Tawny Crazy Ants Found in Weslaco, Texas

The tawny crazy ant (Nylanderia fulva) was first detected in Texas in Pasadena (Harris County) in 2002.  Since then it has been positively identified in 20 Texas counties.  In 2014 the ants were found at Estero Llano Grande State Park in Weslaco, TX (Hidalgo County).

This species is originally from tropical South America and experts believe that it came to North America through the shipping industry. This invasive species is prolific and can cause damage to infrastructure by infesting and shorting out electrical units. This omnivorous ant can negatively impact wildlife by displacing native ant species and disturbing nesting birds and other small animals.

To survey the park, staff at Estero Llano Grande State Park have been placing ant baits – consisting of a hot dog slice and dollop of mint-apple jelly – in different areas within the park so that they may collect specimens and have them properly identified by the professionals at the Center for Urban & Structural Entomology at Texas A&M University. The staff at Estero Llano Grande State Park has been taking measures to reduce habitat preferred by tawny crazy ants by reducing vegetation within 10 feet of all buildings and removing and burning leaf litter and woody debris surrounding the infested buildings. Certified pest control specialists have been applying pesticides to infested buildings and there has been some reduction in abundance.

Texas Parks and Wildlife Department (TPWD) is working with biologists at University of Texas, Texas A&M University, and Sam Houston State University to develop specific measures that can be implemented on TPWD properties to combat infestations and reduce the potential for spreading.

Invasive Spotlight:
Emerald Ash Borer
(Agrilus planipennis)


First discovered in 2002, the emerald ash borer has killed millions of ash (Fraxinus sp.) trees throughout North America. Recently, this species was found in Louisiana. Emerald ash borer was detected in Webster Parish, making Louisiana the 25th state to be affected by this notorious pest. Read more at MyArkLaMis

To prevent the spread of this beetle and other pests, do not transport firewood from one location to another. When traveling, buy local firewood where you burn it and spread the word in your community. For more information on preventing movement of pests, visit dontmovefirewood.org

Signs and symptoms of an emerald ash borer infestation include die back from the top of a tree, splitting bark, increased woodpecker activity and epicormic growth from the bark.

Wasps Help Scientists Control Carrizo Cane
Carrizo cane (Arundo donax) is goes by the nickname of water thief. It creates a thick stand that crowds out native plants can impact water levels. Scientists are studying the effects a wasp has had on invasive carrizo cane along the Rio Grande. The wasps were released in 2007 and have had a considerable impact on the carrizo cane population, giving hope to researchers that the wasp is an effective control agent. Learn more about the wasp biocontrol at KRGV.

Days Are Numbered For The Tumbleweed
The Russian thistle, or tumbleweed, has become synonymous with the Old West of Hollywood. The tumbleweed’s reign over the Southwest could be coming to an end though. The USDA is working to release a fungus that has been shown to eliminate Russian thistle in other countries. Read more tumbleweed biocontrol at KXWT.

Giant African Snails Seized in Houston

Citrus Greening Quarantine Area Expanded in Texas
The Animal and Plant Health Inspection Service has announced that, effective immediately, the citrus greening quarantine area has been expanded to include all of Willacy County. Tree tissues from the area tested positive for the disease.  Necessary safeguard measures are being implemented to ensure that this disease does not spread.  Read more about this bulletin at APHIS.

Lake Waco: Possible New Method for Battling Zebra Mussels
After finding a zebra mussel colony in September, Lake Waco officials installed a football field- sized tarp on the lake bottom in an effort to control the spread of the colony. Water samples from December 4 have tested negative for zebra mussel DNA and larvae. The tarp remains in place for now. Learn more at The Waco Tribune.

Scientist of the Month
Damon Waitt
‚Äč

The Texasinvasives.org team would like to announce that the Invaders of Texas project director, Dr. Damon Waitt will be leaving the University of Texas at Austin, Lady Bird Johnson Wildflower Center in April. 

Damon played a pivotal role in creating the Texasinvasives.org statewide partnership and citizen science program. In addition to this work, Damon serves on the Invasive Species Advisory Committee for the National Invasive Species Council and is founder of the Texas Invasive Plant and Pest Council. Damon's leadership earned the Wildflower Center the 2013 Outstanding Achievement in Invasive Species Outreach and Education award presented by the National Invasive Species Council. 

When asked for his favorite moments, Damon mentioned his favorites were all firsts--the first time he met Commander Ben, the first Texas Invasive Plant and Pest Conference, the first meeting of the Texas Invasive Plant and Pest Council, the first time the Texas Invasive Plant and Pest Council successfully added a new regulated species to the state noxious weed list and the first Cooperative Weed Management Area meeting in Port Aransas. 

We asked Damon for advice for new citizen scientists joining this statewide program, he stated "It is easy to get discouraged when you first learn about invasive species and start to see them everywhere. Stick with it even though the problem seems insurmountable at best. In the immortal words of Margaret Mead, "Never doubt that a small group of thoughtful, committed, citizens can change the world. Indeed, it is the only thing that ever has."

Damon will now be the Director of the North Carolina Botanical Garden at the University of North Carolina in Chapel Hill, a botanical garden that is a conservation-focused garden, like the Wildflower Center. Learn more by visiting the News Observer.

We wish you the best, Damon and are excited to see you leading the botanical garden!
