Impacts of Climate Change on Insect Pests of Main Crops in Egypt

Climate change is expected to have a negative or positive effect on the short and long term on the diversity of pest’s abundance, pest’s–host plant interactions, an abundance of natural enemies, and finally the extent of damage to the Egyptian economy due to the impact on agricultural economic crops. Under current and previous climatic conditions, major crops and their pests have adapted to climatic elements that help them to survive, grow, reproduce, and spread, based on host abundance and interaction. The significant change in climate is reflected in the increase in the average temperature of the globe, the change in precipitation amounts, their patterns, and their locations. These seasonal and long-term changes will affect the crops grown regarding production and components, the emergence of new plant species that were not previously known. In other words, any change in the components of the environment will be reflected in human lifestyles and the pests associated with their crops. In studies under laboratory conditions, climate components directly affected insect dynamics by modifying growth, survival, fertility, dispersion, and differentiation.
