【Abstract】 Research of integrated pest management on wheat was carried out in Tianshui Prefecture, Gansu Province during 1986-1990. Based upon the population dynamics of local main wheat pests, especially wheat stripe rust, and their characteristics of occurrence and damage to wheat, complete sets of the practical multi-function control techniques have successfully been exploited, and the system of integrated pest management (IPM) on wheat has primarily been established.
