  1. Recently, the chinese plant protection agencies reported the growing hardships in controlling some field populations of oriental migratory locust with organophosphate ( op ) compounds. up to now there are more than 600 arthropod species with documented resistance to one or more insecticides and / or acaricides since resistance phenomenon was first described in san jose scale to lime - sulfur in washington in 1908. enhanced metabolic detoxification and reduced sensitivity of insecticide target - sites are the two major mechanisms in resistance development, involving three primary metabolic enzymes of esterases, glutathione s - transferases and cytochrome p450 polysubstrate monooxygenases
