Search results for pollinator food

Pollination is vital for many plants, and nutrients present in the soil before these plants even sprout may affect how attractive they eventually are to pollinators, according to Penn State-led research.

A new study led by Penn State found that the squash bee (Eucera pruinosa) has evolved in response to intensifying agriculture — namely squashes in the genus Curcurbita. The research is the first to demonstrate the role of agriculture as an evolutionary force acting on a wild insect pollinator and may have implications for food security.

Neonicotinoid insecticides used to control spotted lanternflies have the potential to harm pollinators, but the degree of risk depends on multiple factors, such as application timing, type of neonicotinoid, the species of tree being treated and pollinator species sensitivity, according to entomologists at Penn State.

Bumble bees found in low-quality landscapes — characterized by a relative lack of spring flowers and quality nesting habitat — had higher levels of disease pathogens, as did bumble bees in areas with higher numbers of managed honey bee hives, according to research led by Penn State scientists.

U.S. college students’ knowledge of bees focuses primarily on honey bees and pollination services, according to Penn State researchers, who said findings from their recent study could help in designing campaigns to generate support for protecting threatened pollinators.

Bees are a highly diverse group of pollinators. There are over 20,000 species of bees worldwide, 4,500 in North America, and 437 in Pennsylvania alone. Despite this variety, when people think of bees their minds tend to go to the image of a cute little honey bee living in a huge hive. However, that is not always the case. In this webinar, Dr. Margarita López-Uribe, Assistant Professor of Entomology and an Evolutionary Ecologist dispels two big myths about bees, discusses how human activity has impacted bees throughout their life cycle and provides guidance for how to make our gardens and landscape better for 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.
