“…Complementing capped brood data, colony size (approximate number of adult bees per hive) also showed temporal fluctuations (Fig. 1D ), which is consistent with expected seasonal variation [ 40 ]. Baseline colony sizes for the NTC group were smallest at W0 (~15,000 adults/hive) and largest at W20 (~38,000 adults/hive), with the P and S vehicle controls showing similar temporal dynamics.…”

Managed honey bee (Apis mellifera) populations play a crucial role in supporting pollination of food crops but are facing unsustainable colony losses, largely due to rampant disease spread within agricultural environments. While mounting evidence suggests that select lactobacilli strains (some being natural symbionts of honey bees) can protect against multiple infections, there has been limited validation at the field-level and few methods exist for applying viable microorganisms to the hive. Here, we compare how two different delivery systems—standard pollen patty infusion and a novel spray-based formulation—affect supplementation of a three-strain lactobacilli consortium (LX3). Hives in a pathogen-dense region of California are supplemented for 4 weeks and then monitored over a 20-week period for health outcomes. Results show both delivery methods facilitate viable uptake of LX3 in adult bees, although the strains do not colonize long-term. Despite this, LX3 treatments induce transcriptional immune responses leading to sustained decreases in many opportunistic bacterial and fungal pathogens, as well as selective enrichment of core symbionts including Bombilactobacillus, Bifidobacterium, Lactobacillus, and Bartonella spp. These changes are ultimately associated with greater brood production and colony growth relative to vehicle controls, and with no apparent trade-offs in ectoparasitic Varroa mite burdens. Furthermore, spray-LX3 exerts potent activities against Ascosphaera apis (a deadly brood pathogen) likely stemming from in-hive dispersal differences, whereas patty-LX3 promotes synergistic brood development via unique nutritional benefits. These findings provide a foundational basis for spray-based probiotic application in apiculture and collectively highlight the importance of considering delivery method in disease management strategies.

“…The brood area rapidly increases following food availability. After reaching a peak during the late spring or early summer, it slowly decreases, or can have another smaller peak before finally stopping in the autumn (Harris, 2008;Mattila et al, 2001). According to Woyke (1984), colonies with the largest amount of brood do not always become the most populous, nor do the most populous colonies always produce the most honey.…”

SummaryThe objective of this study was to compare the colony development cycle (unsealed and sealed worker brood, drone brood, pollen and colony strength) of two Apis mellifera carnica subpopulations in two distinct environments (alpine and continental). At each test location were two sub groups of 12 colonies headed by naturally mated sister queens from either the Institute of Apiculture Lunz am See, Austria (AT) or from the Faculty of Agriculture University of Zagreb, Croatia (HR). Colony development was monitored every 14 days. The HR genotype, adapted to a continental climate, had faster spring brood development in both environments. During spring and early summer the AT genotype maintained the number of sealed brood cells at a constant level in the more favourable conditions, although the amount of unsealed brood reached its maximum in early June. The environment influenced colony development, food stores and colony strength. Interaction between genotype and environment did not affect the number of unsealed brood cells, but the difference was statistically significant for the number of sealed brood cells. The study indicated the presence of a number of genotype and environment interactions between the two honey bee genotypes and their colony traits. Desarrollo de colonias de dos genotipos Carniola (Apis mellifera carnica) en relación con el medio ambiente ResumenEl objetivo de este estudio fue comparar el ciclo de desarrollo de la colonia (cría de obreras operculada y no operculada, cría de zánganos, el polen y la fuerza de colonias) de dos subpoblaciones de Apis mellifera carnica en dos ambientes distintos (alpino y continental). En cada lugar de prueba se pusieron dos subgrupos de 12 colonias encabezadas por reinas hermanas fecundadas naturalmente, ya sea del Instituto de Apicultura Lunz am See, Austria (AT) o de la Facultad de Agricultura de la Universidad de Zagreb, Croacia (HR). El desarrollo de las colonias se controló cada 14 días. El genotipo HR, adaptado a un clima continental, tuvo un desarrollo más rápido de la cría en primavera en ambos ambientes. Durante la primavera y principios del verano el genotipo AT mantuvo el número de celdas de cría operculadas a un nivel constante en las condiciones más favorables, aunque la cantidad de cría abierta alcanzó su máximo a principios de junio. El ambiente influyó en el desarrollo de las colonias, la reserva de alimentos y la fuerza de la colonia. La interacción entre el genotipo y el medio ambiente no afectó el número de celdas de cría sin opercular, pero la diferencia fue estadísticamente significativa para el número de celdas de cría operculada. El estudio indicó la presencia de una serie de interacciones del genotipo con el medio ambiente entre los dos genotipos de abejas y los caracteres de sus colonias.Keywords: Apis mellifera carnica, genotype x environment interactions, colony development, local adaptation 262 Drazic et al.
