Goals / Objectives
Examine importance of Solanum dulcamara and Lycium barbarum as a source of potato psyllid and Liberibacter colonizing potato fields in Washington State.

Project Methods
Caging of infective psyllids on both plant species in autumn to monitor survival of the pathogen and psyllid over winter; examination of newly emerged adult psyllids on both host plants in spring to determine presence of inefective psyllids. -Develop a degree-day model which predicts onset of srping egglaying, development of the spring generation, and first appearance of adults on both weedy host plants. -Develop a molecular approach for detecting the host plant signal (Lycium vs Solanum) within the guts of spring psyllids, for eventual use in assaying psyllids collected from monitoring traps placed near potato fields.
