Abstract Honey bee colonies frequently suffer from high over-winter losses attributed to various factors, including management, poor nutrition, pests, pathogens, and parasites. Most beekeepers have only limited control over these factors. This study looks at the role of the number and timing of hive inspections in relation to over-winter losses, which beekeepers can largely control. The impact of hive inspections on over-winter survival is usually difficult to measure in traditional studies due to confounding factors, including geography, sample size, and variability in practices. This study mines data collected, anonymized and shared from an apiary management software system and includes data from 4,072 hives managed by 717 beekeepers across the continental United States (U.S.) over a five-year period from (2013–2018), consisting of 60,920 inspections to identify the relationship between hive inspections and over-winter survival. Hives are grouped into nine climate zones deemed similar by the National Oceanic and Atmospheric Association (NOAA), and inspections were grouped by season for analysis. Results suggest that more frequent hive inspections are associated with higher over-winter survival rates across most U.S. regions. Unexpectedly, this also includes having relatively more inspections during the winter months in every region. Also, surprisingly only one of the nine climatic regions had significantly different average over-winter survival rates despite the significant geographic and climate difference across the continental U.S. This finding suggests that other factors like management actions may be more important to over-winter survival rates than climate. Finally, this inspection analysis shows that the number of inspections performed by beekeepers is a relevant factor in predicting over-winter hive mortality.

Abstract To enhance the performance of honey bee colonies and to improve the physiological characteristics of honey bee workers in late winter and early spring (dearth period) in Assiut region, Upper Egypt—three pollen substitutes rich in protein and available in the local market were used and compared with bee bread as a control. The pollen substitutes were administrated at 7-day intervals for 15 wk, from December 2018 to March 2019. The rate of food consumption, sealed brood areas, bee population size, and characteristics of hemolymph of honey bee individuals were measured. Stored bee bread was the best protein source for developing honey bee colonies, continued with date syrup, recording the highest sealed brood areas compared with the rest of the diets. All hemolymph parameters under substitute feeding conditions were less than those determined under control conditions (bee bread), and the numbers of spring bees were more than those of winter bees. Total soluble solids (TSS), total hemolymph count (THC), differential hemolymph count (DHC), and hemolymph protein concentration (HPC) differed significantly among the experimental treatments with a significant superiority of date syrup (diet 3) over the others. It can be concluded that the date syrup was more suitable for honey bee colonies which was more favorable than traditional pollen substitute and improved physiological status of honey bee individuals during pollen scarcity periods. So under Upper Egypt conditions, pollen substitute feeding especially date syrup during the winter-early spring period under pollen scarcity helped honey bee colonies to be developed in the early spring seasons.

Abstract Nosemosis is a parasitic disease caused by microsporidian pathogens of the genus Nosema infecting both the Western honey bee, Apis mellifera, and the Asian honey bee Apis cerana. The disease may adversely affect bee colonies and eventually result in high losses in apiculture and agriculture. We determined the Nosema species infecting honey bees and their prevalence in two islands of the Comoros Archipelago (Grande Comore (GCO) and Mohéli (MOH)) in the Southwest Indian Ocean. In Comoros, beekeeping is largely traditional and practiced at subsistence-level, including honey hunting. Five honey bee foragers from 69 colonies in different localities within the two islands were selected and screened for Nosema infection using microscopy and Polymerase Chain Reaction-restriction fragment length polymorphism (PCR-RFLP). Selected positive samples were sequenced to confirm the species identified using PCR-RFLP. We also examined spore loads to determine the intensity of Nosema infections. Nosema ceranae is the only species detected in the two Comoros islands. High prevalence occurred in the large island, GCO (73.9%), while MOH (25.0%) had a low prevalence. Spore counts indicated higher infection intensities in GCO compared to MOH. Generally, PCR-RFLP underestimated the prevalence, although microscopic and molecular diagnostics were well in agreement at the colony level. MOH had lower prevalence and infection intensity compared to GCO, which is the larger island with a higher density of human population. We postulate that the lower levels of pathogen prevalence in MOH in comparison to GCO could arise from minimal human interference.
