This study analyzed the biological characteristics, ecological roles, evolutionary adaptation mechanisms and population dynamics of herbivorous insects in agricultural ecosystems, discussed the classification and ecological habits of herbivorous insects, their impact on agricultural production and ecological network functions, and the concept of adaptive evolution unique to agricultural environments, focusing on the evolutionary adaptation mechanisms of herbivorous insects in terms of nutrient utilization, behavioral sensory perception and pesticide resistance. At the same time, the driving factors of their population dynamics were explored, including environmental factors, agricultural management measures and the impact of climate change. Through typical cases such as cotton bollworm, whitefly, Spodoptera litura, and rice planthopper, the phenomenon of multi-host adaptation, resistance evolution, population replacement and global expansion of herbivorous insects was analyzed. This study also looks forward to future research directions, such as multi-omics integration to reveal adaptation mechanisms, precision agriculture and population prediction models, biological regulation and ecological agriculture strategies, and adaptive evolution risk assessment under the background of climate change, in order to guide sustainable integrated pest management and provide reference for the stability of agricultural ecosystems and food security.
