Biotopic status of the Russian Wheat Aphid in correlation to resistant barley lines in Ethiopia

| Coordinating organisation: | Institute of Forest Entomology, Forest Phytopathology & Forest Protection |
| Description: | The Russian Wheat Aphid RWA, Diuraphis noxia (Mordvilko), is an insect pest on barley, Hordeum vulgare, and bred wheat, Triticum aestivum, in the Highlands of Ethiopia. Estimated yield losses of barley caused by RWA ranged between 41 to 79% in the last years. s local subsistence farmers mainly cultivate barley, control of the pest is achieved predominantly through the use of resistant barley lines. A number of barley lines with resitance to RWA were identified and released to farmers in Ethiopia. However, biotypic variability of RWA can render control with host-plant resistance. Such RWA biotypes can develop as a result of selection from the parent population in response to exposure to resistant cultivars. |
