Concepts In Animal Parasitology, Chapter 69: A Short Introduction To Marine Parasitology: Marine Parasites Of Economic And Medical Importance [Auxiliary Concepts], Klaus Rohde, Robin M. Overstreet

Concepts in Animal Parasitology

Chapter 69 in Concepts in Animal Parasitology, S. L. Gardner and S. A. Gardner, editors. 2024. Zea Books, Lincoln, Nebraska, United States

Introduction

Parasitism, in this chapter, is defined as “a close association of two organisms, in which one—the parasite—depends on the other—the host—deriving some benefit from it. The benefit is often food” (Rohde, 2005b). Many bacteria, viruses, and fungi are parasitic but usually not studied by parasitologists sensu stricto; they are the domain of microbiologists. Parasites as defined here do not always harm their host; the border between so-called genuine parasites and other symbionts such as commensals is often …

Monarch Butterfly (Danaus Plexippus) Oviposition Preferences And A Survey Of Fungal Pathogens On Native Milkweeds (Asclepias) Of The Northern Great Plains, Grace Damiano

Electronic Theses and Dissertations

North American monarch butterfly (Danaus plexippus) populations are experiencing significant declines due to habitat loss caused by land use changes. Much of the American Midwest where milkweed, the only host plant of the monarch butterfly, was once much more abundant has been converted to a predominantly agricultural landscape. There are nineteen species of milkweed native to the northern Great Plains region occupied by South Dakota, North Dakota, and Minnesota. Some of these milkweed species may be preferable to monarch butterflies for different reasons, including morphological factors such as stem length, species-level chemical factors, and temporal factors. As monarch …

The Choice Is Hers: Floral Preference And Habitat Use Of Early Season Queen Bumble Bees In Restored Ecosystems, Kathryn E. Mccabe

Graduate Research Theses & Dissertations

Restored ecosystems play a vital role in providing a sanctuary for native flora and fauna, offering crucial habitat and resources for many at-risk and declining taxa. Ensuring optimal functionality of these restorations is essential to supporting taxon like bumble bees. While many studies have focused on understanding the needs of bumble bees, much of this effort has relied on information gathered during their peak foraging season when workers are abundant, thus, neglecting other critical life stages, such as emerging spring queens. In this study, I investigated how spring queen bumble bees use three types of restored habitats (woodland, edge, and …

Longevity,Feeding Behavior, And Egg Production Of Adult House Flies (Musca Domestica) Provided With Potential Farm Foods, Anna Elise Grimenstein

Graduate Research Theses & Dissertations

House flies (Musca domestica) are cosmopolitan pests to both humans and livestock, and they can vector many diseases. House flies are especially associated with livestock facilities, as adult flies lay eggs in rotting organic matter such as manure. While it is understood that the diet an adult fly receives can affect biological parameters such as longevity and egg production, not much research has been done to address foods that are accessible to house flies in their natural habitat. The present study examined the longevity, feeding behavior, and egg production rates of adult house flies given different foods they would have …

Endophytic Fungi Associated With Galls And Host Plants Of Asphondylia Borrichiae (Diptera: Cecidomyiidae), Shannon Lynn Sharpe

UNF Graduate Theses and Dissertations

Asphondylia borrichiae, like other gall-forming gnats, are obligate symbionts to the endophytic fungi (EF) they deposit when laying eggs. Asphondylia spp. and EF are important biocontrol agents, yet details surrounding their diversity, life cycles, and host interactions remain poorly understood. Galls and leaf-stem tissues from two host plants were surveyed to identify and compare EF diversity between the host tissues and species of A. borrichiae. Identification of 114 isolates was carried out by sequencing the internal transcribed spacer (ITS 1/4 primers). Pairwise alignments in multiple genetic databases were bolstered by phylogenetic analyses using maximum parsimony and maximum likelihood …

Investigation Of L-Serine Synthesis And Transport As Stabilizing Feedback Mechanisms Within The Tsetse-Wigglesworthia Symbiosis, Ryan Phillips

Graduate Theses, Dissertations, and Problem Reports (ETD)

Tsetse flies (Glossina morsitans), which are the obligate vectors of Old-World trypanosomes (Trypanosoma spp.) that cause African trypanosomiasis, have a bacteriome that houses the intracellular endosymbiont Wigglesworthia glossinidia. The ancient coevolution of these species has led to the integration of Wigglesworthia metabolism into tsetse physiology and a subsequent reliance on nutrient exchange for maintaining the fitness of both partners. The establishment of this obligate mutualism has facilitated the emergence of feedback mechanisms that stabilize the symbiosis, such as that which involves the exchange of L-serine and B vitamins. The Gammaproteobacteria Wigglesworthia supplement B vitamins lacking …

Transcriptional Induction Of Immune Pathway Genes And Subsequent Antibacterial Activity In The Digestive Tract Of The Cat Flea (Ctenocephalides Felis)., Katie A. Weber

College of Graduate Studies: Theses & Dissertations

Fleas (Order Siphonaptera) are ectoparasites that serve as vectors of several human diseases (cat scratch disease, flea-borne spotted fever, murine typhus, and plague). Typically, these pathogens are acquired through the ingestion of a host-derived bloodmeal; thus, the lumen of the gut is the first barrier encountered by imbibed pathogens. During the early stages of infection, microbes come into contact with surrounding midgut epithelial cells which trigger a series of host responses to combat local infection. Specifically, pathogen recognition leads to intracellular signaling and an increase in the production of antimicrobial peptides (AMPs) via the IMD and Toll immune pathways. While …

There has been continuous and growing interest in edible insects. Worldwide, various levels of insect farming are emerging, ranging from small domestic farms to vertical farms reaching heights of 36 meters, accommodating several million growing insects. The appeal of insects lies in their ecological benefits, as they contribute to the valorization of unde-rutilized organic residues while requiring minimal space and water. The selection of insect species is influenced not only by their biology and behavior but also by local preferences and customs, varying with the scale of production and geographi-cal location. This review article aims to provide an updated overview …

All Peer-Reviewed Publications

With the ongoing global anthropogenic climate change, a silent war rages in forests, the lungs of the earth. Invasive pathogens and insect pests are decimating native trees, compromising ecological function, biodiversity, and ecosystem services. Many of the processes surrounding successful biotic invasions are broad and have been previously analyzed (Hobbs et al., 2006; Blackburn et al., 2011). For invasive insect pests and pathogens, globalization, the rise in human population and associated environmental disturbances are recognized as fundamental drivers of introduction of propagules of non-native species to novel environments. Superior tolerance of extreme climate environments, in particular temperature, is also associated …

Tsetse flies and trypanosomosis significantly impact bovine production and human health in sub-Saharan Africa, exacerbating underdevelopment, malnutrition, and poverty. Despite various control strategies, long-term success has been limited. This study evaluates the combined use of entomopathogenic fungi (EPF) and the sterile insect technique (SIT) to combat tsetse flies. Eleven EPF isolates were tested against teneral males of Glossina pallidipes, focusing on mortality rates, radial growth, and impacts on fly fitness. Temperature effects on conidial growth, sporulation, and spore yield of SIT-compatible/tolerant strains were also assessed. The fungal isolates significantly influenced mortality rates in both unirradiated and irradiated (SIT-treated) males (p <  0.0001). Metarhizium anisopliae strains ICIPE 20, ICIPE 32, ICIPE 41, ICIPE 62, ICIPE 78, and Beauveria bassiana ICIPE 603 showed higher SIT compatibility/tolerance with LT50 values of 11–30 days, compared to other more virulent isolates with LT50 values of 4–9 days. Temperature significantly affected the radial growth of SIT-compatible EPF strains (p <  0.0001), with M. anisopliae ICIPE 78 exhibiting the fastest conidia growth at 25°C. Spore yield varied significantly across temperatures (15–40°C), and the thermal range for conidia germination of SIT-compatible strains was 8.1–45.4°C, with an optimal range of 26.7–31.1°C. Moreover, infected unirradiated females and irradiated males (donors) successfully transmitted conidia to untreated flies (receivers) without significant differences in survival rates (p = 0.6438) and no observed sex dimorphism. Our findings highlight the potential of combining EPF and SIT as a novel dual approach that could effectively and synergistically suppress tsetse fly populations.
