Book excerpt: Migrant insect pests represent a constant threat to crops and to health in many parts of the world. In Africa alone, over $100 million is spent annually on the control of a half dozen species of locust. One of the key problems in combating migrant pests is that the insect can disappear for months at a time and reappear with catastrophic effect. With the aid of aircraft and radar, it has been possible to map the movements of migrant pests. The research in this book, carried out on an international scale, has shown that migrant pests can travel longer distances than previously suspected and that their movements are related to the dynamics of the winds and weather systems. These findings throw new light on the flight behavior of the insects as well as on the ecological and evolutionary aspects of flight migration and suggest new options for controlling pests, especially locusts and grasshoppers. In surveying the achievements in this area, the author provides the biologist with an introduction to the relevant aspects of meteorology.

Download or read book Insect Movement written by Ian Woiwood and published by CABI. This book was released on 2001 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: Knowledge of insect movement, particularly of flight, is crucial to our understanding of the great ecological and evolutionary success of insects. The last 20 years have seen many advances in this subject area. New fields have arisen, such as metapopulation theory, and dramatic developments have taken place in methods of studying movement, as a result of new techniques in molecular biology and radar monitoring. There have also been advances in our knowledge of flight-related physiology and behaviour. This book, which is based on the main papers presented at the Royal Entomological Society's 20th Symposium held in September 1999, brings us up to date with these developments.It contains chapters on:flight mechanismsforaging movementsmigrationthe evolution of movement strategiesthe interactions between dispersal rates, population structure and gene flow the effects of climate change on geographical distributionIt is essential reading for entomologists, and of interest to those researching animal behaviour, physiology, ecology and genetics.
Download or read book The Biomechanics of Insect Flight written by Robert Dudley and published by Princeton University Press. This book was released on 2018-06-05 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the rain forests of Borneo to the tenements of Manhattan, winged insects are a conspicuous and abundant feature of life on earth. Here, Robert Dudley presents the first comprehensive explanation of how insects fly. The author relates the biomechanics of flight to insect ecology and evolution in a major new work of synthesis. The book begins with an overview of insect flight biomechanics. Dudley explains insect morphology, wing motions, aerodynamics, flight energetics, and flight metabolism within a modern phylogenetic setting. Drawing on biomechanical principles, he describes and evaluates flight behavior and the limits to flight performance. The author then takes the next step by developing evolutionary explanations of insect flight. He analyzes the origins of flight in insects, the roles of natural and sexual selection in determining how insects fly, and the relationship between flight and insect size, pollination, predation, dispersal, and migration. Dudley ranges widely--from basic aerodynamics to muscle physiology and swarming behavior--but his focus is the explanation of functional design from evolutionary and ecological perspectives. The importance of flight in the lives of insects has long been recognized but never systematically evaluated. This book addresses that shortcoming. Robert Dudley provides an introduction to insect flight that will be welcomed by students and researchers in biomechanics, entomology, evolution, ecology, and behavior.

Download or read book Innovative Pest Management Approaches for the 21st Century written by Akshay Kumar Chakravarthy and published by Springer Nature. This book was released on 2020-03-20 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several Integrated Pest Management (IPM) approaches are available for managing pests of varied kinds, including individual and integrated methods for pest suppression. Recently the focus has shifted to pest management tools that act on insect systems selectively, are compatible with the environment, and are not harmful for ecosystems. Other approaches target specific biochemical and physiological aspects of insect metabolism, and involve biotechnological and genetic manipulation. Still other approaches include the use of nanotechnology, endophytes, optical and sonic manipulation to detect and control pest insects. Unfortunately, conventional forms of pest management do not focus on technology transfer to the ground level workers and farmers. As a result, farmers are incurring huge losses of crops and revenues. This book highlights the importance of using communication tools in pest management and demonstrates some success stories of utilizing automated unmanned technologies in this context. The content is divided into three sections, the first of which, “Pest Population Monitoring: Modern Tools,” covers long and short-range pest population monitoring techniques and tools such as satellites, unmanned aerial vehicles/drones, remote sensing, digital tools like GIS, GPS for mapping, lidar, mobile apps, software systems, artificial diet designs and functional diversity of info-chemicals. The second section of the book is devoted to “Emerging Areas in Pest Management” and offers a glimpse of diversified tactics that have been developed to contain and suppress pest populations such as endophytes, insect vectors of phytoplasma, Hymenopterans parasitoids, mass production and utilization of NPV etc. In turn, the third section focuses on “Integrated Pest Management” and presents farming situations that illustrate how research in diversified aspects has helped to find solutions to specific pest problems, and how some new and evolving tactics can be practically implemented. Given its scope, the book offers a valuable asset for entomology and plant pathology researchers, students of zoology and plant protection, and readers whose work involves agriculture, horticulture, forestry and other ecosystems.

Book excerpt: Migration is a key process in the population dynamics of many insects, including some of the most damaging pests. Multidisciplinary research over the last three decades has produced a series of important 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 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.
