Resumen
La vida social es asociada generalmente a un aumento del
riesgo de trasmisión de enfermedades, pero al mismo tiempo habilita un comportamiento de defensa tanto del
individuo como en el nivel colectivo. Se introdujo abejas infectadas con el
virus de la deformación de las alas en colmenas de observación. A traves de
observaciones del comportamiento y de aálisis químicos de sustancias
hidrocarbonadas de las cuticulas de abejas enfermas y sanas, se encontró la
primera evidencia que las colonias de abejas melíferas pueden detectar y
remover abejas adultas infectadas, probablemente por el reconocimiento de los perfiles
de hidrocarburos cuticulares de los individuos enfermos. También encontramos
que las colonias con la salud comprometida fueron menos enficientes en
defenderse de las abejas infectadas, aún enfrentando un riesgo de aumento epidémico.
Este trabajo revela un nuevo comportamiento antiséptico que sólo puede ser
interpretado como una adaptación a nivel de colonia, y que debería ser
considerado un elemento del sistema de inmunidad social de la colonia,
reforzando la visión de la colonia como un organismo integrado

Abstract
Social 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.
