The Role of Pathogens in Bumblebee Decline: A Review.
Pathogens

Biology Department, University of Massachusetts Boston, Boston, MA 02125, USA.
Bumblebees, the most important wild pollinators in both agricultural and natural ecosystems, are declining worldwide. The global decline of bumblebees may threaten biodiversity, pollination services, and, ultimately, agricultural productivity. Several factors, including pesticide usage, climate change, habitat loss, and species invasion, have been documented in the decline of bumblebee species, but recent studies have revealed the dominating role of pathogens and parasites over any of these causes.

The increasing prevalence of monocultures has reduced floral diversity, diminishing pollen diet variety for bees. This study examines the impact of monofloral pollen diets (hazel, rapeseed, pine, buckwheat, , goldenrod) on the antioxidant enzyme activities in the fat body from tergite 3, tergite 5, sternite, and hemolymph of honey bees. We show that pollen from plants such as rapeseed, , buckwheat, and goldenrod (rich in phenolic compounds and flavonoids) increases the activities of SOD, CAT, GST, and GPx in the fat body and hemolymph compared to the control group.

Bee venom (BV) represents a promising natural alternative to conventional antibiotics, particularly significant given its broad-spectrum antimicrobial activity and potential to address the growing challenge of antimicrobial resistance. The prevalence of antimicrobial-resistant microorganisms (AMR) is a global burden that affects human health and the economies of different countries. As a result, several scientific communities around the world are searching for safe alternatives to antibiotics.

South Korea's beekeeping industry has been facing a major crisis due to colony collapse disorder (CCD), manifesting since the winter of 2021. CCD in South Korea is presumed to be caused by a combination of factors, including an abnormal climate, pesticide use, declining source plants, and increased honey bee diseases. We examined the prevalence of 12 major honey bee () pathogens by sampling 3,707 colonies with abnormal behavior and suspected pathogen infections from 1,378 apiaries nationwide between 2020 and 2023.
