Hormetic Ethanol Effects On Fitness And Attraction In Irradiated Aedes Aegypti, Kayden Robey, Gabriel Borg, Immo Hansen Apr 2026

Hormetic Ethanol Effects On Fitness And Attraction In Irradiated Aedes Aegypti, Kayden Robey, Gabriel Borg, Immo Hansen

The Agora

Sterile insect technique (SIT) is an increasingly important strategy for controlling mosquito populations while reducing reliance on chemical insecticides and genetically modified organisms. A major limitation of SIT is the reduced fitness and competitiveness of irradiated male mosquitoes, which can compromise population suppression efforts. This study investigates whether hormetic ethanol exposure improves post-irradiation fitness in Aedes aegypti males, a primary vector of dengue, chikungunya, and yellow fever. Adult male mosquitoes were fed either a standard sugar solution or a sugar solution supplemented with 5% ethanol prior to irradiation. Males were sterilized using X-ray irradiation at 50 Gy and assessed for …

Semiochemicals And Odorant Receptors Underlying Potato Cultivar Susceptibility And Resistance To Potato Tuber Moth, Ruipeng Chen, Wangtao Hu, Qin Hu, Junjie Yan, Jiao Yin, Fathiya M. Khamis, Yulin Gao, Walter S. Leal

All Peer-Reviewed Publications

Infestation of potato by the potato tuber moth (Phthorimaea operculella) varies markedly among cultivars, yet the chemical and molecular mechanisms underlying this variation remain poorly understood. Here, we combine field surveys, chemical ecology, functional genomics, and structural modeling to reveal how cultivar-specific volatile profiles shape moth oviposition behavior and pest outcomes. Field and laboratory assays identified marked differences in adult attraction, oviposition, and larval damage among potato cultivars, which correlated with distinct blends of emitted volatile organic compounds (VOCs). Behavioral analyses revealed that among other VOCs, trans-nerolidol and β-ionone act as attractants, whereas 3-carene and benzyl tiglate function as oviposition …

Modelling The Temporal Dynamics Of Microsporidia Mb Prevalence In Anopheles Mosquitoes Under Environmental Variability, Charlène N. Mfangnia, Matteo Pedercini, Henri E. Tonnang, Jeremy K. Herren

All Peer-Reviewed Publications

Releasing Microsporidia MB-positive mosquitoes is being investigated as a promising component of Integrated Vector Management (IVM) strategies for malaria control. In this study, we developed a System Dynamics model to replicate the observed interactions between humans, mosquitoes, the Plasmodium parasite, and the symbiont MB. The model accounts for the impact of environmental variables - such as humidity, rainfall, and temperature - on mosquitoes, Plasmodium, and MB, using exogenous inputs derived from daily climatic observations (rainfall, relative humidity, and temperature) recorded during the mosquito field surveys. We calibrate the model using data collected from Ahero in Kenya, available for 3 years …

Bluebird Bait: Quantifying The Attraction Of Ectoparasites To Nestling Eastern Bluebirds (Sialia Sialis), Ella Grace Bollinger Apr 2026

Bluebird Bait: Quantifying The Attraction Of Ectoparasites To Nestling Eastern Bluebirds (Sialia Sialis), Ella Grace Bollinger

ATU Scholars Symposium

Ectoparasites, such as mosquitoes (Culicidae), blackflies (Simuliidae), and biting midges (Ceratopogonidae), have been shown to reduce population viability by lowering post-fledging survival and decreasing the lifetime reproductive success of adult birds. This issue is particularly concerning for songbirds such as the Eastern Bluebird (Sialia sialis) because their nestlings are relatively naked and have limited mobility, making them highly vulnerable to attacks by biting flies. However, the specific mechanisms attracting ectoparasites to nests remain understudied. We hypothesized that biting fly and mosquito abundance would be significantly higher at active Eastern Bluebird nests than that of empty boxes and would increase with …

Developing A Range Prediction For The Imperiled Florida Harvester Ant (Pogonomyrmex Badius) Using Species Distribution Modeling, Noah Williamson Apr 2026

Developing A Range Prediction For The Imperiled Florida Harvester Ant (Pogonomyrmex Badius) Using Species Distribution Modeling, Noah Williamson

Honors Theses

The Florida Harvester Ant (Pogonomyrmex badius) was once widespread and commonplace throughout the sandhills of the Southeastern United States, providing key ecosystem services, such as seed dispersal and soil aeration. Over recent decades, however, Florida Harvester Ant populations have declined in some areas. Current literature postulates that Red Imported Fire Ants (RIFA), and the insecticides used to manage them, as well as further human encroachment onto their habitat, all likely contributed to Florida Harvester Ant population declines. Thus, to better protect these organisms, pursue data-driven conservation efforts, and guide management practices, more information about their nest site selection, as well …

All Peer-Reviewed Publications

Environmental transformation driven by human activity has profound implications for the ecology of mosquito vectors and the pathogens they transmit. This study investigated the influence of land-use change on mosquito assemblages, host-feeding patterns, and arbovirus infection across sylvatic-rural-peri-urban land-use types in Marigat subcounty, Rift Valley, Kenya. Adult mosquitoes were collected using CO₂-baited CDC light traps and BG-Sentinel traps across three sites: Kiborgoch conservancy (sylvatic), Ntepes village (rural) and Marigat town (peri-urban). Sampling was conducted during three sessions including September 2022, August 2023, and December 2023. The mosquitoes were morphologically identified to species, and indices of abundance, richness and diversity compared …

Seasonal Activity Pattern Of Ambrosia Beetles In Southeast Virginia, Umme H. Akter, Sajrim Chowdhury, Deborah A. Waller Mar 2026

Seasonal Activity Pattern Of Ambrosia Beetles In Southeast Virginia, Umme H. Akter, Sajrim Chowdhury, Deborah A. Waller

Knowledge and Creativity Expo

Ambrosia beetles (Curculionidae: Scolytinae) are wood-boring insects that influence forest ecosystems through fungal symbioses, rapid host colonization, and invasive species dynamics. Despite their ecological importance, seasonal activity patterns remain poorly characterized in southeastern Virginia. This study integrates field trapping and statistical modeling to examine species-specific seasonal activity across two forested sites in Norfolk, Virginia. Beetles were monitored using ethanol and essential oil-baited bottle traps alongside ethanol-soaked bolt traps. Overall abundance peaked in April, indicating strong early-season emergence. Ethanol-baited traps captured 3-7 times more beetles than essential oil traps, and negative binomial generalized linear models confirmed bait type as a significant …

Sandfly-borne phleboviruses cause febrile illness and neuroinvasive disease in humans. While infections are reported in the Mediterranean region, the discovery of previously unknown phleboviruses in sandflies from Kenya suggests a wider geographic distribution. Detection and characterization of novel phleboviruses are often hindered by low-quality and low-viral-load samples. We developed a capture-based target enrichment next-generation sequencing approach that showed a 99%-100% fold enrichment of viral genomes from primary material and provides a robust tool for generating complete genomes of both known and previously unknown viruses. From a collection of 15,652 sandflies in Kenya, we recovered seven complete coding sequences of Embossos, …

The Great Lakes Entomologist

Seasonal ponds often form after spring snowmelt in forests of the Great Lakes region. Although such seasonal ponds are common, few US states set buffer-width guidelines to protect them when harvesting the adjacent upland forest. The objectives of this study were to determine if the carabid beetle assemblages near seasonal ponds differed from those in the adjacent upland forests prior to any logging, and then if these assemblages changed in response to various levels of tree harvesting within and adjacent to the 15-m-wide buffers that surrounded the seasonal ponds. The traps were placed within the buffers at about 7.6 m …

The Modern Sisyphus Blows Leaves: Attitudes And Impacts Regarding Leaf Litter Removal On A Suburban Campus, A. C. Nony, M. R. Mcclung, M. L. Reid Mar 2026

The Modern Sisyphus Blows Leaves: Attitudes And Impacts Regarding Leaf Litter Removal On A Suburban Campus, A. C. Nony, M. R. Mcclung, M. L. Reid

Journal of the Arkansas Academy of Science

Leaf litter habitat disruption in suburban spaces stems from the prevalence of “lawn culture,” that is, the accepted societal norm that land immediately surrounding humans or meant for human recreational use should be clean, tidy, controlled, and aesthetically pleasing, above other considerations. When leaf litter on residential and recreational lawns is cleared, it removes vital habitat for organisms of several taxa, especially species that rely on litter as a moisture and temperature-controlled substrate for overwintering. We administered an opinion survey to students, staff, and faculty at Hendrix College, a highly residential and suburban campus in Conway, Arkansas, to assess views …

All Peer-Reviewed Publications

Low-coverage whole genome sequencing (lcWGS) combined with genotype imputation provides a cost-efficient alternative to high-coverage sequencing for large-scale genotyping. Although widely implemented in human and livestock genomics, this strategy has not yet been systematically optimized for insects of industrial importance. The black soldier fly (BSF, Hermetia illucens ) is increasingly used in global waste bioconversion and sustainable protein production, but genomic resources remain limited. Here, we develop the first BSF haplotype reference panel, containing ∼29.8 million high-quality SNPs from 168 high-coverage genomes, and benchmark imputation performance using a validation experiment in which 33 high-coverage individuals were down-sampled to low coverage …
