Dr. Billy Crow was surprised on 18 March by Yellow Slime Mold growing in his office

ABOVE: Dr. Billy Crow was surprised on March18th by yellow slime mold (Physarum polycephalum) growing in his office! To the best of our knowledge this is a first for a faculty member in our department and is surely a sign of his scientific prowess (or that he needs to clean his office).

Yellow slime mold is a multinucleate, single-celled, amoeboid organism that feeds on decomposing plant matter. It forms macroscopic colonies of plasmodium such as in Dr. Crow's office for purposes of reproduction. This is an amazing organism, whose colonies have been shown the ability to solve mazes.

Congratulations are in order to two post doctoral associates working in the Hahn Lab.

  • Dr. Giancarlo Lopez-Martinez has been offered a position as a tenure track assistant professor in the Department of Biology at New Mexico State University in Las Cruces.
  • Dr. Caroline Williams has been offered a position as a tenure track assistant professor in the Department of Integrative Biology at the University of California in Berkley. 

Dr. James P. Cuda was a guest instructor for Aquatic Weed Control (AGR6932), a graduate level course in the Agronomy Department. Cuda gave a lecture on biological control of aquatic weeds on March 18th and conducted a field laboratory exercise at the Center for Aquatic and Invasive Plants on March 20th.

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. Lyle Buss is the Insect ID Lab manager.

Tiki pest

ABOVE: An interesting sample that Lyle received in March was a tiki hut pest from Naples. It is a noctuid moth named Simplicia cornicalis. The caterpillars feed on dead plant tissue, especially cut palm leaves that are used for thatch roofs in south Florida.

These caterpillars can do heavy aesthetic damage to the leaves, plus folks don’t appreciate the fecal pellets raining down on their food and drink. Lyle had a couple of similar cases from Hillsborough County last fall. This species is native to Asia, and was first found in Florida in 2006. Please let Lyle know if you see this insect!

Think it might be a nematode problem? The Nematode Assay Laboratory serves Florida and other states by providing nematode assay and expert advice regarding nematode management. For more information on the Nematode Assay Laboratory please contact the Lab Manager Dr. Tesfa Mengistu.

Dr. Marjorie Hoy is attending the Rose Rosette Disease Summit in Newark, Delaware, April 14th to 16th where she presents a talk on "Biological Control of Eriophyid Mites, Vectors of Rose Rosette Disease." The goal of the conference is to develop a comprehensive strategic research and education plan. The conference was organized by Star Roses and Plants and sponsored by All America Rose Selections and the Garden Rose Council.

Dr. Verena Lietze represented the Hydrilla IPM RAMP team at the "Sustaining Economies and Natural Resources in a Changing World: Key Role of Land Grant Universities" symposium held at the Reitz Union on April 2-3.  The team’s poster was entitled "Hydrilla Integrated Pest Management Risk Avoidance and Mitigation Project" and showcased the project's mission as well as recent research results.

Dr. James P. Cuda was an invited speaker for the FWC-IFAS Research Review for Invasive Plants in Florida held at the Plant Science Research and Education Unit, Citra, FL, March 12th and 13th. Cuda was a presenter and/or co-author on three presentations dealing with biological control of Brazilian peppertree and cogongrass.

Celebrated insect photographer Dr. Alexander Wild presented two seminars at UF on April 4th (host: Dr. Andrea Lucky). His research talk in the departmental seminar series, Traveling across the taxonomic divide: Tales from tropical wasps, offered a glimpse into the vast diversity of insect species that remain to be formally described. The talk was standing-room only, with approximately 70 people in the audience.

Alex Wild at the Harn

One of the goals of this arts-sciences collaboration was to reach a diverse and inter-disciplinary audience; success was evident by the diversity of attendees, which included scientists, artists, insect enthusiasts, photography buffs, as well as students and retirees. In this presentation, the speaker offered practical and inspiring suggestions for improving macro-photographic technique. In addition to treating the audience to his stunning images of ants and other insects, he also emphasized that photography is one avenue that can lead to conservation, and he argued that "If you take better photographs of nature, you'll like nature more." Alex Wild’s talk at the Harn was followed by an extended question-and-answer session and a reception sponsored by the Entomology & Nematology Department.

Getting Social

 

We have several social media sites for the Entomology & Nematology Department. To make them easily searchable, all three (YouTube, Facebook and Twitter) have the same page name, UFEntomology. Please share these links with past students or colleagues who may have an interest in departmental activities.

The DPM program would like to invite our newsletter readers to like their Facebook page to keep up with DPM events and developments. Be sure and "Like" the DPM Facebook page.

Honey Bee Research and Extension Laboratory wants you to follow them on twitter to find out about upcoming events and interesting stories about honey bees @UFHoneybeelab.

The Entomology Club was able to interact with 71 schools from 36 counties at the Junior Science, Engineering and Humanities Symposium (January 27th to 29th at the Reitz Union). We hope our participation will encourage these students to consider entomology as a major when they come to college. They said our hands-on approach was appreciated and we had one of the most-visited booths. 

Dr. James P. Cuda was invited speaker for in an invasive species workshop for personnel affiliated with the Wekiwa Springs State Park located in Apopka on March 29th. Cuda gave a presentation on management of invasive insects and weeds with biological control.

From the Outreach Coordinator

Outreach events for the last month included two visits to the department for lab tours. Thank you Dr. Koehler, Dr. Crow and Dr. Hahn for participating in those. We visited Williston Central Christian Academy, Norton Elementary, and Belleview Santos Elementary. 

Because FCAT testing occurs in April, we anticipate things being a bit slower, but then there is May. We already have many requests for outreaches for that month, and since they are after finals, we would really appreciate some assistance. We need volunteeres for the afternoons of May 7th, May 9th, May 10th, May 13th, May 15th, and May 16th. If you are interested in participating, please contact Stephanie Stocks.

The live critters are always a hit with children and adults alike. The critters are available for you to check out should you be leading an outreach event. We have doubles of our most popular critters, as well as various native insect species depending on the time of year. We have large wood and Plexiglas cages for viewing our native orb weaving spiders. There is one travel cage and one larger static cage. Please be sure to contact us and review the protocol on transporting and handling the critters if you are not already familiar with it. If you lead an outreach, be sure to fill out a documentation form so your event can be included in the newsletter and we can log all outreach events.

If you would like to schedule an event or have any outreach questions, go to the Outreach pages on our Bug Club Website and contact us. I look forward to working with all of you over the next four years.
