In many types of applied and fundamental studies involving honeybees, it is necessary to evaluate the populations of adult bees and brood of various ages, as well as assess quantities of nectar, honey, bee bread and pollen. In order to establish how the structure of the colony changes over time, such assessments may be made repeatedly.  ColEval: Honeybee COLony Structure EVALuation for Field Surveys (Hernandes 2020) is a common method for such assessments where reference photographs...

Pollinators play a vital role in maintaining biodiversity and agricultural production worldwide, but they are susceptible to various infectious and parasitic agents (IPAs). To better assess the exposure of honey bees to IPAs, researchers have developed discriminative and quantitative molecular methods. These methods produce large datasets that need to be summarised for interpretation. Graphical abstract of the paper. A new PoshBee paper describes the calculation of three types of...

Since its beginning in 2018, PoshBee has been working on transforming its scientific results into practical recommendations. In that spirit, the project has published a total of 16 practice abstracts on the EIP-AGRI platform presenting the practical implications of its results. These concise pieces of information cover the project's full life cycle, from its objectives (presented in practice abstract 1) to its results. In March 2023, to finalise its collection, the project published two new...

During PoshBee’s final meeting in March 2023, project members were surprised with an unexpected outcome from the project’s semi-field experiments. PoshBee partner Robin Dean prepared a gift bag for everyone with goodies made from PoshBee beeswax. The goodies came with some handy instructions on how to use the wax to create a boot waterproofer, a lip balm or a hand cream. PoshBee beeswax and tealights, wrapped in a compostable cellophane bag and a raffia tie. This was...

Pesticides pose a potential threat to bee health, which could be exacerbated when combined with other stressors, such as parasites. Current pesticide risk assessment however evaluates pesticide impact on otherwise healthy bees without accounting for these additional stressors. To understand the specific impacts of pesticides and their interactions with other stressors, a new PoshBee paper tested acute oral doses of three pesticides — glyphosate, Amistar and sulfoxaflor — on the...
