Entomology Outreach Presentations To Four Audiences, Michael Goldman Jan 2023

Entomology Outreach Presentations To Four Audiences, Michael Goldman

Department of Entomology: Distance Master of Science Projects

I proposed that my master’s Project would be outreach on Entomology at four levels: School aged children, laymen, non-entomologists in a technical field, and entomologists. The idea here is basically how to talk about entomology to varying levels of expertise, from first graders to experts in both entomology and occupational health and safety. Presentations were given to audiences at each of the four levels. The specific topics varied for each audience. The determination was made by the inviting audience in the cases of school aged children and adult laymen and by me in the cases of Occupational Safety and Health …


Entomophagy: Mealworm Protein In An Inpatient Hospital Setting (Engagement And Education To Rollout Entomophagy For Improved Nutrition), Caryl Showalter Jan 2023

Entomophagy: Mealworm Protein In An Inpatient Hospital Setting (Engagement And Education To Rollout Entomophagy For Improved Nutrition), Caryl Showalter

Department of Entomology: Distance Master of Science Projects

The consumption of insects (entomophagy) is a well-practiced phenomenon in many parts of the world. Western societies, including the US, are among the few places that do not participate in this practice. However, entomophagy has the potential to ease nutritional burdens, globally. While many may believe that nutritional deficits are a relic of more economically challenging times or a problem specifically linked to the low economic countries, the truth is that any area can face this problem. This was made clear in the US during the coronavirus lockdown with an estimated doubling in food insecurity associated with a lack of …

Temporal, Phenotypic, And Quantitative Characterization Of Thyroid Infiltrating Mononuclear Cells During Development Of Spontaneous Autoimmune Thyroiditis In Obese Strain Chickens, Katelyn M. Clark, Chrysta N. Beck, Gisela F. Erf Jan 2023

Temporal, Phenotypic, And Quantitative Characterization Of Thyroid Infiltrating Mononuclear Cells During Development Of Spontaneous Autoimmune Thyroiditis In Obese Strain Chickens, Katelyn M. Clark, Chrysta N. Beck, Gisela F. Erf

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

The Obese strain (OS) of chickens spontaneously develops autoimmune thyroiditis (SAT) and is a well-established biomedical model for Hashimoto’s thyroiditis in humans. Both conditions are characterized by the infiltration of thyroid glands with mononuclear immune cells resulting in the destruction of thyroid tissue and impairment of the thyroid’s endocrinological functions. Past studies described immune cell infiltration in thyroids of the OS chickens, but the time-course, cell composition, and relative amounts of the various immune cells infiltrating the thyroids have not been well defined. In this project, frozen and stored thyroid glands that were previously collected at 1, 4, 7, 14, …


Validation Of A Diagnostic Marker For Primocane-Fruiting In Blackberry, Isabella Vaughn, Alexander Silva, Carmen Johns, Lacy Nelson, Margaret Worthington Jan 2023

Validation Of A Diagnostic Marker For Primocane-Fruiting In Blackberry, Isabella Vaughn, Alexander Silva, Carmen Johns, Lacy Nelson, Margaret Worthington

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

Typical blackberries (Rubus subgenus Rubus) have perennial crowns and roots and biennial canes. The first-year canes (primocanes) are usually vegetative, while second-year canes (floricanes) produce fruit. Primocane-fruiting blackberries produce fruit on first-year canes and are desirable to growers because they potentially allow for a longer harvest season in temperate regions and enable production in tropical areas where no natural chill hours are accumulated. The development of molecular markers for desirable traits can potentially increase efficiency in blackberry breeding. However, to date, there are no diagnostic molecular markers for economically important traits in blackberries. Primocane-fruiting is recessively inherited, and tetraploid blackberries …

The purpose of this project was to help children reach more developmental goals and to make outdoor play at the Jean Tyson Child Development Study Center more inclusive for all children. Children gain many developmental goals from playing outside and being exposed to other environments as compared to just being inside the classroom. Outdoor play should be as inclusive as indoor play and offer many different activities and outlets, just as the indoor classroom does. The implementation of this service-learning creative project was to add more versatility to the outdoor area at the University of Arkansas Jean Tyson Child Development …


Intestinal Parasite Infection In Tibetan Macaques (Macac Thebetana) In Eastern China, Miarisoa Ramilison Jan 2023

Intestinal Parasite Infection In Tibetan Macaques (Macac Thebetana) In Eastern China, Miarisoa Ramilison

All Master's Theses

Grooming is one of the crucial social behaviors of primate species that functions to remove parasites and maintain social bonds. Although, much data exists to support the idea that grooming is essential in forming and sustaining social bonds among individuals, there is a lack of information about the extent to which it removes ectoparasites or contributes to the spread of internal parasites. To fill this gap in the literature, we investigated the relationship between social contact behavior including grooming and intestinal parasite infection in Tibetan macaques (Macaca thibetana). This species lives at Mt. Huangshan in China. We used …

Teaching Forensic Entomology With Common Grocery Items: Decomposition And Insect Succession Studies, Erin Bauer, Charles Murrieta, Larry Barksdale

Department of Entomology: Faculty Publications

Forensic science and entomology programs may benefit from using deceased pigs as teaching resources due to anatomical similarities to humans. The use of such animals provides opportunities for students to learn the effects of geographical location and climate on insects; understand insect succession; practice insect collection and identification; and learn post-mortem interval procedures, taphonomic principles of decomposition, and crime scene investigation and management techniques. Forensic entomology and taphonomic studies fit well with educational interests in experiential learning. Pigs may be readily available through animal science departments or local producers, and many institutions may have property where this research can be …

Effects Of Cyclic Heat Stress On The Acute Inflammatory Response In Broilers, Alessandro J. Rocchi, Chrysta N. Beck, Jossie M. Santamaria, Gisela F. Erf

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

Heat stress (HS) is a growing concern in broiler production. Little is known regarding the effect of HS on immune function. To examine the effects of HS on innate immunity, the local- and systemic-inflammatory responses to lipopolysaccharide (LPS) were examined in Cobb 500 male broiler chicks reared under thermoneutral (TN) or cyclic HS conditions. Beginning at four days of age, HS birds were subjected to 35 °C from 8:00 a.m. to 10:00 p.m. and TN temperatures from 10:00 p.m. to 8:00 a.m. At 37 days of age, four groups of broilers were formed: LPS-TN (8 broilers), phosphate-buffered saline (PBS)-TN (4 …

Wastewater-recovered phosphorus (P), in the form of the mineral struvite (MgNH4PO4∙6H2O), may provide a sustainable alternative to decreasing rock-phosphate reserves. Struvite can be generated via precipitation methods, potentially reducing the amount of P runoff to aquatic ecosystems. The objective of this greenhouse tub study was to evaluate the effects of chemically and electrochemically precipitated struvite (CPST and ECST, respectively) on aboveground plant response in a hybrid rice cultivar grown using furrow-irrigation compared to other common fertilizer-P sources [i.e., triple super phosphate (TSP) and diammonium phosphate (DAP)] using three replications of fertilizer treatment in a P-deficient silt loam (Typic Glossaqualfs). Aboveground …

In Ethiopia, malaria incidence has significantly reduced in the past decade through the combined use of conventional vector control approaches and treatment using antimalarial drugs. However, the sustainability of this achievement is threatened by the shift in biting and resting behaviors and emergence of insecticide resistance by the primary malaria vector. Therefore, continuous monitoring of the behaviour of malaria mosquitoes in different sentinel sites is crucial to design effective prevention and control methods in the local context. Entomological investigations were conducted in three sentinel sites for five consecutive months during the major malaria transmission season. The species composition, population dynamics, …

Aedes aegypti (L.), the yellow fever mosquito, is also an important vector of dengue and Zika viruses, and an invasive species in North America. Aedes aegypti inhabits tropical and sub-tropical areas of the world and in North America is primarily distributed throughout the southern United States states and Mexico. The northern range of Ae. aegypti is limited by cold winter months and establishment in these areas has been mostly unsuccessful. However, frequent introductions of Ae. aegypti to temperate, non-endemic areas during the warmer months can lead to seasonal activity and disease outbreaks. Two Ae. aegypti incursions were …


Effect Of Larval Rearing Environment On Female Bicyclus Anynana Mate Choice, Adriana Beruvides May 2022

Effect Of Larval Rearing Environment On Female Bicyclus Anynana Mate Choice, Adriana Beruvides

Biological Sciences Undergraduate Honors Theses

Around eighty percent of animals go through metamorphosis or drastic phase changes at some point in their life. We know that juvenile interactions can influence adult behavior and mate choice in species that don’t go through metamorphosis, but we know very little about how social interactions during early life stages of animals who go through metamorphosis affect mate choice. To fill this knowledge gap, I used the butterfly Bicyclus anynana to assess whether female butterflies raised in complete isolation from the beginning of their lives exhibit the same mate preference as butterflies raised in normal social conditions. To test this, …


Using Community Science To Assess The Effect Of Wing Pattern And Weather On Butterfly Behavior, Abbigail Merrill May 2022

Using Community Science To Assess The Effect Of Wing Pattern And Weather On Butterfly Behavior, Abbigail Merrill

Animal Science Undergraduate Honors Theses

Signaling in insects is used as communication and for attraction of mates. The physical appearance of the insect as well as conditions such as weather can play a role in visual signaling, by influencing the wavelengths of light available, and subsequent signal detection. We do not know, however, whether signals butterflies present broadly correlate with how they behave. In this study, we looked at the wing patterns and behavior of butterflies in Northwest Arkansas over a 3.5-year period to assess the relationship between wing pattern, weather, and behavior. We used observational data collected by hundreds of University of Arkansas students …


Using Ai To Examine Nocturnal Moth Pollination, Conor Moriarty May 2022

Using Ai To Examine Nocturnal Moth Pollination, Conor Moriarty

Biological Sciences Undergraduate Honors Theses

The importance of insect-mediated agriculture cannot be understated especially in the wake of pollinator population declines. Most research of insect-mediated pollination is focused on diurnal pollinators like the honeybee (Apis mellifera). Deepening our understanding of how other pollinators, such as nocturnal pollinators, can benefit agriculture and ecosystems will be very important as honeybee populations decline. I explored nocturnal moth interactions with flowering apple flowers during their pollination season to better understand how these nocturnal pollinators interact with the plants. To accomplish this, I used a University of Arkansas farm area with a dedicated apple orchard. I gathered my raw data …


Effect Of Larval Experience On Learning Mate Preference In Bicyclus Anynana, Taryn Tibbs May 2022

Effect Of Larval Experience On Learning Mate Preference In Bicyclus Anynana, Taryn Tibbs

Biological Sciences Undergraduate Honors Theses

Phenotypic traits are shaped by the interaction of an organism's genes and the environment they experience. The plasticity of phenotypic traits is particularly responsive to developmental environments which can shape adult traits, such as expressed behaviors like mate choice and the ability to learn preferences. The Lepidoptera species Bicyclus anynana has been shown to learn mate preference based on social interaction following emergence from the chrysalis, however if and how the social complexity of the larval experience affects this ability to learn is less understood. Here I test the effects of isolation during the larval period on a female’s ability …

Preventative Weed Management Strategies In Arkansas Tomato Production, Gracie E. Morrison, Matthew Bertucci

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

Cost-effective weed suppression is an important consideration for tomato growers. Growers often choose methods which minimize hand labor, as hand weeding can be prohibitively expensive. This project determined economic viability of high tunnel tomatoes treated with several methods of weed control, both organic and chemical. These methods included: 2-week hand weeding, 1-week hand weeding, preemergent herbicide application (plots sprayed with herbicide prior to weed emergence), straw mulch (plots bedded with straw), landscape fabric (plots covered in fabric), and untreated weedy control plots. These six treatments were applied to randomized blocks in a high tunnel. Weeding, planting, and harvesting were all …
