Abstract
Pathogens may change host behaviour for its own benefit to spread or elicit host behavioural defence. Recent investigations show that the parasitic mite Varroa destructor which causes high losses of bee colonies, induces changed flight behaviour of infested workers. Infested bees do not return as frequently as non-infested workers. Flight of infested bees is prolonged and orientation impaired. The aim of the project is to investigate the influence of other diseases, in particular the impact of microsporidian Nosema apis on flight behaviour of foragers to confirm whether changed behaviour is a general response mechanism of bees to diseases. For this purpose we will test the orientation ability of infested bees and returning time after release. Further, we will explore learning of infested bees which might underlay changes in behaviour. We plan to test the immune response of diseased foragers because the activation of the immune system could cause lower learning ability and subsequently impaired orientation. The project will give an new information whether altered flight is a general response of bees to diseases and will elucidate possible physiological mechanisms underlying these changes.
