Several parasites and pathogens that devastate honeybees in Europe, Asia and the United States are spreading across East Africa, but do not appear to be impacting native honeybee populations at this time, according to an international team of researchers.
A study of the spread of chronic wasting disease among white-tailed deer in Virginia, West Virginia, Maryland and Pennsylvania found that infected deer tend to cluster in low-lying open and developed areas. These results suggest that state wildlife management agencies should concentrate surveillance efforts in such topography and landscapes, according to researchers in Penn State's College of Agricultural Sciences.
Scientists in the Center for Pollinator Research at Penn State received three grants from the U.S. Department of Agriculture and the National Science Foundation to study various threats to honey bees, including disease, pesticides and the extinction and invasion of other species into their habitats.
Mice on a high-fat diet that consumed decaffeinated green tea extract and exercised regularly experienced sharp reductions in final body weight and significant improvements in health, according to researchers in Penn State's College of Agricultural Sciences, who suggest that similar results could be realized by people.
Sensory technologists at Penn State use a range of information technologies to study the science of personal taste.
Stigmatization may have once served to protect early humans from infectious diseases, but that strategy may do more harm than good for modern humans, according to Penn State researchers.
A local startup’s Big Idea has won $25,000 from Ben Franklin Technology Partners. Nina Jenkins with Penn State’s Department of Entomology and her business partner, Giovani Bellicanta, have developed a patent-pending, nontoxic, bio-pesticide that successfully removes and further prevents bed bug infestations in homes and hotel rooms.
Mark Brennan, professor of leadership and community development in the College of Agricultural Sciences, and Jane Reese, assistant coordinator of the Penn State Hubert H. Humphrey Fellowship Program, are recipients of the 2014 W. LaMarr Kopp International Achievement Award. Established in 1995, the award recognizes faculty and staff members who have contributed significantly to the advancement of the international mission of the University. It is named for the late deputy vice president for international programs.
Six Penn State faculty members have received the 2014 George W. Atherton Award for Excellence in Teaching. They are Meredith Defelice, senior lecturer of biochemistry and molecular biology in the Eberly College of Science; Michael Evans, assistant chief academic officer and instructor of nursing at Penn State Worthington Scranton; Karen Kackley-Dutt, instructor of biology at Penn State Lehigh Valley; Dale Olver, instructor of dairy and animal science in the College of Agricultural Sciences; Ute Poerschke, associate professor of architecture in the College of Arts and Architecture, and Jessica Schocker, assistant professor of social studies education and women’s studies at Penn State Berks. The award, named after Penn State’s seventh president, honors excellence in teaching at the undergraduate level.
Paige Castellanos, a doctoral candidate in rural sociology and international agriculture and development in the College of Agricultural Sciences, has been honored as the recipient of the 2014 W. LaMarr Kopp International Achievement Award for graduate students.
Planting cover crops in rotation between cash crops -- widely agreed to be ecologically beneficial -- is even more valuable than previously thought, according to a team of agronomists, entomologists, agroecologists, horticulturists and biogeochemists from Penn State's College of Agricultural Sciences.
As the dust settles on February's enactment of the 2014 farm bill, experts continue to analyze the bill's provisions to determine what the legislation means for farmers. An economist in Penn State's College of Agricultural Sciences says the bill's dairy provisions -- the aspect of federal farm policy arguably most important for Pennsylvania agriculture -- continue the shift toward a greater reliance on risk-management approaches to provide a safety net for farmers.
Dairy cows in barn An estimated 18 percent of greenhouse gas emissions worldwide come from animal production. A Penn State-led consortium will seek to develop feeding strategies that will reduce methane and nitrous oxide emissions from livestock.
The restoration of Pennsylvania's river-otter population has been, by all accounts, a great success, and a study being conducted by researchers in Penn State's College of Agricultural Sciences will soon quantify the accomplishment by yielding population information.
Brown marmorated stink bugs cause millions of dollars in crop losses across the United States because of the damage their saliva does to plant tissues. Researchers at Penn State have developed methods to extract the insect saliva and identify the major protein components, which could lead to new pest control approaches.
The environment significantly influences whether or not a certain bacterium will block mosquitoes from transmitting malaria, according to researchers at Penn State.
Female Asian longhorned beetles lure males to their locations by laying down sex-specific pheromone trails on tree surfaces, according to an international team of researchers. The finding could lead to the development of a tool to manage this invasive pest that affects about 25 tree species in the United States.
Farmers should take extra precautions so drifting herbicides do not create unintended consequences on neighboring fields and farms, according to agricultural researchers.
Aggression-causing genes appeared early in animal evolution and have maintained their roles for millions of years and across many species, even though animal aggression today varies widely from territorial fighting to setting up social hierarchies, according to researchers from Iowa State University, Penn State and Grand Valley State University.
The Penn State Department of Entomology is seeking undergraduate student applicants for the Dutch Gold Honey Scholarship for honey bee research.
