Polarization vision and the physiological basis for trichromatic vision in Philaenus spumarius: Understanding host‐seeking behaviour in insect vectors for Xylella fastidiosa control

open access: yesAnnals of Applied Biology, EarlyView.
We investigated the role of vision in host‐seeking behaviour by Philaenus spumarius, the main European vector of Xylella fastidiosa, through an integrated anatomical, optical, physiological, and behavioural study. Our data highlight that the spittlebug uses visual cues, including polarized light, which may aid in detecting the polarized reflections ...
