Urban Agriculture Focus Of Author Presentation, Lawrence University

Press Releases

Award-winning Canadian food journalist Jennifer Cockrall-King discusses alternative food systems in a Lawrence University presentation Monday, April 22 at 7 p.m. in Thomas Steitz Hall of Science Room 102. Cockrall-King’s appearance, sponsored by Lawrence’s Spoerl Lecture in Science and Society, is free and open to the public.

Based on her book “Food and the City: Urban Agriculture and the New Food Revolution,” the address examines food systems in cities around the world that are shortening their food chains by utilizing community gardens, collective orchards and vertical farms within their city limits and taking “food security” into their own hands.

Characterization Of Resistance To The Cry1f Toxin From Bacillus Thuringiensis In Resistant Fall Armyworm, Spodoptera Frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) From Puerto Rico, Ana Maria Velez

Department of Entomology: Dissertations, Theses, and Student Research

Transgenic corn expressing Cry1F protein from Bacillus thuringiensis Berliner has been registered for Spodoptera frugiperda control since 2003. Unexpected damage to Cry1F corn was reported in 2006 in Puerto Rico and Cry1F resistance in S. frugiperda was documented. The inheritance of Cry1F resistance was characterized in a S. frugiperda resistant strain from Puerto Rico which displayed >387-fold resistance to Cry1F. Concentration-response bioassays of reciprocal crosses of resistant and susceptible parental populations indicated that resistance is recessive and autosomal. Bioassays of the backcross of the F₁ generation crossed with the resistant parental strain suggest that a single locus is responsible …

Assessment Of Tillage Practices Using Landsat-Tm 5 In Nebraska., Sonisa Sharma

School of Natural Resources: Dissertations, Theses, and Student Research

Tillage management practices are an important component to crop production and to federal and state conservation efforts and crop subsidy programs. Crop residue created by conservation tillage reduces soil erosion and reduce evaporation from exposed soil. Agro-hydrological models require information on tillage practices to estimate their impacts on soil-water-holding capacity, total evapotranspiration, carbon sequestration, water runoff and water and wind erosion for agricultural lands. Classification of tillage practices using remote sensing offers promise for the rapid collection of tillage information on individual fields over large areas. Using satellite imagery proves to be challenging due to the similarity in spectral signatures …

New Technologies For Studying Crops And Crop Diseases, Dennis O’Brien

Agricultural Research Magazine

Agricultural Research Service scientists in New York and California have developed very different technologies that share a common thread. They offer scientists new, innovative ways to probe what happens when a crop is threatened by drought or disease.

Michelle Cilia and Stewart Gray, ARS scientists at the Robert W. Holley Center for Agriculture and Health in Ithaca, New York, and their colleagues at the University of Washington have found a way to map the structure of an elusive protein that gives certain plant viruses the ability to travel from plants to insects, through the insects, and back into plants.

New Discovery Makes Detecting Johne's Disease Easier, John Bannantine, Sandra Avant

Agricultural Research Magazine

Before a disease can be treated, it must first be identified. But that’s not always easy, especially in the case of Johne’s disease, which affects cattle, sheep, goats, deer, and other ruminants.

Johne’s disease—also known as “paratuberculosis”— is a costly, contagious disease that causes diarrhea, reduced feed intake, weight loss, and sometimes death. Annual estimated losses to cattle producers range from $40 to $227 per infected animal. For the U.S. dairy industry alone, losses exceed $220 million each year.

For years, scientists have been hampered by the fact that any antibody—a protein produced by the immune system to fight infections …

House Fly Virus Stops, Christopher J. Geden, Sandra Avant

Agricultural Research Magazine

The house fly is often considered merely a nuisance. But these flies are capable of transmitting animal and human pathogens that can lead to foodborne diseases, including Escherichia coli, Salmonella, and Shigella bacteria.

Insecticides are important for control, but house flies are particularly good at developing resistance, and their larvae tend to stay deep enough within their gooey food to avoid exposure to sprays.

Scientists at the Agricultural Research Service’s Center for Medical, Agricultural, and Veterinary Entomology (CMAVE) in Gainesville, Florida, are looking at new methods that target adult flies. A promising biological control agent—salivary gland hypertrophy virus …

Challenge For Sustaining Agriculture, Mark Walbridge

Agricultural Research Magazine

With the climate changing and the world’s population expected to rise in the coming decades, supplying a hungry planet with food and fiber will become more of a challenge. By some estimates, food production will have to increase by up to 70 percent to feed the world over the next 40 years. Perhaps no resource is more critical to meeting that challenge than water.

How essential is water to agriculture? An estimated 17 percent of all harvested U.S. cropland is irrigated, accounting for about 56.6 million acres. Worldwide, more than 40 percent of the world’s food is grown on irrigated …

Rooting Out A Novel Stress Syndrome In Pigs, Dan Nonneman, Sandra Avant

Agricultural Research Magazine

Undergoing surgery, even a minor procedure, can be stressful for anyone. But for people who have malignant hyperthermia, a hereditary disease that’s triggered by certain drugs used for general anesthesia, it can also be dangerous.

Research into this rare, life-threatening condition, which causes a fast rise in body temperature, severe muscle contractions, and sometimes death, was limited until the discovery of a similar disorder in pigs, referred to as “porcine stress syndrome.” The classical syndrome is associated with poor response to stressors like transport and with poor-quality pork. It has been eliminated from commercial herds in the United States, but …
