Special Issue Information

Dear Colleagues,

Honeybees' growing challenges have garnered significant attention due to various emerging biological and environmental threats. These challenges include losses driven by pathogens, the spread of invasive alien species, the rise of resistance phenomena, exposure to environmental contaminants, i.e., pesticides and pollutants, and climate change.

This Special Issue, titled "Advances in Honeybee and Their Biological and Environmental Threats", explores the multifaceted nature of apiculture and the complex interactions between managed honeybees, their biological threats, and their environment.

Furthermore, this Special Issue wants to collect data on honey bees as crucial agricultural and environmental health bioindicators, offering valuable insights into ecosystem status through their biological responses and behavior.

This Special Issue invites original research papers and comprehensive reviews that address the diverse aspects of biological and environmental threats emerging in apiculture, non-managed bee colonies, and wild bees. Contributions that enhance our understanding and propose innovative solutions to the current challenges in this essential sector are highly encouraged.

The Effect of Land Cover on the Nectar Collection by Honeybee Colonies in Urban and Rural Areas

In the context of increasing urbanisation, the question arises as to whether urban environments can provide honeybee colonies with floral resources comparable to those available in rural areas. The present study sought to evaluate the impact of land cover on nectar collection by bees in urban and rural apiaries. To this end, changes in the mass of 10 hives located in five urban–rural site pairs were monitored over two years (2021–2022) to assess nectar yield, weight loss, and the number of foraging days. The 3 km surroundings of each apiary were analysed using Sentinel-2 satellite imagery from the S2GLC-PL (National Satellite Information System 2025). The analysis identified eight distinct land cover classes: anthropogenic, agricultural, broad-leaved forest, coniferous forest, grassland, shrubs, wetlands, and water bodies. The findings revealed no statistically significant variation in the total nectar collected between urban and rural colonies (72.9 kg vs. 64.5 kg; p > 0.6). However, urban colonies exhibited a significantly higher number of foraging days (67 vs. 56). No significant correlations were identified between specific land cover types and nectar yield. Principal component analysis (PCA) and clustering revealed distinct landscape gradients, yet these did not influence nectar collection. The findings of this study indicate that diverse urban environments have the capacity to support beekeeping to a similar extent as rural areas and may even have superior conditions, provided that the continuity and diversity of nectar plants are maintained.

In urbanized environments, the expansion of urban areas has led to the creation of fragmented green spaces such as gardens and parks. While these areas provide essential habitats for pollinators, they may also inadvertently concentrate specimens of different species, increasing opportunities for pathogen transmission. This study highlights the importance of investigating pathogen dynamics in urban ecosystems, focusing on managed pollinators, such as Apis mellifera Linnaeus, 1758, and their wild counterparts. Over a two-year monitoring period in Milan, Italy, we examined the interactions between pollinator populations in urban green spaces and the spillover of honeybee pathogens. Our findings confirm widespread RNA virus transmission between honeybees and wild pollinators, supporting the previous studies. Notably, the Acute Bee Paralysis Virus (ABPV) exhibited the highest prevalence across both sampling years, underscoring its significant role in pathogen dynamics. These results emphasize the need for regular research to mitigate pathogen spillover risks in urban pollinator communities and inform conservation strategies. Full article

The present study set out to compare the performance of honeybees maintained in urban and agricultural environments across various regions in Poland. A range of measurements and observations were used to assess overwintering, development, strength, swarming behaviour, honey yield, and Varroa destructor infestation in bee colonies in five towns and five surrounding villages. The rural apiaries were located 4.5–39.5 km away from the urban apiaries. The colonies were kept in wooden Dadant hives and were led by Apis mellifera carnica queens. The brood count and colony strength were assessed based on the Liebefeld method, while Varroa destructor infestation levels in the colonies were determined using icing sugar at the end of July. The urban apiaries exhibited significantly higher brood-rearing dynamics. Consequently, an increase in brood count in spring resulted in a significant increase in Varroa infestation levels in summer. In certain regions, urban apiaries exhibited higher honey production, though this was influenced by geographic location and the availability of bee forage. The significant variation in most traits, including honey production, was observed depending on the region. Variations between years in the study were observed in bee colonies overwintering, brood numbers in the pre-spring period, and bee population in summer. This may suggest the presence of differing weather conditions. Full article
