Faculty News

Dr. Lukasz Stelinski joined the faculty of the Citrus Research and Education Center at Lake Alfred, where he begins his new appointment as assistant professor of citrus IPM. Lukasz's appointment is 80% research and 20% extension. In the immediate future, he will develop a research program focusing on integrated management of citrus leafminer, Diaprepes root weevil, and Asian citrus psyllid. His interests include applications of chemical ecology for pest control and insect behavior. Lukasz completed his M.S. and Ph.D. degrees in entomology in Michigan, focusing on use of behavior-modifying chemicals for insect control in small fruit and tree fruit systems and a post-doc focusing on mating disruption of lepidopteran pests. His wife Kirsten is completing her Ph.D. in Michigan and expects to join him in six to eight months. Detailed information about Lukasz's research interests and recent work is available at http://www.crec.ifas.ufl.edu/academics/faculty/stelinski/stelinski_lukasz.htm.

Dr. Freddie Johnson retired for the second time, this time as director of a UF/IFAS Extension District. At a recent faculty meeting, he was elected to Emeritus Professor status.

Two of our faculty received awards at the ESA-Southeast Branch (SEB) meeting in Tennessee, 4-7 March. Dr. Rudi Scheffrahn received the SEB 2007 Recognition Award in Urban Entomology, and Dr. Faith Oi received the SEB 2007 Distinguished Achievement Award in Extension. Both are nominees for the ESA 2007 awards in these categories.

Dr. James P. Cuda was selected to participate in the 2007 Grantsmanship Workshop co-sponsored by the Office of the Dean for Research and the California based Grant Writers' Seminars and Workshops Company.

Dr. James Cuda was selected to serve as the department's liaison for IFAS International Programs. Cuda will serve as the initial point of contact for inquiries and requests from that office, and will be an advocate for international activities within our department.

Staff News

Dr. Khuong Nguyen, Senior Biological Scientist, received a 2007 UF/IFAS Superior Accomplishment Award in the Scientific/Technical category for his work. While not the entire basis for the award, Dr. Nguyen has earned international recognition for his work in identifying new species of nematodes in the U.S. and around the world.

Student News

At the recent SEB meeting, two of our graduate students took first and second place in the Ph.D. Student Paper Competition.

The First Place winner is John Herbert with "Effect of crape myrtle Lagerstoemia spp. parentage on its suitability as a host for the crapemyrtle aphid Sarucallis kahawaluokalani." Dr. Russ Mizell is co-author.

Second Place winner is Karla Addesso with "Response of the pepper weevil, Anthonomus eugenii Cano, to volatiles from host plants." Drs. Heather McAuslane and Hans Alborn are co-authors.

Dr. Rudi Scheffrahn reports that Teresa Ferriera is a new graduate student in his lab at the Ft. Lauderdale REC campus. Teresa is studying colonization behavior, preventative treatments, and genetics of the West Indian drywood termite, Cryptotermes brevis. Her four-year fellowship is funded by the Portuguese Science Foundation in response to a serious outbreak of this pest on Terceira and San Miguel Islands, Azores. Many of the infested structures are of great historic significance as well as serving as homes and businesses for the Azorean people.

Dr. Carl Barfield, Undergraduate Coordinator, reported at the last faculty meeting that we now have 31 undergraduate majors, with an average GPA of 3.4.

Alumni News

Gino Nearns, previously with Dr. Marc Branham's Lab, is currently a doctoral student at the University of New Mexico. However, he is the 2007 recipient of the UF/IFAS Award of Excellence for Graduate Research - M.S. level, for his research on "Revision and phylogeny of the tribe Curiini LeConte (Coleoptera: Cerambycidae: Cerambycinae)." Gino will receive a plaque and check for $600.00 at the CALS 7th Annual Graduate Research Symposium.

Gino Nearns also received the Kirby Hays Memorial Award for Outstanding Masters Student at the SEB meeting.

Meetings and Presentations

Dr. Billy Crow was an invited speaker at the Golf Course Superintendents Association of America Conference and Show in Anahiem, CA, in February. He presented research results on timing of nematicide applications to a mixed audience of golf course superintendents and turfgrass researchers. While in CA, Dr. Crow visited the campus of UC-Riverside where he spent the day exchanging notes with California extension nematologists Ole Becker and Antoon Ploeg.

Dr. Billy Crow was an invited speaker at the Carolinas Golf Course Superintendents Conference and Show in November. He taught a four-hour seminar on nematode management to golf course superintendents.

Dr. Marc Branham and graduate student Seth Bybee recently returned from a two week trip to Moscow, Russia. They were invited to photo-document the more than 300 million year evolutionary history of fossil Odonata at the world's largest fossil collection, the Paleontological Institute of the Russian Academy of Sciences. The trip was a success and resulted in more than 20 GB of images representing nearly all of their fossil dragonfly holotypes. While in Moscow, they noted the weather in Gainesville was in the 70s, while the temperature in Moscow was around -30 F, a 100 degree difference.

A Featured Creatures photograph of an Indianmeal worm larva, taken by Lyle Buss, was used to illustrate a National Public Radio "Science Friday" article on how viruses change how effectively they transmit themselves depending on host availability.
