Genotypic Variation And Wilting Speed Affect Soybean (Glycine Max) Germination And Growth, Adriana Peissel, Jessica Ayala, Rupesh Kariyat
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Soybean (Glycine max) is one of the most important agricultural crops in the world due to its value as a major source of protein and oilseed production. Soybean is extremely sensitive to drought and experiences severe reductions in yield when there is a reduction in water availability. Canopy wilting speed is a trait linked with water use efficiency (WUE) in soybeans. Slower wilting canopies indicate greater WUE, while faster wilting canopies indicate lower WUE. Previous studies have explored the variation of plant physiological traits across wilting speeds on a smaller scale, but ultimately, a more extensive assessment is …

Soil salinity is a significant abiotic factor that impedes sustainable crop production in key agricultural regions worldwide. Saline cultivation adversely affects soil quality, whereas the use of saline water for irrigation disrupts the physiological and biochemical processes of plants. Continuous irrigation with high salt concentrations leads to a gradual buildup of soil salinity, thus hindering optimal plant growth and development. Consequently, there is a growing emphasis on breeding salinity-tolerant cultivars of various crops. In this study, 71 tomato accessions sourced from 20 countries and provided by the US Department of Agriculture were evaluated under controlled greenhouse conditions and subjected to …

Pathogens And Parasites Of Feral And Managed Honey Bee, Apis Mellifera, Colonies From Oklahoma, Allen Szalanski
Entomology and Plant Pathology Faculty Publications and Presentations
Managed honey bee populations in the United States have been under stress over the past several decades, probably due to the interaction among multiple biotic and abiotic stressors. While most research has focused on national surveys of honey bee pathogens and parasites, state-specific studies that include both managed and feral honey bee populations may offer additional insights into the factors that contribute to the decline of honey bees. We conducted a survey to detect parasites and pathogens from feral and managed honey bees in colonies in Oklahoma. A total of 253 (89 managed and 164 feral) honey bees from these …

Genetic Variation Of Rice Stink Bugs, Oebalus Spp. (Hemiptera: Pentatomidae) From Southeastern United States And Cuba, Allen Szalanski
Entomology and Plant Pathology Faculty Publications and Presentations
The rice stink bug, Oebalus pugnax (F.; Hemiptera: Pentatomidae) has been a pest of rice in the United States since the 1880s. Besides this species, there now are two invasive Oebalus species, O. ypsilongriseus (De Geer) and O. insularis Stål, which are found in Florida. Genetic variation of these economically important species is unknown, limiting our understanding of Oebalus evolution and demography. Here we provide the first population-level investigation of genetic diversity in these species. Ninety two adult stink bugs were collected from the southeastern United States (Arkansas, Mississippi, Florida), and Cuba. A region of the mitochondrial DNA cytochrome oxidase …

Soybean looper (SBL), Chrysodeixis includens (Walker 1858) (Lepidoptera: Noctuidae), is one of the most damaging insect pests of soybean, Glycine max (L.) Merr., in the mid-south region of the United States, and causes significant economic losses to cotton, sunflower, tomato, and tobacco crops in the United States, Brazil, and Argentina. Soybean production in the southern region accounted for 15.5% of the total production in the United States, and yield losses due to invertebrate pests were 5.8%, or 1.09 million metric ton, in 2022. As insecticide resistance of SBL continues to rise, the lack of alternate control strategies is a serious …
Effects Of Fast And Slow-Wilting Soybean Genotypes On Plant-Herbivore Interactions, Jessica Ayala
Effects Of Fast And Slow-Wilting Soybean Genotypes On Plant-Herbivore Interactions, Jessica Ayala
Graduate Theses and Dissertations
Soybean [Glycine max (L.) Merr.] is one of the most important food crops in the world due to its multiple uses in agriculture sector. A major limiting factor in soybean production system is drought stress, causing up to 80% reduction in yield. Due to climate change and associated rise in ambient temperatures, water scarcity is a major concern in crop production, and consequently researchers are turning to soybean accessions that demonstrate better water use efficiency (WUE) traits. However, field grown soybean is also under severe pressure from insect herbivores, often accounting for a 30% reduction in yield. Among these, …

Rice Sucrose Non-Fermenting Related Protein Kinase (Snrk1) Has A Limited Role In Defense Against Fall Armyworm (Spodoptera Frugiperda), Devi Balakrishnan, Vibha Srivastava, Rupesh Kariyat
Entomology and Plant Pathology Faculty Publications and Presentations
Sucrose non-fermenting (SNF) related protein kinase 1 (SnRK1) is a master regulator of energy deprivation signaling, has also been implicated in abiotic and biotic stress regulation. SnRK1 promotes stress tolerance through metabolic and transcriptional changes and plays important roles in innate immunity against various pathogens. However, whether it plays a role against insect herbivory is not understood. To test this, using the wild type (with SnRK1) and snrk1 mutant lines in rice, we examined the potential role of SnRK1 in rice against the ruinous pest, Fall armyworm (FAW), Spodoptera frugiperda. We also investigated the response of FAW towards these lines …

Integrating Ecophysiology And Omics To Unlock Crop Response To Drought And Herbivory Stress, Insha Shafi, Manish Gautam, Rupesh Kariyat
Entomology Faculty Publications and Presentations
Introduction: Plants are constantly exposed to a diverse spectrum of environmental stressors that typically occur concurrently as multifactorial challenges, both spatially and temporally (Joshi et al., 2024). These stressors include abiotic stresses, such as drought, flooding, salinity, nutrient deficiencies, metal toxicity and extreme temperatures, as well as biotic pressures such as herbivory, pathogen attacks, and inter and intraspecific competition (Porter et al., 2020; González Guzmán et al., 2022). Drought and herbivory are arguably among the most critical factors that limit crop productivity in agricultural settings (Gautam et al., 2024), making it imperative to understand plant responses to their combined effects. …

Interactive Effects Between Bluetongue Virus Infection And Insecticide Exposures In Culicoides Sonorensis, Parker Mullins
Graduate Theses and Dissertations
Culicoides biting midges are common pests around the world of humans, livestock, and wildlife. In addition to nuisance blood feeding, they are also able to transmit pathogens to their hosts like bluetongue virus (BTV) and African horse sickness virus, which can be damaging in terms of both production economics and animal welfare. In order to protect humans and livestock from biting pests like Culicoides, a wide array of interventions is recommended, but chemical insecticides and repellent use are ubiquitous. For a multitude of reasons ranging from natural weathering of applied insecticides to the increase in resistance-associated mutations and behaviors in …
Effects Of Land Cover And Land Change On Monarch Butterfly Presence Across The Conus, Chris R. Burkhart
Effects Of Land Cover And Land Change On Monarch Butterfly Presence Across The Conus, Chris R. Burkhart
Graduate Theses and Dissertations
The decline of monarch butterfly populations (Danaus plexippus L.) over the past four decades, particularly in their overwintering habitats, has raised concerns about the species' conservation. Habitat loss and modification, particularly within the contiguous United States, are attributed as one of the key drivers of this decline. However, the specific impact of land use and land cover (LULC) changes on monarch distributions remains inadequately documented. This study integrates monarch observations from multiple sources spanning 2008 to 2019 with LULC data to analyze the relationship between habitat configuration and monarch presence. Using a randomized grid sampling approach, habitat configuration metrics were …

Toxicity And Risk Of Biopesticides To Insect Pollinators In Urban And Agricultural Landscapes, Joshua Chavana, Neelendra K. Joshi
Entomology Faculty Publications and Presentations
Pollinators play important roles in providing pollination services, maintaining biodiversity, and boosting crop production. Even though pollinators are essential to the environment and agriculture, their decline has been noted across multiple studies in the recent past. Both natural and anthropogenic factors have contributed to their decline. Much of the focus has been placed on climate change, habitat loss, pests and pathogens, and synthetic pesticides, but relatively little is known about the effects of biopesticides. Biopesticides are biological control agents derived from living organisms and are classified into three groups: microbial, biochemical, and plant-incorporated protectant-based products. Biopesticides are formulated similarly to …

Bark beetle outbreaks result in massive amounts of deadwood which are a significant carbon reservoir that can impact forest ecosystems. Additionally, bark beetle-introduced symbiotic fungi in beetle-generated deadwood can increase termite presence and feeding. This could alter decomposition rates and saproxylic communities of bark beetle-generated deadwood. However, the fate of bark beetle-generated deadwood after tree mortality has received little attention despite the possibility bark beetles could alter decomposition processes and deadwood residence times at landscape scales following outbreaks. We tested the hypothesis that beetle-attacked trees decompose faster than unattacked trees. In Honduras, and Mississippi and Arizona, USA, we felled one …

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Lotic waterways are vital for habitat, food, water, and flood protection, but urbanization poses a major threat to their integrity. Runoff from urban surfaces leads to pollution, flashiness, loss of biodiversity, and other symptoms, also known as Urban Stream Syndrome (USS). Streams can be restored in order to combat USS, but most restorations are not monitored, so their long-term effectiveness is unknown. This study quantitatively evaluated a decade-old stream restoration in Fayetteville, Arkansas, to assess its effectiveness in combating USS and achieving set restoration goals, and to gain insights for future restoration projects. Restoration goals included decreasing erosion and sedimentation, …

Evaluating Efficiency And Accuracy Of Three Texture Analysis Methods For Blackberry Fruit, Rhys M. Brock, Carmen Johns, Katelyn Lust-Moore, Margaret Worthington
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
A major objective of the University of Arkansas System Division of Agriculture (UADA) Fruit Breeding program is to improve the texture of blackberry (Rubus subgenus Rubus Watson). Blackberry varieties with improved fruit firmness transport and store well and may maintain superior quality under challenging postharvest conditions than softer varieties. Increased firmness may also make cultivars less susceptible to red drupelet reversion (RDR), a postharvest disorder of blackberries in which fully black drupelets revert to red after harvest. This research project aims to assess the efficiency and accuracy of three methods applied in evaluating blackberry firmness. The study compares instrumental analysis …

Expanded Range Of Nasutitermes Callimorphus Mathews, 1977 (Isoptera: Termitidae: Nasutitermitinae), Comparison With N. Corniger (Motschulsky, 1855) And N. Ephratae (Holmgren, 1910), And Synonymy Of N. Dasyopsis Thorne, 1989 Into N. Nigriceps (Haldeman, 1854), Allen Szalanski
Entomology and Plant Pathology Faculty Publications and Presentations
The imago of N. callimorphus is described for the first time. Nasutitermes callimorphus occurs from Mexico to Paraguay. Nasutitermes callimorphus is smaller in all measurements but generally resembles its widely distributed sympatric congeners, N. corniger (Motschulsky, 1855) and N. ephratae (Holmgren, 1910). Molecular phylogenetic analysis of a portion of the mitochondrial 16S rRNA gene and the COII mtDNA marker revealed that N. callimorphus forms a distinct clade using both maximum parsimony and maximum likelihood analysis. Unlike N. corniger and N. ephratae, N. callimorphus does not build epigeal or arboreal carton nests. We further regard N. dasyopsis Thorne, 1989 as a …
