Texas Boll Weevil Eradication Foundation, Inc.


Welcome to the Texas Boll Weevil Eradication Program web site. This site has been developed to provide information to cotton producers and the general public about the process and progress of boll weevil eradication across the state.

2010 Program Year End Summary

The Texas Boll Weevil Eradication Foundation (TBWEF) completed a successful year in 2010. Program activities were carried out in 16 Texas and four eastern New Mexico zones on 6,070,792 mapped land acres of cotton.

North and West Texas

In the West Texas zones, the boll weevil eradication program showed good progress in 2010. Only 15 weevils were caught from the 5,324,749 mapped cotton acres in the 11 West Texas zones during the year. Of those, 10 weevils were caught on the southern edge of the Southern Rolling Plains (SRP) zone, and five were caught on the eastern edge of the zone. The 10 weevils are believed to have originated from the South Texas/Winter Garden (ST/WG) zone and moved into the SRP after September 29, 2010. Four fields in Coleman County captured an additional five weevils over a six week period with a total of not more than two weevils in a field. There was no evidence of reproduction in any of the West Texas zones.

South and East Texas

Weather was the limiting factor the program encountered in the South and East Texas zones. In spite of this, 79,433 fewer weevils were caught in these zones than in 2009, a 26 percent reduction. Boll weevil captures were down in the ST/WG, Northern Blacklands (NBL), Upper Coastal Bend (UCB), and the Southern Blacklands (SBL) zones compared with the previous year. The UCB zone caught a single weevil, while the NBL zone caught three. Program treatments in these zones were aggressive during the early season. Volunteer cotton and cotton plants growing in failed cotton fields planted to grain sorghum were addressed by growers, and volunteer cotton was less of a problem in 2010.

In the Lower Rio Grande Valley (LRGV) zone, however, hurricanes and storms significantly affected program operations and spread weevils across the zone. The impact of the storms in the LRGV disrupted trapping and treatment operations. Flooding conditions continued for 60 days following the tropical weather due to extended releases from dams upriver. The LRGV was also impacted by the Mexican program in the state of Tamaulipas. Growers there did not treat fields for boll weevils following the tropical weather which lead to a significant buildup of weevils along the river.


Statewide, the acreage planted to cotton in Texas in 2010 was up 617,504 mapped acres (11 percent) from the previous year, and the 2010 cotton crop was the third largest on record in Texas in terms of total production to date. Record Texas cotton crops have been recorded in four of the last seven years. In fact, prior to 2004 there had not been a record setting cotton crop in 58 years. This is significant because the recent record-breaking production occurred after boll weevil had been removed as an economic pest. In the last seven years, yields have averaged 707.28 pounds per acre. Compared to the seven years prior to 2004 when yields averaged 487.85 pounds per acre, yields in the last seven years have increased by 219.43 pounds per acre.
