AbstractIn modern agroecosystems, natural plant communities are usually modified to meet the special needs of humans with a specific species of cultivated crops grown over a vast area. Relationships between crop plants, and pest insects and their natural enemies, are an important part of the agricultural landscape system. Understanding the effects of agricultural landscape patterns on the population dynamics of insects can play an important role in sustainable pest management. In this paper, we first define some conceptions about agricultural landscape patterns then discuss the effects of agricultural landscape patterns on pest insects and their natural enemies. Finally, we summarize the current status of research in this field and provide suggestions for future research.
