Infection avoidance behaviour: female fruit flies adjust foraging effort in response to internal and external cues of viral infection. Vale, P. F. & Jardine, M.

Paper doi abstract bibtex Infection avoidance behaviours are the first line of defence against pathogenic encounters. Behavioural plasticity in response to internal or external cues can therefore generate potentially significant heterogeneity in infection. We tested whether Drosophila melanogaster exhibits infection avoidance behaviour during foraging, and whether this behaviour is modified by prior exposure to Drosophila C Virus (DCV) and by the risk of DCV encounter. We examined two measures of infection avoidance: (1) the motivation to feed in the presence of an infection risk and (2) the preference to feed on a clean food source over a potentially infectious source. While we found no clear evidence for preference of clean food sources over potentially infectious ones, female flies were less motivated to feed when presented with a risk of encountering DCV, but only if they had been previously exposed to the virus. We discuss the relevance of behavioural plasticity during foraging for host fitness and pathogen spread.
