2017 Program Year End Summary

The Texas Boll Weevil Eradication Foundation (TBWEF) completed a successful year in 2017. Boll weevil eradication activities were carried out in all Texas and eastern New Mexico cotton fields, on a total of approximately 7.275 million certified land cotton acres. For the year, only two zones reported weevil captures. Boll weevil captures occurred in the Lower Rio Grande Valley (LRGV) and the South Texas Winter Garden (STWG) zones.

Beginning in 2015, program operations in eleven West Texas eradication zones were combined into one Maintenance Area. Those eleven zones, now part of the West Texas Maintenance Area (WTMA), are: Southern Rolling Plains (SRP), El Paso/Trans Pecos (EPTP), St. Lawrence (STL), Permian Basin (PB), Rolling Plains Central (RPC), Western High Plains (WHP), Southern High Plains/ Caprock (SHPC), Northern Rolling Plains (NRP), Northern High Plains (NHP), Northwest Plains (NWP), and Panhandle (PH). South Texas Winter Garden (STWG), Upper Coastal Bend (UCB), Southern Blacklands (SBL), and Northern Blacklands (NBL), were combined into the East Texas Maintenance Area (ETMA) in late 2016 and operated in 2017 as one entity. The combining of these zones increases efficiency tremendously which lowers program operating cost for the Texas program. The Lower Rio Grande Valley (LRGV), continues to operate as an individual zone.

Below is a map illustrating the opational boundaries after the establishment of the WTMA and the ETMA:


West Texas Maintenance Area (WTMA)


I2017 proved to be another excellent year for boll weevil eradication in the WTMA. A total of 6.144 million acres were planted to cotton in the WTMA. Acres were up in this part of the state due to low prices for other crops. The trap density in the WTMA is one trap per square mile where cotton is planted. There were no boll weevils captured and no acres treated. In 2015, the WTMA was declared eradicated by the Texas Department of Agriculture.

East Texas Maintenance Area (ETMA)

The ETMA planted approximately 937,230 acres of cotton in 2017. Up from approximately 780,747 acres planted in 2016. The increase in acres in this region of the state was due to optimal rainfall and growing conditions plus competing crops provided much lower returns on investment. The Winter Garden area near Uvalde was the only area in the ETMA where weevils were captured in 2017. This area was weevil free for three years until a migration event transported boll weevils from the LRGV zone in 2015 and 2016. There were 1,292 weevils captured in 2017 in this area compared to 15,714 in 2016. In 2017, fields within a mile of any field that captured the previous year or captures occurring during the 2017 season had traps deployed at one trap every 1/10th of a mile per the protocol developed by the Texas Technical Advisory Committee. Treatments were initiated on all fields capturing weevils as well as adjacent fields. A total of 158,734 acres were treated in 2017 compared to 151,463 treated in 2016 in the STWG area of the ETMA.


Lower Rio Grande Valley Zone (LRGV)


The 2017 boll weevil captures represent the lowest number of boll weevils captured in the zone since the program began. As of December 31st, the LRGV zone captured 34,544 boll weevils, compared to 174,640 weevils captured in 2016 and treated 751,444 acres in 2017. Trap density in this zone is one trap per five acres. Significant progress was also made in the LRGV zone during the 2017 growing season due to increased collaboration with Tamaulipas, Mexico. Foundation personnel worked closely with Tamaulipas personnel to increase the effectiveness of their program and encourage program improvements. The Information Technology department of TBWEF asisted Tamaulipas with upgrades to their hardware and software that will enable Texas personnel to contiue to assist the Tamaulipas program with managing the different aspects of eradication. This cooperating conatinues to assist Texas in the eradication effort by lowering weevil migration.
