potato psyllid - Bactericera cockerelli

The potato psyllid (Bactericera cockerelli), also known as the tomato psyllid, is a pest that can spread plant diseases to various crops. Potato psyllids and other psyllid species are difficult to track, and thus their non-crop whereabouts have been poorly understood. A new study, however, shows that DNA analysis of psyllids’ gut content can identify plants they previously fed on, providing clues about the stops they make before infesting crop fields.
