**9. Conclusion**

Climate change has created a new ecological niche and opportunities are provided for vectors to continuously expand their geographic region. Hence, the migrating behaviour. Microscopic plant pathogens and vectors who spend most of their life underground have a comparatively greater advantage of surviving climate change as soil is a thermal insulating medium, buffering temperature change and reducing impact. Apart from the focus of climate change being the increase in global temperature, the change in climate is contributed by human activities where the atmospheric composition changes. The significant gas that all scientists are studying is the carbon dioxide concentration. The increase in carbon dioxide concentration has driven vegetation shift. However, it has also driven the susceptibility of pathogens of these vegetation. High carbon dioxide levels can encourage plant growth. However, it will encourage the feeding for insects as vegetation increases in palatability.

The change in the ecosystem is tied in closely to that of insects and pathogens. Therefore, the change in climate will strongly affect the survival of the vectors of diseases rather than the diseases itself. This can be supported by the expansion of diseases as the vectors expand their movement through migration. The behavioural changes in vectors are significant and as they strive and adapt to the change in climate, so will the plant diseases in grassland continue to cause more damage.
