Genetic variation in trophic avoidance shows fruit flies are generally attracted to bacterial pathogens

Katy M. Monteith,

Abstract: Pathogen avoidance behaviours are often assumed to be an adaptive host defence from infection. However, there is limited experimental data on the prerequisite for this assumption: heritable, intra-population phenotypic variation for avoidance. We investigated trophic pathogen avoidance in 122 inbred Drosophila melanogaster lines, and in a derived outbred population. Using the FlyPAD system, we tracked the feeding choice that flies made between substrates that were either clean or contained a bacterial pathogen… Show more
