Wireworms, Ryan Davis, Jay B. Karren, Alan H. Roe
Wireworms, Ryan Davis, Jay B. Karren, Alan H. Roe
All Current Publications
Wireworms are the larvae (immatures) of click beetles. Adults are elongate, slender, hardshelled beetles that take their name from their habit of flipping into the air (sometimes with an audible clicking sound) when they are placed on their backs. This fact sheet reviews the management of wireworms.
The Impacts Of Prescribed Burning And Mechanical Thinning On Insect Communities In The Arkansas Ozarks, Aaron P. Tormanen
The Impacts Of Prescribed Burning And Mechanical Thinning On Insect Communities In The Arkansas Ozarks, Aaron P. Tormanen
Theses and Dissertations from 2020
Insects are important in woodland ecosystems due to their role as pollinators and as prey for bats. My research investigated the relationships between forest management, vegetation, and insects in the Ozark National Forest in Arkansas. I selected 30 stands burned at varying frequencies in the last 12 years. Twelve of these stands were burned and mechanically thinned, 12 were only burned, and 6 were untreated. I deployed blacklight traps and malaise traps in each stand monthly from mid-March to mid- November 2019. Over 42,391 insects were collected, and Lepidoptera was the most abundant order. Insects were dried, weighed, and identified …
Influence Of Traditional And Dual-Use Cropping On Arthropods And Slugs In Soybean In Tennessee, Matthew L. Longmire
Influence Of Traditional And Dual-Use Cropping On Arthropods And Slugs In Soybean In Tennessee, Matthew L. Longmire
Masters Theses
Soybean is the number one agricultural crop in Tennessee for both number of hectares planted and economic value. Soybean, used in various products, is marketed globally. In recent years, Tennessee soybean growers have shown an increased interest in the use of cover crops with soybean. A cover crop is planted before the cash crop and can minimize some weeds, diseases, insects, and other pests. Traditionally, cover crops are terminated in the spring before cash crop planting. Traditional methods of cover cropping provide many benefits but can also produce some undesired results. Dual-use cover cropping is a newer method of cover …
From Aristotle To Wunderkammer: The Development Of Entomology And Insect Collections, Erica Fischer
From Aristotle To Wunderkammer: The Development Of Entomology And Insect Collections, Erica Fischer
Honors Projects
This project aimed to analyze the development of insect classification and the shift from the realm of the amateur naturalist to professional science. It looked to address questions regarding entomology as a developing science and how effectively it reflects larger changes in the field of biology and the development of natural history collections. This work was for a synthesis of time periods from the beginnings of classification in the ancient world through the 20th century, a more general timeline than is typically approached. The research needed for the completion of this paper was based on secondary source research in the …
Current Applications And Limitations Of Forensic Entomology, Helena Volckaert
Current Applications And Limitations Of Forensic Entomology, Helena Volckaert
Themis: Research Journal of Justice Studies and Forensic Science
Forensic entomology is the study of arthropods concerning their application in crime scene investigation as a method of predicting postmortem interval (PMI) in deceased or missing individuals. PMI is determined by the life stage of insects present on-scene. Insects used in criminal investigations are primarily beetles, flies, or moths; this may also include various scavenging insects and hitchhiking mites. These creatures help colonize decayed tissue, providing crime scene personnel with live specimens collected and examined for biological evidence. Forensic entomology is currently a niche application in most investigations—as qualified entomologists are often needed—and proper analysis of collected evidence can be …
The Relative Abundance And Diversity Of Parasitoids Of The Browntail Moth (Euproctis Chrysorrhoea L.) And Factors That Influence Their Population Dynamics, Karla S. Boyd
Electronic Theses and Dissertations
The browntail moth (Euproctis chrysorrhea) is an invasive forest pest that has been present in the Northeast since it was first introduced from Europe in 1897. Originally, its range expanded very rapidly until it reached its peak invasion of 150,000 km2, which included most of New England and parts of Southern Canada and Long Island, NY, in 1915. After this point, its range collapsed until only relic populations remained on islands in the Casco Bay Region of Maine and outer Cape Cod in Massachusetts. In 2016, a large population outbreak occurred that expanded its range into …
Cankerworms, Marion Murray, Erin W. Hodgson
Cankerworms, Marion Murray, Erin W. Hodgson
All Current Publications
Cankerworms, also known as inchworms, are in the order Lepidoptera and family Geometridae. Geometrid moth adults have slender bodies and relatively large, broad forewings (Figs. 1, 3). Both fall, Alsophila pometaria, and spring, Paleacrita vernata, cankerworms occur in Utah, with the fall cankerworm being most common.
Further New Records Of Coleoptera And Other Insects From Wisconsin, Jordan D. Marche Ii
Further New Records Of Coleoptera And Other Insects From Wisconsin, Jordan D. Marche Ii
The Great Lakes Entomologist
Specimens of eleven different species of insects, representing seven separate families of Coleoptera, and one family each of Hemiptera, Lepidoptera, Diptera, and Hymenoptera, are herein reported as new to Wisconsin. These genera or species occur respectively within the following families: Leiodidae, Monotomidae, Cucujidae, Cryptophagidae, Ciidae, Tetratomidae, Curculionidae, Pentatomidae, Glyphipterigidae, Phoridae, and Pteromalidae. All but one of these insects were collected at or near the author’s residence (Dane County); the pentatomid was taken in northern Wisconsin (Oconto County). Three of the four non-coleopteran fauna are introduced species.
Codling Moth In Utah Orchards, Marion Murray, Diane G. Alston
Codling Moth In Utah Orchards, Marion Murray, Diane G. Alston
All Current Publications
Codling moth (Order Lepidoptera, Family Tortricidae) is the most serious pest of apple and pear worldwide. In most commercial fruit producing regions and home yards in Utah, fruit must be protected to harvest a crop. Insecticides are the main control tactic. There are new insecticides available, many of which are less toxic to humans and beneficial insects and mites than earlier insecticides. For commercial orchards with more than 10 acres of contiguous apple and pear plantings, pheromone-based mating disruption can greatly reduce codling moth populations to allow reduced insecticide use.
Codling Moth Mating Disruption, Marion Murray, Diane G. Alston
Codling Moth Mating Disruption, Marion Murray, Diane G. Alston
All Current Publications
Mating disruption became commercially available in the early 1990s, and was adopted by many Utah growers about a decade later. Use of this pest management technology can be daunting due to high up-front costs and monitoring requirements; however, after two to three seasons of use, the cost of mating disruption is the same or even less than conventional pest management.
Rapid Evolution In Agroecosystems: Transposable Elements And Epigenetics In The Colorado Potato Beetle, Kristian Brevik
Rapid Evolution In Agroecosystems: Transposable Elements And Epigenetics In The Colorado Potato Beetle, Kristian Brevik
Graduate College Dissertations and Theses
Within agricultural ecosystems, humans and insects enter into complex relationships. Humans consider many of these insects to be pests, and exert significant pressures upon them, such as efforts to kill them using insecticides. One of the ways insects respond to these efforts is by rapidly evolving resistance to insecticides - but how they do this is not fully understood. DNA methylation, an epigenetic mechanism, and transposable elements, which are mobile genetic elements within genomes, may each play a role in shaping the way insects rapidly evolve in response to exposure to insecticides. Understanding the role of transposable elements and DNA …
