AgriLife leaders highlight past experience to protect Texas livestock and wildlife

Texas A&M AgriLife leaders are sharing lessons learned from Florida’s 2016 New World screwworm outbreak to help protect Texas wildlife and livestock.  

Dr. Roel Lopez, director of Texas A&M Natural Resources Institute, and Dr. Phillip Kaufman, head of the Department of Entomology, were key figures during Florida’s crisis. 

The outbreak in Florida was the first U.S. case in over 30 years and heavily impacted the endangered Key deer population. Lopez’s team monitored deer health, studied the outbreak’s effects, and helped with recovery plans. 

Kaufman, who worked in Florida at the time, played a vital role in educating the public and supporting local extension agents with updated information. Both experts emphasize the importance of being alert and reporting unusual animal cases. 

Florida’s response was successful due to a rapid, joint effort by various agencies. Measures included releasing sterile male flies, treating affected animals, and monitoring. Despite not reaching mainland Florida, the outbreak killed around 15% of the Key deer population. 

“The biggest challenge with wildlife is monitoring and early detection,” said Lopez. “With this in mind, investigation of suspicious mortalities or the use of game cameras can serve as an invaluable tool for landowners to monitor wildlife health and document any signs of infection.” 

Monitoring wildlife, using cameras, and investigating sudden deaths can help identify infections early. Kaufman suggests that wildlife operations should have biosafety and herd management plans, like livestock producers. Tracking high-value animals is also recommended. 

With reports of screwworms moving north from Mexico, Texas has a chance to prepare and act early. As Lopez says, “If you see something, say something.”

Spring 2026 weather outlook for Wisconsin; What an early-arriving El Niño could mean

Video: Spring 2026 weather outlook for Wisconsin; What an early-arriving El Niño could mean

Northeast Wisconsin is a small corner of the world, but our weather is still affected by what happens across the globe.

That includes in the equatorial Pacific, where changes between El Niño and La Niña play a role in the weather here -- and boy, have there been some abrupt changes as of late.

El Niño and La Niña are the two phases of what is collectively known as the El Niño Southern Oscillation, or ENSO for short. These are the swings back and forth from unusually warm to unusually cold sea surface temperatures in the Pacific Ocean along the equator.

Since this past September, we have been in a weak La Niña, which means water temperatures near the Eastern Pacific equator have been cooler than usual. That's where we're at right now.

Even last fall, the long-term outlook suggested a return to neutral conditions by spring and potentially El Niño conditions by summer.

But there are some signs this may be happening faster than usual, which could accelerate the onset of El Niño.

Over the last few weeks, unusually strong bursts of westerly winds farther west in the Pacific -- where sea surface temperatures are warmer than average -- have been observed. There is a chance that this could accelerate the warming of those eastern Pacific waters and potentially push us into El Niño sooner than usual.

If we do enter El Nino by spring -- which we'll define as the period of March, April and May -- there are some long-term correlations with our weather here in Northeast Wisconsin.

Looking at a map of anomalously warm weather, most of the upper Great Lakes doesn't show a strong correlation, but in general, the northern tiers of the United States do tend to lean to that direction.

The stronger correlation is with precipitation. El Niño conditions in spring have historically come with a higher risk of very dry weather over that time frame, so this will definitely be a transition we'll have to watch closely as we move out of winter.
