Abstract:
The potato psyllid, Bactericera cockerelli Sulc, has recently been identified as a vector of Candidatus Liberibacter solanacearum, the putative causal agent of zebra chip potato disease. Zebra chip is causing millions of dollars in losses to the potato industry in the United States, Mexico, Central America, and New Zealand. Currently, the most effective strategy to manage this potato disease is to target the potato psyllid with insecticides. Effective management of this insect pest requires knowledge of its biology, ecology, geographic distribution, and population dynamics. Although it is well documented that the potato psyllid is common throughout the western United States, several reports have indicated that this insect pest does not occur in Washington and Oregon. However, this insect has recently been observed and collected in this region. Studies were conducted from 2005 to 2008 to document and determine the seasonal occurrence of the potato psyllid in this important potato growing region of the United States. The potato psyllid was monitored in untreated experimental potato plots at Moxee and Prosser in south central Washington. Contrary to previous reports, the potato psyllid was found to occur in Washington and appears to migrate into the region late in the growing season. Upon arrival in south central Washington in late July, this insect readily reproduces in potatoes and appears to have at least one generation a year. The origin of potato psyllids migrating to Washington has not yet been determined. Information from this study will help potato growers in Washington manage the potato psyllid to better prevent potential zebra chip outbreaks.
