2016 Program Year End Summary

West Texas Zones (WTMA)


In the West Texas zones (WTMA), 2016 proved to be another excellent year for boll weevil eradication.  In the 4.8 million land acres that make up the 11 West Texas zones in 2016, there were no boll weevils captured and there were no acres treated.  All 11 West Texas zones have been declared eradicated.

South and East Texas Zones

The South and East Texas zones planted approximately 780,747 acres in 2016, up from approximately 479,000 acres in 2015. The East Texas Maintenance Area consisted of 645,693 acres from the total 780,747.   The LRGV and STWG zones were the only zones in the United States to capture weevils in 2016.  As of December 13th, the LRGV zone had captured 174,647 boll weevils, compared to 148,674 weevils captured in 2015. These captures were primarily located near the Rio Grande River and adjacent to Mexico.  The LRGV treated acreage in 2016 was 680,932 acres compared to 441,212 in 2015.  The LRGV zone continues to experience challenges in the program.  Some of the high weevil count fields are located in drug trafficking areas and there are safety issues associated with trap inspection and treatment.  Most weevil captures are occurring in the border area along the Rio Grande River.  Northern Mexico did not plant cotton in 2009 and the LRGV experienced greatly reduced numbers at that time.  Since then weevil numbers have failed to decrease. The National Cotton Council initiated an International Technical Advisory Committee to improve communication and enhance program progress on both sides of the border. The Texas program has taken several steps to assist the Tamaulipas program in 2016.  The Texas program has assisted the Tamaulipas program with procuring additional ground treatment equipment. This equipment will enable the Tamaulipas program to treat acreage late in the season and also treat areas of fields that in the past were not treated by aerial spraying because of obstacles. Over the past few months, program personnel from Texas have met frequently with Tamaulipas program personnel in order to exchange information and educate Mexico’s program personnel on proper protocols that must be followed in order to have an effective eradication program. The TBWEF Information Technology department has assisted the Tamaulipas program with modern computer hardware and software upgrades that will enable Texas personnel to assist the Tamaulipas program with managing the many aspects of eradication. These technology upgrades allow for both programs to communicate what is happening across the river in Mexico and will further educate them on how to conduct an effective program. The threat of violence in Mexico has not allowed program personnel to communicate effectively because it’s too dangerous for personnel in Texas to travel to Mexico. The goal of this new approach is strengthen the relationship with both countries and ultimately achieve the goal of eradication.    


An area of reproduction was also discovered in a field near Dilley (STWG) very late in the 2015 season and is presumed to be a result of migration out of the LRGV.  No other area of reproduction was found in 2015 in the STWG zone. In 2016, weevils were captured in an area north and west of this 2015 field.   Fields in the area had traps deployed at 1/10 per acre as a result of protocol developed by the Texas Technical Advisory Committee. Treatments were initiated on all fields capturing weevils as well as adjacent fields. A total of 151,603 acres were treated in 2016 compared to 7,841 treated in 2015.  This area also captured 15,353 weevils compared to 73 weevils captured in 2015. A field was found in November that had not been found by eradication personnel.  This field accounted for more than 40% of all weevils found in the area. Another area of reproduction was discovered near Alice, Texas on August 4th.  A total of nine weevils were captured in this area with the last weevil captured the week of September 1st.  There have been no weevil captures since that time.  A total of 13,677 acres were treated as a result of this infestation.


In December 2015, fields were found in Maverick County that contained a boll weevil infestation.  This county had not planted cotton since the 1950’s and a producer from the Edinburg area moved his cotton operation into this area. Although this area is located in the LRGV, it is very near the Uvalde district of STWG and poses a threat to the cotton in this area. Eradication efforts began in 2015 with traps deployed on fields where cotton had been planted and in the spring of 2016, treatments were initiated on fields with volunteer cotton.  No cotton was planted in Maverick County in 2016 and the last week in which weevils were captured was June 13th.
