Chronic in‑hive exposure to a field‑relevant concentration of Closer™ SC (24% sulfoxaflor) insecticide altered immunological and physiological markers of honey bee foragers (Apis mellifera)

Articles

Sulfoxaflor (SULF), a well-known alternative for the banned neonicotinoids, is not environmentally persistent, yet numerous studies using field-realistic levels have demonstrated its detrimental impact on honey bee colonies. Despite this, even just a limited number of studies have addressed its residue-level effects on the physiological and immunological biomarkers of foraging honey bees in semi-field conditions.…

Chronic exposure to a field‑realistic concentration of Closer® SC (24% sulfoxaflor) insecticide impacted the growth and foraging activity of honey bee colonies

Articles

The effects of sulfoxaflor on various pollinators have long been debated. However, there have been few in-hive studies on sulfoximines, and the effects on honey bee colony growth and foraging activity are unknown. Here, we calculated the LC50 of Closer® 24% suspension concentrate (SC) using honey bee foragers and then assessed the impacts of chronic…

Long-term field-realistic exposure to a next-generation pesticide, flupyradifurone, impairs honey bee behaviour and survival

Articles

Abstract: Simone Tos, James C. Nieh, Annely Brandt, Monica Colli, Julie Fourrier, Herve Giffard, Javier Hernández-López, Valeria Malagnini, Geoffrey R. Williams, Noa Simon-Delso The assessment of pesticide risks to insect pollinators have typically focused on short-term, lethal impacts. The environmental ramifications of many of the world’s most commonly employed pesticides, such as those exhibiting systemic…

The threat of veterinary medicinal products and biocides on pollinators: A One Health perspective

Articles

Abstract The One Health approach acknowledges that human health is firmly linked to animal and environmental health. It involves using animals such as bees and other pollinators as sentinels for environmental contamination or biological indicators. Beekeepers noticed intoxications of apiaries located in the vicinity of sheep and cattle farms, which led to the suspicion of…
