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 …

The Role Of Larval Fat Cells In Starvation Resistance And Reproduction In Adult Drosophila Melanogaster, Jerell Roland Aguila

UNLV Theses, Dissertations, Professional Papers, and Capstones

The intricate life cycle of holometabolous insects includes well-defined larval and adult stages associated with feeding and non-feeding periods. The larval stage is distinguished by prevalent feeding and is necessary for supporting the animal as it quickly grows. The larval stage also serves as the period for the animal to obtain adequate energy stores, primarily in the larval fat body, to fuel the animal through the non-feeding pupal and immature adult stages. Acquiring sufficient energy stores is paramount for the success of the adult animal. In fact, certain insects, such as silkworms and mayflies, do not feed as adults and …

Arid Climate Decomposition And Decay: A Taphonomic Study Using Swine, James William Munkres

UNLV Theses, Dissertations, Professional Papers, and Capstones

The present project analyzes the taphonomic processes and variables involved in the decomposition and desiccation of animal remains in an arid/hyper-arid environment. The study and the derived data will assist in determining postmortem intervals for remains in modern contexts, inform judgments made regarding mortuary habits and techniques in archaeological contexts, and will improve our knowledge regarding taphonomic processes. Manner of deposition, the depositional surface/medium and arid-climate specific variables (temperature, water, insect activity, weathering, pH levels, and soil characteristics) were examined in this study. Reported observations are limited to the first ten months following death from early December through early October …

Seed Predation On Slickspot Peppergrass By The Owyhee Harvester Ant, Joshua P. White

Boise State University Theses and Dissertations

1. (1) Seed predation can significantly restrict the reproductive output and individual fitness of plants, particular those plants that are rare or endangered. In some cases the total seed loss can reach 100%. Owyhee harvester ants, Pogonomyrmex salinus, actively remove the fruits and seeds of slickspot peppergrass, Lepidium papilliferum, a rare mustard endemic to southwest Idaho.
2. (2) Several experiments were conducted to quantify seed predation on L. papilliferum located within the foraging distance of P. salinus. Individuals exposed to harvester ants experienced a direct loss of fruits and seeds ( > 40%), whereas plants shielded from ants suffered almost …

On-Plant Survival And Inheritance Of Resistance To Cry1ab Toxin From Bacillus Thuringiensis In A Field-Derived Strain Of European Corn Borer, Ostrinia Nubilalis, Andre L. B. Crespo, Terence A. Spencer, Analiza P. Alves, Richard L. Hellmich, Erin E. Blankenship, Leonardo C. Magalhães, Blair D. Siegfried

Department of Entomology: Faculty Publications

BACKGROUND: The high dose plus refuge is one of the major components of the resistance management plan mandated for transgenic corn expressing Cry toxins from Bacillus thuringiensis Berliner (Bt) that targets the European corn borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae). This strategy was based on assumptions such as functional recessive inheritance, which has not been previously tested for O. nubilalis. The authors used a field-derived resistant strain of O. nubilalis to define the nature of resistance to Cry1Ab toxin by examining the inheritance and on-plant survival of susceptible and resistant insects and their F1 progeny.

The Ants Of South Carolina, Timothy Davis

All Dissertations

The ants of South Carolina were surveyed in the literature, museum, and field collections using pitfall traps. M. R. Smith was the last to survey ants in South Carolina on a statewide basis and published his list in 1934. VanPelt and Gentry conducted a survey of ants at the Savanna River Plant in the 1970's. This is the first update on the ants of South Carolina since that time.
A preliminary list of ants known to occur in South Carolina has been compiled. Ants were recently sampled on a statewide basis using pitfall traps. Two hundred and forty-three (243) transects …

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 …

Variability In Pheromone Communication Among Different Haplotype Populations Of Busseola Fusca, A. E. Félix, G. Genestier, C. Malosse, P. A. Calatayud, B. Le Rü, J. F. Silvain, B. Frérot

All Peer-Reviewed Publications

The relationship between pheromone composition and mitochondrial haplotype clades was investigated by coupling DNA analyses with pheromone identification and male mate searching behavior among different geographic populations of Busseola fusca. The within-population variations in pheromone blend were as great as those observed between geographic populations, suggesting that the female sex pheromone blend was not the basis of reproductive isolation between the geographic clades. Furthermore, while data from wind tunnel experiments demonstrated that most of the tested males were sensitive to small variations in pheromone mixture, there was considerable within-population variability in the observed response. The study identified a new pheromone …

New Country Records Of Caddisflies (Insecta: Trichoptera) From Vietnam, Brian Armitage, Tatiana Arefina-Armitage

Insecta Mundi

Identification of caddisfly specimens from Vietnam collected by scientific field staff of the Royal Ontario Museum and the American Museum of Natural History revealed 19 new country records. All but one species were reported from other Oriental region countries, particularly Thailand and Indonesia. However, Goera kawamotonis Kobayashi 1987 was only known from the East Palaearctic region (Japan and Russian Far East). The total number of species now recorded from Vietnam is 400.

The Beetles Of Barbados, West Indies (Insecta: Coleoptera): Diversity, Distribution And Faunal Structure, Stewart Peck

Insecta Mundi

The beetle fauna of the island of Barbados is summarized. It is now known to contain 202 genera, and 254 species (in 40 families), of which 232 are named at the species level. Undoubtedly, the actual numbers of species on Barbados are much higher than now known. Nine species are possibly endemic to the island, 15 have been intentionally introduced, and 51 have probably been accidentally introduced through human activity. The remaining 157 named species may occur naturally as a result of natural over-water dispersal processes. These species mostly have a wide distribution in the Antilles and Latin America. The …

Distribution Extensions Of The Milliped Families Conotylidae And Rhiscosomididae (Diplopoda: Chordeumatida) Into Northern Coastal British Columbia And Southern Alaska, Rowland Shelley, Michael Medrano, William Shear, Kristiina Ovaska, Ken J. White, Erin Havard

Insecta Mundi

Two samples of the chordeumatidan family Rhiscosomididae (Rhiscosomides mineri Silvestri, 1909) and 35 of the Conotylidae establish these taxa in the Alexander Archipelago and continental parts of the Alaskan Panhandle, USA, and northern coastal British Columbia (BC), Canada. Rhiscosomides mineri is also recorded from southwestern BC and, for the first time, from Washington State, USA. Two conotylids were recovered, a juvenile male of ?Bollmanella Chamberlin, 1941, and 3 males and 33 females of a possibly parthenogenetic form of Taiyutyla Chamberlin, 1952, conforming generally to T. shawi and T. lupus, both by Shear, 2004, on Vancouver Island. Diplopoda are …

Ecological Traits Of A New Aphid Parasitoid, Endaphis Fugitiva (Diptera: Cecidomyiidae), And Its Potential For Biological Control Of The Banana Aphid, Pentalonia Nigronervosa (Hemiptera: Aphididae), Frédéric B. Muratori, Raymond J. Gagne, Rusell H. Messing

USDA Systematic Entomology Laboratory

Most parasitoids of aphids are small wasps belonging to the families Braconidae or Aphelinidae. However, some dipteran parasitoids are also known to use aphids as hosts. We describe and give life-history information on a new species of aphid parasitoid, Endaphis fugitiva Gagné and Muratori, found to parasitize the banana aphid, Pentalonia nigronervosa Coquerel, the vector of banana bunchy top virus. Field and laboratory observations show that fly eggs are laid on the leaves near an aphid colony, the newly hatched fly larvae search for hosts while crawling on the leaf, and then penetrate the aphid between the legs and thorax. …

Apostasimerini (Coleoptera: Curculionidae: Baridinae). Rectification Of Authorship, Year Of Publication, Rank, And Taxa Included Full Access, Jens Prena

USDA Systematic Entomology Laboratory

Kuschel (1952) transferred Erirhinoides mourei Bondar, 1943 to Apostasimerus Schönherr, 1844 and indicated a possible synonymy with A. serrirostris Boheman, 1844. The suggestion was based on work on numerous collections, not on direct comparison of specimens. Recently I had the opportunity to study the Gregorio Bondar Collection at the American Museum of Natural History, New York and compared the lectotype of A. mourei (designated by Vaurie 1953) with images of the holotype of A. serrirostris and with specimens of the National Museum of Natural History, Washington, D.C. Apostasimerus mourei (Bondar) is here regarded as a new junior subjective synonym of …

Bromeliads As A Breeding Site For The Dengue Vector Aedes Aegypti, Eva B. Shultis

Independent Study Project (ISP) Collection

Dengue Fever is a major public health concern in tropical and subtropical climates worldwide, including the city of Cairns, Australia, which is currently suffering a severe outbreak. The most important vector of the Dengue virus is the predominantly urban mosquito Aedes aegypti (L.), which lays its eggs in both artificial and natural containers, including the ornamental bromeliad plants found in many household gardens. The ability of larvae to develop to adulthood inside bromeliads has become controversial, however, and bromeliad enthusiasts frequently refuse to have their plants treated with insecticide. The aim of this study was to determine the conditions under …

Dothistroma Needle Blight, Erin Frank, Kent Evans

All Current Publications

A landscape design should meet the needs of the people who will use and maintain the area while incorporating the site’s existing environmental conditions into the design. Water is a limiting resource in Utah, so designing the landscape to efficiently use water is important. Conserving water in the landscape can be accomplished by selecting low water use plants, designing and scheduling irrigation systems efficiently, grouping plants according to their water requirements, and using hardscaping materials (patios, stone paths, decks, etc.) appropriately to reduce the area requiring irrigation.

Efficacy Of Botanical And Mineral Oils On Willamette Mite (Acari: Tetranychidae), Elizabeth Ruby Begonia Church

Master's Theses

Willamette mite (WM), Eotetranychus willamettei, is a major pest throughout most winegrape regions in coastal California and Oregon. These mites puncture leaf tissue with their chelicerae and cause loss of photosynthetically active area. Chemical control treatments on grape include nearly ten registered synthetic miticides, plus soaps and oils. Oils can be petroleum based (mineral oil) or botanical (from seeds of various plants). There has been a lot of interest of late in the use of botanical oils other than soybean, including those derived from the seeds of plants including spearmint, rosemary and clove. This project tested for differences in the …

Spatiotemporal Dynamics Of Immature Culicines (Subfamily Culicinae) And Their Larval Habitats In Mwea Rice Scheme, Kenya, Ephantus J. Muturi, Joseph M. Mwangangi, Benjamin G. Jacob, Josephat I. Shililu, Charles M. Mbogo, John I. Githure, Robert J. Novak

All Peer-Reviewed Publications

An ecological study was conducted at three study sites in Mwea Rice Scheme, Kenya to identify the diverse aquatic habitats in which culicine mosquitoes thrived and to explore the best strategies for mosquito control in the area. During the 11-month study period, ten habitat categories and 11 culicine species mainly dominated by Culex quinquefasciatus (72.0%) and Culex annulioris (17.9%) were identified from pupae and late instars larval samples. Two of the 11 culicine species, Ficalbia (Mimomyia) plumosa and Uranotaenia spp., have not been reported previously in the study area. Rurumi had more habitat types than either of the other study …
