Monday, October 31, 2022

Since first making their appearance in Georgia in 2014, Joro spiders have steadily expanded their range in Georgia, and now — just in time for Halloween — the spooky-looking species has reached the University of Georgia Research and Education Garden on the UGA Griffin campus.

Native to Japan and China, Joro spiders are believed to have made the trek overseas by hitching a ride in a shipping container. The striking arachnid spotted at UGA-Griffin is thought to be the first documented sighting of the species in Spalding County. So far, sightings have been limited to the northern region of the state. Spalding County is located about 40 miles north of the Georgia fall line, which separates the Piedmont region of the state from the Coastal Plain.

Monday, August 30, 2021

Thousands of Georgians came together on August 20 and 21 to count pollinator insects in their local gardens for the third annual Great Georgia Pollinator Census

Coordinated by University of Georgia Cooperative Extension, the Great Georgia Pollinator Census (GGPC) is designed to track the overall health of Georgia’s pollinators. Georgia citizens of all ages and backgrounds are encouraged to participate in the count each year, and the census has attracted participation from businesses, school groups and garden groups, as well as families and individuals around the state.  

Giant invasive bees could threaten native pollinators

University of Georgia entomologists are seeking citizen help to document the presence of the sculptured resin bee — also known as the giant resin bee — an invasive bee that could threaten the native carpenter bee population.

The sculptured resin bee is native to Japan and China and was first found in the U.S. in North Carolina in 1994. While they are not aggressive to people, these bees have the potential to create problems for native carpenter bees by taking over their nests, where they then lay their own eggs. Sculptured resin bees take advantage of the cavities created in wood by carpenter bees because they do not have the mandible strength to bore into the wood on their own.

Dan Suiter, a professor in the Department of Entomology on the UGA Griffin campus, added that although he doesn't see resin bees frequently, they are known to be a good pollinator of some plant species.

“We don’t see this bee very often,” said Suiter, noting that he is occasionally sent a sample of a resin bee to identify. “But we know that it’s invasive and uses kudzu as a food source.”

Insecticide residue in the soil harms wild bees

New research funded by the Southern Sustainable Agriculture Research and Education program and conducted at the University of Georgia shows that imidacloprid residue harms wild bees.

In a first-of-its-kind study, Christine Fortuin, now a postdoctorate researcher at UGA, developed a more accurate understanding of the lethal and sublethal effects of neonicotinoid exposure on blue orchard mason bees by studying multiple pathways of imidacloprid exposure.

“Imidacloprid is a neonicotinoid, which is a group of pesticides that are highly toxic to bees. It has several common uses but my research was focused on the soil-drench application method. This is when it is applied directly to the soil and soaked up through the roots of the tree to prevent beetles and other pests,” explained Fortuin.

She worked with Kamal Gandhi, a UGA professor of forest entomology, to conduct the research through Southern SARE’s Graduate Student Grant program.

Blue orchard mason bees are one of the few bees native to North America that can be a managed pollinator for orchard crops like apples, cherries and blueberries. Mason bees are members of the Osmia bee family and are considered a wild and solitary species. They have no queens or worker bees and while this dark, metallic blue pollinator may be similar in size to a honey bee, both its lifecycle and interactions with the environment are very different.

Your lawn could help save the bees

Over the past few decades, pollinators have been in decline worldwide, which is concerning because 70% of crops used for human food depend on pollinators. Turfgrasses – used for most residential lawns – often take some of the blame for pollinator decline as they are known to be wind-pollinated and were thought not to serve as a pollinator food source, until now.

University of Georgia and U.S. Department of Agriculture researchers identified bees that were collecting pollen from the flowers of a turfgrass called centipedegrass. The researchers have been looking for ways to reverse the decline of pollinator populations by examining centipedegrass as a food source for pollinators, with hopes of normalizing low-maintenance, bee-friendly lawns. Their findings have been published in the Journal of Entomological Science and Insects.

The study was led by College of Agricultural and Environmental Sciences faculty Shimat Joseph and David Jespersen on the UGA Griffin campus alongside USDA researcher Karen Harris-Shultz in Tifton.

Clay models track the activity of beneficial insects in turfgrass

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.

UGA-Griffin student returns to college after 30-year break

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.
