Technical Abstract: The potato psyllid, Bactericera cockerelli (Sulc) (Hemiptera: Triozidae), is a major pest of potatoes that can cause yield loss by direct feeding on crop plants and by vectoring a bacterial pathogen, Candidatus Liberibacter psyllaurous (a.k.a. Candidatus Liberibacter solanacearum). In recent years, there have been no studies regarding resistance of potato to the potato psyllid or the bacterial pathogen that the psyllid vectors. Thus, the objectives of this study were to determine the effects of potato germplasm on adult potato psyllid behavior and transmission of Ca. L. psyllaurous. Potato varieties and breeding clones tested included 'Atlantic', 'GemStar Russet', '463-4', 'P2-3', 'P2-4', 'Etb 5-31-3', 'Etb 6-21-3', 'Etb 6-21-5', 'A00ETB12-2', 'A00ETB12-3', 'A05379-69', 'A05379-211', 'Russet Norkotah', 'King Harry', 'NY138', 'BTX1749-1W/Y', 'NDTX731-1R', 'TX05249-10W', 'ATX85404-8W', 'ATTX98500-3PW/Y', 'BTX1544-2W/Y', and 'AOTX95295-1W'. Plant genotype significantly impacted the occurrence and duration of psyllid probing, the duration of psyllid cleaning, resting, and the amount of time psyllids spent off the potato leaflet as well as transmission of Ca. L. psyllaurous. For the potato genotypes in which there were significant decreases in transmission compared to controls, there was often an unclear relationship between the occurrences and duration of behaviors and subsequent bacterial transmission. The results are useful for development of an integrated pest management program for the potato psyllid and Ca. L. psyllaurous control on potatoes.
