Potato/tomato psyllid (Bactericera cockerelli)
Pest description and crop damage Adult psyllids resemble miniature cicadas, while the immature stages are scale-like and mostly sedentary, much more so than aphids, and look like white fly nymphs. Feeding by immature stages sometimes causes a physiological foliage disorder known as "psyllid yellows" in potatoes. Symptoms of psyllid yellows are very similar to those caused by phytoplasmas transmitted by leafhoppers.
