Can The Vegetation Structure And Composition In Urban Green Spaces Determine Diversity Of Green Lacewings (Neuroptera: Chrysopidae)?, Jose I. Martinez, Raiza J. Castillo, Adrián Ardila-Camacho, Charles V. Covell, José Isabel López-Arroyo, Francisco Javier Nava-Guízar

Insecta Mundi

Green spaces represent the only natural areas in several cities around the world, providing good shelters for the local fauna. Based on this premise, many ecological studies have been conducted focused on these areas. Most of these works are about insects, particularly butterflies and beetles. Our study is centered on a different group: green lacewings (Neuroptera: Chrysopidae). These insects exhibit a similar feeding behavior to some other groups, such as beetles. We estimated diversity, richness, distribution, abundance and similarity employing two methods: sweep netting and suction trapping. Also, oviposition hosts were identified in 20 different green spaces. Approximately 740 specimens …

Journal of Bioresource Management

Mosquitoes are considered as vectors of serious human diseases. The prevention of parasitic and arboviral vector-borne diseases is based mostly on vector control strategies. This control cannot be effective unless a strong knowledge of mosquito biology and distribution in the working area. In this context, and in order to improve the knowledge on the specific diversity of the culicids fauna in the region of Khenchela (northeast of Algeria), an inventory of mosquitoes was carried out for the first time in this region. Larval collection was conducted in various types of habitats through continuous monitoring of seven sites from May 2020 …

A New Species Of Epeolus Latreille, 1802 (Hymenoptera: Apidae) From Western North America, Thomas M. Onuferko, Cory S. Sheffield

Insecta Mundi

A new species of Epeolus Latreille, 1802 (Hymenoptera: Apidae)—E. emiliae Onuferko and Shef­field, new species—is described from North America west of the Great Plains. It is morphologically most similar to Epeolus autumnalis Robertson, 1902, a species known exclusively from east of the Rocky Moun­tains. DNA barcode sequences from representatives of E. autumnalis and E. emiliae share a barcode index number (i.e., BIN: BOLD:AAF2361), but the two species exhibit marked and consistent differences in integu­ment coloration and the patterns of pubescence on the metasoma, and their distributional ranges, based on known specimens, show no overlap. This discovery increases …


Understanding How Whole Genome Duplication In Plants Impacts Herbivore-Plant Interactions, Anne Curé May 2022

Understanding How Whole Genome Duplication In Plants Impacts Herbivore-Plant Interactions, Anne Curé

Dissertations - ALL

Herbivory by insect herbivores is a strong selective force in many communities. Although herbivore-plant interactions have been a focus of interest for decades, we are still exploring how large-scale genetic changes in the host plant alters their interactions with insect herbivores. One such prevalent change in plants is whole-genome duplication (WGD), or polyploidy, but we are still learning how WGD affects ecological interactions. In particular, studies of herbivory on polyploids have primarily focused on established polyploid plant populations. Although this approach has yielded exciting results that suggest WGD affects insect herbivores feeding on polyploids, this approach also confounds the effects …


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 …


Population Ecology Of A Caribbean Epiphyte Trichocentrum Undulatum (Orchidaceae): Defining Habitat And The Effects Of Herbivory And Hurricanes At Its Peripheral And Core Range, Haydee Borrero Jan 2022

Population Ecology Of A Caribbean Epiphyte Trichocentrum Undulatum (Orchidaceae): Defining Habitat And The Effects Of Herbivory And Hurricanes At Its Peripheral And Core Range, Haydee Borrero

FIU Electronic Theses and Dissertations

Population ecology studies are central to species conservation. My dissertation focused on the Florida state-listed endangered orchid, Trichocentrum undulatum at its northern-most range in the Everglades National Park (ENP), Florida and multiple populations throughout its core range in Cuba. Through surveying populations of T. undulatum across this range from 2013-2021, I made a new reporting on the occurrence of a specialized insect herbivore, Melanagromyza miamensis in Cuba (Chapter 1). This flower-crippling herbivore was previously known only in the ENP. With this discovery I assess the intensity and impacts of this herbivore, as well as others on T. undulatum across the …

First Contribution To Labiobaetis Novikova & Kluge In Cambodia (Ephemeroptera, Baetidae), With Description Of Two New Species, Thomas Kaltenbach, Jhoana M. Garces, Jean-Luc Gattolliat

Biology Faculty Publications

Material collected in 2018 in Cambodia gives us first insights into the diversity of Labiobaetis Novikova & Kluge, 1987 in this country. No species has been reported so far. We identified two new species using a combination of morphology and genetic distance (COI, Kimura 2-parameter). They are described and illustrated based on their larvae. A key to all Labiobaetis species of continental Southeast Asia is provided. The interspecific K2P distance between the two new species is 20–21%, the intraspecific distance of one of them is 1%. The total number of Labiobaetis species worldwide is augmented to 156.


Artificial Intelligence System For Automatic Imaging, Quantification, And Identification Of Arthropods In Leaf Litter And Pitfall Samples, Pierce Helton, Khoa Luu, Ashley Dowling Jan 2022

Artificial Intelligence System For Automatic Imaging, Quantification, And Identification Of Arthropods In Leaf Litter And Pitfall Samples, Pierce Helton, Khoa Luu, Ashley Dowling

Inquiry: The University of Arkansas Undergraduate Research Journal

It is well known that arthropods are the most diverse and abundant eukaryotic organisms on the planet. Museum and research collections have huge insect accumulations from expeditions conducted over history that contain specimens of both temporal and spatial value, including hundreds of thousands of species. This biodiversity data is inaccessible to the research community, resulting in a vast amount of “dark data”. The primary objective of this study is to develop an artificial intelligence-driven system for specimen identification that greatly minimizes the time and expertise required to identify specimens in atypical environments. Successful development will have profound impacts on both …


Effects Of Drought On Habitat Quality For Native Bees In Residential Gardens Of Claremont, Ca, Max Proctor Jan 2022

Effects Of Drought On Habitat Quality For Native Bees In Residential Gardens Of Claremont, Ca, Max Proctor

CMC Senior Theses

Over 1,500 of the 4000 bee species found in North America inhabit California. Native bees are declining however, largely due to climate change and agricultural intensification. Previous research shows that cities can sustain diverse bee communities, due to the diversity of ornamental flowers. Urban green space represents an opportunity for native bee conservation. Residential gardens provide lots of green space and are urban pollinator hotspots. Managing yards for increased floral resources and nesting habitat can benefit native bee communities. Turfgrass provides few floral or nesting resources and negatively correlates with bee diversity. The 2011-2017 California drought caused many homeowners to …


Systematics And Population Structure Of Amblyomma Maculatum Group Ticks And Rickettsia Parkeri, An Emerging Human Pathogen In Southern Arizona, Usa, Michelle E.J. E Allerdice Dec 2021

Systematics And Population Structure Of Amblyomma Maculatum Group Ticks And Rickettsia Parkeri, An Emerging Human Pathogen In Southern Arizona, Usa, Michelle E.J. E Allerdice

Theses and Dissertations

The recent discovery of Amblyomma maculatum sensu lato (s. l.) ticks in southern Arizona has renewed discussions around species designations for members of the Amblyomma maculatum tick group. Amblyomma maculatum s. l. from Arizona appear to be morphologically intermediate between A. maculatum sensu stricto (s. s.) and A. triste s. s. At present there is no conclusive species designation for the ticks from Arizona. My research focused on analyzing the systematics of both A. maculatum s. l. and Rickettsia parkeri, a common bacterial pathogen transmitted by these ticks.

In the laboratory, A. maculatum s. l. from Arizona and A. maculatum …

Department of Entomology: Dissertations, Theses, and Student Research

Stink bugs (Hemiptera: Heteroptera: Pentatomidae) have gained considerable attention in Nebraska in the last decade due to increasing densities of native stink bug and spread of invasive species in the Midwest. Little is known about stink bug dynamics in Nebraska cropping systems. Based on data from a recent field survey, specimens at the University of Nebraska State Museum and the diagnostic lab of the Entomology Department at the University of Nebraska Lincoln, as well as published literature, we present a checklist of 72 species and subspecies of Pentatomidae (55 Pentatominae, 13 Asopinae, 3 Podopinae and 1 Edessinae) that occur in …


Cognitive Ecology Of Color Vision In Orchid Bees, Andreia Queiroz Santos A Figueiredo Nov 2021

Cognitive Ecology Of Color Vision In Orchid Bees, Andreia Queiroz Santos A Figueiredo

Dissertations

Animals interact with their environment and acquire information from it. Information can be processed by their sensory systems and influence behavior, often mediated through mechanisms of decision-making and learning. Animal pollinators acquire information from flowers and use this information to make decisions about the flowers they visit. My research aimed to understand the role of color vision in a tropical pollinator, the orchid bee Euglossa dilemma. Chapter 1 is a review exploring pollination through the lens of prepared learning. Prepared learning proposes that animals learn some associations better than others due to an evolved match with the environment. I …

Journal of Bioresource Management

Mosquitoes are the most terrifying both for their abundance and for the diseases they transmit. They are vectors of malaria, lymphatic filariasis and arbovirus such as yellow fever, dengue, viral encephalitis and African horse sickness. These characteristics give this fauna prominent importance and health interest. To identify the most widespread mosquito species, we conducted for the first time an inventory in the Aures region more particularly the wilaya of Batna (East of Algeria) from May 2017 to January 2020, we studied their diversity, abundance and distribution. The sampling is done by monthly surveys of the various localities chosen, using the …

Protura (Arthropoda: Hexapoda) In Slovenian Caves, Loris Galli, Franc Janžekovič, Peter Kozel, Tone Novak Mar 2021

Protura (Arthropoda: Hexapoda) In Slovenian Caves, Loris Galli, Franc Janžekovič, Peter Kozel, Tone Novak

International Journal of Speleology

Protura is a small class of Hexapoda, generally poorly known, and rather scarce data on its occurrence in caves are scattered throughout literature on fauna in caves and in some papers on Protura. Although the cave-dwelling fauna is relatively well studied in Slovenia, published records on Protura are rare. In this paper, data on the occurrence and abundance of Protura in Slovenian caves are considered. Various statistical analyses were performed to compare caves with Protura to those without in 60 intensively monitored cavities to detect any differences in the selected environmental conditions. No significant difference was obtained. Samples collected from …


Microhabitat Selection Of A Sicilian Subterranean Woodlouse And Its Implications For Cave Management, Giuseppe Nicolosi, Stefano Mammola, Salvatore Costanzo, Giorgio Sabella, Rosolino Cirrincione, Giovanni Signorello, Marco Isaia Mar 2021

Microhabitat Selection Of A Sicilian Subterranean Woodlouse And Its Implications For Cave Management, Giuseppe Nicolosi, Stefano Mammola, Salvatore Costanzo, Giorgio Sabella, Rosolino Cirrincione, Giovanni Signorello, Marco Isaia

International Journal of Speleology

Human activities in subterranean environments can affect different ecosystem components, including the resident fauna. Subterranean terrestrial invertebrates are particularly sensitive to environmental change, especially microclimatic variations. For instance, microclimate modifications caused by the visitors may directly affect local fauna in caves opened to the public. However, since numerous factors act synergistically in modulating the distribution and abundance of subterranean species, it remains challenging to differentiate the impact of human intervention from that of other factors. Therefore, evidence of the impact of tourism on cave invertebrate fauna remains scarce. Over a year and with approximately two visits a month, we investigated …

Temporal And Spatial Blood Feeding Patterns Of Urban Mosquitoes In The San Juan Metropolitan Area, Puerto Rico, Matthew W. Hopken, Limarie J. Reyes-Torres, Nicole Scavo, Antoinette J. Piaggio, Zaid Abdo, Daniel Taylor, James Pierce, Donald A. Yee

Faculty Publications

Urban ecosystems are a patchwork of habitats that host a broad diversity of animal species. Insects comprise a large portion of urban biodiversity which includes many pest species, including those that transmit pathogens. Mosquitoes (Diptera: Culicidae) inhabit urban environments and rely on sympatric vertebrate species to complete their life cycles, and in this process transmit pathogens to animals and humans. Given that mosquitoes feed upon vertebrates, they can also act as efficient samplers that facilitate detection of vertebrate species that utilize urban ecosystems. In this study, we analyzed DNA extracted from mosquito blood meals collected temporally in multiple neighborhoods of …


Comparison Of Native And Non-Native Predator Consumption Rates And Prey Avoidance Behavior In North America And Europe, Ayse Gül Ünlü, John J. Obrycki, Roman Bucher Oct 2020

Comparison Of Native And Non-Native Predator Consumption Rates And Prey Avoidance Behavior In North America And Europe, Ayse Gül Ünlü, John J. Obrycki, Roman Bucher

Entomology Faculty Publications

Novel predator–prey interactions can contribute to the invasion success of non-native predators. For example, native prey can fail to recognize and avoid non-native predators due to a lack of co-evolutionary history and cue dissimilarity with native predators. This might result in a competitive advantage for non-native predators. Numerous lady beetle species were globally redistributed as biological control agents against aphids, resulting in novel predator–prey interactions. Here, we investigated the strength of avoidance behavior of the pea aphid (Acyrthosiphon pisum) toward chemical cues of native lady beetles and non-native Asian Harmonia axyridis and European Coccinella septempunctata and Hippodamia variegata …

Reinstatement Of Andrena Vernalis Mitchell (Hymenoptera: Andrenidae) From Synonymy With A. Ziziae Robertson, Zachary M. Portman, Ian G. Lane, Gabriella L. Pardee, Daniel P. Cariveau

The Great Lakes Entomologist

Andrena (Micrandrena) ziziae Robertson, 1891 (Andrenidae) is a well-known species found in a variety of habitats in the eastern and central United States and adjacent southern Canada. Andrena (Micrandrena) vernalis Mitchell, 1960 was described from five female specimens in the eastern United States and was synonymized with A. ziziae by Ribble in 1968. Recently collected specimens from throughout Minnesota have revealed that A. ziziae sensu Ribble is actually two species, one of which matches A. vernalis. Here, we reinstate A. vernalis as a valid species and describe the previously unknown male. We provide diagnostic characters …

Ecology Of The Roseau Cane Scale (Nipponaclerda Biwakoensis, Hemiptera: Aclerdidae) In Coastal Louisiana, Leslie Alejandra Aviles Lopez

LSU Master's Theses

Common reed, Phragmites australis, is the dominant plant in the Mississippi River Delta (MRD), Louisiana. Phragmites australis stands reduce soil erosion from wave action, protect the oil infrastructure, and freshwater habitats. In the fall of 2016, widespread reed die-backs in the MRD were associated with outbreaks of an invasive scale Nipponaclerda biwakoensis (Hemiptera: Aclerdidae). Due to the recent detection of the scale, there was limited knowledge of its ecology in the adventive range, and its impacts on P. australis lineages. Therefore, the objectives of my thesis were to determine (1) the host specificity of the N. biwakoensis in important economic …

Anchored hybrid enrichment (AHE) has emerged as a powerful tool for uncovering the evolutionary relationships within many taxonomic groups. AHE probe sets have been developed for a variety of insect groups, though none have yet been shown to be capable of simultaneously resolving deep and very shallow (e.g., intraspecific) divergences. In this study, we present NOC1, a new AHE probe set (730 loci) for Lepidoptera specialized for tiger moths and assess its ability to deliver phylogenetic utility at all taxonomic levels. We test the NOC1 probe set with 142 individuals from 116 species sampled from all the major lineages of …


Impacts Of Commercial Biopesticides On Crapemyrtle Bark Scale (Acanthococcus Lagerstroemiae) And Beneficial Insects, Giovana Matos Franco Apr 2020

Impacts Of Commercial Biopesticides On Crapemyrtle Bark Scale (Acanthococcus Lagerstroemiae) And Beneficial Insects, Giovana Matos Franco

LSU Master's Theses

The crapemyrtle bark scale (CMBS), Acanthococcus lagerstroemiae (Kuwana) (Hemiptera: Eriococcidae), is an important pest of crapemyrtles, Lagerstromia spp. (Myrtales: Lythraceae) since its damage results in an unpleasant aesthetic. Current CMBS management methods depend heavily on pesticides which impact on beneficial insects. Biopesticides show potential for pest control, host specificity, and low impact towards non-target organisms. The objectives of my thesis were to determine (1) if biopesticides are effective against CMBS infestations when applied in different seasons, and (2) their effects towards coccinellids known to attack CMBS.

To test the efficacy of selected biopesticides, treatments were delivered to potted plants or …


Ecological And Economic Benefits And Risks Of Using Botanical Insecticides In Tanzanian Farms, Lilia Garcia Apr 2020

Ecological And Economic Benefits And Risks Of Using Botanical Insecticides In Tanzanian Farms, Lilia Garcia

Independent Study Project (ISP) Collection

Insect damage is a major concern for smallholder farmers in developing countries like Tanzania. Synthetic insecticides can tame infestations, however they can be expensive, inaccessible, and their misuse can threaten farmer health and ecological conditions. Botanical insecticides are cheap alternatives to treat infestations while preserving beneficial insects such as pollinators, predators, and parasitoids. This study assesses how both synthetic and botanical insecticides affect beneficial insects, crop yield and profit/costs. This study finds botanical insecticides slightly less harmful towards non-target insects. Botanical insecticides seldomly improve crop yields but usually result in a higher profit/lower cost. Due to high variation in ecological …
