53rd Annual Conference Report on Cotton Insect Research and Control

D. D. Hardee and E. Burris


 
ABSTRACT

There were 14,855,000 acres of U.S. Cotton (Upland and Pima) planted in 1999, 13,381,000acres were harvested with an average of 596pounds of lint per acre (USDA - January, 2000 report).

Arthropod pests of cotton reduced yield by 7.66% in 1999. Cotton fleahopper, exhibiting extremely heavy damage to cotton in Texas, became the top pest of 1999 with 2.36% loss to the US cotton crop. Boll weevil is still a pest on 57% of our US acreage and continues to be the second most damaging pest at 2.20% loss. The bollworm/budworm complex reduced yields by 1.05%. The bollworm was the predominant species to attack cotton in 1999. Bollworms were estimated to make up 71% of the population. Lygus (0.93%), Stink Bugs (0.37%), Thrips (0.27%), and aphids(0.22%) rounded out the top seven cotton insect pests for the year. Beltwide, direct insect management costs amounted to $50.59 per acre and losses were $42.75. Cost plus loss is estimated at $1.269 billion. (see M. R. Williams, this proceedings).
