Population Genetics Of The Western Bean Cutworm (Striacosta Albicosta Smith) Across The United States, Erica Lindroth

Department of Entomology: Dissertations, Theses, and Student Research

The western bean cutworm, Striacosta albicosta (Smith), is a secondary pest of maize (Zea mays L.) and dry beans (Phaseolus vulgaris L.) in the western United States. Recently, this insect has undergone a major territory expansion into the eastern US and has become a pest throughout much of the Corn Belt. This study was instigated to examine the population genetics of this pest to facilitate control and resistance management, as well as to shed light on the current habitat expansion. To this end, western bean cutworm individuals were collected from 28 different locations across the traditional and expanded …

Genetic Variability And Gene Flow Of The Fall Armyworm Spodoptera Frugiperda (J.E. Smith) In The Western Hemisphere And Susceptibility To Insecticides, Difabachew B. Kondidie

Department of Entomology: Dissertations, Theses, and Student Research

The fall armyworm (FAW), Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae), is an economically important pest of maize, sorghum, cotton, and rice in the Western Hemisphere. Previous studies on genetic diversity of FAW focused on identification of the corn and rice host strains; there is limited information about geographic genetic variation. To bridge this gap, I investigated the genetic diversity of FAW using representative samples from the United States, Argentina, Panama, and Puerto Rico with amplified fragment length polymorphism (AFLP). This study also investigated the susceptibility of the Puerto Rico FAW population to ten different insecticides used by Dow AgroSciences …

Larval Taxonomy, Phylogeny And Historical Biogeography Of The Genus Cheumatopsyche (Trichoptera: Hydropsychidae) In North America, Zachary Burington

All Theses

Larvae of the genus Cheumatopsyche (Trichoptera:Hydropsychidae) are a
abundant and probably significant ecological component of freshwater lotic ecosystems
worldwide, with many species inhabiting streams with elevated organic pollution. The
varying tolerance levels among these species necessitate species-level identification for
accurate water-quality assessment. However, past workers have had difficulty separating
the Nearctic species in the larval stage. This research presents progress on the goal
towards identification of larval Cheumatopsyche. Chaetotaxal and cuticular characters are delimited for 7 larval morphotypes, all of which have been putatively associated with
adults. The Nearctic phylogeny of Cheumatopsyche is revised, including 5 species
described after 1987. …

Epigeic Spider (Araneae) Diversity And Habitat Distributions In Kings Mountain National Military Park, South Carolina, Sarah Stellwagen

All Theses

This study examined the epigeic spider fauna in Kings Mountain National Military Park. The aim of this study is to make this information available to park management for use in the preservation of natural resources. Pitfall trapping was conducted monthly for one year in three distinct habitats: riparian, forest, and ridge-top. The study was conducted from August 2009 to July 2010. One hundred twenty samples were collected in each site. Overall, 289 adult spiders comprising 66 species were collected in the riparian habitat, 345 adult comprising 57 species were found in the forest habitat, and 240 adults comprising 47 species …

Chemical Ecology, Population Dynamics And Insecticide Susceptibility Of Lesser Mealworm Alphitobius Diaperinus (Panzer) (Coleoptera: Tenebrionidae), Narinderpal Singh

Graduate Theses and Dissertations

The lesser mealworm, Alphitobius diaperinus (Panzer) (Coleoptera: Tenebrionidae), is a serious, cosmopolitan pest present in poultry production facilities, where it slows down weight gain in chicks, carries disease–causing organisms, and causes damage to poultry insulation. The first study estimated that the lesser mealworm densities in poultry litter applied to pastures were 3.5, 2.2 and 0.4 million larvae, adults and pupae, respectively, per hectare in Savoy, Arkansas. The repercussions of these adult beetles are that they often disperse to and reinfest poultry houses with the potential to vector disease to poultry, and disperse to invade human dwellings resulting in litigation. The …

Brown Marmorated Stink Bug, Erin Petrizzo, Diane G. Alston

All Current Publications

Brown marmorated stink bug (Order Hemiptera: Family Pentatomidae) (BMSB) was accidentally introduced into the eastern U.S. from Asia in the late 1990s. In 2001 it was officially identified in Pennsylvania, and has since spread along the eastern seaboard and westward into the Great Lakes region.

Five New Species Of Anillinus Casey From The Southern Appalachian Mountains And The Piedmont Plateau Of Eastern U.S.A. (Coleoptera: Carabidae: Trechinae: Bembidiini), Igor M. Sokolov

Insecta Mundi

Five new species of anilline ground beetles (Carabidae: Trechinae: Bembidiini) are described from the Appalachian Mountains and Piedmont Plateau of eastern United States. Two species, Anillinus unicoi n. sp. (from the Unicoi Mountains, North Carolina) and A. carltoni n. sp. (from the Great Smoky Mountains, North Carolina/ Tennessee), inhabit the crests of adjacent mountain ranges, and share similarities with A. moseleyae Sokolov and Carlton. These three comprise a high-altitude group of species in the region. The third species A. chilhowee n. sp. Is one of the smallest representatives of the loweae-group of species. It differs from its relatives in characters …

Characterization Of Ips Pini Ipsdienol Dehydrogenase (Idol Dh), Heidi Pak, Claus Tittiger, William Welch

Festival of Communities: UG Symposium (Posters)

Ipsdienol is an important pheromone component for pine engraver beetle, Ips pini. Ipsdienol is a ten carbon monoterpenoid secondary alcohol and ipsdienone is the corresponding ketone. We are characterizing the activity of recombinant IDOL DH produced in Sf9 (insect) cells. The enzyme has a high stereospecificity: (-) ipsdienol was found to be a substrate while (+)-ipsdienol was neither a substrate nor inhibitor. Closely related monoterpenoids, such as nerol, geraniol, and citral, were neither substrates nor inhibitors. Smaller compounds, such as 2-propanol, also failed to act as an inhibitor or substrate. This indicates the binding site of this enzyme is highly …

The Bruchidae (Insecta: Coleoptera) Of La Reserva De La Biósfera Sierra De Huautla, Morelos, Mexico, With Descriptions Of Two New Species And An Annotated Checklist, Jesús Romero Nápoles, Richard L. Westcott

Insecta Mundi

From 1995 to 2004 collections for Bruchidae (Coleoptera) were made in La Reserva de la Biósfera Sierra de Huautla, Morelos, Mexico. Specimens were reared from mature seedpods, but also collected by net, malaise trap, and light trap. In total 72 species in 13 genera of Bruchidae were recovered. Of those two new species are here described: Amblycerus montalvoi Romero and Acanthoscelides camerinoi Romero. We record 27 host plants for the bruchids found in the study area.

New Collections And Records For Earwigflies And Scorpionflies (Mecoptera: Meropeidae And Panorpidae) In Florida, Louis A. Somma

Rediscovery Of Cicindela Scabrosa Floridana Cartwright (Coleoptera: Cicindelidae) And Its Elevation To Species Level, David Brzoska, C. Barry Knisley, Jeffrey Slotten

Insecta Mundi

First discovered in 1934 and described as a variety of Cicindela abdominalis Fabricius (Coleoptera: Cicindelidae), the form floridana, to our knowledge, has not been recollected until we discovered it in 2007, south of the presumed type locality. From our examination of the type specimen, eight paratypes and 40 specimens from the new locality and additional study, we reinterpreted its status to be a full species. This interpretation is based on distinctive and consistent differences from the closely related Cicindelidia scabrosa (Schaupp). These differences include morphology (maculation, color and elytral microsculpture), distribution, habitat, and seasonality. We present here a more …

A Second Species Of Lucanobium Howden And Lawrence From South America (Coleoptera: Lucanidae: Aesalinae), M. J. Paulsen

Insecta Mundi

The monotypic aesaline genus Lucanobium Howden and Lawrence (Coleoptera: Lucanidae) was previously known only from Venezuela. A second species is here described as new from French Guiana, extending the range of the genus approximately 1800 km to the southeast. The generic description of Lucanobium is updated with respect to the discovery of a second species.
