Abundance Of Rice Root Aphid Among Selected Plant Species And On Plants Grown With Different Soil-Surface Media, Louis S. Hesler, S. Dean Kindler

The Great Lakes Entomologist

The rice root aphid, Rhopalosiphum rufiabdominalis (Sasaki), is distributed worldwide and colonizes a wide range of plants. However, relatively little is known about the suitability of different host plants, optimal rearing techniques, and the aphid’s impact on plant fitness. To improve understanding of these factors, laboratory experiments were conducted to compare the abundance of rice root aphid on plants grown using three different soil-surface media and among selected monocotyledonous and dicotyledonous plants. Rice root aphid was more abundant on plants grown with a sandy soil surface than a surface with fine wood chips or only bare non-sandy soil. Rice root …

Secondary Predation On The Horsehair Worm Gordius Robustus (Nematomorpha: Gordiida), Philip A. Cochran

The Great Lakes Entomologist

The gut contents of a brown trout (Salmo trutta) included horsehair worms (Gordius robustus, Nematomorpha: Gordiida) emerging from a camel cricket (Ceuthophilus sp., Orthoptera: Gryllacrididae). This provides more evidence of secondary ingestion than most previous reports of predation on horsehair worms, but it also illustrates the difficulty of distinguishing in practice between direct and secondary predation.

Lycaeides Melissa Samuelis (Lepidoptera: Lycaenidae) Response To An Aggregation Of Lytta Sayi (Coleoptera: Meloidae) On Lupinus Perennis (Fabaceae, Jodi A. I Swanson, Paula K. Kleintjes Neff

The Great Lakes Entomologist

Lycaeides melissa samuelis Nabokov, frequently called the Karner blue butterfly, is a Federally endangered species found in savanna/barren type ecosystems of New England and the Great Lakes region of North America. We observed sporadic and localized feeding aggregations of Lytta sayi LeConte (Coleoptera: Meloidae) on Lupinus perennis L. (Fabaceae) occupied by L. m. samuelis during the summers of 2000-2004, in Eau Claire County, Wisconsin. In 2004, we quantified the phenology and behavior of an aggregation (> 900 beetles) within a 1,020 m2 stand of lupine and measured its effect upon adult L. m. samuelis behavior. The L. sayi aggregation formed …

Alfalfa Snout Beetle, Otiorhynchus Ligustici L. (Coleoptera: Curculionidae): Methods For Egg Collection And Larval Rearing, Elson J. Shields, Gabor Neumann, Antonio M. Testa

The Great Lakes Entomologist

The alfalfa snout beetle, Otiorhynchus ligustici L., is the most serious pest of alfalfa in northern New York State. Recent research efforts focused on the biological control of this insect require the availability of all life stages. With a 2-year lifecycle and a mandatory diapause, the artificial rearing of a laboratory culture appears to be a non-viable option at present, but methods described here can be used to obtain sufficient numbers of eggs and larvae over an extended period of time for research purposes. The crowding of adult beetles in egg production units (cups) had a significant, negative effect on …

Female Fighting And Host Competition Among Four Sympatric Species Of Melittobia (Hymenoptera: Eulophidae), Robert W. Matthews, Leif D. Deyrup

The Great Lakes Entomologist

Melittobia is a genus of parasitic wasps well known for high levels of inbreeding and violent male combat. Casual observations of groups of sisters of M. femorata placed with hosts revealed a surprising incidence of body mutilations (broken or missing tarsi, antennae, and wings). Replicated conspecific groups of 1, 2, or 3 females of M. femorata, M. digitata, and M. australica and interspecific groups of M. femorata and M. australica (2:1) were observed over their first 10 days in newly established cultures, and the incidence of mutilation was recorded. In some groups females were dye-fed, allowing us to subsequently chart …

Fungal Pathogens Infecting Soybean Aphid And Aphids On Other Crops Grown In Soybean Production Areas Of Michigan, Takuji Noma, Michael J. Brewer

The Great Lakes Entomologist

Seasonal prevalence of fungal pathogens infecting soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), was assessed from 2004 to 2006 in two Michigan soybean production areas. In 2005 and 2006 field-collected soybean aphids were incubated, and fungal infection was detected at both sites early in August 2005 during soybean pod development and high soybean aphid densities. Significantly higher proportions of winged aphid morphs were infected (20 and 90% infection at the two sites) than wingless aphid morphs (1 and 3% infection). All cases of mycosis examined involved one pathogen species, Pandora neoaphidis (Remaudiére & Hennebert) Humber (Entomophthorales: Entomophthoraceae). In 2004 and …

Do Generalist Tiger Swallowtail Butterfly Females Select Dark Green Leaves Over Yellowish – Or Reddish-Green Leaves For Oviposition?, Rodrigo J. Mercader, Rory Kruithoff, J. Mark Scriber

The Great Lakes Entomologist

In late August and September, using leaves from the same branches, the polyphagous North American swallowtail butterfly species Papilio glaucus L. (Lepidoptera: Papilionidae) is shown to select mature dark green leaves of their host plants white ash, Fraxinus americana L. (Oleaceae) and tulip tree, Liriodendron tulipifera L. (Magnoliaceae) rather than the pale green or yellowish- green mature leaves in laboratory oviposition arenas. In early August, similar results were observed for black cherry, Prunus serotina Ehrh. (Rosaceae). Dark green leaves were preferred over light green and yellowish green leaves. These green leaves of black cherry were the most nutritious leaves for …

Notes On Dianthidium Simile (Cresson) (Hymenoptera: Megachilidae) In Michigan, Mark F. O'Brien

The Great Lakes Entomologist

Dianthidium simile (Cresson) is a small ground-nesting megachilid bee restricted to sandy areas in Michigan, often bordering lakeshores. Females dig their nests in sand, at the base of dried clumps of grass. Nests are small clusters of cells, formed from conifer resin and sand grains, with each 1-1.5 cm in length by 8.5 mm in diameter. Collection records and field observations indicate a flight period from late June to early September. This is the first report on the behavior of this species.

Presence Of The “Threatened” Trimerotropis Huroniana (Orthoptera: Acrididae) In Relation To The Occurrence Of Native Dune Plant Species And The Exotic Centaurea Biebersteinii, Jordan M. Marshall, Andrew J. Storer

The Great Lakes Entomologist

Trimerotropis huroniana Wlk. is a “Threatened” species in Michigan and Wisconsin with a distribution limited to open dune systems in the northern Great Lakes region of North America. Pitfall traps were utilized in the Grand Sable Dunes of Pictured Rocks National Lakeshore, MI, along with an herbaceous plant survey, to identify the relationship of T. huroniana with native dune plant species, Ammophila breviligulata Fern. (American beachgrass, Poaceae), Artemisia campestris L. (field sagewort, Asteraceae), and the exotic invasive plant Centaurea biebersteinii DC. [=Centaurea maculosa, spotted knapweed, Lamarck] (Asteraceae). The absence of C. biebersteinii resulted in an increased likelihood of …

Behaviors Of Adult Agrilus Planipennis (Coleoptera: Buprestidae), Cesar R. Rodriguez-Soana, James R. Miller, Therese M. Poland, Tina M. Kuhn, Gard W. Otis, Tanya Turk, Daniel L. Ward

The Great Lakes Entomologist

A 2-year study was conducted in Canada (2003) and the United States (2005) to better understand searching and mating behaviors of adult Agrilus planipennis Fairmaire. In both field and laboratory, adults spent more time resting and walking than feeding or flying. The sex ratio in the field was biased towards males, which tended to hover around trees, likely looking for mates. There was more leaf feeding damage within a tree higher in the canopy than in the lower canopy early in the season, but this difference disappeared over time. In choice experiments, males attempted to mate with individuals of both …

Pedagogical Education Practices In Communication Sciences And Disorders Phd Programs: A Pilot Study, Laura Smith-Olinde, Stanley K. Ellis

Teaching and Learning in Communication Sciences & Disorders

The purpose of this study was two-fold: (1) to ascertain how research doctoral programs in Communication Sciences and Disorders (CSD) characterize their own efforts to educate research doctoral students about teaching at the college/university level; and (2) whether and how programs introduce the “scholarship of teaching and learning” (SoTL) to PhD students. PhD program directors (N=69) were emailed a survey for descriptions of university teaching instruction and SoTL activities, with a 27.5% return rate (n=19). Quantitative and qualitative analyses were used. Identified themes included, “course or seminar”, “experiential” and “required”. One hundred per cent of respondents offer teaching experiences and …

No More Reason For Ignoring Gelatinous Zooplankton In Ecosystem Assessment And Marine Management: Concrete Cost-Effective Methodology During Routine Fishery Trawl Surveys, A. Aubert, E. Antajan, C. Lynam, S. Pitois, A. Pliru, S. Vaz, D. Thibault

Student Publications

Gelatinous zooplankton, including cnidarians, ctenophores, and tunicates (appendicularians, pyrosomes, salps and doliolids), are often overlooked by scientific studies, ecosystem assessments and at a management level. Despite the important economic consequences that they can have on human activities and on the marine food-web, arguments often related to the costs of monitoring or their coordination, or simply negligence, have resulted in the absence of relevant monitoring programs. A cost-effective protocol has been applied on trawling from existing fishery surveys conducted by national laboratories in England and France. The testing phase has successfully demonstrated the adequacy of such a tool to sample …

What is Groundwater? Groundwater is simply any water that is found in underground permeable rock layers known as aquifers

Industrial Impact, Sravani Ponnaluri '20, Emily Gonda '20

UN Sustainable Development Goals Infographics

Industries burn fossil fuels to create goods which releases carbon dioxide into the atmosphere. CO2 contributes to 20% of the world's greenhouse effect, and the level of it in the atmosphere has increased to over 400 ppm when before the French Revolution it fluctuated between 180-280 ppm (NASA, 2016). The coal industry is a big contributor as it contributes to 35% of the total U.S. energy related CO2 emissions (EIA, 2017). This all leads to global warming, which causes rising sea levels, longer plant growing seasons, and an increase in forest fires (NASA).

Influence Of Damming On Anuran Species Richness In Riparian Areas: A Test Of The Serial Discontinuity Concept, Jacquelyn C. Guzy, Evan A. Eskew, Brian J. Halstead, Steve J. Price

Forestry and Natural Resources Faculty Publications

Almost all large rivers worldwide are fragmented by dams, and their impacts have been modeled using the serial discontinuity concept (SDC), a series of predictions regarding responses of key biotic and abiotic variables. We evaluated the effects of damming on anuran communities along a 245‐km river corridor by conducting repeated, time‐constrained anuran calling surveys at 42 locations along the Broad and Pacolet Rivers in South Carolina, USA. Using a hierarchical Bayesian analysis, we test the biodiversity prediction of the SDC (modified for floodplain rivers) by evaluating anuran occupancy and species diversity relative to dams and degree of urbanized land use. …

Present And Future Thermal Environments Available To Sharp-Tailed Grouse In An Intact Grassland, Edward J. Raynor, Larkin Powell, Walter H. Schacht

School of Natural Resources: Faculty Publications

Better understanding animal ecology in terms of thermal habitat use has become a focus of ecological studies, in large part due to the predicted temperature increases associated with global climate change. To further our knowledge on how ground-nesting endotherms respond to thermal landscapes, we examined the thermal ecology of Sharp-tailed Grouse (Tympanuchus phasianellus) during the nesting period. We measured site-specific iButton temperatures (TiB) and vegetation characteristics at nest sites, nearby random sites, and landscape sites to assess thermal patterns at scales relevant to nesting birds. We asked if microhabitat vegetation characteristics at nest sites matched the characteristics that directed macrohabitat …

Comparison Of Processed And Non-Processed Biomass Digestion, Richard Bruce Clark Iii

Graduate Theses - Chemistry and Biochemistry

Lignocellulosic ethanol is the main focus of second-generation biofuels [1]. Because cellulose is the most abundant organic material on earth, second-generation biofuels are a more sustainable option than the classical first-generation biofuels that use foodstuffs as the main feedstock in ethanol production [1]. Furthermore, biofuel can be produced not only from unprocessed biomass such as corn husks but also from processed material like paper [1]. Ionic liquids have shown to be quite effective in dissolving naturally occurring, and traditionally insoluble, polymers such as cellulose into solution, and cellulase enzymes have been shown to effectively digest cellulose into simple sugars [2]. …

Acinetobacter Bacteriophage Discovery In Soil, Michael Plaskett

Rose-Hulman Undergraduate Research Publications

The Acinetobacter genus is home to a wide range of bacteria that are gram-negative, aerobic, non-motile, oxidase-negative, catalase positive, and coccobacilli with a G+C content of 39 to 47% (Bergogne-Berezin, 1996). These bacteria are universal as they reside in the soil, water, sewage, various surfaces; and are also able to infect humans; however, a majority of the infections are caused by the species Acinetobacter baumannii. This bacterium is the most prevalent etiological cause of the Acinetobacter infections due to it being a nosocomial infection or one that is acquired in a health care setting. The infections that occur in a …

Investigating The Response Of Magnetotactic Bacteria To Varying Field Strength And Developing Autonomous Analysis Of Spatial Dispersal, Madeleine D. Pasco

Rose-Hulman Undergraduate Research Publications

Magnetotactic bacteria (MTB) are single-celled organisms which contain organelles called “magnetosomes,” membrane-bound ferrous nanocrystals. These organelles allow for magnetotaxis, which is movement guided by magnetic fields. MTB are generally found in the top layers of sediment of aqueous environments, and magnetotaxis is thought to help guide these microbes to ideal oxygen concentrations in the water after they may have been displaced by turbulent waters. In this we study the effect of the strength of a magnetic field on magnetotaxis.
