Japanese Beetle (Popillia Japonica), Asmita Gautam, Karla M. Addesso, Anju Poudel, Jason B. Oliver

Extension Publications

Japanese beetle (Coleoptera: Scarabaeidae), Popillia japonica Newman, is an invasive beetle introduced from Asia to the United States in the early 1900s. It was first detected in New Jersey and later distributed in 28 states in the United States (Fig 1). In Tennessee, the beetle population was first detected in 1936, and about 80 counties in Tennessee have been infested by their establishment. Adult beetles feed on over 300 plant species, including foliage, fruits, and flowers. It is a significant pest of turfgrass, and ornamental and horticultural crops in the eastern United States. Adults and larvae aggregate on the plants …

Data For "Linking Previous Experiences To Behavior And Health In The Honey Bee (Apis Mellifera)"", Rebecca R. Westwick, Clare C. Rittschof, Gavin P. Brackett, Cameron E. Brown, Bethany J. Ison, Zainulabbeudin Syed, Anna M. Foose

Entomology Research Data

An organism’s ability to respond to changing conditions can be vital to its success. Indeed, plasticity is a common feature of living organisms. Much of the research in this area, though, has focused on effects caused by environmental conditions. What has received relatively less attention is how social experiences and broader features of an organism’s social environment can lead to long-lasting changes in health and behavior. This knowledge gap exists despite the well-documented existence of health and behavioral effects after social interactions in certain taxa such as humans.

Social insects such as honey bees provide an excellent opportunity to better …

Fostering Infant And Toddler Music Competence At The Jean Tyson Child Development Study Center, Ellen Mathews, Laura Herold, Shelley Mcnally, Donia Timby

This paper presents a creative research project that introduced musical instruments in an outdoor setting to infants and toddlers ages 0-to-3 years old. It was grounded in research suggesting that music plays a vital component in expanding development in the early childhood years, helping to promote learning across many domains. This project began with a survey distributed to 7 infant and toddler classroom educators, after which responses were analyzed for themes regarding perceived infant interests. Subsequent observations were conducted to evaluate the best fit for the implementation of an outdoor experiential music space. Based on the findings, a developmentally appropriate …

Effects Of Time-Restricted Feeding And Whey Protein Isolate Supplementation On Dietary Intake, Mood, And Sleep In A 12-Week Randomized Controlled Trial, Sydney E. Boudrey, Aubree L. Hawley

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

Obesity affects adults in the United States, leading to chronic diseases and reduced well-being. Time-Restricted Feeding (TRF) is a type of dietary intervention lacking current data regarding the effectiveness on facets of well-being. This study’s objective was to determine the effect of time-restricted feeding supplemented with whey protein isolate on food intake, sleep, and mood in overweight or obese adults. Nineteen participants were randomly assigned to the control or experimental group: 1) control, TRF, and 2) experimental, TRF with whey protein supplementation. Participants followed the assigned dietary intervention for 12 weeks. Every 4 weeks (baseline, week 4, week 8, and …

Palatability, Consumption, And Physiological Effects Of The Green Microalgae Chlorella Sp. As A Feed Substitute For The Western Honey Bee Apis Mellifera In A Laboratory Setting, Benjamin J. Nichols

Department of Entomology: Distance Master of Science Projects

Western honey bees Apis mellifera are vital pollinators which play a significant role in global food security. Honey bees are faced by numerous environmental pressures including lack of forage which lead to large losses annually of managed honeybee colonies. To offset these pressures, many beekeepers manage colonies with the addition of artificial diets, many of which contain products that do not meet the nutritional requirements needed by honey bees or require large amounts of resources to grow. Recent literature has indicated that algae may be a viable nutritional resource for honey bees, meeting the nutritional requirements needed, requiring less resources, …

Epigenetic Regulation Of Insect Development, Yaoyu Jiao

Theses and Dissertations--Entomology

Insects undergo a series of distinct life stages such as egg, larva and pupa to develop into mature adults capable of reproduction throughout their life cycle. In the larval stage, insects experience the fastest growth with voracious feeding and multiple cuticle shedding resulting in hundreds-of-fold increasing of size. During metamorphosis, insects stop increasing body size but go through dramatic tissue transformation, developing wings and other adult features. The characteristic mode of insect development, especially the metamorphosis, makes insects the most successful group of animals on the earth. However, the epigenetic mechanisms behind insect development remain elusive. Studying the epigenetic regulation …

Foraging Behavior In The Eastern Subterranean Termite, Reticulitermes Flavipes (Kollar) (Isoptera: Rhinotermitidae), Anugerah Fajar

Theses and Dissertations--Entomology

Foraging is essential for survival, but it can be unpredictably dangerous due to organismal interactions like competition and predation to various environmental factors. Animals have come up with strategies to safeguard foraging. Social insects, with their elaborate division of labor, have developed sophisticated systems of foraging task allocation that allow them to capitalize resources beyond their competitors. In this thesis, I delve into the subjects of foraging behavior, allocation strategies, and the genetic basis of foraging in the eastern subterranean termite, Reticulitermes flavipes, the most widely distributed termite species in North America and one of the most economically important …

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

This study determined the effectiveness of rosemary extract on the shelf life of ground beef patties under different retail display conditions. Ground beef patties were produced from an 85%:15% blend (lean:fat). Patties were formed from batches of control or amended with rosemary extract. Patties were individually packaged using overwrap. Groups were assigned into one of two lighting groups (3000K and 3500K). Patties were placed in a simulated retail display for 5 d under continuous lighting and rotated once a day. Lipid oxidation and color samples were taken each day. Relating to lipid oxidation, there was no three-way interaction between display …

Understanding The Effects Of Age, Environmental Conditions, And Placement On Cockroach Gel Bait Performance, Isabelle Lucero

Theses and Dissertations--Entomology

Cockroach baits are one of the most effective tools used for German cockroach (Blattella germanica L.) control. This is due in part to the number of cockroach baits on the market with various matrix compositions and active ingredients, aiding in the control of resistant (physiologically and behaviorally) cockroach populations through bait rotation. However, it remains unclear how cockroach gel baits perform over time and under different environmental conditions. Therefore, we aged six cockroach gel baits for varying times (24 hours, one month, three months, six months) and at three relative humidities (15%, 40%, and 80%), and tested their performance …

Mechanisms Of Rnai In Insects, Jin Mo Koo

Theses and Dissertations--Entomology

RNA interference (RNAi) mechanism is found in many eukaryotes and animal cells, with its endogenous functions as defense against transposable elements and viruses, as well as post transcriptional regulation of gene expression. Since its first discovery, RNAi has contributed enormously as a reverse genetic tool for functional genomic studies. In application, RNAi is used in therapeutics, as well as agricultural crop and livestock protection. Yet, for the wider application of RNAi, improvement of its potency and delivery technologies is needed. Deeper mechanistic understanding of every step of RNAi, from cellular uptake of RNAi trigger molecule to targeted mRNA degradation is …

Costs And Benefits Of Integrating Poultry Into Cover Crop - Vegetable Rotations, Viktor Halmos

Theses and Dissertations--Entomology

Integrated livestock systems were once common leading up to the 20th century where livestock generated manure that was then used to fertilizer crop production in a closed- or semi-closed system. However, with the industrialization of agriculture in the mid to late 20th century, specialization drove simplified systems that segregated livestock from cropping systems. This segregation led to nutrient surpluses occurring in livestock operations, and nutrient demands in cropping systems creating a plethora of environmental issues. With the increased awareness of environmental issues, a renewed interest in integration has driven producers and researchers to experiment with integration again. For research, the …

Surveillance For Ticks And Tick-Borne Pathogens In Kentucky, Anna Rosalee Pasternak

Theses and Dissertations--Entomology

Tick-borne diseases are an emerging threat to human and animal health. In Kentucky, tick-borne disease surveillance has identified rising incidences of spotted fever rickettsiosis, ehrlichiosis, and Lyme disease. Since these diseases occur through the bites of infected ticks, effective prevention efforts are reliant upon knowing where the risk of exposure to tick bites exists. Historical data on tick distribution in Kentucky is variable, with very little reported on a statewide scale, leaving vector control workers, public health personnel, physicians, veterinarians, and others to rely on outdated, intermittent, or out-of-state information. In my dissertation, I surveyed ticks and select tick-borne pathogens …

Landscape Influences And Preventive Management For Drosophila Suzukii In Small Fruit Crops, Ryan William Kuesel

Theses and Dissertations--Entomology

Small fruit production has been greatly challenged by the repeated invasion of non-native arthropod pests, impacting economic feasibility, and increasing the need for insecticides. Spotted wing drosophila (Drosophila suzukii (Matsumura)) is the most recent invasive pest of small fruits. It causes damage by ovipositing beneath the skin of ripening fruits. Its wide-spread distribution and development of resistance to insecticides has resulted in the need for improved alternative management strategies for small fruit growers.

My surveys of D. suzukii at thirteen blackberry (Rubus fruticosus L.) and raspberry (Rubus idaeus L.) fields found that while D. suzukii was present …

Ecological Risk Assessment Of Transgenic Conditional Lethality Systems For Genetic Biocontrol Strategies, Fernan Rodrigo Perez-Galvez

Theses and Dissertations--Entomology

Genetic strategies of insect pest control are receiving increased interest due to recent advances in genetic engineering. By introducing alleles that make males functionally sterile, genetically modified (GM) insects can be used in area-wide pest management programs similar to the Sterile Insect Technique (SIT). Genetic control strategies carry several potential benefits, including improved efficacy and specificity, lower operation costs, and reduced dependence on chemical insecticides, but their use is still controversial despite extensive technical documentation indicating their innocuity to humans and the environment. This hesitation is likely due to the novel nature of the approach.

While the first field applications …

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

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 …

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 …

Rice Biomass Response To Various Phosphorus Fertilizers In A Phosphorus-Deficient Soil Under Simulated Furrow-Irrigation, Jonathan B. Brye, Kristofor R. Brye, Diego Della Lunga

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

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).
