A supergene is a collection of neighboring genes located on a chromosome that are inherited together due to close genetic linkage. Studying these unique genes is important to understanding the potential causes for differences among the social structure of fire ants, specifically for controlling the species and building upon the existing knowledge base.

A supergene is a collection of neighboring genes located on a chromosome that are inherited together due to close genetic linkage. Studying these unique genes is important to understanding the potential causes for differences among the social structure of fire ants, specifically for controlling the species and building upon the existing knowledge base.
Fire ant supergene
A unique study conducted by University of Georgia entomologists led to the discovery of a distinctive supergene in fire ant colonies that determines whether young queen ants will leave their birth colony to start their own new colony or if they will join one with multiple queens. Researchers also found that ants were more aggressive toward queens who don’t possess the supergene, causing colony workers to kill them. This critical finding opens the door to new pest control methods that may be more efficient in eradicating problematic fire ant colonies.

Nematode Research
While weeds and plant parasites are a concern for all agricultural producers, organic producers are doubly challenged to combat these problems without chemical solutions. Through a grant from the U.S. Department of Agriculture, a University of Georgia researcher is working to discover and integrate biological products and cover crops to control nematodes and weeds in organic vegetable production.

Milkweed Pests
With the fall migration underway for monarch butterflies through November, gardeners should soon start seeing the colorful creatures on their travels south. It's also time to be on the lookout for pests of common milkweed (Ascelpias tuberosa), the most popular milkweed plant grown in Georgia butterfly gardens.

Cool Weather Pests
As the weather cools across the state, several fall insects will begin to take center stage around Georgia homes. Be on the lookout for these nuisance pests and make preparations to deter them from entering your home for the winter.
