“…a decrease in energetic costs associated with the maintenance of an up-regulated immune system will help bees to allocate their energy to perform vital tasks (e.g. foraging, raring brood) and to maintain higher storage protein levels required for overwintering success.”
Propolis envelope in Apis mellifera colonies supports honey bees against the pathogen, Paenibacillus larvae

“Managing honey bees in man-made hives with smooth interior walls has interfered with a critical, natural defense mechanisms of the honey bee colony: the bees do not construct a natural propolis envelope inside the hive as they do in natural tree cavities. Our results provide additional evidence for the importance of the propolis envelope within the nest, in this case protecting the brood from P. larvae infection, resulting in a lower infection load two months following the challenge.”

“Because honey bee mouthparts are used for collecting and storing nectar and pollen, grooming and trophallaxis between adults, feeding larvae, and cleaning the colony, they are an important interface between the bees’ external and internal environments and serve as a transmission route for core gut bacteria and pathogens alike…Based on the taxonomic results, the propolis envelope appeared to reduce pathogenic or opportunistic microbes and promote the proliferation of putatively beneficial microbes on the honey bee mouthparts, thus reinforcing the core microbiome of the mouthpart niche.”

“…in relation to V. destructor, [Deformed Wing Virus] titers increased significantly less in colonies with added propolis than in propolis-removed colonies, whereas [Sacbrood Virus] titers were similar. Colonies with added propolis were also significantly stronger than propolis-removed colonies.”

Measuring Beekeepers’ Economic Value Of Contract Enhancements in Almond Pollination

Fenton, M., Goodrich, B., & Penn, J. (2023). Measuring beekeepers’ economic value of contract enhancements in almond pollination [SSRN Scholarly Paper]. https://doi.org/10.2139/ssrn.4580491
“In 2022, California’s 1.3 million almond acres required roughly 2.6 million honey bee colonies, an estimated 89% of all honey bee colonies in the US as of January 2022 (Land IQ, 2022; US Department of Agriculture (USDA) National Agricultural Statistics Service (NASS), 2022a, 2022b). While the demand for almond pollination is currently being met by the US beekeeping industry, Durant and Ponisio (2021) found that over half of surveyed almond growers showed a strong concern about declining bee health and the lack of available honey bee colonies in the future, and 47% showed strong concern about the lack of skilled commercial beekeepers able to provide pollination services in the future.”

“Honey bee colonies, especially those used for crop pollination, are without question being exposed to a diverse array of agrochemicals, especially fungicides and some bee-toxic pesticides as seen here and in other published studies… Brood is particularly vulnerable to impacts from pesticide toxicity…The impacts of in-hive chemicals continue to be a concern given that the amitraz metabolite, DMPF, was found at 5,160 ppb in dead and dying bees near corn.”

“This study showed that resistance to varroa mites is present in the honey bee population in the United States, nonreproduction of mites was highly correlated with the growth of a mite population, and nonreproduction of mites may be a valuable characteristic for selecting bees for resistance to varroa mites.”
Textured hive interiors increase honey bee (Hymenoptera: Apidae) propolis–hoarding behavior

“Pairwise comparisons showed that propolis deposition was not significantly different among the three textural treatments; however, textural treatments interacted with time to show a more consistent benefit from plastic propolis trap material or roughened interior surface over saw kerfs. Although direct health benefits were not measured, this work shows that it is comparatively simple to increase propolis deposition above background levels by increasing textural stimuli in hive interiors.”

“Across 41 networks in which A. Mellifera was present… Apis mellifera was the only documented visitor to 4.48% of plant taxa (median = 0%, range = 0%–66.67%) and contributed the majority (≥50%) of visits to 17.28% of plant taxa (median = 0%, range = 0%–100%).”

“The fact that rearing temperature has a considerable

with a reward, but no effect on [Fluctuating Asymmetry], strongly implies that the most important consequence of abnormal rearing temperatures are neural deficiencies rather than physical abnormalities.”

“By the end of the second summer of the study, the colonies living in small hives had a mean Varroa infestation rate of adult bees that was only about one third of that found in the colonies living in large hives. Moreover, while none of the small-hive colonies showed signs of disease, seven of the 12 large-hive colonies showed symptoms of high infection with the deformed wing virus (DWV), which is closely associated with a high infestation of Varroa.”

“The observations show unequivocably that the bees preferred small-hole boxes and indicate that the threshold of their ability to discriminate between hole sizes lies somewhere between 7.9 and 31 cm2. This marked responsiveness to entrance area is an indication that a small entrance may be significant in the survival of the colony.”

“A scout bee’s inspection of a nest site spans approximately 40 min.
During this time a scout spends most of her time at the nest site, engaged in numerous brief inspections inside and outside the nest cavity. When inside a cavity, a scout’s principal behavior is rapid walking about the cavity’s inner surfaces.”

“…it is now clear that a feral population of these bees, infested with V. destructor, persists in the Arnot Forest in New York State. Indeed, there is many, if not more, feral colonies living in this forest now as when they were censused 24 years earlier in 1978, hence long before the arrival of V. destructor.
