Repair Of The Proboscis Of Brush-Footed Butterflies (Lepidoptera: Nymphalidae), Suellen Pometto
Repair Of The Proboscis Of Brush-Footed Butterflies (Lepidoptera: Nymphalidae), Suellen Pometto
All Theses
A key feature of the order Lepidoptera is the coilable proboscis, present in over 99% of lepidopteran species. The proboscis is used to obtain liquid nutrition, usually floral nectar. The proboscis is assembled from two elongate galeae immediately after emergence of the adult from the pupa. What happens if the galeae become separated? I studied the process of repair of the proboscis, behaviorally and functionally, at the organismal level. My research questions were as follows: 1) is the proboscis capable of repair, 2) is saliva necessary to proboscis repair, and 3) is the repaired proboscis able to acquire fluids? Test …
Use Of Macroinvertebrates In Bioassessment Of Land Use And Water Quality In Northern Mongolia, Oyunchuluun Yadamsuren
Use Of Macroinvertebrates In Bioassessment Of Land Use And Water Quality In Northern Mongolia, Oyunchuluun Yadamsuren
All Dissertations
Land-use practices in Mongolia lead to habitat degradation and consequently affect the structure and function of biological communities. There is no accepted bioassessment technique for determining the ecological consequences of habitat degradation on biological communities and water quality in Mongolia, such that a monitoring and management program suitable for Mongolia is sorely needed. Both a trait-based approach and the North American Rapid Bioassessment Protocol (RBP) metrics were tested with macroinvertebrates to determine the performance and applicability of these approaches for predicting general ecological responses of freshwater and terrestrial communities to habitat variation due to overgrazing and mining in northern Mongolian …

Behavior And Control Of The Bed Bug, Cimex Lectularius L. (Hemiptera: Cimicidae), Margaret Lehnert
All Dissertations
The recent resurgence of bed bugs has led to an explosion of bed bug research influenced by the applied needs of pest management professionals. I assessed the needs of pest management professionals who deal with bed bugs in South Carolina. Bed bugs were reported in 28 of 46 counties in South Carolina. Previous samples of bed bug populations have displayed a 1:1 sex-ratio suggesting females do not use aggregations and harborages to hide from males and traumatic insemination, which can be harmful to females. Aggregations are biased in composition, suggesting that females are able to hide from males within harborages. …
Temporal Food Preference And Effectiveness Of Selected Bait Products Against Pachycondyla Chinensis (Emery) (Hymenoptera: Formicidae), Ying Mo
All Theses
Pachycondyla chinensis (Emery), commonly known as the Asian needle ant is a well-established invasive species in urban and woodland areas in South Carolina. Foraging ants are found around or under places such as sidewalks, flowerbeds, mulch, tree bases, stones, and logs where human outdoor activity takes place in urbanized area. It is not an aggressive ant, but it has a powerful sting that causes severe allergic reactions in some people. It also has a negative impact on native ant species in forest environments. Food preference was studied, followed by an evaluation of selected bait products against P. chinensis.
Protein, carbohydrate, …

Forest Fragments As Barriers To Fruit Fly Dispersal: Anastrepha (Diptera: Tephritidae) Populations In Orchards And Adjacent Forest Fragments In Puerto Rico, David A. Jenkins, Paul E. Kendra, Skip Van Bloem, Stefanie Whitmire, Russ Mizell Iii, Ricardo Goenaga
Publications
McPhail-type traps baited with ammonium acetate and putrescine were used to monitor populations of Anastrepha obliqua (Macquart) and Anastrepha suspensa(Loew) in two orchards with hosts of these flies (mango, Mangifera indica L., and carambola, Averrhoa carambola L.), as well as in forest fragments bordering these orchards. Contour maps were constructed to measure population distributions in and around orchards. Our results indicate that Anastrephapopulations are focused around host fruit in both space and time, that traps do not draw fruit flies away from hosts, even when placed within 15 m of the host, and that lures continue to function …
Treatment Thresholds For Bollworm (Helicoverpa Zea) In Dual-Gene Bt Cotton, Kristen Carter
Treatment Thresholds For Bollworm (Helicoverpa Zea) In Dual-Gene Bt Cotton, Kristen Carter
All Theses
Dual-gene Bt cotton has reduced the need for insecticide treatments for bollworm, Helicoverpa zea (Boddie), compared with original single-gene Bt technology. Bollgard II¨ (Monsanto, St. Louis, MO) and WideStrike¨ (Dow AgroSciences, Indianapolis, IN), both produce the Cry1Ac protein and a second protein, Cry2Ab or Cry1F, respectively. These dual-gene Bt cottons provide enhanced control of lepidopteran pests, but remain less than 100% effective against bollworm, particularly when population pressure is high. Current recommended treatment thresholds for bollworm on cotton in South Carolina are as follows: treat with insecticides when three or more large larvae are found per 100 plants or when …

Trapping And Control Of The Small Hive Beetle, Aethina Tumida, An Invasive Parasite Of Honey Bees, Apis Mellifera, Shannon Peterson
All Theses
The small hive beetle, Aethina tumida Murray (Coleoptera: Nitidulidae), is one of the most recent honey bee pests of economic importance, especially in the southeastern United States. Various in-hive traps have been developed to attempt to control the populations of this invasive pest within honey bee colonies. The first year of my research focused on comparing the effectiveness of three commercially available traps for removing small hive beetles. Thirty-two colonies were established with 0.9-kg package bees with a queen in four apiaries. Eight colonies were placed in each apiary, each colony randomly receiving one of four treatments: the three-chambered Hood …
Chromosomal Patterns In Populations Of The Black Fly Simulium Fibrinflatum Twinn (Diptera: Simuliidae), Kyle Parks
Chromosomal Patterns In Populations Of The Black Fly Simulium Fibrinflatum Twinn (Diptera: Simuliidae), Kyle Parks
All Theses
Cryptic species are an important component of biodiversity, although most cryptic species have yet to be discovered. Cytogenetic studies of polytene chromosomes offer a unique level of resolution for detecting cryptic species in the family Simuliidae. Simulium fibrinflatum is a black fly morphospecies that is suspected to contain cryptic species because of its broad geographic range and variable pupal gill structure. Populations of Simulium fibrinflatum from the Saugahatchee River, AL; Anthony Shoals, GA; LaHave River, Nova Scotia; Westfield River, MA; Chauga River, SC; and Enoree River, SC, were sampled and cytogenetically analyzed to test for the presence of cryptic species. …

Fluid Uptake By The Lepidopteran Proboscis In Relation To Structure, Karena Kwauk
All Theses
Three species of butterflies--eastern tiger swallowtail (Papilio glaucus L.), monarch (Danaus plexippus L.), and painted lady (Vanessa cardui L.)--were used to investigate the effect that exposing multiple regions of the proboscis to fluid has on feeding rate. Although the lepidopteran proboscis historically has been considered a sealed tube with a specialized region near the tip for fluid uptake, droplets of 1% sucrose solution were shown to enter multiple locations along the proboscis. Feeding experiments were conducted comparing fluid uptake rates of butterflies with their proboscises either fully or partially submerged in 1% or 15% sucrose solutions. Only one significant relationship …

Ecology And Phylogeny Of The Biting-Midge Genus Culicoides (Diptera: Ceratopogonidae), Dustin Swanson
All Dissertations
Flies of the genus Culicoides are small, biting midges in the family Ceratopogonidae. These flies are of medical, veterinary, and economic importance because their blood-feeding behavior can cause stress to hosts and transmit disease agents. Despite the importance of these flies, little is known about their biology, especially the ecology of the immature stages and the phylogenetic relationships among taxa. The objectives of my study were to address these two areas of Culicoides biology.
Larval Culicoides were collected from aquatic habitats in four ecoregions of South Carolina, USA. Eleven ecological variables were recorded for each sample. Larvae were identified by …
The Diets Of Larval And Juvenile Pallid Sturgeon And Shovelnose Sturgeon (Scaphirhynchus Spp.) In The Lower Mississippi River, Audrey Harrison
The Diets Of Larval And Juvenile Pallid Sturgeon And Shovelnose Sturgeon (Scaphirhynchus Spp.) In The Lower Mississippi River, Audrey Harrison
All Theses
Although North American sturgeon have been the focus of extensive research in the last several decades, more research is essential to ensure their conservation. The free-flowing Lower Mississippi River (LMR) is occupied by two sympatric sturgeon, pallid [ Scaphirhynchus albus (Forbes & Richardson)] and shovelnose sturgeon [Scaphirhynchus platorynchus (Rafinesque)]. These species are considered 'endangered' and 'threatened,' respectively. Recent studies have documented the life history of adult sturgeon in the Mississippi River, but studies focusing on young-of-year and juveniles are limited because young fish are difficult to collect and identifications are problematic. Spawning sites in the LMR are unknown and though …

Zoos As Experiment Environments: Biology Of Larval And Adult Mosquitoes (Diptera: Culicidae), Holly Tuten
All Dissertations
Zoos are a unique environment where humans and animals are in close daily contact, potential mosquito habitats exist, exotic plants and animals are introduced regularly, and wild animals roam. Studies of mosquito behaviors in zoos will lead to a better understanding, both within and outside zoos, of disease transmission routes and mosquito biology. To investigate whether the unique assemblage of habitats in zoos affects mosquito behavior, I sampled larvae and adults in the Greenville Zoo and the Riverbanks Zoo, South Carolina, USA, from March 2008 to January 2011. The objectives of my study were to investigate mosquito oviposition behavior, blood-host …
Larval Taxonomy, Phylogeny And Historical Biogeography Of The Genus Cheumatopsyche (Trichoptera: Hydropsychidae) In North America, Zachary Burington
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. …

Population Dynamics And Parasitism Of Brassica Insect Pests In Zimbabwe With Emphasis On The Diamondback Moth, Plutella Xylostella (L.) (Lepidoptera: Plutellidae), Walter Manyangarirwa
All Dissertations
The diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), is a major insect pest of brassicas in Zimbabwe. Field surveys were conducted to assess brassica pest management practices at large scale farms (≈2.0-10.0 ha) and smallholder farms (<2.0 ha). Insecticides used on large scale farms include λ-cyhalothrin, fenvalerate, dimethoate, malathion, diazinon, dichlorvos, kelthane and lufenuron. Smallholder farmers predominantly used dimethoate, malathion, diazinon, methamidophos, dichlorvos, fenvalerate, carbaryl and methomyl. Six out of seven smallholder farmer clusters were ranked into an Intermediate Category between Integrated Pest Management (IPM) practices and Conventional Insecticide use. Smallholder farmers in the Chinamhora area were ranked into a Conventional Insecticide use category. Five out of seven large scale farms were ranked into a Conventional Insecticide use category while two of the seven farms were ranked into an Intermediate Category.
Diamondback moth larval incidence was high in the hot-dry season in October and November of both 2007 and 2008 and reached a density of 15.58 larvae per plant at Nyanga in November 2008. The major larval endoparasitoid was Cotesia plutellae (Hymenoptera: Braconidae) and parasitism reached 95.51% at a host density of 2.83 larvae per plant at Harem in early summer (October and November) …
Reproductive Strategies And Colony Relatedness In The Invasive Ponerine Ant Pachycondyla Chinensis (Emery), Andrew Tebeau
Reproductive Strategies And Colony Relatedness In The Invasive Ponerine Ant Pachycondyla Chinensis (Emery), Andrew Tebeau
All Theses
Pachycondyla chinensis (Emery) (Formicidae: Ponerinae), is an ancestral ant introduced from Asia. It is considered a pest species of medical and ecological concern. Since its initial 1932 documentation occurring in three Southeastern U.S. states at relatively low frequencies, the invasion of P. chinensis has spread to at least three additional states in discontinuously widespread populations that are locally abundant. Little is known about P. chinensis population structure and reproduction, and an investigation into these strategies offers insight into the means by which this pest species proliferates, and ultimately, can assist in the design of management strategies. The objectives of this …

Managing Linepithema Humile (Mayr), The Argentine Ant, In South Carolina State Park Campgrounds, Brittany Ellis
All Theses
Linepithema humile (Mayr), the Argentine ant, is known as a pest in many urban areas of the southeastern United States. In the Piedmont region of South Carolina, there is a documented problem with L. humile invading the campsites of state park campgrounds. While some parks have tried to implement proactive control programs, the most widely used tactic is spraying insecticides when L. humile populations become intolerable to visitors. Although park personnel are treating problem areas with liquid insecticide, park visitors also treat their campsites with insecticidal products, as well as products not labeled for ant control.
Surveys in 2008 showed …

Comparative Morphological And Functional Analysis Of Wing Coupling And Related Structures In Caddisflies (Insecta: Trichoptera), Ian Stocks
All Dissertations
Several orders of morphologically four-winged insects have evolved mechanisms that enforce a union between the mesothoracic and metathoracic wings (forewings and hindwings) during the wing beat cycle. Such mechanisms result in a morphologically tetrapterous insect flying as if it were functionally dipterous, and these mechanisms have been described for several insect orders. The caddisfly suborders Annulipalpia and Integripalpia (Trichoptera) have each evolved wing coupling apparati. At least three systems have evolved within the suborder Annulipalpia (Polycentropodidae; Hydropsychidae: Hydropsychinae, Macronematinae), and within Integripalpia the evolution of wing coupling mechanisms is diverse to the point that it defies simple enumeration into discrete …

Trapping Small Hive Beetles, Aethina Tumida Murray, Inside Honey Bee Colonies, Maxcy Nolan Iv
All Theses
The small hive beetle, Aethina tumida Murray, (Coleoptera: Nitidulidae) is an economically important honey bee pest, particularly in the southeastern United States. One method of controlling this pest is the use of an in-hive trap. Many different attractants have been developed and are used in such traps. Part one of my thesis involved testing a new attractant, a pollen substitute inoculated with the yeast Kodamaea ohmeri (NRRL Y-30722). Thirty-two test colonies were established with 0.9-kg (2-lb) packages of bees with queens. Eight colonies were placed in each apiary, and colonies received one of three treatments: 1) yeast-based attractant 2) apple …
