Several natural or semi-natural areas near Twin Falls are being monitored during the winter for potato psyllids. Sites were selected near watercourses where the alternative host plant bitter nightshade is found. Thus far, no psyllids have been found in direct inspection of plants; however, two adult potato psyllids were found on a yellow sticky trap near Shoshone Falls in late March. Whether these psyllids overwintered or have migrated to our area is unknown. They will be tested for liberibacter, the bacterium that causes ZC, and monitoring efforts will continue through the season. More information on potato psyllids and ZC can be found below.
