Take flight: predation risk induces wing polyphenism and dispersal in the aphid Myzus persicae
Pest Management Science, EarlyView.Predator risk above a critical density induces winged morphs in Myzus persicae, promoting dispersal and reducing predation compared with wingless aphids. This density‐dependent phenotypic plasticity enhances survival but may compromise biological control by facilitating aphid dispersal.
