Comparing Mortality In Response To Simulated Climate Change In The Harvester Ant, Pogonomyrmex Badius, And The Fire Ant, Solenopsis Invicta, Haley Depner

USF Tampa Graduate Theses and Dissertations

With the rapid transport of plants, produce, and goods out of its South American home, the fire ant, Solenopsis invicta, has invaded continents on a global scale. In the United States alone, S. invicta is responsible for an estimated $1 billion in damages annually. In contrast to the invasive fire ant, Florida’s native harvester ant, Pogonomyrmex badius, is a keystone seed disperser, providing seed relocation benefits to Florida’s sandhill wildfire-adapted habitats. Seed relocation reduces seedling competition for nutrients with the parent plant, reduces predation of seeds by rodents, increases nutrient loads associated with ant mound soils, and protects seeds from …

Demonstration Farm Provides Educational Opportunity For Ipm, Nick Volesky, Mair Murray

Outcomes and Impact Quarterly

The mission of USU Extension’s Integrated Pest Management (IPM) program is to increase the use of sustainable pest management practices within urban and rural landscapes to provide economic, human, and environmental health in Utah. In the spring of 2022, the IPM program established a vegetable farm to test and demonstrate IPM practices. The farm served as an experiential learning classroom for almost 50 farmers and home gardeners.

Graduate Scholar: A Pesky Pest, Pat Melgares

Seek

Ivan Grijalva considers the sugarcane aphid a big headache. Strange, perhaps, since it would take about 16 of the pear-shaped, soft-bodied, leaf-sucking insects — lined up end to end — to measure 1 inch. In a farm field, aphids are rarely visible at first glance, even though hundreds or thousands may be present. Trivial? Not to Grijalva, Kansas State University doctoral student in entomology, who is using machine learning to detect and classify sugarcane aphid populations on sorghum leaves without the use of manual labor.

Working Out The Bugs: Piloting Library Instruction In An Online Entomology Graduate Program, Andrew Cano

UNL Libraries: Faculty Publications

Like most of its peer institutions, the University of Nebraska–Lincoln Libraries faced the challenge of meeting the needs of a growing number of students taking online courses. The author, hired as the new Virtual Learning Librarian in January 2016, was charged with creating a new Virtual Learning Program. This tutorials-based program was first fully implemented in a fully online Entomology graduate program. This paper summarizes the development of the Virtual Learning Program, how it was adapted to the Entomology program, and the initial results from the first semester of implementation.

Ento 403/803: Management Of Horticultural Crop Pests—A Peer Review Of Teaching Project Benchmark Portfolio, Thomas J. Weissling

UNL Faculty Course Portfolios

ENTO 403/803, management of horticultural crop pests, is an important class for many students. It is required by undergraduate horticulture majors at UNL, but because it is offered online, it is also of interest to entomology and horticulture graduate students across the U.S. and globally. I chose this class for the peer review process because I find it challenging due to online course delivery, and the breadth of knowledge of students that are enrolled. I feel I need to take this course to a higher level where I can engage students of all backgrounds, and ensure that each of them …

Ento 401: Insect Physiology—A Peer Review Of Teaching Project Benchmark Portfolio, Nicholas Miller

UNL Faculty Course Portfolios

Insect Physiology (ENTO 401) is a required course for majors in Insect Science. This portfolio documents my efforts to improve the course as I teach it for the second time. My intention was to use the development of a portfolio as a vehicle to modify the course so that the methods I use are better aligned to my overall goals for the course. Consequently, I have produced a portfolio that is directed toward my efforts to develop a more varied approach that improves integrated understanding and scientific thinking and to better document that the development of integrated understanding and scientific …

G73-46 Hessian Fly On Wheat, John E. Foster, Gary L. Hein

John E. Foster

This NebGuide discusses the life cycle, control and prevention of the Hessian fly. Plant-safe dates and resistant wheat varieties are also examined. The Hessian fly, Mayetiola destructor (Say), is not native to the United States, but was probably introduced by Hessian soldiers during the Revolutionary War. This insect was given its common name by Americans because of its damage on Long Island in 1779. The pest has become distributed throughout the United States wheat production areas since then. The Hessian fly belongs to the family of insects known as gall midges (Diptera: Cecidomyiidae), a group noted for their habit of …

Using Web-Based Key Character And Classification Instruction For Teaching Undergraduate Students Insect Identification, Douglas A. Golick, Tiffany M. Heng-Moss, Allen L. Steckelberg, David W. Brooks, Leon G. Higley, David Fowler

Department of Entomology: Faculty Publications

The purpose of the study was to determine whether undergraduate students receiving web-based instruction based on traditional, key character, or classification instruction differed in their performance of insect identification tasks. All groups showed a significant improvement in insect identifications on pre- and post-two-dimensional picture specimen quizzes. The study also determined student performance on insect identification tasks was not as good as for family-level identification as compared to broader insect orders and arthropod classification identification tasks. Finally, students erred significantly more by misidentification than misspelling specimen names on prepared specimen quizzes. Results of this study support that short web-based insect identification …

Nf05-653 Pyemotes Itch Mites, James A. Kalisch, David L. Keith, Alberto R. Broce

University of Nebraska-Lincoln Extension: Historical Materials

Two North American Species of itch mites — the straw itch mite and the "oak leaf gall mite" (Family Pyemotidae) — are found in Nebraska and Kansas. The straw itch mite was known in the early 1900s as a nuisance pest after farm workers handled small grains. Wheat, oats, and barley were often infested with insects on which the itch mites fed, allowing them to reach large numbers by harvest. The oak leaf gall mite recently discovered in galls on pin oaks in Lincoln, Neb., and Manhattan, Kan., is believed to be a relatively recent introduction to the United States. …

Nf05-634 Fungicides To Manage Soybean Rust: What Are The Product Differences?, Loren J. Giesler, Thomas J. Weissling

University of Nebraska-Lincoln Extension: Historical Materials

If Nebraska soybean producers find themselves needing to apply a fungicide for soybean rust this year, it will be important to choose an effective product based on the stage of disease development in the specific field. It will be important for all producers and crop managers to be aware of where soybean rust is being detected to pursue a treatment that provides the maximum return on investment for any fungicides being applied.

This NebFact discusses the fungicides available for Nebraska soybean fields and resistance management issues.
