Domestication has changed the chemicals squash flowers use to attract bees

In a new study published in the Journal of Chemical Ecology, a team led by researchers in Penn State’s College of Agricultural Sciences found that domesticated flowers have different scent chemical profiles than wild plants in several species of squash. Additionally, the specialized pollinators of these plants—squash bees—detect different compounds, called floral volatile organic compounds (VOCs) in wild plants that they co-evolved with than in domesticated plants.

College of Ag Sciences awards bridge funding for global research collaborations

Penn State’s College of Agricultural Sciences has awarded bridge funding to four faculty members to support research collaborations addressing soil fertility, public health, climate resilience and agricultural trade include two from the Center for Root and Rhizosphere Biology.

Salty soil, scrappy bugs and shared ideas drive graduate student’s research

Sahil Pawar says that tackling the world’s agricultural challenges is not a task for one person — it requires a collective effort. That grounded view shapes the early-career entomologist’s research, which examines how environmental stressors, such as soil salinity, drought and climate change, influence the interactions between crops and the pests that feed on them.

Spotted lanternfly may use ‘toxic shield’ to fend off bird predators

Spotted lanternflies may season themselves to the distaste of potential bird predators, according to a new study led by entomologists in Penn State’s College of Agricultural Sciences.

Wild lupine genetics could be key to conservation of species

Researchers at Penn State studying declining populations of sundial lupines in the eastern part of the United States are closer to determining how the plant's genetics could be used to inform reseeding strategies to help with conservation efforts of the blue flowering plant.

Gene editing, traditional crossbreeding produce disease-resistant cacao plants

Novel approach could revolutionize sustainable chocolate production while addressing global food security, researchers report.

Organic beekeeping can be even more profitable than conventional methods

Organic beekeeping can support healthy and productive honey bee colonies, and a new study led by researchers in Penn State’s College of Agricultural Sciences found that adopting organic honey bee colony management is not only profitable, but in some cases, it can be even more profitable than conventional management.

Study offers new insight into mixed virus interactions in plants

New research led by researchers at Penn State examined what happens when two common viruses — tomato spotted wilt orthotospovirus (TSWV) and impatiens necrotic spot orthotospovirus (INSV) — infect the same plant.
