Special Issue Information

Dear Colleagues,

Honeybees are one of the most ancient living organisms on our planet, on which the sustainability of all ecosystems depends. Despite historical advances, modern beekeeping faces numerous challenges. Factors such as habitat loss, pesticide exposure, climate change, and the proliferation of pests and diseases (notably Varroa mites) have contributed to a decline in bee populations. While modern challenges pose significant threats to bee populations, recent advances offer promising solutions. Through genetic research, innovative smart technologies, sustainable pest management, improved nutrition, conservation efforts, and community involvement, the future of beekeeping looks hopeful.

This Special Issue focuses on the current and emerging trends in the development of apiculture. By covering a broad spectrum of topics, it aims to provide valuable insights and practical solutions that can be applied to improve bee health, productivity, and sustainability. This Special Issue will include a broad range of interdisciplinary studies embracing agriculture, biology, genetics, numerical methods, chemistry, and engineering. All types of articles, such as original research, opinions, and reviews, are welcome.

Infestation by Varroa destructor is responsible for high mortality rates in Apis mellifera colonies worldwide. This study was designed to develop and test under field conditions a new free software (VarroDetector) based on a deep learning approach for the automated detection and counting of Varroa mites using smartphone images of sticky boards collected in honeybee colonies. A total of 204 sheets were collected, divided into four frames using green strings, and photographed under controlled lighting conditions with different smartphone models at a minimum resolution of 48 megapixels. The Varroa detection algorithm comprises two main steps: First, the region of interest where Varroa mites must be counted is established. From there, a one-stage detector is used, namely YOLO v11 Nano. A final verification was conducted counting the number of Varroa mites present on new sticky sheets both manually through visual inspection and using the VarroDetector software and comparing these measurements with the actual number of mites present on the sheet (control). The results obtained with the VarroDetector software were highly correlated with the control (R2 = 0.98 to 0.99, depending on the smartphone camera used), even when using a smartphone for which the software was not previously trained. When Varroa mite numbers were higher than 50 per sheet, the results of VarroDetector were more reliable than those obtained with visual inspection performed by trained operators, while the processing time was significantly reduced. It is concluded that the VarroDetector software Version 1.0 (v. 1.0) is a reliable and efficient tool for the automated detection and counting of Varroa mites present on sticky boards collected in honeybee colonies.

While marking queens is an optional rather than mandatory technique, it is increasingly becoming a standard practice in modern beekeeping. Finding queens in strong colonies and large apiaries is a time-consuming process. The visible and durable marking of the queen enables it to be seen more quickly, directly improving productivity in apiary management. This study examined a new technique for marking queens using an oil-based marker, which involved marking not only the thorax (as a standard technique) but also the wings and abdomen. The durability of the marking was assessed by measuring color retention at the start of the experiment and after five months. Two groups of queens were formed: an experimental group, marked with the new technique on three body parts—Group O (n = 12) and a control group of unmarked queens—Group N (n = 12). The most durable color retention was observed on the thorax (54.4%) and abdomen (14.4%), while retention on the wings was weaker (2.4%), necessitating reapplication during the season. Considering the proportion of the total marked area, abdomen marking gave better results (9.5%) compared to the thorax (5.4%) and wings (0.6%) marking. The application of this marking technique showed no negative effects on queen acceptance, survival, or supersedure. Marking three body parts can increase the queen’s visibility in a non-invasive way, improving work efficiency. Full article

The division of labor among honeybee workers contributes to efficient pollination activities. Lipids play a crucial role in behavioral regulation, with pollen serving as a primary source of these lipids. However, the regulatory effect of pollen lipids on the division of labor of honeybee workers remains to be studied. In this study, an in-depth lipidomic analysis based on HPLC-QTOF-MS and UPLC-IM-QTOF-MS was applied. We conducted the first comprehensive lipidomic profiling of the abdomen, brain, and intestine of emerging, nursing, and foraging bees, as well as pollen, thereby establishing a lipid library comprising 646 lipid species. The lipid composition of pollen was found to exhibit characteristics similar to those of honeybee workers, with alpha linolenic acid (ALA) validated as a key labor characteristic lipid. Moderate dietary ALA supplementation reshaped lipid levels and facilitated metabolism related to the labor of division. These findings advance the field of lipidomic analysis in honeybee workers, revealing a novel behavioral regulator and extending the understanding of the nutritional regulation of ALA in the division of labor among honeybee workers.

Global climate change, intensive agriculture, and anthropogenic pollution adversely affect flowering plants and the vitality of bee colonies. In nutritional stress conditions, bees deplete the food reserves of their fat body to sustain colony life. Beekeepers play a critical role by providing supplemental nutrient solutions. This study examines the effects of various sugar syrups on the fat body development of worker bees (Apis mellifera macedonica). The colonies were divided into one control group and five experimental groups: one fed with 1:1 sugar/water syrup, one with 2:1 sugar/water syrup, one with inverted syrup (Apiinvert), one with HFCS (high-fructose corn syrup) (Isosweet), and one with 1:1 honey/water syrup. Fat body development was assessed through meticulous dissection, and the degrees of development were documented using a USB digital microscope (Bresser). The results indicate significant seasonal variations in fat body development, with winter depletion and recovery influenced by supplemental feeding. Apiinvert and honey/water syrup promoted higher fat body stages, while Isosweet led to elevated fifth degrees of development but raised concerns about potential toxicity due to the hydroxymethylfurfural (HMF) formation of improperly stored syrups. This study concludes that adequate supplemental feeding with easily digestible sugars is critical for promoting fat body development, enhancing winter survival, and ensuring overall colony health. These findings provide practical guidance for beekeepers to optimize feeding strategies and support resilient bee colonies. Full article
