Climate change strongly affects the occurrence and spreads of viral diseases in fruit crops, posing serious threats to agricultural productivity and food security. Rising temperatures and altered rainfall patterns and distribution disrupts the fruit tree’s physiology and phenology, creating favorable conditions for the emergence of new viral strains and the resurgence of existing ones. Moreover, climate changes also impact the life cycles and geographic distribution of insect vectors accelerating the virus transmission, replication and systemic movement within the host plants. Climate change also possesses challenges in management of the viral diseases, leading to significant yield and quality losses. Integrated strategies combining resistant cultivars, adaptive vector management, quarantine measures, and advanced forecasting tools alongside deeper research into virus-vector-host-climate interactions, will be essential to mitigate future climate-driven viral threats.

摘要

Climate change strongly affects the occurrence and spreads of viral diseases in fruit crops, posing serious threats to agricultural productivity and food security. Rising temperatures and altered rainfall patterns and distribution disrupts the fruit tree’s physiology and phenology, creating favorable conditions for the emergence of new viral strains and the resurgence of existing ones. Moreover, climate changes also impact the life cycles and geographic distribution of insect vectors accelerating the virus transmission, replication and systemic movement within the host plants. Climate change also possesses challenges in management of the viral diseases, leading to significant yield and quality losses. Integrated strategies combining resistant cultivars, adaptive vector management, quarantine measures, and advanced forecasting tools alongside deeper research into virus-vector-host-climate interactions, will be essential to mitigate future climate-driven viral threats.
