“…Hygienic behaviour (Rothenbuhler and Thompson, 1956;Spivak and Gilliam, 1998a,b) and undertaking (Visscher, 1983) are the most important behaviours which consist in detecting and removing diseased brood in the larval and pupal stages, and dragging out dead adult bees from the colony. So far, the removal of infected adult individuals has never been observed in honeybees.…”

“…Like all animals, individual honeybees recruit physiological and immunological defence against disease agents (Evans et al, 2006;Schmid et al, 2008;Wilson-Rich et al, 2008). Moreover, as well as individual immunity, honeybees also show several physiological, behavioural and organizational colony-level adaptations such as spatial and behavioural compartmentalization of worker bees on the nest (Naug and Camazine, 2002;Naug, 2008), social fever (Starks et al, 2000), nest construction and enrichment with antimicrobial material (Simone et al, 2009;Baracchi and Turillazzi, 2010;Baracchi et al, 2011), grooming (Kolmes, 1989;Boecking and Spivak, 1999), hygienic behaviour (Rothenbuhler and Thompson, 1956;Spivak and Gilliam, 1998a,b;Richard et al, 2008), undertaking (Visscher, 1983) and self-removing (Kralj and Fuchs, 2006;Naug and Gibbs, 2009;Rueppell et al, 2010). Behaviour, in particular, plays an important role in infection control: removal, quarantine or exile of infected individuals can reduce the exposure of a population once disease takes hold (Clancy, 1996).…”

a b s t r a c tSocial life is generally associated with an increased risk of disease transmission, but at the same time it allows behavioural defence at both the individual and collective level. Bees infected with deformed-wing virus were introduced into observation hives; through behavioural observations and chemical analysis of cuticular hydrocarbons from healthy and infected bees, we offer the first evidence that honeybee colonies can detect and remove infected adult bees, probably by recognising the cuticular hydrocarbon profiles of sick individuals. We also found that health-compromised colonies were less efficient at defending themselves against infected bees, thus facing an ever increasing risk of epidemics. This work reveals a new antiseptic behaviour that can only be interpreted as an adaptation at colony level and one which should be considered an element of the social immunity system of the beehive, re-enforcing the view of a colony as an integrated organism.

“…This disease resistance resulting from social behaviour has been known since the ground-breaking work of Walter Rothenbuhler on hygienic behaviour (Rothenbuhler 1964;Rothenbuhler and Thompson 1956). Workers uncap cells with larvae infected with Paenibacillus larvae and remove the infected individuals from the colony.…”

“…Hygienic behaviour has therefore successfully been used in selective breeding in the control of various brood diseases (e.g. American foulbrood, chalk brood and Varroa mites) (Harbo and Harris 1999;Palacio et al 2010; Rothenbuhler and Thompson 1956;Spivak and Gilliam 1998). As there are several recent reviews available on hygienic behaviour and the importance of grooming for social insect colony defence, we will not address this issue in any deeper detail and would like to direct the reader to the excellent reviews of Evans and Spivak (2010) and Wilson-Rich et al (2009) and references therein.…”

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

A substance in honey bee larvae inhibits the growth of Paenibacillus larvae larvae

-Paenibacillus larvae larvae, a Gram-positive and spore-forming bacterium, is the cause of American foulbrood. We investigated the resistance of larvae of different ages from different colonies against P. larvae larvae. We prepared ethanol-water-extracts from two, three, four and five day old larvae and also larvae in two capped stages to test the ability of the homogenates to inhibit the growth of P. larvae larvae in vitro. There were age and colony dependent differences in the inhibiting potentials of larvae. The results suggest that the concentration of the inhibiting substance(s) in the extract might be responsible for the known different degree of resistance against P. larvae larvae in vivo. Our results further show that the extracts of the two-, three-and four-day-old larvae have the ability to inhibit the growth of P. larvae larvae very well, while starting around day five the inhibiting effect is gradually reduced.Apis mellifera carnica / Paenibacillus larvae larvae / honeybee larvae / age-related resistance /
