Elevated Substitution Rates Among Wolbachia-Infected Mosquito Species Results In Apparent Phylogenetic Discordance., James E. Russell, Michael Saum, Rebekah Williams May 2022

Elevated Substitution Rates Among Wolbachia-Infected Mosquito Species Results In Apparent Phylogenetic Discordance., James E. Russell, Michael Saum, Rebekah Williams

Georgia Journal of Science

As one of the most widely distributed bacterial cytoplasmic symbionts on earth, Wolbachia pipientis Hertig serves as a model organism for the understanding of host-symbiont interactions. Many mosquito species are infected with Wolbachia strains that induce a form of reproductive manipulation called cytoplasmic incompatibility, in which infected females gain a reproductive advantage over uninfected females in mixed infection populations. The selective advantage of cytoplasmic incompatibility often results in a population sweep of Wolbachia and co-transmitted mitochondrial genomes. Mitochondrial evolution and phylogenetic inferences drawn from mitochondrial gene sequences are thus potentially compromised by reproductive manipulating symbionts, like Wolbachia. Our initial analyses ...


Economic Implications Of The Mexican Fruit Fly Infestation In Texas, Samuel D. Zapata May 2022

Economic Implications Of The Mexican Fruit Fly Infestation In Texas, Samuel D. Zapata

The Journal of Extension

The Texas citrus industry is threatened by the presence of Mexican fruit fly. The objective of this study was to estimate the economic losses caused by this invasive pest. Economic impact is estimated in terms of loss in revenue and increase in operating costs. Under current quarantined areas and pest management strategies, the Texas citrus industry could experience an annual economic loss of $5.79 million. The analysis was extended to evaluate the economic impact associated with different quarantined area scenarios. This article can be used to increase awareness and adapted to estimate the economic impact of emerging invasive pest ...


A Needs Assessment Survey Of Southern California Pest Management Professionals, Siavash Taravati May 2022

A Needs Assessment Survey Of Southern California Pest Management Professionals, Siavash Taravati

The Journal of Extension

Pest Management Professionals were surveyed in training workshops/meetings in Southern California between 2015 and 2017 to understand their needs, challenges, and view of integrated pest management. The most encountered pests by pest control technicians were ants, cockroaches, rodents, spiders, termites, and bed bugs. The most challenging pest groups to control were bed bugs, cockroaches, ants, and rodents. The main challenges that professionals faced in doing their work were regulations, followed by managing pests, and customer-related problems. Most participants had a favorable view of IPM. However, they faced several challenges in implementing IPM, among which customer-related issues were the most ...


Trophish: Building A Global Database Of Freshwater Trophic Interactions, Jacob M. Ridgway May 2022

Trophish: Building A Global Database Of Freshwater Trophic Interactions, Jacob M. Ridgway

Honors Thesis

Freshwater management and research frequently use the trophic data of freshwater fishes. Despite this fact, it is difficult to perform a simple search of dietary information for any one fish species. FishBase represents, to our knowledge, the largest compilation of freshwater dietary information to date. However, it excludes a large portion of the ecological literature due to its development taking place prior to the creation of most modern scientific search engines. Our project (TroPhish) is building upon FishBase by digitizing approximately 130 years of data from the fish predation literature. Data from the primary and grey (e.g. theses, dissertations ...


Site-Specific Pest Management In Nebraska Corn And Soybean Production Systems, Zachary D. Rystrom May 2022

Site-Specific Pest Management In Nebraska Corn And Soybean Production Systems, Zachary D. Rystrom

Doctoral Documents from Doctor of Plant Health Program

Site-specific management (SSM) is widely used by farm producers to fertilize their fields. However, whole field management is currently practiced in integrated pest management (IPM). Site-specific management and agricultural technology can improve IPM especially when precision application of inputs can reduce selection pressure on pest populations, benefit the environment, or save costs of inputs. There is potential for site-specific pest management (SSPM) where pests, or environments vary spatially, and recommended management practices can be applied with precision. Three case studies are evaluated for SSPM to be applied in Nebraska corn and soybean production systems including corn rootworm, preemergence herbicides, and ...


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 ...


First Line Of Defense: Role Of Surface Waxes In Sorghum Defense Against Aphids, Juan David Betancurt Cardona May 2022

First Line Of Defense: Role Of Surface Waxes In Sorghum Defense Against Aphids, Juan David Betancurt Cardona

Dissertations and Student Research in Entomology

Since 2013, the sugarcane aphid (SCA; Melanaphis sacchari) has become a devastating pest in sorghum (Sorghum bicolor) in the United States. Efforts to mitigate this pest and contain its rapid population growth have increased recently. Host plant resistance (HPR) is an effective and environmentally friendly strategy to reduce aphid populations in this crop. Many factors make SCA a challenging pest to control. For example, SCA can overcome drastic climatic changes, which allows them to successfully colonize sorghum plants at different developmental stages.

Epicuticular waxes (EW) constitute the first point of contact between plants and their environment. EW differ in their ...


Interactions Between Resistance Genes In Wheat Triticum Aestivum L. And Wheat Curl Mite Populations Aceria Tosichella Keifer (Eriophyidae), Tran Kim Ngan Luong May 2022

Interactions Between Resistance Genes In Wheat Triticum Aestivum L. And Wheat Curl Mite Populations Aceria Tosichella Keifer (Eriophyidae), Tran Kim Ngan Luong

Dissertations and Student Research in Entomology

Wheat curl mite (WCM) (Aceria tosichella Keifer) is a major pest of winter wheat (Triticum aestivum L.), being the only known vector of three damaging plant viruses, Wheat streak mosaic virus, Triticum mosaic virus, and High Plains wheat mosaic virus. This wheat-mite-virus complex causes significant yield loss globally. Management has been mostly through cultural practices to reduce mite build up in volunteer wheat, thereby reducing the spread of viruses. Host plant resistance to WCM has also been used as an important management strategy for this wheat-mite-virus complex. However, WCM is a cryptic species complex, resulting in great variability in WCM ...


Native And Non-Native Ant Impacts On Soil Microbes, Hannah A. Stewart May 2022

Native And Non-Native Ant Impacts On Soil Microbes, Hannah A. Stewart

Biology Theses

Organisms produce chemical weapons for defense, but target organisms can develop resistance. In their introduced range, non-native species may bring “novel weapons” against which native organisms have not co-evolved resistance. The invasive European fire ant (Myrmica rubra) may have brought antimicrobial secretions to the Northeastern United States that are novel weapons against native fungal and bacterial soil organisms. I hypothesized that M. rubra would better inhibit seed pathogens resulting in greater emergence of native myrmecochorous Viola sororia seeds and, as a side effect, more strongly inhibit arbuscular mycorrhizal fungi than a native seed dispersing ant (Aphaenogaster picea). I also expected ...

Identification Of A Potential Pathway Of The Exotic Black Weevil (Coleoptera: Curculionidae) In South Korea, Sohee Kim, Seon Woo Lee, Soo-Jung Suh

Insecta Mundi

The black weevil, Aclees taiwanensis Kôno (Coleoptera: Curculionidae), is one of the primary pests of fig trees in southeastern Asia and southern Europe. Thought to be of subtropical and tropical Asian origin, including China, the weevil was first found in southern areas of South Korea in July 2020. Subsequently, it was found in the following five cities: Haenam, Hampyeong, Jindo, Sinan, and Tongyeong (RDA 2020). Attempts to trace a possible pathway for the exotic black weevil suggested that this species probably followed pathways of illegal importation of infested plants from Taiwan and was unintentionally introduced into South Korea based on ...

Use Of Intramodal Odor Cues In Shelter Recognition By An Amblypygid, Nathan Bostelman Apr 2022

Use Of Intramodal Odor Cues In Shelter Recognition By An Amblypygid, Nathan Bostelman

Honors Projects

Amblypygids are nocturnal arthropods which live in cluttered habitats and possess the ability to navigate home after displacements of up to ten meters. Homing amblypygids rely on olfactory and tactile information gathered by their antenniform legs to navigate successfully. Given that odor signals encountered in nature are complex and dynamic, navigation via olfaction presents unique challenges related to signal uncertainty. To understand how amblypygids perceive perceive complex odors and what they learn from them, individuals of the subtropical amblypygid P. marginemaculatus were trained to associate a blend of two odors with a shelter and tested on three treatments: the reinforced ...


Using Conservation Genetics To Inform Reintroduction Of The Endangered Mottled Duskywing (Erynnis Martialis), Shayla Kroeze Apr 2022

Using Conservation Genetics To Inform Reintroduction Of The Endangered Mottled Duskywing (Erynnis Martialis), Shayla Kroeze

Electronic Thesis and Dissertation Repository

Habitat loss and climate change have caused declines in species diversity and abundance globally, including in butterflies which are important components of many ecosystems. Reintroductions are increasingly used to reverse diversity loss but are most effective when informed using genetics. I developed 24 microsatellites and characterized genetic structure and diversity of the endangered Mottled Duskywing (Erynnis martialis) in Ontario and neighbouring provinces and states. These were used to inform a planned reintroduction in Ontario. Populations had moderate levels of genetic diversity, however all but the largest populations may be subject to appreciable levels of genetic drift. Populations more than 8 ...


Non-Native Coccinellid Beetles And Land Use Abundance Patterns In The Quad Cities Region, Jack Hughes, Tierney Brosius, Michael Reisner Apr 2022

Non-Native Coccinellid Beetles And Land Use Abundance Patterns In The Quad Cities Region, Jack Hughes, Tierney Brosius, Michael Reisner

Biology: Student Scholarship & Creative Works

Harmonia axyridis was introduced in 1916. This species of coccinellid beetle is considered a desirable species for agriculture practices because of its ability to control pests. There is increasing evidence that H. axyridis may be outcompeting native species which could be contributing to the decline of some species that are disappearing from the landscape. Harmonia axyridis has a large migration range of 2 Km enabling the species to affect a large area of land. Invasive species often increase in abundance in urban landscapes which may be the case with H. axyridis. During the summer of 2021 we investigated H. axyridis ...

Ant-Lanta: Ant Diversity As A Proxy For Ecosystem Health, Sofia Cuenca Rojas, John Paul Hellenbrand, Clint Penick

Symposium of Student Scholars

Ants are found across a wide range of habitat types and play a crucial role in supporting ecosystem health. Because of this ubiquity, ants are considered an indicator species – one whose diversity in an ecosystem can be used as a proxy for ecosystem health. Our study examines the presence of ants across an urban gradient in Atlanta to understand how urbanization may be affecting our local community inhabitants. A total of 48 Sites were organized into three groups: Urban Managed Land, Urban Park, and Urban Forest. Sites were grouped based on ground cover percentages. We used bait samples to measure ...

New Ant In The Big City: Known Natural History Of Lasius Cf. Emarginatus In Its Native Range And Potential Impacts Of Recent Us Introduction, Samantha M. Kennett, Clint A. Penick

Symposium of Student Scholars

New York City has been the site of introduction for some of North America’s most damaging invasive pests, from chestnut blight to the Asian long-horned beetle. Despite these cautionary examples, there has been no formal tracking of a newly introduced ant species, Lasius cf. emarginatus, which has quickly become among the most common species in the city. Sometime between the first ant diversity survey of New York City in 2006 and the second in 2011,L. cf. emarginatus was introduced and quickly became established in the most urban habitats with the highest human contact. In contrast to other urban ...

Urban Surveying Of Bees And Wasps And Conscious Management, Sofia Castro, Grace Cope, Francis Mullan, Jaden Keys

Symposium of Student Scholars

Pollinators are integral to the functioning of urban ecosystems and agriculture yet face decline from habitat loss and fragmentation associated with urbanization. Recently, a growing number of urban universities have taken steps to ensure their campuses support pollinators. Kennesaw State University (KSU) is a semi-urban school located in the unique ecological area between the biodiversity hotspot of the Southeastern Appalachians and the urban space of Atlanta, Georgia. Before the present study, no survey had been conducted to determine what pollinators and associated floral resources exist on the school’s grounds. Thus, we present the first inventory of pollinators and the ...


From Individuals To Communities: The Effect Of Climate Change On Ectothermic Predators, Matthew Lawrence Meehan Apr 2022

From Individuals To Communities: The Effect Of Climate Change On Ectothermic Predators, Matthew Lawrence Meehan

Electronic Thesis and Dissertation Repository

The living components of ecological systems exist within a nested hierarchy, consisting of individuals, populations, and communities. Because of this nestedness, climate change can greatly impact ecological systems, as whole-organism metabolic and physiological demands change for ectotherms under warming, the effects of which may compound with every succeeding level. Therefore, a multi-level approach can better isolate how climate change will reshape ecological systems. In my doctoral research, I used feeding and mesocosm experiments to examine how climate change affects ectothermic predators at the individual-, population-, and community-level, using mesostigmatic mites (Arachnida: Parasitiformes) as my model predator. My research objectives were ...


Assessing The Influence Of Urban Greening On Urban Arthropods, Brendon Lawrence Apr 2022

Assessing The Influence Of Urban Greening On Urban Arthropods, Brendon Lawrence

Scholars Week

Green Heart is an urban greening experiment in Louisville, KY seeking to create new urban green spaces to ultimately increase air quality and improve human health. Changes in biodiversity in response to urban greening may influence human health via multiple hypothesized pathways including reducing harm (e.g. medicine provisioning), restoring capacities (e.g. reductions in stress), building capacities (e.g. increasing activity outdoors), and causing harm (e.g. zoonotic diseases). Arthropods are one component of diversity that may influence human health via each of these pathways. However, few studies have assessed the influence of Arthropod diversity on human health. Thus ...

Spongy Moth (Lymantria Dispar Dispar Linnaeus), Ann Mull, Lori R. Spears

All Current Publications

Spongy moths (Lepidoptera: Erebidae) are invasive leaf-eating (defoliating) pests that threaten trees and shrubs in urban, suburban, and rural landscapes. The spongy moth was accidentally introduced to the U.S. in 1869 by an amateur French entomologist in Massachusetts who sought to establish a hardier American silkworm industry. These moths now commonly occur in the northeastern U.S. and are also found in parts of Illinois, Indiana, Michigan, Minnesota, North Carolina, Ohio, Virginia, West Virginia, Wisconsin, California, Oregon, and Washington. In Utah, according to the Utah Department of Agriculture and Food (2021), the spongy moth is anticipated to survive and ...

The red admiral butterfly, Vanessa atalanta (Linneaus, 1758) (Lepidoptera: Nymphalidae) is a globally distributed species and model organism for studying migration patterns and effects of climate change. Most previous red admiral research focused on wild populations. Establishing laboratory colonies allow for experimentation with a multitude of lab-based plant-insect interactions. We describe red admiral butterfly life history and laboratory rearing methods.


Rediscovery Of Gnoriste Macra Johannsen In Wisconsin (Diptera: Mycetophilidae: Gnoristinae), Daniel K. Young Apr 2022

Rediscovery Of Gnoriste Macra Johannsen In Wisconsin (Diptera: Mycetophilidae: Gnoristinae), Daniel K. Young

The Great Lakes Entomologist

Gnoriste macra Johannsen was described from Whitefish Bay, Wisconsin in 1912. The type locality is now a highly residential region a few miles north of the center of Milwaukee. Herein, collection events are reported for G. macra from Sauk County in southcentral Wisconsin. These new records, nearly a century after the only other literature record, indicate the species still thrives in Wisconsin though likely extirpated from the type locality. The specimens were recovered from unbaited Townes Malaise traps during mid- to late May, 2006 and 2020. Cranial anatomy and functional morphology of the head suggests G. macra may be a ...
