Viruses are important plant pathogens responsible of yield and quality losses in many crops. Most plant viruses are spread in nature surpassing plant defence barriers with the help of vector organisms, mainly insects. The application of pesticides is an insufficient strategy to stop virus dissemination and, in turn, it can cause important environmental damages. As a consequence, an active area of research is currently devoted to explore alternatives to the abuse of pesticides including, for instance, attempts to unravel the molecular mechanisms operating during insect transmission of plant viruses. All these efforts are aimed to design strategies of interference with the transmission process, which will eventually become part of Integrated Disease Management programmes for the control of virus pathogens. The present chapter reviews the available and potential means to interfere with transmission, and the prospects of such strategies. [ABSTRACT FROM AUTHOR]
