Présentation
Plant disease and pest outbreaks have led to major food security crises in Sub-Saharan Africa over the past decades. Examples are the outbreak of cassava mosaic virus (CMV), cassava brown streak virus (CBS), and banana xanthomonas wilt (BXW), just to name a few. These pest and disease outbreaks are often caused by changes in insect population dynamics, either because they are the agent acting as the disease vector or causing direct physical damage to the plant, or because natural insect enemies have not been able to control the insect pest/vector. The population dynamics and behaviour of pests are strongly depending on climatic conditions (i.e. temperature, humidity, winds) and by the presence and condition of host plants that are affected by climate conditions as well. In this activity, we try to understand and model the impact of climate variability and change on majore pest and diseases.
