Management of Potato Psyllids
Adult potato psyllids have been detected in some fields in western and south central North Dakota potatoes. This insect is mainly found in the Rocky Mountain states. Potato psyllids are believed to overwinter in the southern most U.S. states and Mexico and re-establish to northern locations in the summer via wind dispersal. They are not known to overwinter in North Dakota. Potato psyllids are of principal concern because they can transmit the Liberibacter bacterium which causes Zebra chip.
