Biocontrol Efforts Against Avocado Pests in California: A Review and Recommendations for Future Proactive Programs for Identifiable Invasion Threats

UC Riverside entomologist, Mark Hoddle, reviews introduced avocado pests and their biological control agents. Hoddle also surveys native avocado regions to document potential new invasive pests and their natural enemies. The project was funded by CDFA's Office of Pesticide Consultation & Analysis.

Methyl Iodide Economic Impact Study

The following UC Davis report, "Costs of Methyl Iodide Non-Registration: Economic Analysis," was produced under contract to CDFA's Office of Pesticide Consultation & Analysis. CDFA provided a preliminary version of the report to the Department of Pesticide Regulation (DPR) in December 2009, pursuant to the statutorily-mandated Memorandum of Agreement that governs the consultative relationship between the two agencies. The May 2010 final report differs from the preliminary version only by having used an improved method for estimating indirect impacts.

Emulsifiable Concentrate Alternatives Analysis

Under contract to CDFA's Office of Pesticide Consultation & Analysis (OPCA), fifteen UC Cooperative Extension specialists contributed to a study of alternatives to emulsifiable concentrate (EC) pesticides that produce high levels of volatile organic compound (VOC) emissions. It is hoped that the study, which focused on eight key crops, will assist the Department of Pesticide Regulation (DPR) in their effort to satisfy their mandated VOC emission-reduction goals in a manner that minimizes costs to California growers.

Interim Report: Biological Control of Arthropod Pests in California Agriculture

Researchers at UC Berkeley and Santa Clara University have produced a preliminary overview of the current status and future potential of biological control techniques in managing arthropod pests in California agriculture, a topic of rising importance due to persistent regulatory pressure on conventional insecticides. This ongoing study is being funded by CDFA's Pesticide Consultation office.

Report: A Critical Evaluation of Augmentative Biological Control

Two UC Berkeley entomologists employ a literature review to assess the feasibility of augmentative biological control as an alternative to conventional, insecticide-based pest control. The project was funded by CDFA's Office of Pesticide Consultation & Analysis.

Demand and Supply Elasticities for Major California Crops

Funded by the Pesticide Consultation office, this milestone UC Davis report provides the first systematic recalibration in a generation of demand and supply elasticities for the principal California crops. Elasticity measurements are the essential starting point for regulatory impact analysis, since they gauge the responsiveness of consumers and producers to price changes which regulations often impose through unavoidable production cost increases.

Report: The Economic Importance of Organophosphates in California

CDFA offers to interested readers this University of California, Berkeley, report analyzing the economic importance of organophosphate (OP) insecticides in California agriculture.

Effects of the January, 2008 CDPR Field Fumigation Regulations: Ventura County Case Study (April, 2009)

Funded by CDFA's Pesticide Consultation office, the following study by the UC Davis Department of Agricultural and Resource Economics examines potential impacts from DPR's fumigant VOC emissions cap in Ventura County.

Evaluating Scientific Institutional Capacity For Biological Control: A California Study As A Model Regional Network Assessment

Partially funded by CDFA's Pesticide Consultation office, this paper discusses staffing and research emphasis trends in eight institutions engaged in arthropod biological control in California from 1962-2006. The paper was published in the Proceedings of the Third International Symposium on Biological Control of Arthropods, Christchurch, New Zealand, February 8-13, 2009 (pp. 536-543).

Field Management Practices to Reduce Soil Fumigant Emissions

This is the final report of a multi-year USDA/ARS study (funded by the Office of Pesticide Consultation & Analysis) examining the feasibility of reducing airborne fumigant emissions through the employment of tarps, water seals, and organic soil amendments.

Olive Fruit Fly: Managing An Ancient Pest In Modern Times

Two University of California entomologists survey control methods for this key pest, with special emphasis on biological control. This research was partially funded by CDFA's Office of Pesticide Consultation & Analysis.

Organic Vineyard Management in California

As part of a larger, ongoing CDFA-funded study of the role of biological control in arthropod pest management, University of California experts report on the status of IPM in organic vineyards.

Reactivity of Volatile Organic Compounds Under Low NOx Conditions

This UC Davis study investigates an alternative regulatory approach to lowering pesticide volatile organic compound (VOC) emissions. The study was funded by CDFA's Office of Pesticide Consultation & Analysis.

Socio-Economic Analysis of the North American Commercial Natural Enemy Industry and Implications for Augmentative Biological Control

California growers practicing augmentative biological control rely on the commercial insectary business for natural enemies. Researchers at Santa Clara University and UC Berkeley report on their analysis of this industry as part of the CDFA Office of Pesticide Consultation & Analysis biological control project.

The Decline of Public Interest Agricultural Science and the Dubious Future of Crop Biological Control in California

As part of CDFA's ongoing study (funded by the Office of Pesticide Consultation & Analysis) of the future prospects for utilizing biological control methods to manage arthropod pests in California production agriculture, this paper analyzes historical trends in institutional support for biological control research and implementation.

Vineyard Managers and Researchers Seek Sustainable Solutions For Mealybugs, A Changing Pest Complex

UC Berkeley entomologist Kent Daane and others review vineyard mealybug pests and their natural enemies, discussing current trends in biological control and potential new research. The project was partially funded by CDFA's Office of Pesticide Consultation & Analysis.
