Attract 'N Kill Approaches for Effective Cotton Insect Control

Sheldon R. Murphy


 
ABSTRACT

Newer methods of combining natural insect attractants with insecticides are needed to improve insecticide effectiveness, hedge against insect resistance buildup, preserve the beneficials in early season control programs and provide cost/yield benefits for the grower. The Attract 'n Kill concept, using synthetic insect attractants in microtube dispensers coated with an insecticide, were tested on PBW since the early 80's and have undergone commercial field trials in 1983-84 with much success. Usage with insecticide, often pyrethroids, at 5% of the normal rate, is effective for early to mid season control of PBW in AZ/CA - an improvement over mating disruption methods used since 1976. Later season applications of Attract 'n Kill Plus, and insecticide overspray at lower than standard rates, boosted insecticide effectiveness. This Dual application provides hot adult and larval control. Often Attract 'n Kill Plus controlled where insecticides alone were insufficient. Longer intervals before respraying and reduction of 1st and 2nd generation PBW populations resulted in lower season control costs with higher yields.
