Exploring Mitigation Options To Reduce Vehicle-Caused Mortality For The Oregon Silverspot Butterfly, Speyeria Zerene Hippolyta, Along Highway 101 At The Siuslaw National Forest, Sara B. Zielin

Environmental Science and Management Professional Master's Project Reports

The Oregon Silverspot Butterfly (OSB), Speyeria zerene hippolyta, is federally listed as "threatened." It historically inhabited coastal regions of Washington, Oregon, and California (USFWS 2001). OSB populations only remain at five sites, four of which are in Oregon; one remaining population is in California, and none exist in Washington state as they have been extirpated (BFCI 2009; USFWS 2001). The site selected for this study was Rock Creek-Big Creek, adjacent to the Siuslaw National Forest. At this site OSB habitat is bisected by Highway 101; butterflies are observed to use both sides of the highway throughout their life cycle. …

Ecological Interactions Between Spiders And The Purple Pitcher Plant, Sarracenia Purpurea, Marc Aaron Milne

Biological Sciences Theses & Dissertations

Spiders and harvestmen are commonly captured by or reside upon the carnivorous purple pitcher plant, Sarracenia purpurea. Although spiders and harvestmen are often known to be prey of S. purpurea, other ecological interactions between these arthropods and the plant are poorly understood. Studies were undertaken at three pitcher plant populations, two in Virginia and one in North Carolina, to assess the ecological relationships between spiders and harvestmen and S. purpurea. Multiple plots containing pitcher plants (treatment) and plots lacking pitcher plants (control) were created at these locations. Spiders and harvestmen were collected through five different techniques. Spatial, …

Two visibly distinct taxa of the sara orangetip fly sympatrically and synchronically in a zone northeast of Nephi, Juab County, Utah. This paper discusses how these two taxa interact based upon six character sets—adult phenotype, adult male behavior, distribution, habitat, larval coloration, and pupal shape.

Molecular Evidence For A Functional Ecdysone Signaling System In Brugia Malayi, George Tzertzinis, Ana L. Egaña, Subba Reddy Palli, Marc Robinson-Rechavi, Chris R. Gissendanner, Canhui Liu, Thomas R. Unnasch, Claude V. Maina

Entomology Faculty Publications

BACKGROUND: Filarial nematodes, including Brugia malayi, the causative agent of lymphatic filariasis, undergo molting in both arthropod and mammalian hosts to complete their life cycles. An understanding of how these parasites cross developmental checkpoints may reveal potential targets for intervention. Pharmacological evidence suggests that ecdysteroids play a role in parasitic nematode molting and fertility although their specific function remains unknown. In insects, ecdysone triggers molting through the activation of the ecdysone receptor: a heterodimer of EcR (ecdysone receptor) and USP (Ultraspiracle).

METHODS AND FINDINGS: We report the cloning and characterization of a B. malayi EcR homologue (Bma-EcR). Bma-EcR dimerizes with …

Occurrence Of The Milliped, Hiltonius Carpinus Carpinus Chamberlin, 1943 (Spirobolida: Spirobolidae), In The United States And New Records From Mexico, Rowland M. Shelley

Insecta Mundi

Hiltonius carpinus carpinus Chamberlin, 1943 (Spirobolida: Spirobolidae), is authoritatively recorded from the United States for the first time; it is known only from southern/southeastern Arizona but should be expected in adjoining counties of New Mexico. The northernmost locality is the Pinaleno Mountains, Graham County, and its distribution extends to southern Mexico; the other subspecies, H. c. vulcan (Chamberlin, 1953), occurs in Guatemala. The range of H. c. carpinus includes the type locality of the enigmatic H. fossulifer (Pocock, 1908), lending credence to prior suggestions that the names are synonymous. Three new Mexican states – Durango, Jalisco, and Nuevo León – …

Mitochondrial Phylogenomics Of The Bivalvia (Mollusca): Searching For The Origin And Mitogenomic Correlates Of Doubly Uniparental Inheritance Of Mtdna, Hélène Doucet-Beaupré, Sophie Breton, Eric G. Chapman, Pierre U. Blier, Arthur E. Bogan, Donald T. Stewart, Walter R. Hoeh

Entomology Faculty Publications

BACKGROUND: Doubly uniparental inheritance (DUI) is an atypical system of animal mtDNA inheritance found only in some bivalves. Under DUI, maternally (F genome) and paternally (M genome) transmitted mtDNAs yield two distinct gender-associated mtDNA lineages. The oldest distinct M and F genomes are found in freshwater mussels (order Unionoida). Comparative analyses of unionoid mitochondrial genomes and a robust phylogenetic framework are necessary to elucidate the origin, function and molecular evolutionary consequences of DUI. Herein, F and M genomes from three unionoid species, Venustaconcha ellipsiformis, Pyganodon grandis and Quadrula quadrula have been sequenced. Comparative genomic analyses were carried out on these …

Comparison Of Cucumber Beetle (Coleoptera: Chrysomelidae) And Cumulative Soil Insect Damage In Three Sweetpotato Varieties Evaluated Under Selected Preplant Incorporated Insecticide Regimes In Louisiana, T. P. Smith, A. M. Hammond, R. N. Story, E. Burris

Midsouth Entomologist

Soil insects are a limiting factor in sweetpotato production in the United States. Studies were conducted in 2006 and 2007 at the LSU AgCenter Sweet Potato Research Station in Chase, LA, which evaluated the effect of labeled preplant insecticide treatments on subsequent insect damage and yield of Beauregard, Evangeline, and Covington sweetpotato varieties. Sweetpotato producers commonly apply one or more preplant insecticides prior to transplanting. These experiments examined the efficacy of select labeled insecticides applied as close to transplanting as possible without the addition of postplant insecticide applications. The majority of insect damage during 2006 and 2007 was attributed to …

Phenotypic And Genotypic Characters Associated With The Polygyne Hybrid Imported Fire Ant, R. B. Garlapati, D. C. Cross, M. A. Caprio, S. Sabanadzovic, J. Chen

Midsouth Entomologist

A study was initiated to identify the origin of polygyny in the hybrid imported fire ant (Solenopsis invicta × richteri) and to confirm the association of polygyne phenotypic and genotypic characters. Polygyny is known to occur in both species in their native ranges in South America. Gp-9, a major gene in imported fire ants, is associated with the expression of social form. Variants of the monogyne allele, Gp-9B, and the polygyne allele, Gp-9b, have been sequenced for both species. The association of phenotypic and genotypic characters in a hybrid imported fire ant colony is strongly indicated by identification of multiple …

Evaluation Of Pre-Plant Soil-Incorporated Insecticides For Control Of Sweetpotato Pests, 2009, J. T. Reed, D. Bao, C. S. Jackson

Midsouth Entomologist

Preplant-incorporated insecticides were evaluated for efficacy against root-feeding insect pests of sweetpotato in research plots at Mississippi State University, Mississippi State, MS. Preplant-incorporated insecticides did not affect numbers of insects sampled in sweetpotato foliage; however, all treatments provided nearly complete control of root-damaging insects that caused damage to nearly 80% of roots in water-treated check plots. Combining chlorpyrifos and bifenthrin as a pre-plant soil-incorporated application provided no additional benefit in this trial compared with either compound used alone.
