Residues Of Thiamethoxam And Mefenoxam In Vegetative And Floral Tissue Of Soybean At The Early Reproductive Stage Resulting From Seed Treatments, Carolina Camargo, Daniel D. Snow, Sathaporn Onanong, Thomas Hunt, Blair Siegfried

Faculty Publications: Department of Entomology

Thiamethoxam with mefenoxam is the most widely used neonicotinoid insecticide/fungicide mixture applied to soybean (Glycine max [L]) as seed treatments. Based on the systemic nature of thiamethoxam and mefenoxam, residues of this insecticide/fungicide mixture may be present in soybean vegetative and floral tissue and negatively impact beneficial insects. Although neonicotinoids are often applied in combination with systemic fungicides, the research on ecological risks of neonicotinoids has been focused on the analysis of these compounds without considering their interaction with other agrochemicals. The objective of this study was to identify the concentration of thiamethoxam and mefenoxam in soybean flowers and …

A Gis Model For Apiary Site Selection Based On Proximity To Nectar Sources Utilized In Varietal Honey Production On Former Mine Sites In Appalachia, Douglass W. Potter

Theses and Dissertations--Forestry and Natural Resources

Beekeepers in Appalachia market varietal honeys derived from particular species of deciduous trees; however, finding places in a mountainous landscape to locate new beeyards is difficult. Site selection is hindered by the high up-front costs of negotiating access to remote areas with limited knowledge of the available forage. Remotely sensed data and species distribution modeling (SDM) of trees important to beekeepers could aid in locating apiary sites at the landscape scale. The objectives of this study are i) using publicly available forest inventory data, to model the spatial distribution of three native tree species that are important to honey producers …

Phylogeny And Population Genetic Analyses Reveals Cryptic Speciation In The Bombus Fervidus Species Complex (Hymenoptera: Apidae), Jonathan B. Koch, Juanita Rodriguez, James P. Pitts, James P. Strange

Ecology Center Publications

Bumble bees (Bombus Latrielle) are significant pollinators of flowering plants due to their large body size, abundant setae, and generalist foraging strategies. However, shared setal coloration patterns among closely and distantly related bumble bee species makes identification notoriously difficult. The advent of molecular genetic techniques has increased our understanding of bumble bee evolution and taxonomy, and enables effective conservation policy and management. Individuals belonging to the North American Bombus fervidus species-complex (SC) are homogenous in body structure but exhibit significant body color phenotype variation across their geographic distribution. Given the uncertainty of the genealogical boundaries within the SC, some …

Wild Bees Of Grand Staircase-Escalante National Monument: Richness, Abundance, And Spatio-Temporal Beta-Diversity, Olivia Messinger Carril, Terry Griswold, James Haefner, Joseph S. Wilson

All PIRU Publications

Interest in bees has grown dramatically in recent years in light of several studies that have reported widespread declines in bees and other pollinators. Investigating declines in wild bees can be difficult, however, due to the lack of faunal surveys that provide baseline data of bee richness and diversity. Protected lands such as national monuments and national parks can provide unique opportunities to learn about and monitor bee populations dynamics in a natural setting because the opportunity for large-scale changes to the landscape are reduced compared to unprotected lands. Here we report on a 4-year study of bees in Grand …

South American Leaf-Cutter Bees (Genus Megachile) Of The Subgenera Rhyssomegachile And Zonomegachile, With Two New Subgenera (Hymenoptera: Megachilidae), Víctor H. González, Terry Griswold, Michael S. Engel

All PIRU Publications

Leaf-cutter bees (genus Megachile Latreille) are among the most common and diverse group of bees. However, the identity and taxonomic placement of many species are problematic and species identification is often difficult. Some species are known only from a single specimen or from one of the sexes, and identification keys are not available for many groups. We address these taxonomic issues for the subgenera Rhyssomegachile Mitchell and Zonomegachile Mitchell, two poorly known South American lineages of leaf-cutter bees. We provide comparative diagnoses, redescriptions, illustrated identification keys, new geographical records, and designate needed neotypes for Megachile cara Mitchell, M. gigas Schrottky, …

Honey Bee And Bumble Bee Antiviral Defense, Alexander J. Mcmenamin, Daughenbaugh F. Katie, Fenali Parek, Marie C. Pizzorno, Michelle L. Flenniken

Faculty Journal Articles

Bees are important plant pollinators in both natural and agricultural ecosystems. Managed and wild bees have experienced high average annual colony losses, population declines, and local extinctions in many geographic regions. Multiple factors, including virus infections, impact bee health and longevity. The majority of bee-infecting viruses are positive-sense single-stranded RNA viruses. Bee-infecting viruses often cause asymptomatic infections but may also cause paralysis, deformity or death. The severity of infection is governed by bee host immune responses and influenced by additional biotic and abiotic factors. Herein, we highlight studies that have contributed to the current understanding of antiviral defense in bees, …

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender

Student Theses 2015-Present

This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim …

Miscellaneous Reports

Bees are crucial to pollination in unmanaged ecosystems and some crops, and their roles are increasingly understood in four states in the Northeastern U.S., abbreviated “NNE” in this paper: Maine (ME), Massachusetts (MA), New Hampshire (NH), and Vermont (VT). The four states have in common many native bee and plant species, forest types, and natural communities. They share drought events and risk of wildfire (Irland 2013). They are exposed to many of the same major storms (e.g., hurricanes, Foster 1988), pollution events (Hand et al. 2014), and effects ascribed to climate change (Hayhoe et al. 2008). Beekeeping enterprises (the western …

T Socio-Ecology Of Managed Honeybees (Apis Mellifera) In The Louisville Metro Area., Haileigh M. Arnold

Electronic Theses and Dissertations

Humans have a long history of the practice of beekeeping to harness the power of pollination. This managed pollinator system consists of beekeepers, honeybees, and their environment. However, recent disease, pesticide use, and land use factors honeybee threaten this relationship. In the face of such concerns it is important to examine the factors that impact and can help sustain our managed pollinator systems. In this thesis, the national and Kentucky state-level policies that affect managed pollinator systems were examined and socio-ecological factors that may contribute to honeybee hive growth and losses were assessed along an urban development gradient in Louisville, …

The Effect Of Three Different Mulches On Weed Presence, Soil Characteristics, And Zinnia Growth, Anmar Muttaleb

Murray State Theses and Dissertations

Abstract

Organic and inorganic mulching helps to control weeds. Mulching helps cultivated plants to grow by inhibiting the growth of weeds, retaining soil moisture, and regulating the temperature of soil. The objective of this study was to determine the effects of different organic mulches on weed presence, soil characteristics, and growth of Zinnia elegans. The mulches used in studying Zinnia elegans were wheat straw, non-shredded Miscanthus (M. × giganteus), and shredded Miscanthus (M. × giganteus) mulch. A Randomized Complete Block Design (RCBD) was used in the study, with different quantitative methods were used to …

All Roads Lead To Weediness: Stories About Weedy Rice Origins, Weedy Genes And Weed Competitiveness, Zhongyun Huang

Doctoral Dissertations

Weedy rice (Oryza spp.), a weedy relative of cultivated rice (O.sativa), infests and persists in cultivated rice fields worldwide. Many weedy rice populations have evolved similar adaptive traits, considered part of the ‘agricultural weed syndrome’, making this an ideal model to study the genetic basis of parallel evolution. Using population genetics analyses of South Asian and US weedy rice, my research reveals multiple independent evolution events giving rise to weed groups in the two geographic areas. Weeds in South Asia have highly heterogenous genetic backgrounds, with contributions from both cultivated varieties (aus and indica) …

Gatekeepers Of Nitrogen-Fixing Symbiosis: Cytokinin-Ethylene Crosstalk Regulates Symbiotic Interaction In Lotus Japonicus, Seyedehmandana Miri

Electronic Thesis and Dissertation Repository

Leguminous plants thrive under nitrogen-limited soil conditions because of their ability to symbiotically interact with nitrogen-fixing bacteria, known as rhizobia. In the presence of compatible strains of rhizobia, they develop specialized symbiotic organs, called root nodules, which host the bacteria and provide the appropriate conditions for symbiotic nitrogen fixation to occur. The plant hormone cytokinin is the key endogenous trigger for the inception of root nodule organogenesis. In the model legume Lotus japonicus, analysis of the cytokinin receptor gene Lotus histidine kinase 1 (Lhk1) showed that it is required and also sufficient for the initiation of nodule …

A Performance Study Of Apis Mellifera With Dietary And Forage Restrictions During Spring Colony Establishment In Lyon County, Kentucky, Dominique Wood

Murray State Theses and Dissertations

One-third of our worldwide fruit, nut and vegetable production is completely dependent on the existence of pollinators. Commercial honey bees, Apis mellifera, have an annual economic value of $15 billion in the U.S. Additionally, their honey is valued at $150 million annually. In Fall 2006, commercial beekeepers observed sudden mass disappearances of whole colonies. By Spring 2007, the condition, dubbed Colony Collapse Disorder (CCD), raised environmental and fiscal concerns while the cause(s) continued to be sought. Forensic examinations of hive samples did not reveal a singular cause of CCD. The results pointed to a collection of detrimental factors affecting …

Why We Still Need To Worry About Bees, Meaghan Lee Callaghan

Capstones

American honey bees, and other native bee species, are still in decline, though the specter of colony collapse disorder may be fading behind us. Colony decline, the loss of bees overwinter experienced across the country at a quarter to third lost per hive (sometimes more), is now expected. Losses can include those from colony collapse disorder. The author discusses the different causes for colony decline and speaks to bee health scientists and local beekeepers.

Soil-Water Transport Of A Seed Coated Neonicotinoid Pesticide In Soybean/Maize Cultivation Systems, Geoffrey Nathaniel Duesterbeck

Masters Theses

The current decline of the honey bee (Apis mellifera L.) and other beneficial pollinator species is well documented. Several causes have been cited in this decline including: pathogens, pests, nutrition, and pesticide exposure. Since the advent of the neonicotinoid family of pesticides in the 1990’s an increase in honey bee colony loss has been observed. Neonicotinoid pesticides are commonly applied as a seed treatment to cotton, soybean and maize row crops. As the seed germinates, it absorbs the pesticide from the coating then spreads systemically throughout the entire plant. However, a large portion of the seed coating may stay …
