2018 Program Year End Summary


The Texas Boll Weevil Eradication Foundation (TBWEF) completed a successful year in 2018. Boll weevil eradication activities were carried out in all Texas and eastern New Mexico cotton fields, on a total of 7.9 million land acres of cotton (Table 1). 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) zone in the East Texas Maintenance Area (ETMA).

West Texas Maintenance Area (WTMA)

 

2018 proved to be another excellent year for boll weevil eradication in the WTMA. A total of 6.6 million acres were planted to cotton and no weevils were captured. Cotton acres increased in this part of the state is due to low prices for other crops. Traps are placed in a grid pattern at a density of one trap per mile where cotton is planted. In 2015, the WTMA was declared eradicated by the Texas Department of Agriculture.


East Texas Maintenance Area (ETMA)

Farmers on the ETMA planted 1.1 million acres of cotton in 2018, up from 937,000 acres planted in 2017. Boll weevils were captured in two areas of the ETMA, in the Winter Garden and in the Coastal Bend. In 2015, boll weevils were captured in the Winter Garden area near Uvalde. This area had been weevil free for three years before being re-infested with weevils migrating from the LRGV zone and/or Tamaulipas, Mexico. A total of 73 weevils were captured in 2015, 15,714 in 2016 and 1,292 in 2017. Significant progress was made in 2018 in this area, with only 42 weevils captured season long. Six of these weevils were captured in January and 35 were captured after defoliation in a field located close to a gin in Batesville. No weevils were captured through the growing season. In mid-July, weevils were captured in a field South of Kingsville. A total of 283 weevils were captured in five different locations spanning from Kingsville to Odem. These weevils were most likely transported into the area from either the LRGV zone or Tamaulipas. Trapping was increased in this area and treatments made according the protocol established by the Texas Technical Advisory Committee (TAC).

 

Lower Rio Grande Valley Zone (LRGV)

 

A total of 96,346 boll weevils were captured in the LRGV zone in 2018, an increase from the 34,544 weevils captured in 2017. The Foundation treated 870,678 acres of cotton in 2018, compared to 749,044 acres of cotton treated in 2017.

Several factors contributed to the increased weevil numbers in LRGV. The primary reason for the increase in weevils was the lack of proper stalk destruction in Tamaulipas, Mexico in late 2017. Proper stalk destruction was not carried out and treatment of these hostable plants did not take place. This allowed weevil populations to increase last fall, resulting in a significant overwintering population in the spring of 2018. Prior to the buildup in late 2017, significant progress had been made on both sides of the river during the 2017 growing season. Failure to destroy cotton stalks in Tamaulipas after harvest in 2017 resulted in significant weevil buildup and migration into Texas.
