Potato Psyllid Detected in North Dakota

Potato psyllid, Bactericera cockerelli, was detected last week in a commercial potato field near Tappen in central North Dakota. Several yellow sticky cards were submitted to the NDSU Plant Diagnostic Lab and Extension Entomology by a crop consultant. One of the cards contained three potato psyllids. Species identification was confirmed using DNA analysis. The potato psyllids also were tested for Liberibacter, the causal agent of zebra chip disease in potatoes. All three potato psyllids tested negative for Liberibacter.

Potato growers should be monitoring their fields for potato psyllids. For more information on potato psyllids, including biology and control information, please consult Management of Potato Psyllids – 2016.
