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, …

The Taxonomic Report of the International Lepidoptera Survey

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 – …

Prospects For The Development Of Odour Baits To Control The Tsetse Flies Glossina Tachinoidesand G. Palpalis S.L., J. B. Rayaisse, I. Tirados, D. Kaba, S. Y. Dewhirst, J. G. Logan, A. Diarrassouba, E. Salou, M. O. Omolo, P. Solano, M. J. Lehane, J. A. Pickett, G. A. Vale, S. J. Torr, J. Esterhuizen

All Peer-Reviewed Publications

Field studies were done of the responses of Glossina palpalis palpalis in Côte d'Ivoire, and G. p. gambiensis and G. tachinoides in Burkina Faso, to odours from humans, cattle and pigs. Responses were measured either by baiting (1.) biconical traps or (2.) electrocuting black targets with natural host odours. The catch of G. tachinoides from traps was significantly enhanced (∼5x) by odour from cattle but not humans. In contrast, catches from electric targets showed inconsistent results. For G. p. gambiensis both human and cattle odour increased (>2x) the trap catch significantly but not the catch from electric targets. For …

Molecular Diagnosis Of A Previously Unreported Predator-Prey Association In Coffee: Karnyothrips Flavipes Jones (Thysanoptera: Phlaeothripidae) Predation On The Coffee Berry Borer, Juliana Jaramillo, Eric G. Chapman, Fernando E. Vega, James D. Harwood

All Peer-Reviewed Publications

The coffee berry borer, Hypothenemus hampei, is the most important pest of coffee throughout the world, causing losses estimated at US 500 million/year. The thrips Karnyothrips flavipes was observed for the first time feeding on immature stages of H. hampei in April 2008 from samples collected in the Kisii area of Western Kenya. Since the trophic interactions between H. hampei and K. flavipes are carried out entirely within the coffee berry, and because thrips feed by liquid ingestion, we used molecular gut-content analysis to confirm the potential role of K. flavipes as a predator of H. hampei in an organic …

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.

2009 Soybean Insect Losses For Mississippi, Tennessee, And Arkansas, F. R. Musser, G. M. Lorenz, S. D. Stewart, A. L. Catchot Jr.

Midsouth Entomologist

Survey-based soybean insect losses provide a glimpse of current soybean management practices and allow one to see evolving trends. This survey was initiated in MS in 2004, and in Tennessee in 2008. This year is the first year that Arkansas has conducted the survey. The 2009 survey shows stink bugs were the primary pest in all three states, but were less widespread than in 2008. Corn earworm pressure was much higher in 2009 than in previous years. Insect scouting and the adoption of seed treatments continued to increase in 2009.

Ecological Niche And Potential Geographic Distribution Of The Invasive Fruit Fly Bactrocera Invadens (Diptera, Tephritidae), M. De Meyer, M. P. Robertson, M. W. Mansell, S. Ekesi, K. Tsuruta, W. Mwaiko, J. F. Vayssières, A. T. Peterson

All Peer-Reviewed Publications

Two correlative approaches to the challenge of ecological niche modeling (genetic algorithm, maximum entropy) were used to estimate the potential global distribution of the invasive fruit fly, Bactrocera invadens, based on associations between known occurrence records and a set of environmental predictor variables. The two models yielded similar estimates, largely corresponding to Equatorial climate classes with high levels of precipitation. The maximum entropy approach was somewhat more conservative in its evaluation of suitability, depending on thresholds for presence/absence that are selected, largely excluding areas with distinct dry seasons; the genetic algorithm models, in contrast, indicate that climate class as partly …

Corn Stalk Penetration Resistance As A Predictor Of Southwestern Corn Borer (Lepidoptera: Crambidae) Survival, B. K. Gibson, C. D. Parker, F. R. Musser

Midsouth Entomologist

Studies were conducted to determine if corn stalk strength had an effect on southwestern corn borer (Diatraea grandiosella Dyar) survival during different growth stages. In 2006 southwestern corn borer larvae were placed on corn plants during dough stage near the ear and base of the plant. Penetration resistance was lower and borer survival was higher near the ear than near the base of the plant. In 2007, five corn hybrids were planted at three locations in Mississippi. Plants were infested with five 3rd instars at the ear zone during tassel, dough, and dent stages. Survival decreased as the corn progressed …

Swarming Of The Formosan Subterranean Termite (Isoptera: Rhinotermitidae) In Southern Mississippi, A. R. Lax, B. A. Wiltz

Midsouth Entomologist

Swarms of Formosan subterranean termites, Coptotermes formosanus Shiraki, (FST) in Southern Mississippi were monitored from mid-April through late June, 2007-2009. Distribution of swarming colonies was recorded at 69 traps within Poplarville (Pearl River County) and an additional 45-65 traps, along transects in Pearl River, Lamar, Forrest, and Stone Counties. Swarms were first detected during the week ending April 27 and continued through the final collection dates in late June. In Poplarville, FST colonies were ubiquitous, with 68 of 69 traps catching alates on at least one of the 2009 sampling dates. Along highway transects, FST was collected from 36% of …
