Women In Beekeeping: Impacts Of A Beekeeper Educational Program, Bridget Gross
Women In Beekeeping: Impacts Of A Beekeeper Educational Program, Bridget Gross
Department of Entomology: Dissertations, Theses, and Student Research
The decline in honey bee populations over the past two decades in the United States is alarming. The management provided by beekeepers to their honey bee colonies influences the survival of the colony. However, there is a lack of information on the experiences of beekeepers, specifically women beekeepers. The Center for Rural Affairs (CFRA) in Nebraska hosted the “Honey Bees on the Farm: Connecting Women Beekeepers and Women Farmers for Environmental and Economic Benefit” program that provided informal, educational events to women beekeepers and landowners. Using a convergent mixed methods design, the first research question examines the impacts of the …

Evaluation Of Zerofly® Hermetic Storage Bags For Protection Of Maize Against Insect Pests In Ghana, Augustine Bosomtwe, Enoch Adjei Osekre, Georgina Bingham, George Opit
Department of Entomology: Faculty Publications
High post-harvest loss of maize due to stored product insect pests remains a food security challenge in Ghana. This field study evaluated the effectiveness of a novel technology, ZeroFly® Hermetic storage bags with different inner liners, to protect maize against infestation by Sitophilus zeamais Motschulsky and Prostephanus truncatus Horn. The study was carried out in the Department of Crop and Soil Sciences, Kwame Nkrumah University of Science and Technology, Ghana, during the period September 2017 to March 2018. Maize pre-fumigated with Phostoxin® was stored in 50-kg ZeroFly® Hermetic storage bags. Experimental treatments were 20-μm High Density Polyethylene (HDPE) inner liner …

Developing A Method To Contain The Feeding Of The Wheat Curl Mite (Aceria Tosichella Keifer), Pierce Leef, Gary Hein
Developing A Method To Contain The Feeding Of The Wheat Curl Mite (Aceria Tosichella Keifer), Pierce Leef, Gary Hein
UCARE Research Products
To better understand the ecology and epidemiology of the wheat curl mite (Aceria tosichella Keifer) as a vector of wheat streak mosaic virus (WSMV), it is necessary to develop a method to confine the microscopic mites and their infection to specific areas of their host plants, particularly wheat and corn. In this study, corn was the plant of interest. The device developed for this mite-confining method was made by removing the lens of a phone camera lens clip and gluing a 2.5 cm x 4.5 cm piece of wood to the other arm of the clip. Clips were utilized by …
Extreme Fire As A Management Tool To Combat Regime Shifts In The Range Of The Endangered American Burying Beetle, Alison K. Ludwig, Daniel R. Uden, Dirac Twidwell
Extreme Fire As A Management Tool To Combat Regime Shifts In The Range Of The Endangered American Burying Beetle, Alison K. Ludwig, Daniel R. Uden, Dirac Twidwell
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
This study is focused on the population of federally-endangered American burying beetles in south-central Nebraska. It is focused on changes in land cover over time and at several levels of spatial scale, and how management efforts are impacting both the beetle and a changing landscape. Our findings are applicable to a large portion of the Great Plains, which is undergoing the same shift from grassland to woodland, and to areas where the beetle is still found.

Sorghum Tolerance Of Phloem-Feeding Aphids, Earl Agpawa, Sajjan Grover, Joe Louis
Sorghum Tolerance Of Phloem-Feeding Aphids, Earl Agpawa, Sajjan Grover, Joe Louis
UCARE Research Products
Aphids are phloem sap-feeding insects that negatively affects plant productivity. With short generation times, new aphid biotypes may arise either in response to pesticide use or through other factors. Additional biotypes can cause serious damage to plants compared to others. Whereas others can become highly resistant to methods of pest control. One possible solution to this problem is to focus on the plant itself, or host plant resistance. Plant tolerance is one of the plant resistance categories in which the plant is capable of functioning normally and remain relatively unharmed and stable in response to insect herbivory without harming the …

Field Efficacy Of Soil Insecticides On Pyrethroid-Resistant Western Corn Rootworms (Diabrotica Virgifera Virgifera Leconte), Dariane Souza, Julie A. Peterson, Robert Wright, Lance Meinke
Field Efficacy Of Soil Insecticides On Pyrethroid-Resistant Western Corn Rootworms (Diabrotica Virgifera Virgifera Leconte), Dariane Souza, Julie A. Peterson, Robert Wright, Lance Meinke
Department of Entomology: Faculty Publications
Background: Field-evolved pyrethroid resistance has been confirmed in western corn rootworm (WCR) populations collected from the United States (US) western Corn Belt. Resistance levels of WCR adults estimated in lab bioassays were confirmed to significantly reduce the efficacy of foliar-applied bifenthrin. The objective of the present study was to investigate the impact of WCR pyrethroid resistance levels on the performance of common soil-applied insecticide formulations (23.4% tefluthrin, 17.15% bifenthrin, and 0.1% cyfluthrin+2.0% tebupirimphos). Field trials were conducted in 2016 and 2017 in three Nebraska, US, counties (Saunders, Clay, and Keith) where distinct levels of WCR susceptibility topyrethroids (susceptible, moderately resistant, …

Pereira, Premchand Gandra, Meghan L.F. Frey, Sarah Worden, Shannon Whitlock, Wendy Lo, Karl D. Schnelle, Jamie R, Lutz, Kenneth E. Narva, Blair Siegfried
Department of Entomology: Faculty Publications
Background: RNA interference (RNAi) triggered by maize plants expressing RNA hairpins against specific western corn rootworm ( WCR) transcripts have proven to be effective at controlling this pest. To provide robust crop protection, mRNA transcripts targeted by double-stranded RNA must be sensitive to knockdown and encode essential proteins.
Results: Using WCR adult feeding assays, we identified Sec23 as a highly lethal RNAi target. Sec23 encodes a coatomer protein, a component of the coat protein
(COPII) complex that mediates ER-Golgi transport. The lethality detected in WCR adults was also observed in early instar larvae, the life stage causing most …

Department of Entomology: Faculty Publications
Integrated crop–livestock systems (ICLSs) appear as a good alternative to increase nutrient use efficiency (NUE) in rice (Oryza sativa L.) through the improvement in nutrient cycling and soil chemical attributes in paddy fields. The objective of this study was to evaluate the impact of an ICLS on soil chemical attributes and on the fertilization requirement of N, P, and K by flooded rice in the Brazilian subtropical region. Nutritional status, yield, and NUE of flooded rice were evaluated by fertilization trials through rice response to different fertilization rates of N, P, and K. Soil chemical attributes were evaluated at …

West Central Research and Extension Center, North Platte
The western bean cutworm (WBC), Striacosta albicosta (Lepidoptera: Noctuidae), can be a severe pest of transgenic corn in the western Plains and Great Lakes regions of North America, including on hybrids expressing the Bacillus thuringiensis (Bt) Cry1F toxin. The level and geographic distribution of Cry1F resistance are not completely known. Neonate S. albicosta from 10 locations between Nebraska and New York state were subjected to dose–response trypsin-activated native Cry1F toxin overlay bioassays. In 2017, the mean estimated lethal concentration causing 50% larval mortality (LC50) ranged from 15.1 to 18.4 μg Cry1F cm−2, and were not significantly different among locations. In …
