Poplar Borer, Marion Murray, Ryan Davis
Poplar Borer, Marion Murray, Ryan Davis
All Current Publications
The poplar borer is the most commonly submitted wood borer found in aspens and other poplars in Utah. While large trees are seldom killed by this pest, it can cause the decline of trees, weakening of branches or the bole (which promotes wind breakage), and allows the introduction of pathogens. This fact sheet describes poplar borer life cycle, damage, and control.

Interdisciplinary Team Addresses Cotton Leafroll Dwarf Virus In Alabama, Kassie N. Conner, Edward Sikora, Jenny Koebernick, Marcio Zaccaron
Interdisciplinary Team Addresses Cotton Leafroll Dwarf Virus In Alabama, Kassie N. Conner, Edward Sikora, Jenny Koebernick, Marcio Zaccaron
The Journal of Extension
A multi-state and interdisciplinary team was formed to address the Extension and research needs of CLRDV, an emerging cotton disease with high potential impact for U.S. cotton production. In 2017, CLRDV was identified in AL and Auburn University immediately formed an interdisciplinary working group composed of plant breeders, plant pathologists, entomologists, and agronomists. Since then, scientists from ten other states have joined the CLRDV group. Thus, allowing research to be coordinated efficiently and best deploy limited resources to attend the stakeholder’s needs. The CLRDV group produces and shares new and relevant information with the scientific community and cotton producers alike.
Conservation And Variation In Agricultural Landscapes: A Survey Of Insect Populations Across Naranjilla Cultivation Methods In The Eastern Andean Cloud Forest, Ian Zakelj
Independent Study Project (ISP) Collection
This study compared insect biodiversity among five sites in agricultural landscapes and natural forest in the El Placer community in the valley of the Rio Pastaza in the eastern Andean cloud forest. The area is of vital importance to conservation, as it falls in the ecological corridor between the Sangay and Llanganates national parks. The primary crop produced by the residents of El Placer is naranjilla, and it is cultivated in a variety of manners, mostly with intensive chemical use. The goal of the study was to find out which types of practices were the least harmful to the insect …
How Weeds Affect Insects In Mango Cultivation Of South Florida, Blaire Kleiman
How Weeds Affect Insects In Mango Cultivation Of South Florida, Blaire Kleiman
FIU Electronic Theses and Dissertations
The use of weeds as insectary plants is an emerging management tactic by agroecologists and entomologists to sustain beneficial insect species. Fallow lands have always been used by insects and are an important part of their diet in fragmented ecosystems. Weeds provide floral resources to beneficial insects such as pollinators, parasitoids, and predators and resources to keep them within a field in between crop flowering. Using weeds as a tool in tropical fruit production reliant on pollination like Mango (Mangifera indica) allows farmers to reduce herbicide use, increases the biodiversity of both plants and insects, and increases pollination of crops …

Examining The Efficacy Of Cover Crops As An Integrated Pest Management Tool In Organic Farms In The Lower Rio Grande Valley, Lili M. Martinez
Examining The Efficacy Of Cover Crops As An Integrated Pest Management Tool In Organic Farms In The Lower Rio Grande Valley, Lili M. Martinez
Theses and Dissertations
The Lower Rio Grande Valley (LRGV) consists of a mix in subtropical and costal habitats, a combination that provides a favorable environment for the animals and plants that inhabit it. This is a problem for organic farmers as they refrain from using synthetic chemicals and therefore led them to seek other methods of dealing with insect herbivory. Of the many alternative methods available, we looked specifically at integrated pest management methods (IPM) to determine their efficacy in reducing insect herbivory among cash crops. Chapter II discusses an experiment performed in an organic farm in Edinburg, Texas consisting of a two-year …
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 …
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.

Effectiveness Of Different Agricultural Management Styles As Insect Biological Corridors: A Comparison Of Insect Populations In Fragmented Chocó Cloud Forest, Ecuador, Tara M. Krantz
Independent Study Project (ISP) Collection
Insects are part of the most diverse class of animals on the planet and are essential to various ecological functions such as pollination, nutrient cycling, providing a food source for other taxa, and more. The diversity and ecological services of insects are necessary to the operation of agriculture because of pest control and pollination of crops. However, the diversity of insects is severely reduced due to fragmentation. It is currently not well understood if certain types of agriculture can lessen the impact of fragmentation on natural and crop-based insect communities. In this study, insect populations in four different agricultural management …

The Role Of Disease & Insects In Aspen Ecology, John C. Guyon Ii
The Role Of Disease & Insects In Aspen Ecology, John C. Guyon Ii
Aspen Bibliography
Aspen is a keystone species in montane forests, and enhances a number of key resource values including wildlife habitat, water resources, and fire behavior. Recently, aspen forests have experienced episodes of dieback and decline across western North America (Worrall et al. 2010, Guyon and Hoffman 2011). A large proportion of the dieback and decline has been linked to drought stress or drought-prone locations (Hanna and Kulakowski 2012). However, insects and diseases are commonly found in declining aspen stands, leading to confusion about the role of insects and diseases in aspen ecology. Additionally, aspen has a reputation for being susceptible to …

Clover Root Curculio (Sitona Hispidulus F.), Kaitlin Rim, Steven Price, Ricardo Ramirez
Clover Root Curculio (Sitona Hispidulus F.), Kaitlin Rim, Steven Price, Ricardo Ramirez
All Current Publications
The clover root curculio is an important agricultural pest in forage production systems. Adult beetles feed on the host plant leaves while the damaging larval stage feeds on the roots below ground. Heavy larval feeding has been associated with reduced stand establishment, disruption of nutrient and water uptake, increased secondary plant pathogen infection, decreased winter plant survival, delayed green-up, and reductions in forage quality and yield. Due to the hidden nature of eggs and larvae in the soil, CRC has been overlooked and damage is often misdiagnosed as nutrient deficiencies or pathogens. Historically, applications of chlorinated hydrocarbons, carbamates, and organophosphates …
