Instrumental Insemination Of Honey Bees Short Course, Cory Stevens

Department of Entomology: Distance Master of Science Projects

My MS project is a practical and comprehensive training module for the advanced breeding technique of instrumental insemination of honey bee queens. Instrumental insemination allows for control over mating. Honey bee queens typically mate with 15-20 different drones in the air, making specific trait selection quite difficult. II is invaluable for concentrating specific traits in breeding stock, especially host pest resistance. The commercial bee industry has become overly reliant on chemical solutions to control varroa mites in their IPM programs. With recent evidence of mite resistance to popular miticides, breeding for host resistance is critically important to sustain the industry. …

Effects Of Drought On Habitat Quality For Native Bees In Residential Gardens Of Claremont, Ca, Max Proctor

CMC Senior Theses

Over 1,500 of the 4000 bee species found in North America inhabit California. Native bees are declining however, largely due to climate change and agricultural intensification. Previous research shows that cities can sustain diverse bee communities, due to the diversity of ornamental flowers. Urban green space represents an opportunity for native bee conservation. Residential gardens provide lots of green space and are urban pollinator hotspots. Managing yards for increased floral resources and nesting habitat can benefit native bee communities. Turfgrass provides few floral or nesting resources and negatively correlates with bee diversity. The 2011-2017 California drought caused many homeowners to …

Mortality In Interspecific Hybrids Of Nasonia Vitripennis And Nasonia Giraulti, Bonnie Cobb

Electronic Theses and Dissertations

Nasonia is a parasitoid wasp genus that serves as an emerging model for studying speciation due to an incompatibility between nuclear and mitochondrial genomes between sister taxa. Short generation times, easy rearing in a lab setting, producing large amounts of progeny, and whole genome sequencing make Nasonia is an excellent candidate for studying incomplete reproductive isolation. Nasonia have five chromosomes and exhibit haplo-diploid sex determination in which fertilized eggs develop into diploid females and unfertilized eggs develop into haploid males. Recessive phenotypes are hidden in diploid females but are laid bare in haploid males as there is no interaction between …

Using Poultry To Enhance Food Security In Stann Creek, Belize, Emily Spatz, Lisa S. Wood

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Food insecurity is a growing issue in developing and developed countries alike, and in countries like Belize, the prevalence of hunger has soared in recent years. Not having access to diets with sufficient calories and nutrients leads to a host of developmental issues, including stunting and cognitive delays. The purpose of this work was to create an all-encompassing manual for small-scale poultry production in order to provide nourishment for the students and staff of a school in Belize. After determining that the best way to meet the school’s needs was through dual-purpose birds, background research was conducted to determine small-scale …

Variation In Oviposition Behaviour Of Blow Flies (Diptera: Calliphoridae) Due To Relative Humidity And Intraspecific Interactions, Theresa Tran

Electronic Theses and Dissertations

Blow flies are usually the first insects to arrive at carrion, using it to oviposit or breed. The behaviour to search for and accept a carrion resource as suitable for oviposition is influenced by abiotic factors, particularly temperature and humidity, as well as by the presence of other insects. My thesis focuses on the influence of relative humidity (RH), combined with intraspecific interactions, on oviposition choices of three blow fly species Lucilia sericata (Meigen), Phormia regina (Meigen), and Calliphora vicina Robineau-Desvoidy (Diptera: Calliphoridae). Individual fly oviposition behaviour was measured on a temperature gradient (10-40°C) under high (75- 85%) and low …

Artificial Intelligence System For Automatic Imaging, Quantification, And Identification Of Arthropods In Leaf Litter And Pitfall Samples, Pierce Helton, Khoa Luu, Ashley Dowling

Inquiry: The University of Arkansas Undergraduate Research Journal

It is well known that arthropods are the most diverse and abundant eukaryotic organisms on the planet. Museum and research collections have huge insect accumulations from expeditions conducted over history that contain specimens of both temporal and spatial value, including hundreds of thousands of species. This biodiversity data is inaccessible to the research community, resulting in a vast amount of “dark data”. The primary objective of this study is to develop an artificial intelligence-driven system for specimen identification that greatly minimizes the time and expertise required to identify specimens in atypical environments. Successful development will have profound impacts on both …

Preliminary Survey Of Insect Communities On Carrion In The Keweenaw Peninsula, Mi In Early Summer, With A Focus On Dipterans, Tess A. Peterson

Department of Entomology: Distance Master of Science Projects

Community composition and successional information about insect communities on carrion have value in forensic entomology. Local scale data is essential for providing accurate inferences about the timing and conditions of a death based on insect presence. Insects (primarily Diptera) were collected from beef liver in the month of June, 2021, at mixed hardwood and wetland sites in Houghton County, Michigan for the purpose of establishing preliminary information on insect communities present on carrion in the Western Upper Peninsula of Michigan. Key dipteran groups were Calliphorids from the genera Calliphora, Lucilia, and Phormia (Diptera: Calliphoridae), which were present at high proportions …

An Overview Of Integrated Pest Management In Greenhouse Systems, Kateri Cavanagh

Department of Entomology: Distance Master of Science Projects

Greenhouses are technological advancements that have existed since the first century. Human life and the field of agriculture have greatly improved with their invention. However, greenhouses come with their own set of challenges. One of the biggest issues with greenhouse systems is the presence of large pest populations. This is due to the ample food and water supply along with the relative stability of greenhouses. Pests in greenhouses are usually dealt with through the application of chemical pesticides. However, integrated pest management (IPM) is gaining traction for use in greenhouse systems. This overview will cover the history of greenhouses and …

Why urban and suburban areas? Insects are critical not only to natural and agricultural ecosystems. but also to urban ecosystems. Urban environments are characterized by a patchwork of habitat "islands" including home gardens, university campuses, urban parks and farms, vacant lots, cemeteries, arboreta, and botanicaL gardens [1). These habitat islands are the focus …

Counting Butterflies In Yosemite: A Guide For Beginners, Christine Melvin

Department of Entomology: Distance Master of Science Projects

Entomology is the study of insects. Insects are the most numerous animal group on the planet and therefore the field of entomology is further divided based upon insect groups. Butterflies and Moths belong to the insect group Lepidoptera. An entomologist who studies butterflies and/or moths is called a Lepidopterist. Butterflies are a special group of insects because they are not only studied by entomologists, but they are also studied by people called citizen scientists. Citizen science is the casual participation in gathering of data about anything relating to science. Anyone who uses the app iNaturalist is a citizen scientist because …

A Review Of The Repellency Properties Of Pyrethrins, Gary Frazier

Department of Entomology: Distance Master of Science Projects

Pyrethrum is an insecticide created from the dried flower heads of plants in the genus Chrysanthemum. The six compounds responsible for the insecticidal activity are collectively known as pyrethrins, and are known individually as Pyrethrin-I, Pyrethrin-II, Cinerin-I, Cinerin-II, Jasmolin-I, and Jasmolin-II. Of these compounds, Pyrethrin-I is best known for mortality, and Pyrethrin-II is best known for knockdown activity (Sisay et al. 2001). These compounds are voltage gated sodium-ion channel disruptors acting on nerve cells. The inside of nerve cells is negative relative to the outside at rest. It is due to an imbalance between ions on either side of the …
