'Homoptera' Workshop

Specialized Taxonomic Training for Entomologists

December 9-11, 2004 Gainesville, FL



The National Plant Diagnostic Network (NPDN) was formed in June 2002 in response to agricultural biosecurity concerns following the terrorist attacks of September 11, 2001. 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, and Virginia. 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 ‘Homoptera’ threaten agriculture in the southern U.S.

National taxonomic specialists will interactively lead participants through family, genus, and species level identification. Specialists will generally provide brief, overview presentations to pest groups. The majority of participant time will focus on hands-on identification of specimens.

Who Should Attend?

General entomology diagnostician and extension specialists in the southern region interested in ‘Homoptera’ identification should attend. Enrollment will initially be limited to two participants per SPDN state or territory. Each state’s representation will be determined by their SPDN entomology representative. Any remaining spaces will be filled on a first-come, first-served basis. The following groups would benefit from the workshop:

  • General Entomology Diagnosticians

  • Extension Specialists

  • Graduate Students focusing on ‘Homoptera’ or Taxonomy

  • Federal and/or State General Insect Identification Specialists

Six Ways You Benefit from Attending

Upon completion of the workshop, you will:

  1. Enhance your understanding of the morphology of ‘Homoptera’ groups covered and subsequently, be able to use taxonomic keys more effectively.

  2. Be able to use the course manual provided during the workshop for identification of pests in your state.

  3. Be more familiar with family, genera, and species of ‘Homoptera’ in the southern region of economic concern and their current distribution.

  4. Learn about exotic ‘Homoptera’ threats to the southern region, and be able to more effectively recognize a potentially exotic sample.

  5. Know the specialists that can be contacted if you suspect that you have an exotic specimen.

  6. Enhance your taxonomic identification skills through interacting with ‘Homoptera’ specialists.

Workshop Instructors  

Dr. Christopher Dietrich: Chris received his Ph.D. in entomology from North Carolina State University in 1990. A majority of his taxonomic research has focused on phylogenetic analysis and revision of the taxa of Membracoidea. He has also focused on the revision of the following leafhopper subfamilies: Nirvaninae, Typhlocybinae, and Neocoelidinae. Chris is currently employed with the Illinois Natural History Survey and in addition to research and mentoring graduate students, he co-organizes a systematics discussion seminar and guest lectures for their immature insects course. Online resources that Chris has available include a leafhopper page and a treehopper page. His lab page is also available here.

Dr. Gregory Evans: Greg received his Ph.D. in entomology from the University of Florida in 1993. A majority of his taxonomic research and numerous publications have focused on the taxonomy of whitefly, scale, aphid, and leafminer parasitoids. Primary taxonomy focus areas have been Encarsia and other aphelinids. In addition to his parasitoid expertise in these various groups, Greg has gained extensive experience in scale and whitefly taxonomy during his employment at (FDACS-DPI) (1998-2004). Greg recently (June 2004) began his employment with the USDA-APHIS-PPQ as an identifier for Coccoidea and Aleyrodidae samples from ports of entry.

Dr. Susan Halbert: Susan received her Ph.D. from the University of Illinois and her biological and taxonomic research has focused on aphids, particularly in association with plant virus transmission and pest complexes on agricultural crops. She currently works for the Florida Department of Agriculture, Division of Plant Industry and her taxonomic identification responsibilities include all of the Hemiptera and ‘Homoptera’ (excluding scales and whiteflies).

Dr. Gregory Hodges: Greg 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 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.

Dr. Douglass Miller: Dug received his M.S. (1965) and Ph.D. (1969) degrees from the University of California-Davis. His research has focused on the systematics of Coccoidea, with a particular emphasis on the Pseudococcidae and Eriococcidae. Dug has extensive identification experience in all families of Coccoidea, and his publications have also included Diaspididae, Margarodidae, Kermesidae, Micrococcidae, Coccidae, Putoidae, and Asterolecaniidae. Dug is currently employed by the USDA-ARS and his identification/collection responsibilities include the Coccoidea and Psylloidea. Dug also serves as the unit leader for the Sternorrhycha, Thysanoptera, Orthopteroids, Acari, and Molecular Systematics.

Dr. Gary Miller: Gary received his M.S. from the University of Tennessee (1982) and his Ph.D. from Auburn University (1991). His research has focused on the systematics of the Aphidoidea. Gary’s related entomological interests include the taxonomy of the Sternorrhyncha, scientific illustrations, cultural entomology, and the history of entomology. Gary is currently employed by the USDA-ARS systematic entomology laboratory and his identification/collection responsibilities include the Aphidoidea.  

Dr. Michael Williams: Mike 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.  Mike is also currently the chair of the Department of Entomology and Plant Pathology at Auburn University.

Dr. Stephen Wilson: Steve received his M.S. from Southwest Missouri State University (1975) and his Ph.D. from Southern Illinois University at Carbondale (1980). He worked at California State University at Chico from 1980-82. He began his employment at Central Missouri State University in 1982. Steve’s taxonomic research activities focus on Fulgoroidea, and he regularly mentors undergraduate and graduate students.

Training Site

This workshop will be held in a teaching laboratory in Gainesville, Florida at the University of Florida, Entomology-Nematology Building. The Museum of Entomology, Florida State Collection of Arthropods (FSCA) in Gainesville, Florida houses approximately 8 million arthropod specimens and is estimated to be the fifth largest collection of arthropods in North America.

Taxonomic specialists employed by the Florida Department of Agriculture, Division of Plant Industry (FDACS-DPI) curate the FSCA.  The availability of FSCA specimens will be an invaluable teaching resource for the workshop.  Participants are also encouraged to bring their unknown ‘Homoptera’ specimens to the workshop.  Depending upon the specimen, proper preservation in advance, including slide mounting if necessary, is recommended.
