Bermudagrass Stem Maggot

A new invasive fly, the Bermudagrass stem maggot, scientific name Atherigona reversura, was first discovered in 2010 damaging bermudagrass pasture and hay fields in Georgia. This was the first record of this species in North America and it has become a serious pest of Bermudagrass forage, hay and turf. Currently, it is spreading throughout much of the Southeast (now throughout FL, GA, SC). It was chosen as a target due to the strong concerns by producers, the lack of available information, and the potential to help producers immediately with a new invasive pest. This relatively new invasive species with potential for causing high losses of bermudagrass hay, requires development and demonstration of basic biology, ecology and behavior to help producers. Detection and monitoring methods such as scouting protocols, adult traps or other sampling methods (sweep nets, indicator plots), are being tested.

A monitoring network of select county agents and producers supervised by county agents have been set up for early detection and dissemination of early season warnings to producers via the website and social media.  This will enable infestations to be detected and suppressed before they reach higher populations that are more difficult to manage.
