First evidence of large hive beetle (Oplostomus fuligineus) invasion in the Arabian region: a survey‑based study of spread and future management

Articles

Large hive beetles (Oplostomus fuligineus, LHB) have long been recognized as significant pests of honey bee colonies, particularly across the African continent. Although LHBS are native to Sub-Saharan Africa, they have recently been recorded in North Africa, feeding primarily on young bee larvae within colonies, which leads to severe damage, especially in weaker colonies. In…

The Latitudinal Biotic Interaction Hypothesis revisited: contrasting latitudinal richness gradients in actively vs. passively accumulated interaction partners of honey bees

Articles

Contrasting hypotheses suggest that the number of biotic interactions per species could either increase towards the equator due to the increasing richness of potential interaction partners (Neutral theory), or decrease in the tropics due to increased biotic competition (Latitudinal Biotic Interaction Hypothesis). Empirical testing of these hypotheses remains limited due to practical limitations, differences in…

A systematic meta-analysis of the efficacy of treatments for a global honey bee pathogen – the Varroa mite

Articles

Highlights This study presents a meta-analysis of treatments for the pathogen Varroa destructor. Data was drawn from 138 studies, carried out in 30 countries on 5 continents. Synthetic chemical treatments were effective against the pathogen, but harmed bees. Biological treatments showed promise in improving bee health, but with a small sample. Organic chemical treatments currently…

Spatio-temporal variation in pollen collected by honey bees (Apis mellifera) in rural-urban mosaic landscapes in Northern Europe

Articles

Pollen is a source of protein, lipids, vitamins and minerals for bees and other flower-visiting insects. The composition of macro- and micronutrients of pollen vary among different plant species. Honey bees are long-distance foragers, collecting nectar and pollen from plants within several kilometers of their hive. Availability of pollen within the foraging range of honey…

Influence of Hyperthermia Treatment on Varroa Infestation, Viral Infections, and Honey Bee Health in Beehives

Articles

The mite Varroa destructor is widely acknowledged as the most destructive threat to honey bee (Apis mellifera) colonies on a global scale. Varroa mite infestations in bee colonies are intricately linked with viral infections, collaboratively leading to diminished bee populations and accelerated colony losses. Extensive research has firmly established the correlation between varroa mites and…
