Special Sessions:

Thousand Cankers Disease: A Threat to Eastern Black Walnut Throughout Its Native Range and Beyond

Tuesday, August 7; 8:30 – 11:30 a.m.

Organizers: Inga Meadows, Ministry of Primary Industries, Auckland, New Zealand.; Matt Kasson, Pennsylvania State University, University Park, PA, U.S.A.
Section: Diseases of Plants
Sponsors: Forest Pathology; Emerging Diseases and Pathogens; Vector-Pathogen Complexes; Epidemiology
Financial Sponsors: Walnut Council; Walnut Council Foundation
Decline and mortality of walnut trees (Juglans spp.) have been observed in the last decade throughout the western United States and, more recently, in the eastern United States. The disease complex, thousand cankers disease (TCD), is caused by the fungus Geosmithia morbida and vectored by the walnut twig beetle, Pityophthorus juglandis. TCD has increased concerns of the health of black walnut and its viability as a commercial product. This session will emphasize current knowledge of TCD and highlight research gaps.

8:30 a.m. The distribution and impact of thousand cankers disease in walnut species in the western United States. N. TISSERAT (1). (1) Colorado State University, Fort Collins, CO, U.S.A.
9:00 a.m.  From discovery to regulation: A pathologist’s perspective of thousand cankers disease in eastern United States. M. WINDHAM (1). (1) Department of Entomology and Plant Pathology, University of Tennessee, Knoxville, TN, U.S.A. 
9:30 a.m.  Evolution, diversity, and ecology of the genus Geosmithia with emphasis on G. morbida. M. KOLARIK (1). (1) Institute of Microbiology of the Academy of Sciences of the Czech Republic, Prague, Czech Republic 
10:00 a.m.  Break 
10:15 a.m.  Life history of the walnut twig beetle, Pityophthorus juglandis, and its association with Geosmithia morbida, causal agent of thousand cankers disease in the United States. S. J. SEYBOLD (1). (1) USDA Forest Service, Pacific Southwest Research Station, Davis, CA, U.S.A. 
10:45 a.m.  Thousand cankers disease: A recently emerging disease of eastern black walnut in the eastern United States. G. J. GRIFFIN (1). (1) Virginia Tech, Blacksburg, VA, U.S.A.

“Left of Boom!” Information: Form, Content, and Use in Epidemic Prediction

Wednesday, August 8; 8:30 – 11:30 a.m.

Organizers: Neil McRoberts and Carla Thomas, University of California, Davis, CA, U.S.A.
Section: Ecology and Epidemiology
Sponsors: Epidemiology; Regulatory Plant Pathology; Diagnostics; Emerging Diseases and Pathogens; Forest Pathology; Crop Loss Assessment and Evaluation
When considering epidemic timelines, events prior to an outbreak are considered to be to the left of the event (the Boom!). New approaches often use textual, qualitative information from informal nonreviewed sources and have potential to be used for prediction in similar ways to quantitative data. This session will examine new approaches and relate them to traditional approaches to disease detection and prediction and highlight common information across these methods using case studies.

8:30 a.m.  Information in multiscale epidemiological models. C. C. MUNDT (1), P. Skelsey (2), P. S. Ojiambo (3), K. A. Garrett (2). (1) Oregon State University, Corvallis, OR, U.S.A.; (2) Kansas State University, Manhattan, KS, U.S.A.; (3) North Carolina State University, Raleigh, NC, U.S.A.
9:00 a.m.  Transportation grids as early indicators and warning—The use of census and travel data for prediction of disease incursions. T. R. GOTTWALD (1), T. D. Riley (2), M. S. Irey (3), S. R. Parnell (4). (1) USDA-ARS, Fort Pierce, FL, U.S.A.; (2) USDA APHIS PPQ, Orlando, FL, U.S.A.; (3) United States Sugar Corp., Clewiston, FL, U.S.A.; (4) Rothamsted Research, Harpenden, United Kingdom 
9:30 a.m.  Emergence of unified concepts of disease in textual surveillance data. C. S. THOMAS (1), N. P. Nelson (2). (1) University of California-Davis, Department of Plant Pathology, Davis, CA, U.S.A.; (2) Georgetown University Medical Center, Washington, DC, U.S.A.

Right of the Boom: Deciding to Act, React, or Let Go in a Fluid Data Environment

Wednesday, August 8; 1:00 - 4:00 p.m.

Organizers: Lawrence Brown, USDA\APHIS\PPQ, Raleigh, NC, U.S.A.; Neil McRoberts, University of California, Davis, CA, U.S.A.
Section: Ecology and Epidemiology
Sponsors: Crop Loss Assessment and Risk Evaluation; Epidemiology; Regulatory Plant Pathology; Diagnostics; Emerging Diseases and Pathogens; Forest Pathology
The complimentary session “Left of the Boom!” considers prospects for improved disease forecasting and detection. However, the future will involve outbreaks of quarantine pests that impose biological and economic losses on agriculture. This session explores frameworks and measures for decision support in regulatory agency decision-making to the right of the Boom! (after an outbreak). It combines views from practitioners, researchers, and analysts on future directions for better regulatory plant pathology.
