Abstract

Increased temperatures, rising CO2 levels, and changing precipitation patterns are influencing agricultural production. These changes can lead to the expansion of insect pests geographic distribution, increased survival during overwintering, more generations per year, altered synchrony with plants, changed interspecific interactions, higher risk of invasion by migratory pests, increased incidence of insect-transmitted plant diseases, and reduced effectiveness of biological control. There is a serious risk of economic losses in crop production. Human food security is challenged due to potential disruptions in agricultural systems. Climate change necessitates adaptive management strategies to address evolving pest dynamics. Future research should focus on developing modified integrated pest management tactics to cope with changing pest statuses. Monitoring climate and pest populations is crucial for understanding and predicting the impact of climate change on insect pests. This review examines the climate change effect on insect pest biology and behavior and explores the potential use of modern pest monitoring technologies, modeling prediction tools can aid in forecasting and planning for potential pest outbreaks. Integrated pest management (IPM) approaches should be adapted to incorporate the changing dynamics influenced by climate change. This may involve a combination of chemical, biological, cultural, and mechanical control methods.
