Many of the world's most serious agricultural pests are highly migratory and through the use of special-purpose radars we are provided with insights into their movement and how they learn about, and navigate through, their environment. This text examines the behavior and regional variations of these species, as well as the altitude of migration, concentration of insects in layers and how they respond to large and small-scale wind systems. The book relates radar observation of insect movement to complementary and competing methodologies and surveys its capabilities and limitations. It also deals with the applications of these findings in the management and forecasting of both pest and beneficial insects, and will be an essential reference for those working in agricultural entomology and pest management.

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 as 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 reviews the wealth of research on techniques to monitor and thus prevent threats from both native and invasive insect pests. The book considers recent advances in areas such as sampling, identifying and modelling pest populations. With its considered approach, the book explores current best practices for the detection, identification and modelling of native and invasive insect pests of crops. The contributors offer farmers informed advice on how to mitigate a growing problem which has been exacerbated as a result of climate change.

Migration is a key process in the population dynamics of many insects, including some of the most damaging pests. Multidisciplinary research into the importance of migration, in recent decades, has produced many new insights. This book reviews current understanding of the ecological, behavioural, physiological and genetic bases of insect migration. The first part describes migration systems in Europe, Asia, Africa, Australia, and America, with an emphasis on the role of regional weather and climate. The second part considers insects adaptation to migration; it covers: aerodynamics and energetics; the integration of migration in insect life cycles; environmental and genetic regulation of migratory potential; and the evolutionary implications of habitat heterogeneity and variability. The book then addresses the application of this knowledge to operational pest forecasting.

Multidisciplinary research over the last three decades has produced a series of important new insights.

The second part considers how insects are adapted for migration; it covers aerodynamics and energetics, the integration of migration in insect life cycles, environmental and genetic regulation of migratory potential and the evolutionary implications of habitat heterogeneity and variability. The third part addresses the application of this knowledge to operational pest forecasting. The book concludes with a comprehensive overview of insect migration, written from an evolutionary perspective.
