Advantages Of Understanding The Lady Beetle Diet, Jonathan Lundgren

Agricultural Research Magazine

Understanding the feeding behavior of lady beetles will help agronomists develop cropping systems that best use these important beneficial insects as biological controls of insect pests, such as aphids and Colorado potato beetles.

Agricultural Research Service entomologist Jonathan Lundgren at the North Central Agricultural Research Laboratory in Brookings, South Dakota, and former ARS entomologist Michael Seagraves were part of a team of ARS and university scientists that examined how lady beetle diets alter their feeding patterns and physiology.

Appreciated for their ability to eat insect pests, lady beetles also consume nectar, pollen, and other plant tissue. Indeed, most beneficial predators …

New Technology For Harvesting The Power Of Beneficial Fungi, Mark Jackson, Jan Suszkiw

Agricultural Research Magazine

Biopesticides containing beneficial fungi are often grown on grains or other solids, but Agricultural Research Service scientists have found that a liquid diet might be cheaper and better. The approach, known as “liquid culture fermentation,” offers several advantages, including lower material costs and increased yields of certain forms of pestkilling fungi like Isaria or Metarhizium that can be sprayed directly onto crop plants or applied to soil as a biological alternative to using synthetic pesticides.

For decades, biopesticide makers have cultured fungi like these on moistened grains or other solid substrates to prompt them into churning out billions of specialized …

Ars Works Toward Control Of Brown Marmorated Stink Bug, Sharon Durham, Dennis O’Brien

Agricultural Research Magazine

The brown marmorated stink bug (BMSB) is wreaking havoc in U.S. homes, gardens, and agricultural operations, causing personal and economic woe. Agricultural Research Service scientists are exploring various aspects of monitoring and control of this increasingly important insect pest, which is an invasive Asian species known as a sporadic pest of many tree fruit crops in China, Korea, and Japan. Along with being a household nuisance, it is a major economic threat to producers of orchard fruits such as apple, peach, and pear; garden vegetables and row crops; and many ornamental species.

Since its detection in the northeastern United States …

Fight Or Flight: Parental Decisions About Predators At Nests Of Northern Bobwhites (Colinus Virginianus), Susan N. Ellis-Felege, Jonathan S. Burnam, William E. Palmer, D. Clay Sisson, John P. Carroll

School of Natural Resources: Faculty Publications

Patterns of nest defense against predators by ground-nesting bird species in the wild are poorly understood, largely because of a historical inability to directly monitor nests. Most nest-defense studies have observed responses elicited from artificial predators or human observers presented to nesting birds, and few have attempted to present these events in the context of predator–prey relationships found in the wild. We hypothesized that predator threat level (e.g., the threat posed to the clutch or to the clutch and the attending adult), parental characteristics, clutch investment, and future reproductive opportunities would influence avian nest-defense decisions. During 1999–2006, we examined predation …

Evaluation Of Electrostatic Particle Ionization And Biocurtain™ Technologies To Reduce Air Pollutants From Broiler Houses, Sheryll B. Jerez, W Faulkner, K. D. Casey, M S. Borhan, R. A. Smith

Faculty Publications

The continuing growth of poultry production, along with the increasing urbanization of rural areas, is leading to more odor-related complaints from neighboring communities and more scrutiny from policy makers. It is, therefore, in the best interest of poultry producers to look at control methods for abating odors. Previous studies have shown that substantial amounts of volatile and odorous compounds are adsorbed and transported by dust particles. Thus, by reducing the amount of dust emitted from poultry facilities such as broiler houses, odor may be reduced as well. The objective of this study was to evaluate the effectiveness of two commercially …

Effectiveness Of Manual Palpation In The Northern Water Snake, Nerodia Sipedon Sipedon, As A Method To Extract Gut Contents For Dietary Studies, Marcella Ann Cruz

Theses, Dissertations and Capstones

The Common Water Snake, Nerodia sipedon sipedon, is one of six subspecies, and the only species of Nerodia to inhabit West Virginia. Because it is abundant and information on the species is lacking within the state, it was used as my study organism. The effectiveness of manual palpation, the most commonly used method in snake diet related studies, was tested against museum dissection by comparing presence and absence of gut contents. Nineteen individuals of 76 manually palpated collected snakes were compared to 6 individuals of 37 dissected snakes using a Pearson chi-square analysis. Results suggested manual palpation is an effective …

Examining Habitat Selection And Home Range Behavior At Multiple Scales In A Population Of Eastern Box Turtles, (Terrapene C. Carolina), With Notes On Demographic Changes After 17 Years, Brian Anthony Williamson

Theses, Dissertations and Capstones

The Eastern Box Turtle, Terrapene c. carolina, is a terrestrial species native to the eastern United States. Once considered common, it is currently declining in much of its range due to habitat destruction and disease. To conserve the species, knowledge of Eastern Box Turtle habitat selection and the factors influencing their movement is necessary. Although the home range behavior of the Eastern Box Turtle has been well studied, few studies have quantified habitat selection at the home-range scale. Therefore, I examined home-range selection and within home range habitat selection in a population of Eastern Box Turtles at Hungry Beech Nature …

Filling In The Gaps In Phenology And Life History Of The Cumberland Plateau Salamander (Plethodon Kentucki), Robert C. Bowers

Theses, Dissertations and Capstones

The Cumberland Plateau Salamander, Plethodon kentucki, is a member of the Plethodon glutinosus complex comprising 16 sibling species, which are best differentiated by range. Few studies have been conducted to gain information on the natural history of P. kentucki. To alleviate this, two sites at Beech Fork State Park in Wayne County, West Virginia were used to study the salamander’s general life history with emphasis on reproduction, phenology, and population size. At each site, three 20m x 20m sample plots were arranged based on viability of the habitat for P. kentucki. Ground searches of all cover objects …

Gene Transfer In A Newly Established Spontaneous Feline Fibrosarcoma Cell Line, Rounak Nande

Theses, Dissertations and Capstones

Fibrosarcoma is a deadly disease in cats and is most often located at classical vaccine injections sites. More rare forms of spontaneous non-vaccination site (NSV) fibrosarcomas have been described and have been found associated to genetic alterations.

Purpose of this study was to compare the efficacy of adenoviral gene therapy in NVS fibrosarcoma. The NVS fibrosarcoma cell line (Cocca-6A) was isolated from a spontaneous fibrosarcoma that occurred in a domestic calico cat. Cocca-6A fibrosarcoma cells were morphologically and cytogenetically characterized. The feline cells were karyotyped and their chromosome number was counted using a Giemsa staining. Giemsa block staining of metaphase …

Examining The Influence Of Mating Systems On Testes Size In Salamanders, Howard James Stanton Ii

Theses, Dissertations and Capstones

Sperm competition theory predicts that relatively larger testes sizes evolve in animals with polygamous mating systems compared to those in monogamous mating systems due to sperm competition. Whereas intensity of sperm competition is the significant predictor of testes sizes in other taxa such as mammals, frogs, birds, insects, and fish, in salamanders the intensity of male-male competition in the transfer of spermatophores to females is predicted to be a critical factor. This is because males have to deposit more spermatophores to secure reproductive pay-off under higher intensity of male-male competition. I hypothesized that salamander species that breed explosively as groups …

Quantitative Reconstruction And Two-Dimensional, Steady Flow Hydrodynamics Of The Plesiosaur Flipper, Mark Cruz Deblois

Theses, Dissertations and Capstones

Plesiosaurs are a group of extinct marine reptiles that thrived during the Mesozoic Era. They are unique for swimming with two hydrofoil-shaped flippers. Penguins, sea turtles, and cetaceans all have hydrofoil shaped flippers but penguins and sea turtles only use the front pair to produce thrust and cetaceans use their tail flukes. Consequently, the mode of swimming for plesiosaurs has long been debated. However, a quantitative study of the hydrodynamic properties of the flippers, which would constrain inference about their mode of swimming, has not yet been done. The main reason is that the trailing edge of the plesiosaur flipper …

Ontogenetic State Of A Juvenile Polycotylid Plesiosaur (Sauropterygia: Plesiosauria) And Its Implications For Plesiosaur Growth, Christina Joanne Byrd

Theses, Dissertations and Capstones

Understanding ontogenetic variation in plesiosaurs from the family Polycotylidae can provide insight into the evolutionary history of this group of extinct short-necked marine reptiles from the Cretaceous period. In this study, I analyzed a juvenile polycotylid plesiosaur from the University of Nebraska State Museum (UNSM 55810). UNSM 55810 came from the Pierre Shale (99-65 Ma) of Nebraska and possesses skeletal elements that include a partial skull, nearly complete pectoral and pelvic girdles, and an assortment of paddle elements. Based on several cranial characteristics, this specimen is probably referable to the genus Dolichorhynchops. Previous qualitative studies have included UNSM 55810 but …
