Research Project: Management of Zebra Chip to Enhance Profitability and Sustainability of U.S. Potato Production

Location: Fruit and Vegetable Insect Research

Project Number: 5352-22000-020-10
Project Type: Reimbursable

Start Date: Sep 01, 2010
End Date: Jun 30, 2014

Objective:
Increasing the understanding of the zebra chip potato disease vector biology, vector-pathogen interaction, and the epidemiology of the disease.

Approach:
Assess the role of the potato psyllid in zebra chip potato disease by: 1) conducting insect transmission studies under laboratory conditions to determine liberibacter acquisition and inoculation access time required for the potato psyllid to effectively transmit the bacterium and induce zebra chip, 2) determining the impact of zebra chip on different plant growth stages under controlled field cage conditions, 3) determining density of potato psyllid required for this insect pest to effectively cause zebra chip, 4) assessing environmental conditions that may influence ZC symptom expression, including temperature, relative humidity, and light intensity, and 5) screening potato breeding material for zebra chip. Documents Reimbursable with Texas A&M (SCRI). Log 44012.
