There are around 4,000 bee species in the US and over 400 in Pennsylvania (Figure 1). With so many species it’s very difficult to know what’s going on with each species and any collection of species that co-occur at any given location. There’s growing concern that bees are declining because of a variety of stressors such as habitat loss, pesticides, invasive species, and climate change. While there is good evidence that some bumble bee species

The impact of climate change on plant-pollinator interactions This International Research Experiences for Students (IRES) program will provide undergraduate students with an eight-week international research experience working with mentors from Penn State and Universidad Militar Nueva Granada in Colombia. Projects will focus on studying how environmental factors impact plant-pollinator interactions in mountain ecosystems. Students will participate in interdisciplinary research guided by mentors representing entomology, ecology, engineering, and climate science. Students will receive $4,000 for their

Varroa mites are, without a doubt, one of the most difficult challenges for beekeeping management. Treating for mites is tricky: if you don’t treat for mites the probability of colony survival decreases by ≥55%, but if you overtreat mites may evolve resistance to treatments or there can be negative side effects for the bees. Thus, our general recommendation for beekeepers is to treat mites only when colonies are above threshold while using the least toxic,

Pathogen transmission from honey bees to wild bees has been attributed as one of the major negative impacts that managed honey bees have on wild bee populations. Among the many pests and pathogens that attack honey bees, the varroa mite and its associated virus, deformed wing virus (DWV), are most abundant and detrimental to honey bee health. The synergistic interactions between this virus and varroa mites have increased the amount of DWV in honey bees
