Introductory remarks

Vector-borne plant diseases are intensifying worldwide as climate change, ecological shifts, and agricultural practices reshape the dynamics between insects, hosts, and pathogens. This session features studies from California, Florida, Brazil, Saskatchewan, and Israel, offering a global perspective on how vector populations and their associated microbes respond to environmental pressures. Topics include the identification of potential insect vectors in new agroecosystems, the influence of endosymbionts on transmission efficiency, and behavioral and physiological responses of vectors under biotic and abiotic stress. Together, these presentations highlight how climate-driven range expansions and host shifts are fostering the emergence of novel plant disease systems. The session will conclude with a panel discussion on integrative strategies to anticipate and manage vector adaptation in a changing world.
