Insect pests remain a major threat to crop production primarily because of their ability to inflict severe damage on crop yields, as well as their role of key vectors of disease. Early identification of pests is critical to the success of integrated pest management (IPM) programmes and essential for the development of phytosanitary/quarantine regimes to prevent the introduction of invasive insect pests to new environments. Advances in monitoring of native and invasive insect pests of crops provides a comprehensive review of the wealth of research on the preventative measures and monitoring techniques developed to reduce and/or eliminate the risk of alien insect pest invasions which have been exacerbated as a result of climate change. This collection explores advances in techniques for trapping insects, as well as techniques such as remote sensing and radar technology to monitor pest populations and movement, together with DNA and image-based methods for more rapid pest identification.
