Abstract: The recent development of novel sequencing technologies and bioinformatics has greatly facilitated the fundamental and applied studies on insect genomes with the steady increase of accomplishments. Studies that integrate variables of agricultural landscape with the genomic structure, genetically adaptive variation, and gene functions aid in better understanding of the molecular mechanisms associated with the adaptability and infestation of a target pest in a specific landscape framework, providing new thoughts and directions for pest management. Landscape genomics is an interdisciplinary subject combining landscape ecology with population genomics and aims to examine the genetic basis of adaptation of a given species to changing environments. Landscape genomics mainly focus on the investigation and analysis of adaptive evolution in species as well as gene flow and genetic drift among populations that are under environmentassociated selection. The research methodology of landscape genomics can be generalized as the design of spatial sampling strategy, utilization of molecular markers, and data collection and analysis. In this article we reviewed the research status of landscape genomics including the major findings and achievements in recent years. Further, we elaborated the application and prospects of landscape genomics in the aspects of insecticide resistance management, conservation biological control, and integrated pest management in the context of global climate change, with the ultimate goal of reducing the use of insecticides and promoting the safe production of crops.

Key words:  Landscape genomics, genetics, adaptation, evolution, transgenic crops; insecticide resistance, global warming
