In: Annals of Agricultural Science 2006.v.51(2)Summary: Selection pressure under laboratory conditions of the field strain of pink bollworm Pectinophora gossypiella (Saund.) collected from Sharkeya Governorate, Egypt was carried out using the pyrethroid insecticide deltamethrin. The obtained results indicated that the resistance ratio attained a level of 215.11-fold comparing with the susceptible strain after 14 generations of selection. In addition, the response of the obtained deltamethrin resistant strain to some insecticides indicated the cross-resistance to esfenvalerate whereas no cross-resistance occurred to thiodicarb (carbamate), chlorpyrifos (organophosphorus) and/or the bioinsecticides, Dipel 2X and Agerin (derived from Bacillus thuringiensis, subspecies kurstaki). These data may emphasize the possibility of rotation of deltamethrin with these insecticides in pest control program of pink bollworm
