Entomology

Modeling clay isn’t limited to art classrooms and sculpting studios. University of Georgia researchers developed a tool to track beneficial insects in turfgrass systems using clay models. Tracking these good predators can help develop eco-friendly pest management techniques for both home lawns and commercial sod growers.

In a recently published article in Entomologia Experimentalis et Applicata, UGA scientists determined that beneficial predator insects will interact with and leave distinct markings on clay models that resemble their prey, in this case the larvae of turfgrass pests. This study was led by entomology doctoral candidate Fawad Khan under the guidance of Assistant Professor Shimat Joseph in the College of Agricultural and Environmental Sciences on the UGA Griffin campus.

“We want to know who the predators are and what kind of impressions these predators will create on these clay models. Before we do anything in the field, we need to have a sense of what that looks like,” said Joseph, a turfgrass entomologist.

Though the clay model approach has been used in other disciplines to observe predator activity, Joseph and Khan found no previous use of the method in turfgrass research. This study developed clay models as a tool to aid in future research.

If you’ve ever wondered how to protect your home from termites, tune in to your local Georgia Public Broadcasting station this weekend when two University of Georgia professors will join forces to show viewers the proper steps to help keep their homes pest-free.

University of Georgia entomologist Dan Suiter, a professor on the UGA Griffin campus, and Nick Fuhrman, a professor in the College of Agricultural and Environmental Sciences (CAES) on the Athens campus — better known as “Ranger Nick” to viewers of the monthly Georgia Farm Monitor television show — will appear together on the July episode of the show with tips to stop termites.

We are pleased to announce that Dr. G. David Buntin, a dedicated member of the UGA faculty, has been named Interim Assistant Provost and Campus Director at the UGA Griffin campus, effective Nov. 1. He succeeds Dr. Lew Hunnicutt, who has been named the president of Nash Community College in Rocky Mount, North Carolina.  Dr. Hunnicutt has made several contributions to the UGA Griffin campus, including increasing graduate enrollment, elevating private support, and strengthening partnerships with the local community. I hope that you will join us in thanking him for his leadership at UGA-Griffin and congratulating him on his new leadership role.  Dr. Buntin is a professor of entomology in the College of Agricultural and Environmental Sciences, and his research and extension activities focus on integrated pest management. He has been an active member of several committees at both the college and university level, and we appreciate his willingness to lead UGA-Griffin during this transition period.

At 54, Becky Griffin was the oldest University of Georgia student on the Griffin campus to be awarded a degree this fall, but that fact only fueled her drive to succeed.

After putting her graduate studies on hold for 30 years, Griffin juggled a full-time job and put thousands of miles on her car to complete her master’s degree. The mother of two adult daughters, both of whom are UGA graduates, Griffin was encouraged to finish her degree by Kris Braman, a former UGA Griffin researcher who now heads the UGA Department of Entomology.

“Deciding to go back to school after 30 years was a huge decision. When I told Dr. Kris Braman why I didn’t have a master’s degree, she said, ‘Well, we need to fix that.’ She encouraged me to apply, helped me map out a plan and served as my major professor throughout this process. She was the first person on my team,” Griffin said.

The 2018 Young Scholars Program kicked off on Monday, June 4^th at the University of Georgia Griffin Campus with 20 students participating in the six-week internship program. High school students from the region were selected from a pool of 86 applicants to participate in YSP where they will spend the summer working alongside world-renowned research scientists at UGA Griffin.

This year we have eight returning young scholars: Austin Duncan, Tamara English, Mary Grace Johnson, Maddox Jordan, Sheilendria Rawls, Jolie Ryff, Martha Sikora and Sarah Smyly. Joining YSP for the first time are: William Anong, Samuel Cross, Joshua Duffey, Taaseen Khan, Yuheon Lee, Lauren Moyer, Meghan Rogers, Emily Shi, Melanie Wagner, Robert “Lee” Wall, Dean Watson and Caroline Zhang. The students will spend Monday through Thursday working with their mentors and on Fridays they will have exploratory site visits to various areas on campus and work-shops from insightful presenters about college/life skills.

Backyard squash growers may not agree on which variety is best, but they do agree on one thing – squash vine borers are the enemy.

The small larvae burrow through squash plant stems, wilting and eventually killing what appear to be lush, healthy plants. Since they are hidden inside the plant, most home gardeners have no idea the pests are there until the plants wither and die.

Squash vine borers overwinter in the soil, usually where squash or zucchini plants were planted the previous season. When the adults emerge from the soil, they lay eggs on the base of the stems of susceptible plants.

They love squash, too

The tiny destructive pests love to lay their eggs on summer squash, zucchini, winter squash and pumpkin plants but seldom attack cucumber and melons. After about a week, a pale larvae hatches and eats its way into the plant stems near soil-level. As water flow is cut off, the plant wilts and literally collapses.

There is no tried and true successful method to control the pest, but University of Georgia experts do offer tips for gardeners who choose to put up a fight.

To stay ahead of the pests, plant squash as early as possible so the plants are producing before the 6 to 8 summer weeks vine borers are active.

Georgia farmers are never surprised to see fall armyworms munching on their precious corn, sorghum and forage hay crops. They just hope for a low number of armyworms. This year’s population of the tiny destroyers, described as an “Armageddon-type outbreak” by University of Georgia entomologist David Buntin, is far from low.

A small grains pest expert with the UGA College of Agricultural and Environmental Sciences, Buntin spends his days tracking insects that can destroy Georgia row crops and working to determine the best methods of controlling them and establishing pesticide thresholds, or the number of insects that need to be present before a farmer should apply a pesticide.

“This year, the fall armyworms are way, way above the treatment threshold. They are here in much, much higher numbers,” he said. “As of the end of August, almost every pasture in central and north Georgia has been sprayed at least once and, for many of them, twice.”

Each year, the worms migrate up from the Caribbean and Florida. This year, they showed up early in corn and sorghum fields. Now they are in pastures earlier than normal.

Twenty-seven years after joining the faculty as a fledgling researcher, University of Georgia professor Kris Braman has been named the head of the university’s Department of Entomology.

“The entomology department at the University of Georgia is highly ranked and widely recognized for the strength and balance of its programs in core areas,” said Braman, whose appointment was effective July 1.

As the new department head, Braman sees the entomology program continuing to address current and emerging priorities in the discipline in a way that meets the needs of agricultural, urban and industry clientele.

A native of New York state, she earned a undergraduate degree in forestry at the State University of New York (SUNY) and a doctorate in entomology from the University of Kentucky.

“All SUNY forestry students were required to take entomology because insects are so important in managing forest health,” she said. “I was hooked for life before I was out of my teens!”

Braman joined the UGA College of Agricultural and Environmental Sciences faculty in 1989, working on the college’s campus in Griffin, Georgia. Since then she has conducted research on pests and beneficial insects of turfgrasses and ornamentals in urban settings.

A burgeoning interest in the benefits of delicious, local honey and increased concern for pollinator health has led more and more Americans to start keeping their own bees.

Bees can be raised successfully across the state of Georgia due to the state's long growing season and relatively mild winters. University of Georgia Cooperative Extension has the tools to help the novice beekeeper get started.

Putnam County Extension agent and beekeeping expert Keith Fielder will host a beekeeping basics workshop on Saturday, June 18, as part of the “Saturday at the Rock” educational series at Rock Eagle 4-H Center in Eatonton, Georgia. The workshop will include information on how to start and maintain a bee colony, as well as provide the chance to meet other novice and experienced beekeepers.

The beekeeping basics workshop is recommended for those 14 and older, but organizers will also host a child-friendly program for the junior beekeeper. Rock Eagle’s environmental education team will lead an exploration of the inner workings of a beehive and basic bee biology. Educators will share ways in which participants can attract honeybees to their yard, as well as discuss the many benefits bees can provide to the garden.

Both programs will run from 9:30–11:30 a.m. Doors will open at 9 a.m. Guests will convene in the center’s Natural History Museum preceding the program. Advanced registration for this program is required, and the cost is $5 per person.

Many food items, including fresh fruits and vegetables, would never make it to grocery store or farmers market shelves without the help of beneficial insects like honeybees and butterflies. The number of these pollinating insects in the U.S. is declining, and to help, Georgia agricultural experts developed a statewide plan to teach gardeners and landscapers how to care for their plants and protect these vulnerable insects that are vital to food production. “The issue is that we have broad-scale problems with our pollinators — both in numbers and in diversity,” said Kris Braman, an entomologist with the University of Georgia College of Agricultural and Environmental Sciences and a member of the team that created the “Protecting Georgia’s Pollinators” plan.

Pollination involves transferring pollen from the male parts of a flower to the female parts of the same, or a different, flower. This simple act of nature is essential to the production of many seed crops.

Insect pollinators contribute more than $24 billion to the U.S., according to a fact sheet released by the White House in June 2014. A 2014 economic impact study by UGA lists the annual value of pollination in Georgia at more than $360 million.
