PoshBee just published a new video on YouTube! In the training video "PoshBee Research: Pesticide risk assessment experiments on wild bee species", Alexandre Barraud, a PhD student from the University of Mons, will not talk about domesticated bee species, but rather about wild bee species. Which, even if you may not always see them, represent over 20 000 species in Europe. These species can be very different in terms of size or colours. They can be solitary or social, they can...

PoshBee just published a new video on YouTube! In the training video "PoshBee Research: Effects of agrochemical-nutrition interactions on bee health in the laboratory", Alexandre Barraud, a PhD student from the University of Mons, gives more insight into bee decline in Europe. It is a fact that several bee species, including crop pollinating species, are currently in decline. Bumblebees, for example, are an important pollinator group, but about one-third of the species is in...

Consortium members, practitioners and other stakeholders of the PoshBee project met up between 11 and 13 January 2022 for the project’s fourth annual general meeting. The three-day-long event hosted by the coordinating institution Royal Holloway, University of London was marked by insightful presentations, vivid discussions and an overview of the project’s developments and future initiatives. The initial format in mind of the meeting was a hybrid conference environment, with five...

MALDI IMS (matrix-assisted laser desorption/ionization imaging mass spectrometry) is a powerful technology used to investigate the spatio-temporal distribution of a huge number of molecules throughout a body/tissue section. Like in other animal models, imaging approaches such as this one could be used to assess the impact of health stressors on honeybees. In order to better understand the perspectives of such approaches, a recent PoshBee research paper reported on how MALDI IMS can be employed...

In order to facilitate semi-field and field experiments on honey bees, PoshBee partners proposed a novel integrated system of research equipment.  Study Frame. The system’s main component is the Study Frame (Figure 1). It is constructed so that one or both sides can be fitted with a queen excluder cover held in place with clips. Each side of the top bar is laser-engraved with a unique identifier. Converter Hive. The second important item is the Converter Hive...

Beebread is an essential food source for honeybees, bumblebees and solitary bees, which store pollen in their nests. However, this pollen can often be contaminated by pesticides, which also affects the beebread. As a result, contaminated beebread is amongst the main sources of dietary exposure to pesticides across all bee species. Nevertheless, it is still insufficiently analysed despite its ability to store pesticides for long periods of time. Flying bees. In this context, a recent...

A new research article published in the open-access online journal Nature Ecology & Evolution presents insightful ways to improve the pesticide-use data for the European Union. Photo courtesy: @franki/unsplash.com Access to pesticide-use data is important to properly assess the harmful effects of pesticides on human and ecosystem health. That is why the European Commission has proposed to reform the EU legal framework of statistics on agricultural input and output in February...

No evidence that Glyphosate alone, or in combination with a common parasite, has negative lethal or sublethal effects on bumble bees Glyphosate is the most commonly used pesticide in the world, and is widely used in agriculture. While glyphosate has been deemed ‘bee-safe’ by regulators, some emerging evidence studies suggest that it has negative effects on bees. For that reason, discovering whether glyphosate alone, or in combination with other stressors, is detrimental to bee...

In this PoshBee video project partners from BioPark Archamps and CNRS demonstrate the analysis of bee haemolymph samples with MALDI BeeTyping®. They perform spectral analysis, with the conclusions reached through this method being of significant importance for gaining in-epth knowledge about beehealth.

This PoshBee training video titled "PoshBee research: Nectar extraction from bees" was created by PoshBee researchers from ANSES. The video demonstrates the PoshBee methods for nectar extraction from bee stomachs performed by the PoshBee researchers at the ANSES Sophia Antipolis laboratory.

A research article recently published in the Environmental International journal provides insight into the effects that the exposure to the product Closer containing the insecticide sulfoxaflor and the product Amistar containing the fungicide azoxystrobin has on bumble bees. The article called "Fungicide and insecticide exposure adversely impacts bumble bees and pollination services under semi-field conditions" shows that Closer (sulfoxaflor insecticide) led to reduced colony...

Pollinators are suffering declines worldwide, and pesticides are thought to be the main driver of their decline. In this context, a lot of research effort has been put into understanding and regulating the active ingredients in pesticides. Nevertheless, the additional components in pesticide formulations are often overlooked and understudied. Bumblebee on a flower. To make up for this oversight, a new PoshBee research article, called Co‐formulant in a commercial fungicide...

A new PoshBee video titled "PoshBee research: The PoshBee database" demonstrates the digital data storage platform Poshbase, which serves for gathering and exchange of data between researchers. The video is part of a new PoshBee video series which displays various research techniques and methods used by project researchers, including measuring chemical exposure, pathogens and nutrition in honey bees, bumblebees, and solitary bees. The researchers from the Anses Sophia-Antipolis...

The PoshBee project was presented at the 2021 edition of the EU Pollinator Week which took place online between 27-30 September. Project partner Dr. Dalel Askri of BioPark Archamps participated in the European Research Projects: Monitoring Pollinators and Their Stressors session, which focused on the overview of some of the EU research projects gathering data of the status of EU pollinators or the stressing factors that can affect them, such as environmental pollutants, pathogens,...

In an effort to increase the project’s visibility and improve the dissemination of all publicly available project outputs, PoshBee has recently launched an open research collection in the Research Ideas and Outcomes (RIO) journal. The PoshBee Project Outcomes collection in RIO aims to broaden the outreach of project results by publishing not only standard scientific articles, but also other pieces, covering the entire research cycle in a comprehensive manner. The collection  will...

A research article recently published in the British Ecological Society’s Functional Ecology journal, examines how the quantity of floral resources affects pollinator activity and how this relates to the structure and robustness of pollination networks. The paper titled "Patterns of pollination interactions at community-level are related to the type and quantity of floral resources" focuses on the relationship between quantity of floral resources and the number of flower visits...
