A core set of genes involved in the responses of honey bees to multiple diseases caused by viruses and parasites has been identified by an international team of researchers. The findings provide a better-defined starting point for future studies of honey-bee health, and may help scientists and beekeepers breed honey bees that are more resilient to stress.
A chemical that is thought to be safe and is, therefore, widely used on crops — such as almonds, wine grapes and tree fruits — to boost the performance of pesticides, makes honey bee larvae significantly more susceptible to a deadly virus, according to researchers at Penn State and the U.S. Department of Agriculture.
This year -- for the first time -- Penn State Health entered its own honey in the annual Pennsylvania State Farm Show apiary contest.
What does the study of honey bees have to do with pollen variations and seasonal allergies? Science major Cassandra Darnell hopes to find out through an ongoing independent study she is conducting on the honey bees that she brought to Penn State Berks.
New at the Yard and Garden area at Penn State's Ag Progress Days, Aug. 16-18, visitors can learn about growing garlic, as well as flower arranging, growing herbs, square-foot gardening, hydroponics, pollinators and creating habitat for bees and butterflies, high-tunnels, potato varieties -- and have their questions about gardening answered by experts.
While Penn State has developed a reputation as a leader in pollinator research, the experiences of entomology alumni illustrate another key contribution to pollinator health. Penn State is playing a critical role in training the next generation of scientists to address problems — such as parasitic mites, diseases and pesticide effects — that are likely to take longer to solve than the duration of a research grant or even an entomologist's entire career.
Christina Grozinger, professor of entomology in the College of Agricultural Sciences, has been named a distinguished professor by Penn State, and she also has been chosen to receive the college's 2016 Alex and Jessie C. Black Award for Excellence in Research.
Using modern genetic approaches, a team of researchers has provided strong support for the long-standing, but hotly debated, evolutionary theory of kin selection, which suggests that altruistic behavior occurs as a way to pass genes to the next generation.
Dicamba herbicide drift onto plants growing adjacent to farm fields causes significant delays in flowering, as well as reduced flowering, of those plants, and results in decreased visitation by honey bees, according to researchers at Penn State and the Pennsylvania Association for Sustainable Agriculture.
A new Penn State project aimed at improving the food system in East Africa by enhancing pollination services and promoting bee-derived products has received a Food Systems Innovation Grant from the Global Center for Food Systems Innovation, based at Michigan State University.
Honey bees use different sets of genes, regulated by two distinct mechanisms, to fight off viruses, bacteria and gut parasites, according to researchers at Penn State and the Georgia Institute of Technology. The findings may help scientists develop honey bee treatments that are tailored to specific types of infections.
Feeding honey bees a natural diet of pollen makes them significantly more resistant to pesticides than feeding them an artificial diet, according to a team of researchers, who also found that pesticide exposure causes changes in expression of genes that are sensitive to diet and nutrition.
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 honeybees, including disease, pesticides and the extinction and invasion of other species into their habitats.
The garden demonstration plots at Penn State's Ag Progress Days, Aug. 17-19 at Rock Springs, will be abuzz this year not just with gardeners championing the importance of pollinators, but with many of the actual pollinators themselves, drawn to the vicinity by the specialized plantings designed to do just that.
Whether you are a seasoned gardener or a novice green thumb, you can join the fight to save the honeybees by planting your own pollinator-friendly garden this spring, according to a horticulture specialist in Penn State's College of Agricultural Sciences.
