Refugee Disease Risk
The destruction caused by war is evident both in its toll to human life and its impact on infrastructure. Those who are lucky enough to escape violence face many challenges, from finding a safe place to live to securing employment, but another threat could further jeopardize their ability to survive — an increased risk of illness.

Solitary Oak Leafminer
“What’s wrong with the leaves of my oak tree?

Whether white, red or chestnut oaks, the question has been the same.

Fire ant mounds seen on the surface of our lawns and fields are just a small portion of the ant colony where soil has been excavated to the surface. These colonies are unsightly and occasionally dangerous. CAES News
Fire Ant Management
There are many things you come to expect living in the Southern U.S. You can count on sweetened ice tea being available at every restaurant, there will always be festivals named after fruits and vegetables, and the weather after Easter will never make any sense. You can also count on fire ant mounds appearing in late spring.

Buttercup Control
Spring has undoubtedly arrived in Georgia. Local pastures and lawns remind me of the lyrics from “America the Beautiful,” “Oh beautiful, for spacious skies, for amber waves of grain.” Except that almost every call this week has been about amber waves of buttercup, something that neither livestock nor humans like to eat.
Adaptable and hungry, Argentine black and white tegus pose a significant threat to native wildlife, from gopher tortoises to ground-nesting birds. The public should report tegus seen in the wild, alive or dead. (Photo by Dustin Smith/Georgia DNR) CAES News
Report Tegus
Warming temperatures will have tegus on the move in southeast Georgia. Reporting sightings of tegus, alive or dead, is needed to keep the big, South American lizards from gaining a foothold in the state, according to the Georgia Department of Natural Resources.

Mosquito Metamorphosis
Jena Johnson, a lab manager in the Department of Entomology in UGA’s College of Agricultural and Environmental Sciences, captures what she observes working with mosquitoes and other insects in the lab of entomology professor Michael Strand. She finds scientific and artistic meaning in her photos, which offer a glimpse at both intriguing behavioral phenomena and unexpected natural beauty.

Plum Curculio
With the onset of warmer, longer days, an array of pink blooms from peach, cherry and plum trees break forth — the first signs of spring. And while most of us enjoy this seasonal shift, fruit tree growers prepare their orchards for the relentless, annual migration of insect pests.

Fungicides Driving Resistance
New research from the University of Georgia has shown, for the first time, that compounds used to fight fungal diseases in plants are causing resistance to antifungal medications used to treat people.
