Potato production is hindered by soil degradation and nematode infestation. Mineral fertilizers and synthetic nematicides are costly and cause negative impacts on humans and the environment, while organic fertilizers are less effective for soil health and nematode management. This study demonstrates the contribution of black soldier fly frass fertilizer (BSFFF) in nematode suppression and potato productivity when compared to commercial mineral fertilizer, organic fertilizer (SAFI), and nematicide. The on-farm experiments consisted of eight treatments: BSFFF, SAFI, BSFFF+5%chitin, NPK+nematicide, 50%BSFFF+50%NPK, 50%SAFI+50%NPK, 50%BSFFF+5% chitin+50%NPK, and control (unfertilized soil). Results revealed that all fertilizer treatments significantly increased potato growth, number of tubers (34 …

Multi-floral foraging sources for honey bee (Apis mellifera L.) have been threatened by landscape changes and unsustainable farming practices. In East Africa, the biodiversity of forage resources that could support honey bees, especially in agricultural lands, remains least explored. This study investigated pollen diversity for honey bees in Yatta and Masinga Sub-counties in Machakos County, Kenya. Honey bee hives were installed on eight pumpkin (Cucurbita maxima Duchesne ex Lam) farms (one hive per farm) in two varying landscape vegetation classes (low and medium) based on normalized difference vegetation index (NDVI). Pollen traps were installed at the hive entrance and pollen …

Fire And Mammal Herbivory On Arthropods In The Protected Savannas: A Systematic Review, Ludzula Mukwevho, Mduduzi Ndlovu, Frank Chidawanyika Jan 2025

Fire And Mammal Herbivory On Arthropods In The Protected Savannas: A Systematic Review, Ludzula Mukwevho, Mduduzi Ndlovu, Frank Chidawanyika

All Peer-Reviewed Publications

Protected areas in the savannas are key global reserves for biological diversity, including arthropods. Fire and mammal herbivory disrupts the diversity of biological organisms that alternately affects the functioning of the ecosystem. The study presents a global synthesis review of arthropod responses to varying intensities of fires and mammal herbivory in the protected savannas. We hypothesise that the intensity of predetermined fires and mammal herbivory has cascading impacts on abundance, species richness and diversity of terrestrial arthropods in the protected savannas. A minimum selection criteria was used to collate relevant literature from electronic databases of previous studies performed in the …

Push–pull system intensification with vegetables (VIPPT) has contributed significantly in maintaining good control of lepidopteran pests and parasitic weeds with additional food and nutritional security benefits. However, the impact of integration of different rates of black soldier fly frass fertilizer (BSFFF) in the VIPPT to enhance productivity, has not been explored. This study investigated the effects of different BSFFF application rates on growth performance, pest infestation severity, diversity of natural enemies and yield of kale (Brassica oleracea L. var. acephala) grown under VIPPT in two agroecological zones. Plants were grown in soils amended with five different levels of BSFFF (0, …

Biology-Informed Inverse Problems For Insect Pests Detection Using Pheromone Sensors, Thibault Malou, Nicolas Parisey, Katarzyna Adamczyk-Chauvat, Elisabeta Vergu, Béatrice Laroche, Paul André Calatayud, Philippe Lucas, Simon Labarthe

All Peer-Reviewed Publications

Most insects have the ability to modify the odor landscape in order to communicate with their conspecies during key phases of their life cycle such as reproduction. They release pheromones in their nearby environment, volatile compounds that are detected by insects of the same species with exceptional specificity and sensitivity. Efficient pheromone detection is then an interesting lever for insect pest management in a precision agroecological culture context. A precise and early detection of pests using pheromone sensors offers a strategy for pest management before infestation. In this paper, we develop a biology-informed inverse problem framework that leverages temporal signals …

All Peer-Reviewed Publications

Aquaculture plays a critical role in global food security, with Nile tilapia (Oreochromis niloticus) recognized for its adaptability and robust growth. However, traditional feeds, heavily reliant on fishmeal (FM) and soybean meal, face economic and environmental challenges. In response, black soldier fly larvae meal (BSFLM) has emerged as a promising, nutrient-dense alternative. This review synthesizes existing literature on BSFLM’s nutritional profile and its suitability for Nile tilapia diets, while acknowledging that the data come from diverse independent studies conducted under varying environmental conditions and husbandry practices. BSFLM consistently provides high-quality protein (29.9%–48.2%), aligning with tilapia’s requirements, and is rich in …

Advances in next-generation sequencing have allowed the use of DNA obtained from unusual sources for wildlife studies. However, these samples have been used predominantly to sequence mitochondrial DNA for species identification while population genetics analyses have been rare. Since next-generation sequencing allows indiscriminate detection of all DNA fragments in a sample, technically it should be possible to sequence whole genomes of animals from environmental samples. Here we used a blood-feeding insect, tsetse fly, to target whole genome sequences of wild animals. Using pools of flies, we compared the ability to recover genomic data from hosts using the short-read sequencing (Illumina) …

All Peer-Reviewed Publications

The oriental fruit fly Bactrocera dorsalis is a highly destructive and invasive pest that threatens global horticulture, causing economic losses due to fruit damage and quarantine regulations. While attract-and-kill baits are widely used to suppress fly populations, these baits also impact many non-target species. To achieve ecological sustainability, our study aimed to develop a method that selectively targets female fruit flies. Using gas chromatography coupled to electro-antennal or palpal detection (GC-EAD/GC-EPD), we identified compounds that elicited responses in the maxillary palp and antenna of three different fruit flies including B. dorsalis, Ceratitis capitata, and Zeugodacus cucurbitae. As previous studies indicated …

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 …

Molecular Characterization Of Fungus-Arthropod Associations, Angie M. Martin Jan 2025

Molecular Characterization Of Fungus-Arthropod Associations, Angie M. Martin

Graduate Theses, Dissertations, and Problem Reports (ETD)

Arthropods, or phylum Arthropoda, are the largest group of animals, accounting for over three quarters of all animal records on NCBI Taxonomy. And yet, only 40% of all deposited sequences on NCBI Nucleotide come from arthropods. Clearly, arthropods are an understudied group of animals: they are small, often drab, and lead lives very alien to our own. Arthropods have chitinous exoskeletons, segmented bodies, and jointed appendages, and include crabs, barnacles, insects, spiders, and millipedes. Since the era of DNA based studies took off in the 1980s, DNA and other small molecules have been integral to our understanding of the Earth …

The Seasonality And Community Composition Of Mosquitoes At Turnbull National Wildlife Refuge, Jonathan Becerra

EWU Masters Thesis Collection

Characterizing mosquito species composition and seasonal dynamics is fundamental to understanding how mosquito communities change across time and space. This study examined the structure, temporal patterns, and spatial variation of the mosquito community at Turnbull National Wildlife Refuge (TNWR) using three years of CDC light-trap data (2017–2019). We applied multiple complementary analytical approaches—including presence/absence and CPUE models, annual and species-specific generalized additive models (GAMs), peak-timing ANOVA, and multivariate analyses (NMDS, PERMANOVA, and indicator species analysis)—to quantify species-level seasonality, phenological staggering, and community-level patterns across years and between two sampling locations (Gate and Headquarters). Across all model families, species identity and …

Evaluation Of Two Stem Boring Insects In South Dakota: A Survey Of Wheat Stem Sawfly And Determining The Impact Of Planting Date On Dectes Stem Borer Infestations In Sunflowers, Khuma Kumari Bhusal

Electronic Theses and Dissertations

Wheat, Triticum aestivum L., and sunflower, Helianthus annuus L., are major crops in South Dakota that are threatened by stem-boring insect pests capable of reducing yield and harvestability. In wheat, the wheat stem sawfly, Cephus cinctus Norton, has long been recognized as a destructive pest in the Northern Great Plains, yet its actual distribution within South Dakota remained uncertain. To determine its presence, a two-year survey was conducted across the state from 2023–2024, during which one to four wheat fields per county were sampled using standardized sweep net transects. Wheat stem sawflies were collected only from Harding and Perkins Counties …
