Relative effectiveness of spinosad and Runner compared with Dursban against pink bollworm, Pectinophora gossypiella infesting cotton green bolls as well as some important predators in cotton fields were evaluated under field conditions at Sharkia Governorate, during 2004 and 2005 cotton seasons. The seasonal average reductions in P. gossypiella infestation attained 86.9, 81.93 and 63.62 in 2004; 84.79, 82.19 and 5.76% in 2005 due to Spinosad, Dursban, and Runner treatments, respectively. Conventional insecticide Dursban resulted in the highest degree of % reduction for all investigated predators, followed by spinosad and Runner, where they recorded general reductions for all investigated predators of 77.44, 49.36 and 42.20% reductions in 2004 season, and 70.71, 49.22 and 35.05% in 2005 cotton season, respectively. Results revealed that spinosad and Runner can be used in the integrated program for the control of the pink bollworm. Spinosad can be used at low or high infestations, while Runner can be applied at the beginning of the season at lower infestations.
