Aphids, leafhoppers and whiteflies are responsible for the spread of diseases causing significant crop yield losses globally. On 5 July 2017, the Biosciences eastern and central Africa-International Livestock Research Institute (BecA-ILRI) Hub hosted a symposium to explore ways in which the knowledge of plants, disease-causing organisms and their vectors can be used to combat devastating crop diseases in Africa.

In sub Saharan Africa, the aphid-transmitted bean viruses—bean common mosaic virus (BCMV) and bean common mosaic necrosis virus (BCMNV)—cause up to 100 percent losses for smallholder bean farmers. Growers of cassava—a staple food for over 250 million people— experience losses of up to 23 million tonnes annually across Africa due to disease caused by whitefly-transmitted Cassava mosaic viruses.
In the face of increased regulations on the use of pesticides, a better understanding of the plant-microbe-vector interactions could lead to the development of urgently needed bio pest-controls. The July forum brought together researchers from the BecA-ILRI Hub, Kenyatta University, International Institute of Tropical Agriculture (IITA), Auburn University and North Carolina State University based in Africa; and the John Innes Centre (JIC) from UK.

The symposium was held under the Alliance for Accelerated Crop Improvement in Africa (ACACIA) initiative—a new initiative established to harness diverse research efforts for hastened crop improvement in Africa.
