Boll Weevil Suppression in Rutherford County, TN with Bait Sticks

William L. McGovern, James W. Smith, Eric Villavaso, and Gerald H. McKibben


 
ABSTRACT

An area test of the boll weevil bait stick was conducted in Rutherford County, Tennessee, during 1991 and 1992. During 1991 fields with three or more emerging spring boll weevils were surrounded with bait sticks at the rate of 1 per acre. Most fields were apparently weevil free for 12-15 weeks during the season. In-season boll weevil reproduction appeared to be limited to 1 out of 45 total fields during 1991 in the county. Low levels of migrating weevils were evident during the fall. Distribution of fall trap catches suggest that these weevils may have emanated from a single infested field. Spring trap catches in 1992 were zero and only eight weevils were trapped before August 17. Because no boll weevils were caught early, no control measures were employed during 1992. A large boll weevil migration apparently took place during late season. Trap lines show that this migration was from heavily infested cotton sixty miles or more to the south. This migration reinfested some areas of Rutherford County that had been weevil free for over 12 months.
