Millions of Sterile Flies Released in Screwworm Eradication Effort

Dr. Phillip Kaufman discussed sterile fly releases, release zone adjustments and steps producers can take to protect livestock.

COLLEGE STATION, Texas (RFD News) — Efforts to eradicate New World screwworm remain a focus for the livestock industry as Texas agriculture continues working with state and federal agencies to respond to recent detections.

Dr. Phillip Kaufman from Texas A&M University joined us on Wednesday’s Market Day Report to discuss the latest developments.

In his conversation with RFD News, Kaufman discussed USDA’s use of sterile flies and adjustments to release zones as detections change. He said he believes between four million and eight million sterile flies are currently being dispersed in affected counties as part of the eradication effort.

Kaufman explained that the sterile insect technique works by releasing sterile male flies to mate with wild females. Because female screwworm flies typically mate only once, any eggs produced after mating with a sterile male will not hatch, helping reduce the population over time.

Kaufman said affected areas have been placed under investigation zones with animal movement restrictions designed to keep the fly contained. He added that officials hope other states and countries continue viewing the rest of Texas as safe for livestock imports.

He encouraged producers to regularly inspect animals and establish a veterinarian-client relationship.

“The best thing producers can do is put eyes on their animals. If you see anything suspicious and you’re able to catch that animal, catch it. Look at it. If you see an open wound, we’re asking you to treat that wound and bring in your veterinarian.”

Kaufman said producers should establish a veterinarian-client relationship, noting that many of the most effective screwworm treatments require veterinary authorization.

He added that livestock producers have access to far better treatment options than were available during the 1960s screwworm outbreak.
