Morphological Characterization And Molecular Mediated Genetic Variation Of Thief Ant (Solenopsis Molesta Say, Hymenoptera: Formicidae), Ralph B. Narain

Department of Entomology: Dissertations, Theses, and Student Research

The thief ant, Solenopsis molesta (Say), a common nuisance ant species found throughout the United States is genetically related to other stinging ants. This research was undertaken to estimate genetic variation utilizing mitochondrial DNA sequences of cytochrome oxidase I in thief ant populations from various geographic locations. Thief ants were collected from nine states, identified to species using morphologic characteristics from available keys. DNA extractions were completed with Qiagen’s Gentra PUREGENE® DNA Isolation Kit using their solid tissue protocol. PCR reactions were run on the extracted DNA using primers Lep-F1 (forward) and Lep-R1 (reverse). The resulting DNA products were concentrated …

An Investigation Of Wild Bee Diversity And Abundance In Plots Managed By The Nature Conservancy In South-Central Nebraska And Of Beneficial Arthropods Associated With Native Nebraska Flora, Dori Ann Porter

Department of Entomology: Dissertations, Theses, and Student Research

Insect pollination is an essential ecosystem service, and bees are the principal pollinators of wild and cultivated plants. Habitat management and enhancement are a proven way to encourage wild bee populations, providing them with food and nesting resources. I examined bee diversity and abundance in plots managed by The Nature Conservancy near Wood River, NE. The plots were seeded with 2 seed mixes at 2 seeding rates: high diversity mix at the recommended rate, high diversity mix double the recommended rate, Natural Resources Conservation Service (NRCS) conservation planting (CP) 25 mix at one-half the recommended rate, and NRCS CP25 mix …

Insect Diversity And Pest Status On Switchgrass Grown For Biofuel In South Carolina, Claudia Holguin

All Theses

Switchgrass (Panicum virgatum L.) has tremendous potential as a biomass and stock crop for cellulosic ethanol production or combustion as a solid fuel. The first goal of this study was to assess diversity of insects in a perennial switchgrass crop in South Carolina. A three-year study was conducted to sample insects using pitfall traps and sweep nets at the Pee Dee Research and Education Center in Florence, SC, from 2007-2009. Collected specimens were identified to family and classified by trophic groups, and predominant species were identified. The diversity and density of weeds in the field during the establishment year (2007) …

A comprehensive revision of the Subfamily Parandrinae (Coleoptera, Cerambycidae) from the Hawaiian, Australasian, Oriental, and Japanese regions is presented. Seven (7) new genera are described: Komiyandra, Melanesiandra, Papuandra, Storeyandra, Hawaiiandra, Caledonandra, and Malukandra. All known, indigenous species from these regions are assigned to new genera resulting in the following new combinations: Komiyandra janus (Bates, 1875), K. shibatai (Hayashi, 1963), K. formosana (Miwa and Mitono, 1939), K. lanyuana (Hayashi, 1981), Melanesiandra striatifrons (Fairmaire, 1879), M. solomonensis (Arigony, 1983), Caledonandra austrocaledonica (Montrouzier, 1861), C. passandroides (Thomson, 1867), Hawaiiandra puncticeps (Sharp, 1878), Malukandra heterostyla (Lameere, 1902), Storeyandra frenchi (Blackburn, 1895), and Papuandra araucariae …

A Taxonomic Review Of The Neotropical Genus Coprophanaeus Olsoufieff, 1924 (Coleoptera: Scarabaeidae, Scarabaeinae, W. D. Edmonds, J. Zidek

Insecta Mundi

The Neotropical genus Coprophanaeus Olsoufieff (1924), as classified here, comprises 38 species distributed among three subgenera (Megaphanaeus Olsoufieff, Metallophanaeus Olsoufieff, and Coprophanaeus s. str. ) and eight species groups. Keys presented help to identify supraspecific and species taxa, all of which are illustrated and diagnosed. Lectotypes are designated for Phanaeus ignecinctus Felsche and Phanaeus ohausi Felsche. Coprophanaeus corythus (Harold), formerly regarded as a subspecies of C. telamon (Erichson), assumes species status. Coprophanaeus magnoi Arnaud, described as a subspecies of C. milon (Blanchard), is raised to species status. New taxonomic interpretations result in 10 new subjective synonymies (junior synonym listed …

Carrion Beetles Of The Blackwater Ecologic Preserve: Community Structure Seasonal Patterns And Habitat Use, Amy L. Simons

Biological Sciences Theses & Dissertations

Carrion beetles (Silphidae) are important in the decomposition of carcasses in ecosystems. Two subfamilies, Nicrophorinae and Silphinae, differ in reproductive behaviors. The Nicrophinae, burying beetles, bury small carcasses to serve as food for the adults and their offspring. The Silphinae oviposit near larger carcasses. There is intense competition among all carrion beetles and other carrion feeders for carcasses, and beetle species have evolved seasonal activity patterns that minimize competition, such as when they are active and when they reproduce. Northern Silphidae communities are more diverse than southern communities, probably due to increased competition for carrion in the south.

The Mosquito (Diptera: Culicidae) Fauna Of The Blackwater Ecological Preserve: Effects Of Prescribed Burns And Habitat Type On Mosquito Abundance And Distribution, Norman A. Grefe Lll

Biological Sciences Theses & Dissertations

While mosquitoes (Diptera: Culicidae) are among the most studied of insect groups, much remains unknown about their distribution and response to environmental impacts such as prescribed burns. Blackwater Ecological Preserve, located near Zuni, Virginia, is a relict long leaf pine barren, parts of which undergo periodic prescribed burns to maintain and restore this fire-dependent ecosystem. To assess the impact of prescribed burns on mosquito activity and to determine associations between seasonal patterns of adult mosquito activity and habitat type, CDC light traps baited with dry ice were set (rom late April through October at Blackwater Ecological Preserve during the 2005 …

Comparative Mitogenomics Of Braconidae (Insecta: Hymenoptera) And The Phylogenetic Utility Of Mitochondrial Genomes With Special Reference To Holometabolous Insects, Shu-Jun Wei, Min Shi, Michael J. Sharkey, Cornelis Van Achterberg, Xue-Xin Chen

Entomology Faculty Publications

BACKGROUND: Animal mitochondrial genomes are potential models for molecular evolution and markers for phylogenetic and population studies. Previous research has shown interesting features in hymenopteran mitochondrial genomes. Here, we conducted a comparative study of mitochondrial genomes of the family Braconidae, one of the largest families of Hymenoptera, and assessed the utility of mitochondrial genomic data for phylogenetic inference at three different hierarchical levels, i.e., Braconidae, Hymenoptera, and Holometabola.

RESULTS: Seven mitochondrial genomes from seven subfamilies of Braconidae were sequenced. Three of the four sequenced A+T-rich regions are shown to be inverted. Furthermore, all species showed reversal of strand asymmetry, suggesting …

Three New Species Of Paragnorimus Becker From Central America (Coleoptera: Scarabaeidae: Cetoniinae: Trichiini) With A Redefinition Of The Genus, Andrew B. T. Smith

Insecta Mundi

Three new species of Paragnorimus Becker are described: Paragnorimus atratus n. sp. from Guatemala, P. hondurensis n. sp. from Honduras and Nicaragua, and P. howdeni n. sp. from Guatemala. Based on the overlapping characters of these new species, the genus Peltotrichius Howden is placed in synonymy with Paragnorimus. Paragnorimus is given a broader definition to encompass the new species and the two species formerly placed in the genus Peltotrichius.

Taxonomy, Biogeography And Pest Status Of Marmara Sp. In Northern Mexico And California Citrus Production, Paul Semet

Master's Theses

A novel lepidopteran sex pheromone lure which was thought to be species-specific to the citrus pest Marmara gulosa (Lepidoptera: Gracillariidae) Guillén (McElfresh et al. 2009) has attracted male moths exhibiting two distinct morphologies. The morphological features examined were the sclerotized parts that make up the male genitalia; which include the valvular lobes, costal lobes, cucullar lobes, and the aedeagus. The sclerotized parts were methodically dissected and mounted on microscope slides. Digital images captured of the slide-mounted specimens proved to be inconsistent with the illustrations provided in the original Marmara gulosa species description (Guillén et al. 2001).

The morphologies of all …
