Human activities that alter the greenhouse gases concentrations will have a direct influence on plant health issues. In order to minimize both the production loss and the quality, and to guide the choice of adaptation strategies and management, further studies to investigate the impacts of climate change on agriculture - in the spatial and temporal scales - and their pathogens are needed. The main goal of this work was to explore the global climate impact on the ecoclimatology of the citrus blackfly (Aleurocanthus woglumi Ashby) in State of Pará. To do so, the thermal requirements of Aleurocanthus woglumi Ashby developed in laboratory and on the ecoclimatological zoning based on the annual insect population was first analyzed using air temperature data series from 15 meteorological stations. Then, the populational increase of the studied insect through the projections of global climate model CCSM 3.0, between years 2030 and 2090, was simulated and analyzed. The results of simulations suggest that the number of generations of the insect will increase 50% in Pará state.
