Abstract:
Migratory insects, due to the vast scale of their migration, have a significant impact on both natural ecosystems and human societies. In recent years, increasing attention has been given to the effects of global climate change on insect migration patterns. This review focuses on how altered regional climate patterns affect seasonal prevailing winds and regional precipitation, which then reshape the spatiotemporal patterns and population dynamics of insect migration. However, direct monitoring of these aerial migratory processes is challenged by the small size of insects and the high altitudes at which migration often occurs (hundreds to thousands of meters above ground). There is still a lack of long-term, systematic monitoring data on a global scale, and the impact of climate change on insect migration has not been comprehensively evaluated. How migratory insects respond to climate change and the underlying mechanisms remain to be further studied.
