
People are accustomed to high quality entertainment, which begs the question, “If we made science more entertaining, would the public be more interested?”
To address these issues, the objectives of this study are: 1) identify mosquito species and abundance at the US Meat Animal Research …
A Mixed-Methods Study Of Entomology Incorporation In U.S. Secondary Science Instruction, Erin M. Ingram
A Mixed-Methods Study Of Entomology Incorporation In U.S. Secondary Science Instruction, Erin M. Ingram
Department of Entomology: Dissertations, Theses, and Student Research
To encourage understanding and appreciation of insects, entomology education advocates have supported and encouraged K-12 teachers to integrate insects and insect-related content into formal science instruction. However, research examining how and why science teachers incorporate entomology into secondary science courses is limited.
A sequential explanatory mixed-methods research study was conducted to address this gap. The study was conducted in two phases. During the first phase, quantitative survey research was conducted with a representative sample of 254 U.S. secondary life science teachers. During the subsequent qualitative phase, follow-up interviews were conducted with a purposeful sample of 18 survey participants and an …
Using Adults To Monitor Rnai Susceptibility Of Western Corn Rootworm, Diabrotica Virgifera Virgifera Leconte, Field Populations, Matthew Welter
Using Adults To Monitor Rnai Susceptibility Of Western Corn Rootworm, Diabrotica Virgifera Virgifera Leconte, Field Populations, Matthew Welter
Department of Entomology: Dissertations, Theses, and Student Research
The western corn rootworm (WCR), Diabrotica virgifera virgifera LeConte, is the most damaging corn pest in the U.S. Corn Belt, costing producers over $1 billion annually in control and damage costs. Currently, corn producers rely on three control strategies for WCR management: crop rotation, chemical insecticides, and transgenic corn expressing Bacillus thuringiensis Berliner (Bt) proteins. Populations of WCR have evolved resistance to all of these tactics, limiting effective control strategies for producers. RNA interference (RNAi), is the newest mode of action developed for WCR management. In July 2017, the first RNAi plant-incorporated protectant (PIP) corn product was approved for production …
Promoting Bee Communities Through Habitat Enhancements On Public And Private Lands In Nebraska, Kayla A. Mollet
Promoting Bee Communities Through Habitat Enhancements On Public And Private Lands In Nebraska, Kayla A. Mollet
Department of Entomology: Dissertations, Theses, and Student Research
Wild and managed bees are the most effective pollinators, accounting for about 80% of the pollination of flowering plants and 75% of fruits, nuts, and vegetables in the United States (USDA, 2019; USFWS, 2019). An estimated 4,000 species of bees reside in North America, the majority of which are wild and unmanaged. Wild bee communities are critical for maintaining healthy ecosystems, as they sustain native flora that provides soil stability and habitat for other wildlife. In a changing landscape, floral enhancements on privately and publicly-owned lands may have great impact for improving habitat for pollinators across the United States. Planting …
A Descriptive Study Of Wild Bees (Hymenoptera: Apoidea: Apiformes) And Angiosperms In A Tallgrass Prairie Corridor Of Southeastern Nebraska, Katie Lamke
Department of Entomology: Dissertations, Theses, and Student Research
The presence of diverse bee communities in an ecosystem is vital for maintaining healthy plant communities, promoting habitat resilience, and supporting sustainable agricultural production and urbanization. Approximately 20,000 known species of bees exist worldwide and assist with the successful reproduction of nearly 80% of Earth’s flowering plants by providing pollination services. In the US, wild bee declines have led to increased monitoring efforts for bees but there remain critical data gaps in prairies of the Great Plains ecoregion. Specific to the Tallgrass prairie where only 1-3% remains in native vegetation, the Nebraska Wildlife Action Plan has identified the loss of …
Characterization Of Pyrethroid Resistance In The Western Corn Rootworm Diabrotica Virgifera Virgifera Leconte, Dariane Sagaseta De Oliveira Souza
Characterization Of Pyrethroid Resistance In The Western Corn Rootworm Diabrotica Virgifera Virgifera Leconte, Dariane Sagaseta De Oliveira Souza
Department of Entomology: Dissertations, Theses, and Student Research
The western corn rootworm (WCR), Diabrotica virgifera virgifera Le Conte (Coleoptera: Chrysomelidae), is a major pest of maize (Zea mays L.) in the United States and has continuously challenged our ability to develop sustainable pest management solutions. Resistance to chemical insecticides, crop rotation, and most recently transgenic plants that express toxins derived from Bacillus thuringiensis Berliner (Bt) have been well documented among WCR populations. Furthermore, US regulatory insecticide prohibitions and the lack of new active ingredients have reduced the options for WCR control. Pyrethroid insecticides are one of the few remaining chemical options. Therefore, the recent confirmation …
