Gambel Oak Care, Shawn Olsen, Debbie Amundsen, Shital Poudyal
Gambel Oak Care, Shawn Olsen, Debbie Amundsen, Shital Poudyal
All Current Publications
Gambel oak is commonly called scrub oak, but other common names are Rocky Mountain white oak and Utah white oak. The scientific name is Quercus gambelii, after William Gambel, an American naturalist. This fact sheet reviews Gambel oak's usability in the landscape, its care, growth requirements, diseases and pests, and maintenance.
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 …
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 …
Rna Interference And Validation Of Reference Genes For Gene Expression Analyses Using Qpcr In Southern Pine Beetle, Dendroctonus Frontalis, Bethany R. Kyre, Thais B. Rodrigues, Lynne K. Rieske
Rna Interference And Validation Of Reference Genes For Gene Expression Analyses Using Qpcr In Southern Pine Beetle, Dendroctonus Frontalis, Bethany R. Kyre, Thais B. Rodrigues, Lynne K. Rieske
Entomology Faculty Publications
RNA interference (RNAi) is a highly specific gene-silencing mechanism that can cause rapid insect mortality when essential genes are targeted. RNAi is being developed as a tool for integrated pest management of some crop pests. Here we focus on an aggressive forest pest that kills extensive tracts of pine forests, the southern pine beetle (SPB), Dendroctonus frontalis. We sought to identify reference genes for quantitative real-time PCR (qPCR) and validate RNAi responses in SPB by mortality and gene silencing analysis. Using an adult beetle feeding bioassay for oral ingestion of dsRNA, we measured the expression and demonstrated knockdown of …
Bark Beetles, Ryan S. Davis, Darren Mcavoy
Bark Beetles, Ryan S. Davis, Darren Mcavoy
All Current Publications
Bark beetles are one of the most destructive forest pests in the world. They are different than the larger longhorned and roundheaded/metallic woodboring beetles commonly infesting the inner wood of trees. The largest bark beetle, the red turpentine beetle (Dendroctonus valens), reaches only 8.3 mm in length. Because of their tiny size, bark beetles are not effective tree killers as individuals.

50 Years Of Research At The North Platte Experiment Station, W. W. Burr, J. C. Adams
50 Years Of Research At The North Platte Experiment Station, W. W. Burr, J. C. Adams
Nebraska Agricultural Experiment Station: Historical Circulars
The North Platte Experiment was established fifty years ago. So many changes have occurred since then that few people remember why research in dry land agriculture was started in Nebraska and other Great Plains states. In order to get a proper perspective, it may be well to consider some early history.
Fifty Years Of Achievement In Agricultural Investigation, R. T. Prescott
Fifty Years Of Achievement In Agricultural Investigation, R. T. Prescott
Nebraska Agricultural Experiment Station: Historical Circulars
In Nebraska, a hustling frontier state in 1887, the legislature hesitated not at all in taking advantage of the provisions of the Hatch Act, and now that fifty years have elapsed since the Station was founded, seventy-five years since the Land Grant College Act was passed and the U. S. Department of Agriculture established, and almost twenty-five years since the Agricultural Extension Service was added, it seems worth while to present a general summary of achievement within the state. The main object will be to show some of the important things that have been learned through the investigations of the …
