Weedy sanctuaries and non-host whistle stops for potato psyllid. Potato Country USA. 35(1):36-38. Interpretive Summary: Studying the landscape-level movements of psyllids between weeds and crops has proven challenging largely because of limitations in the use of existing methods on a small yet highly mobile insect that occurs on a large diversity of plant species. New methods are therefore needed to study the landscape ecology of potato psyllid. Researchers at the USDA Agricultural Research Service laboratory in Wapato, WA have recently demonstrated that prior landscape-level movements of potato psyllid can be tracked by identifying what plants the psyllids previously fed upon. This method is now being used to identify the weed sources of Liberibacter-infected potato psyllid colonizing fields of potato.
