Establishment Of Pollinator Habitat Within A Livestock Pasture Ecosystem, Roshani Sharma Acharya

Graduate Theses and Dissertations

Pollinators are important for fertilization, setting fruits, and seed development of more than 78% of the flowering plants that provide food for human beings and other species. Use of pollinators to maximize crop production is a proven agricultural practice; however, it has been less explored in livestock forage production systems. This study investigated pollinator abundance and diversity in pastures using different sampling methods and determined the impact of different pasture management practices on insect pollinators in a livestock pasture ecosystem. In Chapter 2, utility of four different colors of pan trap (blue, green, yellow, and purple) for sampling bees in …

Cover Crops As An Integrated Approach For Pest Suppression And Pollinator Promotion In Arkansas Watermelon Production Systems, Paige Laurel Hickman

Graduate Theses and Dissertations

Arkansas watermelon growers face a variety of insect pest and disease problems that have the potential to threaten yield. Integrated pest management tactics can provide control over these threats and are intended to cut down on pesticide use and its associated negative impacts like pesticide resistance, non-target effects, and runoff. Cover crops provide an array of benefits and can be useful in integrated pest management. Evidence has shown that certain cover crops can increase beneficial insects and suppress disease in the following cash crop. They can also provide important resources to pollinators. In order to build a better understanding of …

Flowering Resources Distract Pollinators From Crops: Model Predictions From Landscape Simulations, Charlie C. Nicholson, Taylor H. Ricketts, Insu Koh, Henrik G. Smith, Eric V. Lonsdorf, Ola Olsson

Rubenstein School of Environment and Natural Resources Faculty Publications

Enhancing floral resources is a widely accepted strategy for supporting wild bees and promoting crop pollination. Planning effective enhancements can be informed with pollination service models, but these models should capture the behavioural and spatial dynamics of service-providing organisms. Model predictions, and hence management recommendations, are likely to be sensitive to these dynamics. We used two established models of pollinator foraging to investigate whether habitat enhancement improves crop visitation; whether this effect is influenced by pollinator foraging distance and landscape pattern; and whether behavioural detail improves model predictions. The more detailed central place foraging model better predicted variation in bee …

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 …

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, …

The Future Of Food In Blade Runner 2049, Diarmuid Cawley

Other resources

The science fiction genre has always been a hotbed for questions about the existence of life and what it means to be human. Food, like water and oxygen, is necessary to sustain life, but also is a key indicator of culture. One of the things that fascinates us about science fiction is how an imagined future culture might look. Blade Runner 2049, although not centred around food, interweaves food and agriculture into a dystopian narrative on evolution and a bio-engineered labour force, while asking us what it means to have memories and to be human.

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.

Population Genetics, Distributions And Phenology Of Bombus Latreille, 1802 And Xylocopa Latreille, 1802 (Hymenoptera: Apidae), Amber Dawn Tripodi

Graduate Theses and Dissertations

This work addresses multiple knowledge gaps in bee ecology, population health and phylogeography in order to provide insights into the changing distributions of native bees. A comparison of Arkansas bumble bee records mirrors range-wide surveys, with records of stable species (Bombus bimaculatus Cresson, 1863 and B. impatiens Cresson, 1863) increasing three-fold, and records of the declining B. pensylvanicus (DeGeer, 1773) dropping to 60% of historical levels. However, nationally-recommended conservation-genetics tools did not mirror these results on a regional level. Stable and declining species had equivalent genetic diversity in samples from Arkansas and Tennessee (H_S range: 0.46-0.63). Diploid males, …

An Economic Analysis Of Wild Bee Pollination In Lowbush Blueberry Production, Francis A. Drummond

University of Maine Office of Research Administration: Grant Reports

The purpose of this project is to determine the relative economic values of wild bee pollinators and commercial honeybees in lowbush blueberry production for individual Maine farms. The lowbush blueberry requires insect pollination in order to set fruit. Most farmers rent colonies of the non-native honeybee for pollination services, but wild, native bees are also effective pollinators. This project aims to provide growers with the means to assess the pollination needs of individual fields and to understand the levels of pollination possible if honeybees are not available. In order to achieve these goals, the relative abundance and species diversity of …

Mapping The Margin: Comparing Marginal Values Of Tropical Forest Remnants For Pollination Services, Taylor H. Ricketts, Eric Lonsdorf

Rubenstein School of Environment and Natural Resources Faculty Publications

Natural ecosystems benefit human communities by providing ecosystem services such as water purification and crop pollination. Mapping ecosystem service values has become popular, but most are static snapshots of average value. Estimating instead the economic impacts of specific ecosystem changes can better inform typical resource decisions. Here we develop an approach to mapping marginal values, those resulting from the next unit of ecosystem change, across landscapes. We demonstrate the approach with a recent model of crop pollination services in Costa Rica, simulating deforestation events to predict resulting marginal changes in pollination services to coffee farms. We find that marginal losses …

The Buzz On Bees, Rebecca Ruiz

Lewis Honors College Capstone Collection

Apis mellifera, more commonly known as the honeybee, plays a pivotal role in the ecosystem and in the survival of the planet. Many do not understand, nor realize, that the honeybee offers a wide array of products and services besides sweet honey. Honeybees have become endangered at a time when their presence is vital and evidence indicates that they can be the means to a more sustainable future for our planet. Particularly focused on in this research are the ideas of honeybees’ essential presence in medical advances, their participation in global economics, and their involvement in the development of …

Bee Visitation To Crops And Other Flowers Planted As Bee Food, Michael Edward Wilson

Masters Theses

Farms that require insect pollination and reside in diverse landscapes benefit from pollination by native bees. However, populations of native bees and honey bees are generally in decline and this threatens food production. Documentation of crop pollination as an ecosystem service is needed to identify potential impacts from declining bee populations. This study identifies communities of bees providing pollination and how they vary across different crops and environmental conditions. Managing landscapes to provide additional food sources for bees may improve the health of wild and managed bees. This study also evaluated the attractiveness of bees to selected species of plants …

G01-1430 Using The Sugar Roll Technique To Detect Varroa Mites In Honey Bee Colonies, Marion D. Ellis, Paul A. Macedo

University of Nebraska-Lincoln Extension: Historical Materials

This NebGuide describes a rapid and efficient technique for detecting and assessing varroa mite infestations. It uses powdered sugar to dislodge mites from bees.

The varroa mite was first discovered in the United States in 1987. Globally, it is the most important pest of honey bees and it has caused extensive losses in feral and managed colonies. Once introduced, varroa mites have never been eradicated from any country or region, and beekeepers must adopt an integrated pest management strategy to protect their colonies. Early detection and assessment of infestation levels are important components of a varroa management plan. Since varroa …

Beekeeping in Nebraska

There are approximately 700 beekeepers in Nebraska operating about 115,000 colonies of bees. Annual honey production in the state ranges from 5 to 11 million pounds depending on weather conditions and available flora. The honey from each area is a unique blend of nectars from the available flora. In a good area under favorable conditions, a properly managed colony can produce 100 pounds or more of honey. The six-year average (1986-1991) for honey production per colony in Nebraska is 75 pounds.

Of far greater importance is the role …

Disease Of Bees, R S. Coleman

Journal of the Department of Agriculture, Western Australia, Series 3

All beekeepers dread the appearance of disease in their hives, for it means at the least a large drop in the honey crop and at the worst, complete destruction of whole apiaries and the beekeepers' means of livelihood. Quite apart from the economic loss, beekeepers are usually men who work with bees because they like them, and naturally they do not want to see whole colonies destroyed.

Efficiency In The Apiary, R S. Coleman

Journal of the Department of Agriculture, Western Australia, Series 3

Efficiency is a word that most people associate with factories and city life, but it is just as important, if not more important, for the primary producer. Reduced to everyday English, efficiency means more goods produced with less labour and with lower capital investment for the unit of produce sold. Efficiency can be called planned business commonsense designed to save time and money.
