Due to increasing pyrethroid resistance in the Heliothine population, cotton producers are constantly looking for more economicmeans of controlling these lepidopterous pests. The purpose of this experiment was to examine the effectiveness of selectedinsecticides and compare the efficacy of each for control of a Heliothine population with respect to traditional pyrethroids.The selected insecticides for this experiment were novaluron (Diamond~R), indoxacarb (Steward~R), spinosad (Tracer~R),esfenvalerate (Asana XL~R), lamda cyhalothrin (Karate Z~R), gamma cyhalothrin (DE-225~R), a bifenthrin and spinosad mix(Double Threat~R) Significant differences were observed among treatments in mid to late season observations. Additional dataneeds to be obtained to increase overall significance. The two different application levels of bifenthrin and spinosad thatwere selected for this test had the highest yield increase above the untreated check area. The individual treatment of indoxacarbcontained the least amount of damaged squares across four different evaluation dates with an average of 3.00.
