In 1978, when Russian wheat aphid was first recorded on wheat in the Free State Province of South Africa, little information regarding the control of this devastating pest was available. Large-scale use of insecticides was the order of the day for many years, but now, after concerted research efforts, farmers are planting resistant cultivars to control this pest. The question is whether these cultivars will provide durable control of Russian wheat aphid. This paper discusses strategies and methods that are being used in breeding for durable resistance. In addition to host plant resistance, other control options, such as biological control using natural enemies like parasitoids and predators as well as entomopathogenic fungi, are being explored in order to integrate them with resistant cultivars to provide an effective and environmentally sound integrated control program for this pest.
