Gnats (Black Flies) 
In Tennessee’s warm months, gnats are a nuisance to people and animals. UT researchers are working to reduce the population by eliminating them before they’ve hatched from rivers and streams.

(3 mentions)

Bee Research 
Researchers at the UT Institute of Agriculture are exploring reasons behind the decline of the honeybee population, including how agricutural pesticides might affect these beneficial insects.

(2 mentions)

Insects are among the greatest threats to agriculture. Tennessee farmers have seen some pests disappear, but in the process, new ones emerged, and they are attacking fields.

(2 mentions)

Honeybees are dying nationwide due to a disease that is wiping out colonies. UTIA researchers are working to save the bee population in our state.

Ag Year Preview 
Spring is almost here, and it’s just about time for Tennessee farmers to plant their 2012 crops. All indications are - things are looking good for producers, following what was a good year in 2011.

(1 mention)

Beetle Tents 
Hemlock trees in the Smoky Mountains are threatened by a tiny, deadly pest. Researchers with UT AgResearch are using a predatory beetle to feast on these harmful insects.

(1 mention)

Livestock Research 
It's a problem for Tennessee farmers who produce our top commodity -- beef cattle. Insects such as flies cause serious health problems for their animals, and reduce product quality for consumers.

(1 mention)

Nursery Industry 
Tennessee is a top producer of ornamental plants. The nursery industry here is concentrated in a very specific part of our state, known for a mild climate and growing beautiful trees and shrubs.

(1 mention)

Art and Insects in the Gardens 
The UT Gardens in Knoxville offer a combination of beautiful plant life, agricultural research and artwork. The gardens have several displays this sumer that give visitors an eye-popping experience.

(1 mention)

Bed Bugs 
Good night. Sleep tight. And don't let the bed bugs bite. Once a harmless nursery rhyme, now it's anything but a laughing matter. Like much of the US, Tennessee has bed bugs.
