Exotic Pests and Diseases

Asian Citrus Psyllid Management
The deadly huanglongbing is spreading towards California and threatens commercial citrus production.  This web site is designed to show citrus growers where the Asian citrus psyllid and the HLB disease are located.  Since there is currently no cure for the disease, the best management strategy is reducing the psyllid vector with insecticides.  This web site will also provide a list of the ACP-effective insecticides, information about the best timing of their use, strategies for treatment and cost projections. 

Aggregate Costs and Benefits of Government Invasive Species Control Activities. Daniel A. Sumner, Henrich Brunke and Marcia Kreith. (pdf, 163kb, September 2006.

The Payoff to Public Investments in Pest-Management R&D: General Issues and a Case Study Emphasizing Integrated Pest Management in California

(December 2005, pdf) John D. Mullen, Julian M. Alston, Daniel A. Sumner, Marcia T. Kreith, and Nicolai V. Kuminoff.  Using California as a case study, this paper describes the post–World War II history of agricultural pest-management technology, documents the development and use of chemical pesticides, describes the role of public research, and measures the benefits and costs for five important commodities, emphasizing integrated pest management.

How Serious is the Threat of Mad Cow Disease?
A video seminar held February 5, 2004 at UC Davis
On December 23, 2003 the U.S. was shocked by the news of a case of Bovine Spongiform Encephalopathy (BSE or more commonly mad cow disease) found in a dairy farm in Washington state. To provide information about the implication of this event, AIC's Daniel Sumner and José Bervejillo and Dean Cliver of the UC Davis School of Veterinary Medicine participated in a seminar discussion sponsored by the UC Davis Institute of Governmental Affairs. Cliver reviewed the basics of the BSE and provided an assessment of human and animal health consequences. Sumner and Bervejillo assessed the economic impact of this first case of mad cow disease in the U.S. and the implications of the new federal regulations on the livestock industry.

Returns to University of California Pest Management Research and Extension. Overview and Case Studies Emphasizing IPM. John D. Mullen, Julian M. Alston, Daniel A. Sumner, Marcia T. Kreith, and Nicolai V. Kuminoff, May 2003.
University of California Agricultural Issues Center, ISBN: 1-885976-09-7, ANR Publication 3482.Exotic Pests & Diseases: Biology and Economics for Biosecurity, edited by Daniel A. Sumner, emphasizes the importance of policy measures to protect against the introduction and spread of exotic pests and diseases and provides needed analysis of the policies on this important topic. Detailed cases include foot and mouth disease, red imported fire ants, citrus canker and 11 other important exotic pests and diseases. This book grew out of a large interdisciplinary project at the University of California Agricultural Issues Center and includes ten interdisciplinary case studies which focus on specific pests or diseases representing a range of threats to U.S. agriculture, wildlands as well as the urban landscape, and possible government responses to these threats. The book is addressed to students, practitioners, and academics in the fields of economics, veterinary medicine, plant pathology, entomology and agriculture, as well as policy makers, state and federal regulators, government officials, and others with an interest in pest management. 326 pp., 7 x 10, hardcover, illustrations, ISBN 0-8138-1966-0, Iowa State Press, 2003.
