Establishing Trap Crops to Aggregate and Suppress Spring Populations of Boll Weevil -An Alternative Tactic for Midsouth Eradication Programs

T.G. Teague and N.P. Tugwell


 
ABSTRACT

Studies were continued in 1996 to evaluate the feasibility of incorporating a spring trap crop-pheromone tactic into a boll weevil (Anthonomus grandis grandis Bohemann) eradication program for Midsouth cotton. Trap crops were successfully installed using cotton transplants (plugs) and set in the field using a high speed transplanter. The transplanted cotton, baited with 10 mg boll weevil pheromone lures (1 per 100 ft) and sprayed with ULV malathion applications 2 times weekly, was significantly advanced over commercial cotton (3 wks) and continued to be attractive to boll weevil even after commercial fields began fruiting.
