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 …

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. …
