Like many other mosquito species, the larvae of Culex pipiens, commonly referred to as the common house mosquito, require certain vitamins to grow. These nutrients are extremely unstable in aquatic environments, and UGA researchers have found that gut microbes have to produce these components continuously in order for organisms like mosquito larvae to develop.

Mosquito Microbiota
To most people, mosquitoes are a nuisance. To University of Georgia entomologist Michael Strand, learning about their development processes could lead to new approaches in mosquito control.
The UGA cotton research team identified 24 Georgia counties where the presence of cotton leafroll dwarf virus (CLRDV) has been confirmed from commercial fields and UGA research farms during 2018-2019. CAES News
Cotton Leaf Roll Dwarf Virus
While aphids aren’t a direct threat to cotton plants, they can carry a persistent virus that is difficult to control and can cause significant losses in one of Georgia’s most important crops.
Common seasonal pests like (clockwise from top right) fire ants, houseflies, brown marmorated stink bugs and mosquitos (shown in standing water as larvae) can be controlled with simple tips from UGA Cooperative Extension. CAES News
Summer Pests
As a University of Georgia Cooperative Extension agent, I see a lot of insects. People leave jars of them on my desk, send me photos or call me out to their gardens to identify them and give control recommendations.
Blubaugh Lab manager Katherine Hagan and master’s student Allison Stawara scout squash for various beneficial and pest insects as part of a living mulch study at the Durham Horticulture Research Farm in Watkinsville, Georgia. CAES News
Organic Pest Control
The hot, humid climate in the Southeast lends itself to nearly year-round insect, weed and disease pressure, and growing is especially tough if you’re an organic farmer.

Salmonella in cattle
Growing resistance to our go-to antibiotics is one of the biggest threats the world faces. As common bacteria like strep and salmonella become resistant to medications, what used to be easily treatable infections can now pose difficult medical challenges.
When using pesticides, remember that the safe and legal use of pesticides requires that the entire label be followed exactly. Contact your local Extension agent if you're unsure about a product. CAES News

As we head into summer, we start to see problems with weeds, diseases and insects in the landscape and around vegetable gardens. Some of these pest problems can be solved without the use of chemicals, but if the pest population reaches damaging levels, using pesticides may be warranted. Remember that using pesticides is safe and legal but requires reading and following label directions in their entirety.

Large Patch
As warm-season turfgrasses continue to green up, diseases are rearing their ugly heads. The main culprit this time of year is a fungus, Rhizoctonia solani, that causes large patch disease in lawns. Large patch can infect all warm-season turfgrasses, but centipede, St. Augustine, and zoysia are particularly susceptible.
Argentine black and white tegus, the largest of all tegus, can reach 4 feet long and weigh 10 pounds or more. CAES News
Invasive Tegus
University of Georgia Cooperative Extension is assisting the Georgia Department of Natural Resources (GDNR) in the effort to find and remove tegus from the wild in southeast Georgia, and the public’s help remains critical to keeping these big, South American lizards from getting a toehold in the state.

Best of Both Worlds
The wild relatives of modern peanut plants have the ability to withstand disease in ways that modern peanut plants can’t. The genetic diversity of these wild relatives means that they can shrug off the diseases that kill farmers’ peanut crops, but they also produce tiny nuts that are difficult to harvest because they burrow deep in the soil.
