Introduction

The National Plant Diagnostic Network (NPDN) was formed in June 2002 in response to agricultural biosecurity concerns. The Southern Plant Diagnostic Network (SPDN) is one of five regions within the NPDN. Member states or U.S. territories of the SPDN include: Alabama, Arkansas, Florida (UF, regional center), Georgia, Kentucky, Louisiana, Mississippi, North Carolina, South Carolina, Tennessee, Texas, Puerto Rico, Virginia, and the U.S. Virgin Islands. The mission of the NPDN/SPDN is to enhance agricultural security and assist in protecting the U.S. from intentional or unintentional exotic pest introductions. Numerous endemic, introduced, and exotic species of scale and mealybug insects (Hemiptera: Coccoidea) threaten agriculture in the southern U.S.

National taxonomic specialists will interactively lead participants through family, genus, and some species-level identification.  Proper preparation of slide-mounted specimens will also be an emphasis of the training.  Following training, participants should be comfortable with slide-mounting as well as general identification and use of taxonomic keys for scale insects (Coccoidea).   

Who Should Attend?

General entomology diagnostician and extension specialists, researchers, and other regulatory identifiers interested in scale insect identification should attend. Enrollment will be limited to 25 participants, and will initially target local attendees. Others may be allowed to attend on a space available basis. The course material will be advanced, and is not suitable for individuals without an entomological background or related experience. Questions regarding your approval to attend the conference may be directed to Amanda Hodges at achodges@ufl.edu or David Jenkins David.Jenkins@ars.usda.gov .  The following groups would benefit from the workshop:

  • General Entomology Diagnosticians
  • Extension Specialists
  • Research Specialists in Puerto Rico and the Caribbean Region
  • Federal and/or State General Insect Identification Specialists

Benefits of Attending

Upon completion of the workshop, you will:
  1. Be more familiar with common and exotic target scale and mealybug pests for Puerto Rico and the Caribbean Region.
  2. Be able to prepare a slide-mounted specimen.
  3. Become more familiar with key morphological characters for family and genus-level identification of pest scale insects of concern.
  4. Be familiar with the use of digital diagnosis to assist in sample screening.
  5. Know specialists that can be contacted if you suspect that you have an exotic specimen.
  6. Understand sample submission protocols regarding exotic pests of concern.

Participants will receive the following educational materials:

  1. CD-ROM: 2007. Scale Insects: Identification tools, images, and diagnostic information for species of quarantine significance by D.R. Miller, A. Rung, G.L. Venable, and R.J. Gill.
  2. Field Guide Booklet. 2008. Mealybugs & Mealybug Look-Alikes of the Southeastern U.S. by A. Hodges, G. Hodges, L. Buss, and L. Osborne.
  3. Additional training handouts.
  4. List of useful resources for further pest identification.

Workshop Topics

Field and slide-mounted identification of scale insects (Coccoidea) will be covered.  Details on preparation of proper slide-mounted specimens will also be included.  Due to their small size, appropriate slide-mounting techniques are essential to confirmatory diagnosis of mites.  Gender and/or life stage recognition is also an important component of identification. 

Scale insects (Coccoidea) contain over 20 families, 1200 genera, and 7300 species. Workshop participants will not gain a comprehensive knowledge of scales during the training, but will be better able to utilize available resources to recognize common pests and determine if further confirmatory identification is warranted. Genera and species level identification examples will be focused on pests within the following common families:

  • Mealybugs (Pseudococcidae)
  • Soft Scales (Coccidae)
  • Armored Scales (Diaspididae)

Workshop Instructors

Dr. Gregory Hodges

Greg Hodges photoGreg received his M.S.from Auburn University (1996) and his Ph.D. from the University of Georgia (2001). Taxonomic research during both of his graduate degrees included a focus on the immature or “crawler” life stage of soft scales (Coccidae). Greg also had the opportunity to conduct applied/extension-oriented research relating to scale insect problems on ornamental plants and fruit trees during his graduate and brief post-doctoral employment at the University of Georgia. During 2002, Greg began working for the Florida Department of Agriculture, Division of Plant Industry (FDACS-DPI) and his taxonomic identification responsibilities include the Coccoidea and Aleyroidea. In addition to taxonomic studies relating to these areas, Greg continues to work on development of scale and whitefly user-friendly, field-oriented keys or other guides. During July of 2008, Greg was promoted to Bureau Chief of Entomology, Nematology, and Plant Pathology for FDACS-DPI.

Dr. Michael Williams

Mike Williams photoMike received in M.S. (1969) in entomology/botany and his Ph.D. (1972) in entomology from Virginia Polytechnic Institute and State University. Mike worked as an assistant state entomologist for the Maryland Department of Agriculture from 1971-73.  Mike has been employed by Auburn University since 1973. His taxonomic research interests have focused on the biosystematics of scale insects, with a particular interest on soft scales (Coccidae). Other scale-related research interests have included species identification and distribution in Central and South America; host plant resistance; the coevolution of scales and their host plants; biology and control of ornamental plant pests; and integrated pest management tactics.  In addition to mentoring graduate students, Mike’s teaching responsibilities have included general insect morphology, systematic entomology, advanced insect morphology and development, and special problems in entomology.
