The potential of multispectral imaging flow cytometry

Environmental monitoring involves the quantification of microscopic cells and particles such as algae, plant cells, pollen, or fungal spores. Traditional methods using conventional microscopy require expert knowledge, are time-intensive and not well-suited for automated high throughput. Multispectral imaging flow cytometry (MIFC) allows measurement of up to 5000 particles per second from a fluid suspension and…

What about honey bee jelly?

The increasing loss of honey bee colonies is assumed to be caused by various factors such as habitat degradation, parasites, pathogens, or the exposure to environmental pollutants like pesticides in agriculture practice. Different bee-related products like honey, bee bread, wax, and pollen can be contaminated by pesticides and some of them might affect colony health.…

Impact of a microbial pest control product containing Bacillus thuringiensis

To avoid potential adverse side effects of chemical plant protection products, microbial pest control products (MPCP) are commonly applied as biological alternatives. This study aimed to evaluate the biosafety of a MPCP with the active organism Bacillus thuringiensis ssp. aizawai (strain: ABTS-1857). An in-hive feeding experiment was performed under field-realistic conditions to examine the effect…

Honey bee colony loss rates in 37 countries using the COLOSS survey for winter 2019–2020

Abstract This article presents managed honey bee colony loss rates over winter 2019/20 resulting from using the standardised COLOSS questionnaire in 37 countries. Six countries were from outside Europe, including, for the first time in this series of articles, New Zealand. The 30,491 beekeepers outside New Zealand reported 4.5% of colonies with unsolvable queen problems,…

Fully funded PhD position in evolutionary genomics of insect immunity at the University of Ulm, Germany

Fully funded PhD position in evolutionary genomics of insect immunity at the University of Ulm, Germany. Title: ImmuNov – Genomics and epigenomics of immune innovations in insects. We are recruiting a PhD student to study the evolution of innate immunity in insects. The project involves comparative analysis of the gene expression response (i.e. transcriptomics) of…

Crushing corn pollen grains increased diet digestibility and hemolymph protein content while decreasing honey bee consumption

A honey bee colony’s ability to grow and develop is dependent on adequate nutrition. Bees collect pollen from flowers as a source of protein, fat, vitamins, and minerals. The crude protein content of corn pollen is considered low, around 15%; however, bees frequently visit the male flowers of the tassels for pollen. In this study,…

COLOSS Executive Committee (EC) elections 2022

Dear COLOSS members, According to our statutes, we will democratically elect a new Executive Committee (EC) at our forthcoming General Assembly (GA) associated with the next COLOSS conference. The EC is right at the core of our network. COLOSS can simply not function without it. Therefore, it is crucial that dedicated members interested in actively…
