Temporal and Spatial Analysis of Potato Psyllid Haplotypes in the United States
Environmental Entomology, 2013The potato psyllid, Bactericera cockerelli (Sulc) (Hemiptera: Triozidae), is an economically important pest of potato (Solanum tuberosum L.) crops across the western and central United States, as it is known to cause psyllid yellows disease and to transmit the bacterium that causes zebra chip disease. Recent genotyping of B. cockerelli collected during

Molecular detection of phytoplasmas in potato psyllids in ecuador
Phytopathogenic Mollicutes, 2021Since the potato purple top appeared and the potato psyllid was reported in Ecuador, crop losses have been significant. So far, phytoplasmas enclosed in two ribosomal groups (16SrI-F, 16SrII) and ‘Candidatus Liberibacter solanacearum’ were molecularly identified in symptomatic potato plants.

The potato psyllid, Bactericera cockerelli (Å ulc)
2023Bactericera cockerelli, a psyllid, is a major agricultural pest affecting potatoes, tomatoes and other crops through feeding damage and transmission of the bacterial pathogen Liberibacter solanacearum, which causes zebra chip disease. This pest, originating from the Western USA, Mexico and Central America, poses a threat in its native regions and in ...

Insecticide and Acaricide Tests, 1979
Abstract Potato seed pieces were planted Feb 24‘78 in Laveen clay loam on 34-inch row spacing, using a John Deere 2-row planter. Plots were 30-feet long, 4 times in a randomized block design. Granular phorate was applied at planting time using a Gandy dry insecticide applicator mounted on the potato planter.

Resistance of Selected Potato Genotypes to the Potato Psyllid (Hemiptera: Triozidae)
American Journal of Potato Research, 2013The characterization of resistance of selected potato, Solanum tuberosum L., breeding clones to the potato psyllid, Bactericera cockerelli (Sulc) (Hemiptera: Triozidae) was investigated. Antixenosis was assessed in choice tests in which a single plant of each genotype was placed inside a rearing cage, where 60 female psyllid adults were released and ...

Physiological effects of psyllid (Paratrioza cockerelli) on potato
American Potato Journal, 1985Feeding by psyllid nymphs causes “Psyllid yellows,” a characteristic yellowing of shoots which results in a dramatic loss of tuber yield. If psyllid infestation is not controlled, the onset of shoot yellowing and growth reductions can occur within two weeks. When insecticides are applied after yellowing, recovery of plants often is not complete.

Bactericera cockerelli (tomato/potato psyllid).
2021Abstract B. cockerelli is one of the most destructive potato pests in the western hemisphere. It was recognized in the early 1900s that B. cockerelli had the potential to be an invasive and harmful insect, particularly in western United States and Mexico (Šulc, 1909; Crawford, 1914; Compere, 1915; 1916; Essig, 1917). By the 1920s and

Seasonal Dispersal of the Potato Psyllid,Bactericera cockerelli, into Potato Crops
Southwestern Entomologist, 2014Abstract. Potato psyllid, Bactericera cockerelli, vectors the bacterium associated with the devastating zebra chip disease of potato, Solanum tuberosum L., in the United States, Mexico, Central America, and New Zealand. A seasonal pattern of appearance of the psyllid in crops from southern to northern regions of the United States is well documented ...

Sampling and interpretation of psyllid nymph counts in potatoes
Entomologia Experimentalis et Applicata, 2012AbstractDevelopment of effective management practices for insect pests relies heavily on sampling methods to accurately detect and quantify emerging populations. Herein we describe a novel method to extract and count nymphs of potato psyllid, Bactericera cockerelli (Šulc) (Hemiptera: Triozidae), from leaves in commercial fields of potato, Solanum ...
