Induced Resistance Studied In Maize With The Fall Armyworm, Spodoptera Frugiperda (J.E. Smith) (Lepidoptera: Noctuidae) And The Chemical Inducer Actigard, Stephen D. Danielson

Department of Entomology: Faculty Publications

Induced resistance has been defined as the "qualitative or quantitative enhancement of a plant's defense mechanisms against pests in response to extrinsic physical or chemical stimuli." (Kogan and Paxton, 1983). Physical stimuli can include infection by a pathogenic organism (Jorgensen et al, 1996; Morris et al, 1998) and feeding by insects (Felton and Eichenseer, 1999). Chemical stimuli include such organic compounds as salicylic acid (Hammerschmidt and Smith-Becker, 1999), jasmonic acid (Staswick and Lehman, 1999), and the commercially available Actigard® 50WG (Tally et al., 1999) (Syngenta Crop Protection, P.O.

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. …

Species Diversity And Seasonal Abundance Of Scarabaeoidea At Four Locations In South Carolina, Kevin Hinson

All Theses

ABSTRACT
Using light, flight-intercept, and pitfall traps, 74, 327 specimens of Scarabaeoidea were captured at four golf courses in South Carolina during 2009-2010. Aphodiinae were identified only to the subfamily level and totaled 57,502 specimens. 16,825 specimens in 47 genera and 104 species in the families Ceratocanthidae, Geotrupidae, Hybosoridae, Lucanidae, Passalidae, Scarabaeidae (excluding Aphodiinae), and Trogidae were identified based on morphological characteristics. Similar to other southeastern studies focusing on phytophagous scarabs, the most abundant species consisted of Dyscinetus morator (Fabricius), Euetheola humilis (Burmeister), Cyclocephala lurida Bland, and Hybosorus illigeri Reiche. The most speciose genus captured was Phyllophaga Harris, totaling 22 …

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 …

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 …

Investigating Mechanisms Of Co-Occurrence Between Two Similar Specis Of Predaceous Diving Beetles (Coleoptera: Dytiscidae) In Temporary Aquatic Habitats, Kristopher Alexander Pitcher

Master's Theses

Predaceous diving beetles (Coleoptera: Dytiscidae) are a model group of organisms for testing coexistence and exclusion mechanisms because numerous species of the family interact in isolated, aquatic habitats, and are ubiquitous throughout landscapes. Two morphologically similar species, laccophilus fasciatus rufus and Laccophilus proximus, co-occur in numerous habitats in South Mississippi, but are hypothesized to have strong interspecific interactions. I investigated several possible mechanisms that may promote such coexistence, including segregation in habitat domain, differences in behavior, and differences in dispersal that may allow co-occurrence between these two species of beetle. Habitat domain and behaviors such as activity and prey consumption …

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 …

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 …
