Management of “bois noir” through vector control

Direct and indirect strategies to control Hyalesthes obsoletus, the “bois noir” vector, interfere with the life cycle of this vector and aim at the best possible reduction of infection pressure. Given the complex epidemic system of this disease, effective control attempts can reduce but not eradicate the disease. Coordinated actions of the growers to reduce sources of inoculum at a viticultural site on a larger scale are more promising on the long run than plot-related activities. Further investigations are necessary to identify the factors that drive the long term variation of BN infection pressure in order to setup and improve appropriate preventive measures.
