Climate change has disturbed ecological balance, food security, sustainability, and human lives. Effects of climate change can adversely affect the pest life cycle, alter pest status, and increase their population which can pose a huge threat to humans around the world. Climate change impacts in urban areas are amplified compared to rural areas since it creates urban warm heat islands which make them warmer. This phenomenon increases pest activity by making pests move to warmer areas. The rise in carbon dioxide (CO2) concentration causes an increase in temperature, which is responsible for critical changes in insect life patterns like behavior, diapauses, and an increase in generation numbers per year. CO2 concentration and temperature are interrelated to each other. CO2 increase leads to an increase in temperature. Also, climate change can lead to the ineffectiveness of natural enemies i.e., an asynchrony in the interaction of pests and natural enemies which can potentially contribute to pest outbreaks. These circumstances drastically reduce crop yields. Combination of climate forecasting and environmental changes can be used to develop models which predict the future pest infestation. Continuous pest monitoring and revised integrated pest management tactics can help to deal this problem.
