Penn State centers collaborate on pollinator education project

A recently awarded USDA grant will allow CPR researchers and Center for Science and the Schools partners to partner with elementary school teachers in Pennsylvania to develop cross-disciplinary curricula that support students in understanding pollinator research in the areas of food, agriculture and natural resources.

USDA grant to support expansion of online tool for bee conservation

A Penn State-led research team has received a nearly $950,000 U.S. Department of Agriculture grant to create the next generation of an online decision-support tool designed to help conserve pollinator populations across the United States.

Undergraduate Research Award Funds Pollinator Photo Project

Darya Alvarez completed a photography project funded by an Apes Valentes Undergraduate Research Award. Her goal is to help viewers gain a greater appreciation of the critical role that bees play in the survival of terrestrial ecosystems.

The business of bees

The economic value of insect pollination services is much higher than previously thought in the U.S., new research finds.

Penn State entomologists devise a system to control mushroom phorid flies

Working with producers, researchers develop method to give beleaguered residents relief from pest

Summer weather conditions influence winter survival of honey bees

Winter survival of honey bee colonies is strongly influenced by summer temperatures and precipitation in the prior year, according to Penn State researchers, who said their findings suggest that honey bees have a "goldilocks" preferred range of summer conditions outside of which their probability of surviving the winter falls.

Grozinger receives National Academy's Prize in Food and Agriculture Sciences

Christina Grozinger, Publius Vergilius Maro Professor of Entomology in Penn State's College of Agricultural Sciences, will be honored by the National Academy of Sciences for helping the world understand how to address the crisis of global declines in pollinator populations.

Feral colonies provide clues for enhancing honey bee tolerance to pathogens

Understanding the genetic and environmental factors that enable some feral honey bee colonies to tolerate pathogens and survive the winter in the absence of beekeeping management may help lead to breeding stocks that would enhance survival of managed colonies, according to a study led by researchers in Penn State's College of Agricultural Sciences.

Climate change reduces the abundance and diversity of wild bees, study finds

Wild bees are more affected by climate change than by disturbances to their habitats, according to a team of researchers led by Penn State. The findings suggest that addressing land-use issues alone will not be sufficient to protecting these important pollinators.
