Paul and Lois, we appreciate your 75 years of combined service!

Paul Ruppert retires this month after nearly 40 years of employment with the department in Gainesville. Paul’s relationship actually extends back a bit further, as he worked with Citrus County Cooperative Extension, and then the Vegetable Crops Department, before moving to Entomology & Nematology. Paul devoted most of his career to Extension-related activities, and was affiliated with faculty such as Dr. Freddie Johnson (veg and field crop entomology), Dr. Don Short (turf and ornamental entomology), Dr. Susan Webb (vegetable entomology), and Dr. Eileen Buss (turf and ornamental entomology).

For several years Paul coordinated the department’s diagnostic activities in support of county staff and the general public. Along the way he also found time to become a certified arborist and certified to teach in youth agricultural programs. More recently he assumed department-wide support activities, thereby coordinating renovation, maintenance and repair of Steinmetz Hall, its support structures, and landscaping. He will be missed by the department, but welcomed at home by his wife Kathleen, who preceded him in retirement and who has been working on a long list of projects for him to do so he doesn’t get bored in retirement. 

retirees

ABOVE: Our August retirees Paul Ruppert (left) and Lois Wood (right) have a combined 75 years of service to our department. Their contributions cannot be expressed in a few sentences, but we have given you a snapshot here of their time with us.

On August 31, 2017, Lois Wood, will be retiring after 35 years of service with our department. Lois received her M.S. with Walter Tschinkel at Florida State University in 1979 and then spent three years conducting studies for the state of Florida on salt marsh-inhabiting sparrows and several endangered species. Lois joined our department and began working with Dr. Jerry Stimac’s laboratory in September 1982 where she assisted with his insect pathology program that focused on Beauveria bassiana. While working with Jerry, Lois had the enviable opportunity to work in Brazil where she spent 6+ months on a fire ant project.

From 2003 until early 2005, Lois worked with Dr. Eileen Buss in the landscape entomology program. Thereafter, Lois joined the veterinary entomology program with Dr. Phil Kaufman where she coordinated studies on an array of fly and tick pests, dung beetles, and insecticide evaluations as well as tracking the myriad of regulatory requirements, graduate student needs and supervision of the program staff. Lois’ daily presence will be missed, but we know she looks forward to enjoying her free time to engage in volunteer efforts and spend more time with her horse, Shoshone, and less time on Archer Rd at 7:45 am. If you have a chance, stop by room 3237 and wish her well before the end of the month. Thank you Lois for your exceptional commitment to UF and the department!

Dr. Peter DiGennaro has been accepted as a faculty member of the University of Florida Genetics Institute.

Dr. Peter DiGennaro and Dr. Jennifer Gillett-Kaufman served as UF/CALS Florida Youth Institute expert panelists to help choose the Florida representatives to the Global Youth Institute sponsored by the Word Food Prize Organization.

Dr. Mei-Ying Lin, from the Chinese Academy of Sciences has just started a 12 month sabbatical with the Branham Lab where she will be continuing her research on the systematics and taxonomy of the beetle family Cerambycidae.  Stop by and introduce yourself to Dr. Lin!

Martini award

ABOVE: Dr. Xavier Martini (North Florida Research and Education Center) was awarded the 2017 Annual Achievement Award for Research by the Florida Entomological Society at the last meeting of the society in Puerto Rico on July 19th.

Ms. Adriana Mitchell, a former biological researcher for Dr. Emma N.I. Weeks and Dr. James P. Cuda, won the non-student poster competition at the 57th Annual Meeting of the Aquatic Plant Management Society held at Daytona Beach, 16-19 July. Adriana received $100 for her poster titled “Impact of food deprivation on hydrilla tip-mining midge survival and subsequent development.” The poster was co-authored by Alissa Berro, Dr. Cuda, and Dr. Weeks. Adriana has since moved on from the laboratory to a position as an executive secretary for Senator Keith Perry.

Need to name that bug? A host of experts are available to help Floridians identify any insect or related arthropod. If a mystery creature has six or more legs, the UF Insect ID Lab is the place to call.

caterpilliar

ABOVE: Several people in the Gainesville area have mentioned seeing variable oakleaf caterpillars feeding in their oak trees lately. The caterpillars feed high up in the canopy, so they often are not noticed until frass is raining down, defoliation is significant, or caterpillars are leaving the trees in order to pupate in the soil. As you would expect from their name, the caterpillars can be found with several different color patterns, a couple of which are shown here  If you see large populations of these caterpillars or other insects, please let Lyle know. Knowing where outbreaks are occurring helps him handle public inquiries, and often provides nice photo opportunities!
