Article
Full-text available
The ongoing debate about glyphosate-based herbicides (GBH) and their implications for beneficial arthropods gives rise to controversy. This research was carried out to cover possible sublethal GBH effects on the brood and colony development, adult survival, and overwintering success of honey bees (Apis mellifera L.) under field conditions. Residues...
Article
Full-text available
For nearly 100 years, electronic bee counters have been developed using various technologies to track the foraging activity of mostly honey bee colonies. These counters should enable remote monitoring of the hives without disturbing natural flight behaviour while generating precise scientific data. However, there are few counters on the market that...
Article
Automated bee counters advanced over the last hundred years and became increasingly diverse. However, to date, there is no method for standardized validation of counting accuracy and thus no reliable data on daily bee losses, or background mortality in colonies. However, such data are in urgent need by regulators to establish future guidelines for...
Article
Full-text available
Since the EU banned the three neonicotinoid insecticides imidacloprid, clothianidin (CLO) and thiamethoxam (TMX) in 2018, they can still be used if an EU Member State issues an emergency approval. Such an approval went into effect in 2021 for TMX‐coated sugar beet seeds in Germany. Usually, this crop is harvested before flowering without exposing n...
Article
Full-text available
Varroa mites are highly attracted to drone brood of honey bees (Apis mellifera), as it increases their chance of successful reproduction. Therefore, drone brood removal with trap frames is common practice among beekeepers in Europe and part of sustainable varroa control. However, it is considered labour-intensive, and there are doubts about the eff...

As part of the agricultural landscape, non-target organisms, such as bees, may be exposed to a cocktail of agrochemicals including insecticides and spray adjuvants like organosilicone surfactants (OSS). While the risks of insecticides are evaluated extensively in their approval process, in most parts of the world however, authorization of adjuvants...
Article
Full-text available
Pollen is known to be the only source of proteins and fats for honey bees. Therefore, it is an important component of nutrition, essential for brood care and a good indicator for the availability of resources in a landscape. It is also known that a diverse diet is beneficial for bee health, also in relation to winter losses. In this work, an app is...
Article
Full-text available
The BEEHAVE model simulates the population dynamics and foraging activity of a single honey bee colony (Apis mellifera) in great detail. Although it still makes numerous simplifying assumptions, it appears to capture a wide range of empirical observations. It could, therefore, in principle, also be used as a tool in beekeeper education, as it allow...
Article
Full-text available
Currently, more than 360 spray adjuvants are registered in Germany (September 2021). Unlike plant protection products (PPPs), adjuvants are not subjected to regulatory risk assessment. In practice, numerous combinations of PPPs and adjuvants are therefore possible. Thus, tank mixtures containing insecticides that are classified as non-hazardous to...

In this work, a functional prototype of the BeeCheck counting device was evaluated for its accuracy to validate its suitability for scientific purposes. Two different approaches were applied: (i) we manually compared electronic data of the counting device by video recordings of entry and exit events, and (ii) by using the so-called "robber's test"...

In the last decade, the use of neonicotinoid insecticides increased significantly in the agricultural landscape and they are meanwhile considered a risk to honey bees. Besides the exposure to pesticides, colonies are treated frequently with various acaricides that beekeepers are forced to use against the parasitic mite Varroa destructor. Here we ha...

Varroa tolerance as a consequence of host immunity may contribute substantially to reduce worldwide colony declines. Therefore, special breeding programs were established and varroa surviving populations investigated to understand mechanisms behind this adaptation. The aim of this study was to investigate the reproductive capacity in the three most...

Mobile phones can be found almost everywhere across the globe, upholding a direct point-to-point connection between the device and the broadcast tower. The emission of radiofrequency electromagnetic fields (RF-EMF) puts the surrounding environment inevitably into contact with this radiation. We have therefore exposed honey bee queen larvae to the r...

With the currently updated risk assessment of three neonicotinoid pesticides, the European Food Safety Authority has confirmed that different applications of these substances represent a risk to wild and managed bees and their use was therefore severely restricted. However, to close further gaps in knowledge, this experiment covers exposure of hone...

Neonicotinoids alone or in combination with pathogens are considered to be involved in the worldwide weakening of honey bees. We here present a new approach for testing sublethal and/or synergistic effects in free flying colonies. In our experiment individually marked honey bees were kept in free flying mini-hives and chronically exposed to subleth...

Thesis
Full-text available
During the last decade the increasing number of honey bee colony losses has become a major concern of beekeepers and scientists world wide. Extensive research and cooperation projects have been established to unravel this phenomenon. Among parasites, pathogens and environmental factors, the use of agrochemicals, most notably the class of neonicotin...

The cuticle is a versatile coat allowing insects to survive in a variety of ecological situations. The polysaccharide chitin is a major cuticle component defining cuticle function. The key players of chitin synthesis and organisation, including chitin synthase-1 (CS-1), the chitin deacetylases vermiform (Verm) and serpentine (Serp), the extracellul...

Back in 1900 already, the Mikrosporidium Nosema apis was described in Apis mellifera. Thereby the Nosemosis remains without symptoms in the beehive to a certain degree. Studies indicate that infected bees have a shortened life span, due to a series of changes in physiological parameters. The consequence of these changes are diarrheal symptoms and t...

Full-text available
The reproductive cycle of the parasitic mite Varroa destructor is closely linked to the development of the honey bee host larvae. Using a within colony approach we introduced phoretic Varroa females into brood cells of different age in order to analyze the capacity of certain stages of the honey bee larva to either activate or interrupt the reprodu...

Horizontal transmission rates of Paenibacillus larvae within and between colonies in relation to spore source or distance to infected colonies were determined. Bacterial spores found on adult bees represent a greater threat to larvae than spores found in honey. Furthermore, different methods for selecting disease tolerant (hygienic) stock were eval...

Die Bienenmilbe Varroa destructor wird weltweit als Hauptursache für periodisch auftretende hohe Völkerverluste angesehen. Dies ist nicht nur ein Problem für die Imkerei, sondern auch eine ökonomische und ökologische Bedrohung für die Kulturlandschaft, da die Bestäubung vieler Wild- und Nutzpflanzen direkt von der Honigbiene abhängt.

Question
I was recently invited to review a paper for a journal (Taylor & Francis, IF 1.6), authored by three scientists from Egypt. As I red through the discussion section of the manuscript, I couldn't believe what I was seeing. Two complete paragraphs from one of my pre-prints published in bioarxiv were 1:1 copy and pasted. I strongly recommended rejecting this paper and any future submissions from the authors.
So far, I did not even get a reply from the handling editor (this was 2 months ago).
Have you made similar experiences and what would you do in my stead with the journal editor? Should I demand a comment on that case? Usually the editor should check a manuscript for plagiarism before sending it out for peer review, shouldn't he/she?
Question
I received an email from Nova press, NY with a request to provide research or review chapter(s) for a book cooperation within the scope of my research interests. I would be interested, if you have i) experience with this kind of publication and ii) where are the benefits in terms of dissemination and/or citations etc.?
As books usually are not made open access, I do only see a benefit for the publisher as they earn money with this. The authors are not paid for their work and have no share on the revenue... so why should I cooperate? Prestige??
Many thanks for your input,
Richard
