“…The colony's nutritional status affected not only the transcriptomic changes but also behavioural adaptations in individual bees. For example, Varroa jacobsoni -infested colonies increased the removal of infested brood when they had higher pollen stores (Janmaat and Winston 2000).…”

Pharmacophagy and pharmacophory: mechanisms of self-medication and disease prevention in the honeybee colony (Apis mellifera)

-Apitherapy promises cures for diseases in human folk medicine, but the effects of honeybee produced and foraged compounds on bee health are less known. Yet, hive products should chiefly facilitate medication and sanitation of the honeybees themselves rather than other organisms. We here review the impact of both self-produced gland secretions and foraged hive products (pharmacognosy) on colony health. Although foraged plant-derived compounds vary highly in antibiotic activity depending on the floral and regional origins, secondary plant metabolites in honey, pollen and propolis are important for the antibiotic activity against pathogens and parasites. However, specific bee health-enhancing activities of bee products should clearly be distinguished from the effects of an intact nutrition ensuring the basic immune competence of bees. Further unravelling the interactions among groups of active substances or individual compounds used in concert with specific behavioural adaptations will deepen our understanding of the natural potential of honeybees to maintain colony health.honey / propolis / pollen / bee bread / royal jelly / antimicrobial activity / self-medication / host-parasite interaction

“…All the parasites die if they have not attained the adult stage when the bees emerge, or when they are removed from the cells. Although the brood removal rate infested with V. destructor is greatly influenced by climate conditions, such as pollen flow (Janmaat & Winston 2000), the real effect of hygienic behavior on varroa infestation in A. mellifera colonies is unknown. However, a higher rate of brood uncapping in infested combs should affect the population dynamics of the mite due to the deleterious effects on the varroa progeny.…”

PALAVRAS-CHAVE: Comportamento higiênico, varroosis, infestação natural, abelha africanizadaABSTRACT -Varroosis, a disease caused by the mite Varroa destructor Anderson and Treuman has killed hundreds of thousands of Apis mellifera L. colonies in various parts of the world. Nevertheless, the damage caused by this mite varies with the type of bee and climate conditions. Varroa causes little damage to Africanized bee colonies in Brazil, as the infestation rates are relatively stable and low. We evaluated the hygienic behavior (uncapping and removal of brood) of highly hygienic Africanized bees using combs with worker brood cells infested (naturally) and no infested with V. destructor. The daily uncapping rate, measured in eight colonies during six days, was 3.5 fold higher in the combs infested with varroa compared to no infested combs. The results show that the Africanized bees are able to recognise and remove brood cells naturally infested with V. destructor what is an important mechanism for tolerance against varroa.

“…For example, when there is abundant nectar and pollen in the field, the expression of HB also increases, because the need for space to store these products is created in the colony and that also stimulates the queen to lay more eggs in cells that should be clean (8,9,11,24) . This agrees with the results of this study, since during the autumn (season with more intense nectar flow than spring) 16.4 % more honey was produced than during the spring, but no differences were found between the two groups of colonies for this variable.…”

“…La expresión del CH en una colonia de abejas depende de factores como la proporción y edad de las abejas que realizan tareas higiénicas (5)(6)(7) , la entrada de néctar y polen colectados por las obreras (8)(9)(10)(11) y la fortaleza de la colonia (5) . Pero el factor más importante en la expresión de este comportamiento, es su componente genético.…”

RESUMENEl objetivo del estudio fue comparar la producción de miel y los niveles de Varroa destructor entre colonias de abejas africanizadas (AA) (Apis mellifera) con alto y bajo comportamiento higiénico (CH) en el altiplano semiárido de México. Se midió el nivel de CH a 57 colonias por congelamiento de la cría con nitrógeno líquido (N 2 ). Las colonias se clasificaron en dos grupos: alto CH (> 95 %) y bajo CH (< 50 % de remoción de la cría muerta por congelamiento en 48 h). La producción de miel se evaluó durante el otoño y la primavera y el nivel de infestación por Varroa en abejas adultas se determinó antes y durante las cosechas de miel. En primavera, las colonias con CH alto produjeron significativamente más miel que las de CH bajo (21.4 ± 4.7 vs 13.4 ± 5.0 kg; P<0.01). No hubo diferencias entre los dos grupos de colonias para los niveles de Varroa (P>0.05). Estos resultados sugieren que aparentemente el comportamiento higiénico no tiene un efecto mayor en la resistencia de las AA al crecimiento poblacional del ácaro. También sugieren que el comportamiento higiénico alto podría contribuir a incrementar la producción de miel en épocas del año con flujo reducido de néctar.PALABRAS CLAVE: Abejas melíferas, Comportamiento higiénico, Varroosis, Tolerancia, Cosecha de miel. ABSTRACTThe aim of this study was to compare the honey yields and levels of Varroa destructor between colonies of Africanized honey bees (AHB) (Apis mellifera) showing high and low hygienic behavior (HB) in Mexico's semi-arid high plateau. The degree of HB of 57 colonies was measured using the liquid nitrogen (N 2 ) brood-freezing technique. The colonies were categorized into two groups: high HB (> 95 %) and low HB (< 50 % removal of freeze-killed brood at 48 h). Honey production was evaluated in fall and spring and the level of Varroa on adult bees was determined before and during the honey harvests. The colonies with high HB produced significantly more honey than the colonies with low HB only during the spring crop (21.4 ± 4.7 vs 13.4 ± 5.0 kg; P<0.01). There were no significant differences between the two groups of colonies for levels of infestation by V. destructor (P>0.05). These results suggest that apparently HB does not have a major role in restraining the growth of Varroa populations in AHB. They also suggest that high levels of HB could contribute to increase honey production in AHB colonies during times of the year with limited nectar flow.
