CPHST: The Center for Plant Health Science and Technology

 Part of US Dept of Agriculture (USDA)  Assess risks exotic pests pose to food, fiber & environment  Identify pathways used by invasive species  Develop, adapt & support technology to detect, identify & mitigate impact of significant exotic pests

• Optimize existing pest management practices
• Develop new technologies: exclusion, detection survey &

management

• Support disease management / eradication programs
• Technical support for treatments & facility certification
• Training & Education

CPHST Agriculture Quarantine Inspection (AQI) Resources

• AQI Treatment Scientists at Otis, Gulfport,

Mission, Miami, Ft Collins, and Raleigh Labs

• Quality Assurance Unit in Raleigh
• Risk Analysis Lab in Raleigh
• Rearing facilities at Mission, Otis, Moss Landing,

Miami

• Collaborations with IAEA, Universities, Industry,

ARS, and others

Areas Where QPS MB Reduction May Be Achieved

• Target Logs, Tiles, Asparagus, Grapes, Flowers
• Substitute Washing and Brushing, Systems Approach,

Cold, Heat, or Irradiation

• Eliminating Need for Treatment through Risk

Assessment

• Increasing Accuracy of Gas Readings
• Sample Selection for Inspection of Propagative Material
• Increasing Detection Efficiency
• Better Regulatory Tracking and Tracing

Vacuum Steam Heating of Logs

Vacuum Steam Heat for Log Export

Specifying Full Loads for Asparagus Fumigations

Risk, inspection, and washing treatment studies on leprosis mite vector on citrus and grape

Risk of Establishment of Grape Mites and Leprosis Mites on Imported Fruit

Investigating Cut Flower Pathway for Lepidoptera from Colombia

Risk of Establishment of Copitarsia on Cut Flowers

Sulfuryl fluoride and methyl iodide treatments for snails on propagative plants and cut flowers

Cold Treatment for Bactrocera invadens in Imported Fruits

Development of infrastructure and capacity building for US export specialty crop irradiation treatments

• Effect of irradiation treatments on

commodity quality (blueberries and peaches pilot)

• Best configurations for irradiating

export commodities

• System for properly documenting

irradiation treatments for export commodities

• Transfer of technology to industry

Washing treatment for Citrus hystrix leaves and grapefruit for Asian citrus psyllid

Quantifying Inaccuracies in Fumiscope Readings Caused by Carbon Dioxide and Water Vapor

Quantifying Efficacy of Packinghouse Brushing of Fruit to Remove Armored Scales

Sample Selection for Inspection

• f Propagative Material

Z-nose Detection Technology

Z-nose Detection Technology

Efficacy of chlorine dioxide and hydrogen peroxide foam for decontamination of farm or military equipment

Alternatives for Discarding Quarantine Material

Identifying dead vs live scales, fruit fly larvae, pathogens via measuring respiration

2-D Barcode Tracking of Post- Entry Quarantine Plants

Post-Entry Quarantine Containment

Trace Element and Stable Isotope Analysis to Determine Origin of Fruits and Vegetables Intercepted in the Marketplace – A Pilot Project

Purpose and Objectives:

• Collaboration between CPHST Gulfport and Carson Watts

DHS laboratory, Savannah

• Build on existing DHS methods for classifying and

discriminating the geographic origin of commodities

• Assemble a geo-referenced data library of trace elements for

fresh commodities (mango) from multiple countries.

• Use the assembled data library to classify unknown origin

samples as either domestic or foreign source.

• Determine carbon and nitrogen contents and stable carbon,

nitrogen and oxygen isotopic compositions of commodities from various countries.

• Use stable isotope ratios to discriminate the geographic origin
• f commodities.

Conclusions

• FY10 AQI 15 QPS projects totaling more

than $500,000

• Building new AQI research lab in Miami to

be completed end of FY11

• FY11 AQI research funding will be down

because of decline in AQI user fees collected during recession
