Introduction

Planning Process and Plan Development

ARS scientists and administrators met with customers, stakeholders, and partners at a series of workshops that were designed to discuss major issues and priorities for the Crop Protection and Quarantine National Program.  These workshops were as follows:  Stored Product Entomology, Manhattan, Kansas, October, 1999; Exotic Pests, Honolulu, Hawaii, January, 2000; Weed Science, Dulles, Virginia, July 2000; and Crop Protection and Quarantine, San Diego, California, October, 2000.  Based on these in-depth exchanges, the research components summarized above were identified for this National Program. Writing teams composed of ARS scientists and members of the National Program Staff were formed to develop planning documents that will provide a framework for ARS research. 

Postharvest, Pest Exclusion, and Quarantine Treatment,
Stored Product Entomology Workshop
Ramada Plaza Hotel, Manhattan, Kansas
October 12 - 14, 2000

The Stored Product Insects subcomponent of National Program 304 was held in Manhattan Kansas, October 12-14, 2000. Approximately 35 customers, stakeholders, and research partners joined 30 ARS scientists and research managers to discuss high priority issues and research needs of this important program subcomponent.  The results of the workshop sessions have been used to develop the action plan for the Crop Protection and Quarantine National Program. 

Exotic Pest Program Workshop
The Ilikai Hotel, Honolulu, Hawaii

January 24 - 26, 2000

The Pests of Quarantine Significance (Exotic Insect Pests) Program subcomponent of National Program 304 was held in Honolulu, Hawaii, January 24 - 26, 2000.  Approximately 120 customer/client/research partners, including representatives from 11 countries and territories joined 33 ARS scientists and research managers to discuss high priority issues and research needs of this important program subcomponent. Because much of the ARS research program in this area deals with pests either quarantined by the United States or our trading partners, the Animal and Plant Health Inspection Service (APHIS) co-sponsored the workshop.  The results of the workshop sessions have been used to develop the action plan for the Crop Protection and Quarantine National Program. 

Weed Science Workshop
Holiday Inn Washington Dulles
Dulles, Virginia

July 10 - 13, 2000

During the three-day customer oriented workshop for the weed science component of the Crop Protection and Quarantine National Program (NP 304), 73 customers from around the nation were involved in a progressive series of meetings and discussions that alternated between the general audience and smaller breakout groups.  Only customers participated in the discussions.  ARS administrators and scientists facilitated these deliberations, but otherwise did not contribute to them unless asked specific questions by customers to help clarify ARS’ roles in various research and administrative activities.

The result of these discussions was a series of 16 recommendations by the customers for ARS to consider, and these are listed below in non-prioritized order.  The first recommendation was for ARS to establish a new national program solely devoted to weed science.  This represented an administrative proposal, whereas the remaining 15 recommendations embodied researchable topics.  The results of the workshop sessions have been used to develop the action plan for the Crop Protection and Quarantine National Program. 

Crop Protection and Quarantine Workshop
The Hanalei Hotel, San Diego, California 

October 30 – November 2, 2000

A National Program Workshop for Crop Protection and Quarantine (NP 304) was held jointly with the Crop Production National Program (NP 305) in San Diego, California on October 30 – November 2, 2000, to obtain input from ARS customers, stakeholders, and partners on high priority crop protection problems and research needs.  Approximately 90 non-ARS attendees joined 80 ARS scientists and research managers to discuss high priority issues and research needs.  Participants were broken out into a number of broad commodity oriented sessions covering: (1) fiber, oilseed, and oil crops, (2) grain and forage, (3) vegetables, (4) ornamentals and turf, (5) tree fruits and nuts, (6) small fruits, and (7) citrus/tropical/subtropical fruit and sugar.  An additional session with breakout groups was held for all participants that focused on a number of overarching issues covering (1) sustainable agriculture, (2) economics of production, (3) greenhouse, (4) rganic farming, (5) Integrated Pest Management (6) small farms, and (7) regulatory mandates.  The results of the workshop sessions have been used to develop the action plan for the Crop Protection and Quarantine National Program.

Weed Science Workshop

Crop Protection and Quarantine National Program
Weed Science Workshop (Holiday Inn Washington Dulles
1000 Sully Road, Dulles, Virginia,  July 10-13, 2000)

During the three-day customeroriented workshop for the weed science component of the Crop Protection and Quarantine National Program (NP 304), 73 customers from around the nation were involved in a progressive series of meetings and discussions that alternated between the general audience and smaller breakout groups.  Only customers participated in the discussions.  ARS administrators and scientists facilitated these deliberations, but otherwise did not contribute to them unless asked specific questions by customers to help clarify ARS’ roles in various research and administrative activities.

The result of these discussions was a series of 16 recommendations by the customers for ARS to consider, and these are listed below in non-prioritized order.  The first recommendation was for ARS to establish a new national program solely devoted to weed science.  This represented an administrative proposal, whereas the remaining 15 recommendations embodied researchable topics.

Customers’ list of high priority issues for ARS (not in order of priority)

  •  Establish a Weed Science National Program
  • Increase research in weed and seed biology, ecology and physiology, including weed/crop interactions
  • Increase research in integrated weed management in all habitats and ecosystems
  • Study invasiveness of plant species
  • Incorporate risk assessment and environmental impact in ARS weed research programs, including non-target impact and threatened & endangered species.
  • Increase biological control of weeds, emphasizing long-term, post-release evaluation of biological control agents on target and non-target species
  • Increase research on herbicides, including herbicide-resistant plants, application technology, resistance management, IR-4 and Food Quality and Protection Act chemistries and natural products
  • Increase cultural weed control, including restoration, and mechanical weed control
  • Study prevention, early detection and eradication as part of a “Rapid Response Team” with Federal, State, Local and international partners
  • Increase weed science research in biotechnology and genomics, including crop modification, weed population genetics, molecular diagnostics and gene markers
  • Conduct weed science research in support of organic growers, ornamentals, MeBr, small farms, and sustainable agriculture
  • Develop emerging weed science technologies, including precision agriculture, long-term, high-risk research, improving/optimizing current technology, and remote sensing/spectral imaging, and nanotechnology
  • Incorporate economics in ARS weed science programs
  • Increase partnerships to collaboratively develop weed science programs, and to exchange information and encourage technology transfer to end users
  • Increase training and education in weed science
  • Increase research in weed taxonomy and systematics

At the final general discussion, each customer was allowed five votes for any issues that he or she believed to be the highest priority topics on which ARS should focus its energies.  An individual customer could use all five votes for a single issue or could disperse those votes among two to five issues as desired.  The number of votes for each topic was counted, which permitted a means of ranking the topics.  In a similar manner, ARS employees at the workshop also were allowed to vote for the same 16 topics, but they did so separately from the customers.

The highest priority topic for both the customers and the ARS scientists was the establishment of a separate national program for weed science.  Again, creation of such a program is an administrative matter and does not represent a researchable topic that can be pursued by ARS scientists.

The 15 remaining topics are researchable in one form or another.  The relative rankings of these topics are depicted in the following two charts, the first for customers and the second for ARS scientists.  The abscissa (x-axis) of each histogram represents the rank-order of the topics according to the customers’ voting results.

The rankings of the two groups (customers and ARS scientists) show broad agreement, as can be seen in the following chart where the relative rankings of the two groups are plotted against one another.  The major disparity between the groups is that customers ranked increased research on herbicides more highly than biological control of weeds, whereas the opposite was true for ARS scientists.  Otherwise, the two groups were in surprising unanimity in their perceptions for highest priority research needs.

 


Exotic Pest Program Workshop

Exotic Pest Program Workshop
Ilikai Hotel, Honolulu Hawaii

January 24-26, 2000

The following areas were identified by the participants as priorities for research. ARS worked with APHIS to consolidate the list, to inventory current research and regulatory activity, and to prepare an action plan to accommodate as many of these issues as possible.

I.  Detection and delimitation

A.   Development and evaluation of trapping devices and "hardware"

  • Improved lures and formulation
  • Improve current traps and develop functional traps for "new" pests
  • Look at latest technologies from other disciplines; e.g., biotechnology
  • Automated "counters" and data entry mechanisms
  • Longevity and weathering of attractants; especially increased longevity of TML dispensers in Florida (3 to 6 wks)
  • "Less complicated" (than 3-component lure) female Medfly trap
  • Eliminate insecticides from Bactrocera traps
  • Sticky traps for "hard-to-capture" insects (those that walk out of Tanglefoot or adhesive paper)

B.   Design and evaluation of detection systems

  • Assess the sensitivity of detection systems (what does it mean when no flies are captured?)
  • Determine "effective radius" for trap/lure combinations
  • Optimize protocols for detection of exotic pests and certification of pest-free zones with reference to exporting commodities; i.e., optimal trap density, trap-servicing intervals, trap relocation intervals, cost-benefit, etc.
  • Figure how to "weed out" false positive detections that could otherwise shut down exports and/or create unnecessary quarantines, deployment of delimitation programs, etc.
  • Develop model systems using field studies, statistical analyses, computer models, expert systems, etc. with key species such as a tephritid, Anoplophora and a lepidopteron such as a lymantriid
  • Incorporate behavioral ecology, regional factors, etc., into trapping strategies
  • Evaluate effects of environmental variables on effectiveness of detection traps
  • Determine/reassess high-risk areas for trapping

C.  Identification of detected organisms

  • Molecular diagnostics to differentiate closely related species and their endosymbionts
  • Systematics and identification of "problem" taxa (e.g., Heliothis and others)
  • Source of origin determination

D.  Develop a comprehensive database of detection technologies for potentially invasive species

  • Known attractants and/or other aspects of biology relevant to detection and delimitation of a wide variety of exotic pests
  • Known attractant dispensers, traps, or other relevant detection technology, by species (include commercial availability of detection technology)
  • Information should ideally be readily accessible; i.e., on the Internet
  • Include information on cross-attractancy
  • Database should be developed thru international partnerships (e.g., USDA, IAEA, etc.)
  • Mine the database to identify critical gaps in the availability of detection technology

E.  Develop detection systems other than "traps"

  • Remote sensing for plant diseases, wood-boring pests (Anoplophora), etc.
  • Acoustic devices
  • Ultrasound (AQI)
  • Electronic sniffers (AQI)
  • X-rays
  • Immunological techniques (e.g., ELISA)
  • Radar

F.  Economic considerations in trapping programs

  • Cost of lures and traps
  • Effects on total program costs
  • Cost/benefit analysis (trapping costs vs. reduced cost of eradication, control, quarantine, etc.

G.  Invasion biology

  • Ecology of the pest
  • Pathway analysis for prediction and preparation for introductions
  • Behavior of pest in "home" environment and predictions for new (invaded) environment
  • Alert for "next" target pest

H.  Detection and delimitation – additional high-priority issues

  • Develop identifying markers for sterile insects with genetic markers using transformation, paratransgenesis, etc.
  • Foreign research on potential pests before they invade; population dynamics and other aspects of ecology and behavior, detection technology, etc.
  • Develop detection technologies for insects other than moths and fruit flies, e.g., Heteroptera (and Cerambycids)
  • Physiological significance of detected organisms (what is the organism’s age, mating status, etc., and what does that tell us about the population it came from?); eye pigment vs. age, sperm-head length of sterile vs. wild
  • Prioritization of trapping activities – based upon AQIM data, pest "intelligence" risk ratings
  • Traps and protocols for delimitation – "short-term" specific objective, customize as needed; high potency, may be sex-specific, need better understanding of biology and ecology
  • Systematic neural physiological investigations to improve pheromones and parapheromones
  • Trapping QC - consistent performance, storage, longevity

I.  Current pests/programs where improved detection and delimitation technology is critically needed

  • Exotic fruit flies [Non-programmatic (Anastrepha, Bactrocera, others), Mexfly, Medfly]
  • Anoplophora spp.
  • Citrus canker
  • Citrus leafminer
  • Hidden (cryptic) pests
  • Plum pox
  • Glassywing sharpshooter
  • Pink hibiscus mealybug

J.  Management and related issues

  • Development of emergency response capabilities in ARS – currently ARS is slow to respond to emergency needs. It was suggested that there be paired ARS/APHIS teams ready to respond
  • More program support/data analysis
  • Analysis of intercepted data, focus targeting, disseminate information in a timely fashion
  • Avoiding unfocused research demands (better traps and lures for fruit flies)
  • Develop systematic approach to collaborations between basic science and implementation.
  • Bottom-up research development from basic research to applied research
  • More quickly utilize new technologies on old problems
  • Focus on a variety of pests (weeds, pathogens, nematodes, etc.)

IV.  FUNDAMENTAL BIOLOGY

A.  Genetics (molecular biology/behavior)

  • Genetic sequencing pests
    • Very little information on genome of Medfly (template for other tephritids?)
    • Identify and sequence specific genes of interest, e.g., genes that influence behavior, etc.
    • Medfly as focus
    • Tribolium may serve as template for coleopterans, sequencing information is available for Tribolium
  • Maintenance of strains
    • Cryopreservation
    • Traditional rearing, slowing colonies down
    • Characterize strains/biotypes
  • Transgenesis Research
    • Which genes should be targeted for transgenesis?
  • Goals and applications:
    • Sexing strains
    • Autocidal control
    • Conditional lethal genes
    • Reduce fecundity/fertility
    • Markers for released insects
    • Behavioral genes (host/pheromone odor receptors, semiochemical production; could be beneficial for SIT or used to mess up wild insects)
    • Design resistance strains for beneficials
    • Need to identify additional molecular vectors for transgenesis, e.g. Wolbachia system, virus (i.e., other means of transgenesis)

B.  Systematics

  • Traditional Systematics
    • Develop systems for rearing out intercepted material for taxonomic purposes
  • Molecular Systematics
    • Molecular identification techniques may also help to id larvae on site without rearing, and avoid rearing/transport of live organisms.
    • Characterize strains/biotypes
    • To determine genetic basis of phylogenetic relationships (e.g., identify species complex, closely related species)
    • Increase emphasis for systematics and diagnosis
    • Diagnostic kits for on-site identification (don’t forget traditional systematics)
    • Systematics of endosymbionts/associated microbes as a taxonomic tool or as site for molecular markers

C.  Ecology and behavior

  • Interrelationships among microbial, plants, insects (need endosymbionts lab)
    • Symbionts, associated microbes
    • Improve fitness of laboratory-reared insects as diet additive
    • Develop lures based on microbial-produced volatiles
    • Microbes (plant disease) vectored by insects
    • Bugs and guts, interrelationships
    • Study of endosymbionts/associated microbes in exotic pests
  • Determine best bait formulations in different agroecosystems
  • Develop protocol for bait handling
  • Determine factors that influence bait effectiveness, e.g. environmental factors, formulation, storage
  • Determine thresholds for population establishment (triggers, quarantine, regulatory issues) for decision making (2 flies or 200 flies?)
  • Obtain as much information as possible from each detection, e.g., pathway of origin, gut contents, physiological state - pure forensic entomology
  • Host plant interactions
    • Host finding, development of attractants from host material
    • Host suitability
    • Efficiency of invasive species as vectors of plant diseases for predictive purposes
  • Behavior of SIT insects, over flooding ratio, life history parameters of the SIT insects (e.g., how long do they live, dispersal, mating efficiency), biotype of SIT insects
  • Life cycle developmental models for invasive species
  • Studies of closely related endemic species as models for exotic pest (e.g., walnut husk fly for Medfly)
  • Determine risk of introduction and establishment of potential pests. Develop database that includes analysis of invasion pathways, predictions on establishment patterns and distributions in new environment, data on distribution in home/endemic environments, determine environmental parameters, analyze climatic data, plant/host relationships

D.  Physiology and biochemistry

  • Physiology of mating and reproduction
  • Behavioral physiology, specifically Coleoptera - representative of invasive species for host finding and mating behavior
  • Sensory physiology, e.g. as related to host finding
  • Nutritional physiology related to microorganisms and symbiosis and its impact on baits, attractants
  • Need novel delivery mechanism for neuropeptides
  • Physiological effects of rearing, cold tolerance, irradiation
  • Increase neural physiology research capacity (behavior, pheromone receptors)
    • Methods to modify insect response to pheromone
    • EAG analysis

E.  Other non-research needs

  • Bioinformatics
    • Post information on the web
    • Link to Universities as a source for collaborators, e.g., universities may have bioinformatics as a area of research
    • USDA/ARS should provide an Internet site to act as repository/clearinghouse for research results
    • Exotic pest facilities (p20)
  • Cooperative agreements - locales where exotics can be studied
  • Regulatory need: expanded availability to rear exotic pests under quarantine for other researchers (APHIS issue)
  • Expertise base at non-traditional sites (non-agricultural universities)
  • Regulatory need - complete regulatory process for permits for release of transgenics into environment
  • Electronic imaging for systematic analysis, information transfer
  • Onsite port rearing or quarantine facility so that intercepted larvae coming through that site of entry can be reared to adult for taxonomic identification, may only need to rear through one time to get adult for identification.
  • Problems encountered with transport of potential pest from port to quarantine facility
