The Joro spider is native to East Asia and was first detected in Georgia in 2014. It is found in Georgia, North Carolina, South Carolina, and Tennessee, and is spreading to adjacent regions. It has one generation per year in its native range.
Adult females become sexually mature in September and early October. The female’s body is bright yellow with broad, horizontal bluish-green bands on the top side of the abdomen, and large red markings on the bottom side of the abdomen. She also has long, black legs with yellow-orange bands or—rarely—all black legs. Adult males mature by late August. The male’s cephalothorax is light brown with two dark brown long bands on both sides. His abdomen is elongate-oval with a greenish-brown topside that has two yellowish long stripes on both sides of the dark brown middle line.
Are Joros disrupting the ecosystem and displacing native species? This is a big question that a newly formed team of scientists is working on. However, we also need your help. The first thing we need to know is where Joro spiders are. Use the Joro Watch website (https://jorowatch.org) or the EDDMapS app to submit observations from parks, forests, and even your own yard. Fill out the report form and, if you can, count how many Joro spiders you see and upload pictures.

In commercial poultry houses, bird density and distribution in drinking, feeding, and
resting zones are critical factors for evaluating flock productivity, bird health, and well-being. Proper distribution of chickens in the house greatly influences animal well-being and house environmental management. Currently, routine daily inspection of broiler flock distribution in commercial grow-out houses is done manually, which is labor-intensive and time-consuming. UGA poultry science researchers currently are developing an automated imaging system for monitoring floor distribution of chickens.Ongoing studies are focusing on detection of individual chickens with different gait scores in the research facility. It’s challenging to track individual birds with early health or welfare concerns using a computer vison-based method, but it is necessary and critical for producers to identify birds with well-being concerns and address those issues quickly.

Experimental power determinations are very important to agriculture and other applied sciences. It is necessary to be able to detect
small differences when human and animal health or production profitability are in question. Yet textbooks on biostatistics for
agriculturalists generally barely introduce the subject of how to design an experiment to detect some important difference between
treatments. To come to meaningful conclusions, researchers need to know how to plan both plan and conduct experiments. Entirely different
questions may be asked of an experiment depending on who is to interpret the results. Developers may be most interested in showing
that their new product gives responses not statistically significantly different from some standard. Potential consumers, on the other
hand, should be more interested in demonstrating that expected responses from a new product are equal to the standard|

Vegetables comprise an economically important segment of Georgia’s agricultural production, so there is a need for vegetable breeders to have comprehensive, crop-specific data on grower priorities, varietal performance, and production constraints.
UGA’s vegetable breeding program performed a needs assessment survey to assess growers’ preferences, the results of which are presented in this resource. This data will be used to inform the development of regionally adapted high-performing vegetable varieties.

This resource describes whiteflies and the damages they cause in cucurbit crops, and offers recommendations for cucurbit crop varieties for fall season production in southern Georgia that are resistant or tolerant to silverleaf disorder and whitefly-transmitted viruses.

Satsumas are one of the most cold-hardy of all citrus and very adaptable to Georgia, but very little is known about growing citrus in Georgia. Commercial growers and residents often ask which early-maturing varieties are best to grow, so we evaluated juice from 12 early-maturing satsuma varieties. The varieties with the highest Brix content and best peel color are listed in this resource.
