How can climate change affect pest populations in agriculture?

Climate change can significantly impact pest populations in agriculture by expanding their habitats. As temperatures rise and weather patterns shift, many pests can thrive in regions that were previously unsuitable for them due to cooler temperatures or less favorable conditions. Warmer temperatures can lead to longer growing seasons for both crops and pests, allowing pests to reproduce more frequently and spread into new areas. Additionally, changes in precipitation can create environments that support pest survival and growth, such as increased humidity enabling the proliferation of certain insects and diseases.

With pests moving into new areas, they may encounter less genetic resistance in crops that have not evolved to counter these species. Consequently, the expansion of pest habitats can result in increased agricultural damage and higher levels of pest-related economic losses, making it a critical consideration in agricultural practices and pest management strategies in response to climate change.
