Microsporidia from the Nosema (Vairimorpha) genus are pathogenic fungi that complete their life cycle in the honeybee intestine. Therefore, the aim of this study was to determine the impact of the course of infection on the viability of honeybee intestine cells. Methods and Results: Intestines isolated from healthy and N. ceranae-infected honeybees were stained using…
The rapid increase in global plastic production and usage has led to global environmental contamination, with microplastics (MPs) emerging as a significant concern. Pollinators provide a crucial ecological service, while bee populations have been declining in recent years, and MPs have been recognized as a new risk factor contributing to their losses. Despite the pervasive…
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.…
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…
The Department of Agroecology at Aarhus University, Denmark, offers an attractive career opportunity for promising and talented researchers from around the world. We invite applications for a position as Tenure Track Assistant Professor focusing on agricultural entomology and pollination ecology to spearhead research in pollination in agricultural systems. Research topics could include but are not…
The EU Pollinator Week is an event bringing together experts, policymakers, and stakeholders. This year’s theme is “A New Deal for Pollinators”, emphasising the current status and future opportunities to secure the fundamental role of pollinators. The event will be held online, and registration is now open. Browse the schedule and register for the sessions…
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…
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…
