چکیده : 

Interactions between individuals in a society are the basis of effective task allocation. Division of labour

plays a critical role in the ecological efficiency of social insect societies. In this study we tested whether

social context, specifically the number of workers present, affects thermoregulatory task performance in

honeybees, Apis mellifera.We report here that worker bees assayed singly were significantly less likely to

initiate fanning behaviour in response to elevated temperature than bees assayed in small groups of

three or 10 workers. Bees assayed in groups also showed lower response thresholds than those assayed

alone. The likelihood for fanning behaviour varied significantly among behavioural castes, while thermal

response thresholds did not. These results suggest that worker task performance depends on the

presence of other workers and offer another method by which division of labour in societies is organized
