Book excerpt: Planthoppers include some of the most devastating pests of major agricultural crops throughout the world. One species, the rice brown planthopper, is among the most economically important pests in Asia. In past decades, government policies encouraged the control of rice planthoppers with synthetic pesticides, a tactic which promoted insecticide resistance and often led to the pesticide-induced resurgence of pest populations. To deter planthopper outbreaks, a more ecologically sound management strategy is being implemented, one based on a thorough investigation of population dynamics, natural enemies, and the genetics of host plant and insecticide adaptation. In the natural habitats of North America and Europe, scientists have also used planthoppers as model organisms to test ecological and evolutionary theory. The consequence of these diverse studies is an extremely scattered literature on planthoppers that has never been synthesized from an ecological perspective. This volume summarizes what is known about planthopper ecology and biological control. It takes a theoretical approach yet is deeply concerned with the application of theory to the practical problems of pest management.

Available in PDF, EPUB and Kindle. Book excerpt: Recent studies have shown that genetic polymorphisms play an important role in structuring the seasonal life cycles of insects, complementing an earlier emphasis on the effects of environmental factors. This book presents current ideas and recent research on insect life--cycle polymorphism in a series of carefully prepared chapters by international experts, covering the full breadth of the subject in order to give an up-to-date view of how life cycles are controlled and how they evolve. By consolidating our view of insect life--cycle polymorphism in this way, the book provides a staging point for further enquiries. The volume will be of interest to a wide variety of entomologists and other biologists interested in the control and evolution of life cycles and in understanding the extraordinarily complex ecological strategies of insects and other organisms.

Download or read book Rice Planthoppers written by Kong Luen Heong and published by Springer. This book was released on 2014-10-23 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book discusses planthopper pests of rice. These insects are one of the most destructive pests, threatening food security around the world. The historical development of the rice planthopper problem shows that they are secondary pests and single-discipline control tactics or strategies were not able to manage them, and instead caused frequent resurgences. This book not only presents new approaches to this persistent problem, but also new ecological methods, new perspectives on the effect of pesticide marketing, insights into developing resistant varieties and structural reforms in pest management. Integrating biological, ecological, economic and sociological aspects, it clearly presents the latest information on newly developed strategies for managing this pest. Dr. K. L. Heong is the principal scientist and insect ecologist at the International Rice Research Institute, Philippines. He has been researching rice planthoppers for more than 30 years. Dr. Heong is a fellow of the Third World Academy of Science and the Academy of Sciences, Malaysia. Professor Jia-an Cheng is an insect ecologist who has been studying rice planthoppers for about 50 years. He is a professor at Zhejiang University, China. Professor M.M. Escalada works at Visayas State University.

Available in PDF, EPUB and Kindle. Book excerpt: The field guide documents the community of insects that feed on rice in the tropical zone of Asia and complements the IRRI publication "Helpful insects, spiders, and pathogens: friends of the rice farmers." It covers 78 phytophagous species in 64 genera, 27 families, and 8 orders. The phytophage guild represents five groups-general defoliators, (27 species), plant suchers (25 species), early vegetative pests (11 species), soil pests (9 species), and stem borers (6 species). Stem borers and plant suckers comprise the major rice pests. A brief description of each insect's life stage and demage it does to the rice plant is presented for a quick and reliable identification.

Available in PDF, EPUB and Kindle. Book excerpt: Field Crop Arthropod Pests of Economic Importance presents detailed descriptions of the biology and ecology of important arthropod pest of selected global field crops. Standard management options for insect pest control on crops include biological, non-chemical, and chemical approaches. However, because agricultural crops face a wide range of insect pests throughout the year, it can prove difficult to find a simple solution to insect pest control in many, if not most, cropping systems. A whole-farm or integrated pest management approach combines cultural, natural, and chemical controls to maintain insect pest populations below levels that cause economic damage to the crop. This practice requires accurate species identification and thorough knowledge of the biology and ecology of the target organism. Integration and effective use of various control components is often enhanced when the target organism is correctly identified, and its biology and ecology are known. This book provides a key resource toward that identification and understanding. Students and professionals in agronomy, insect detection and survey, and economic entomology will find the book a valuable learning aid and resource tool. Includes insect synonyms, common names, and geographic distribution Provides information on natural enemies Is thoroughly referenced for future research

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.

This book was released on 2010-03-25 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract This chapter defines food security as the condition reached when a nation’s population has access to sufficient, safe, and nutritious food to meet its dietary needs and food preferences. It stresses China’s importance to global food security because of its population size. The chapter introduces the contents of the volume and then treats briefly food security in ancient and dynastic (211 bc–1912) China. It examines environmental stressors, such as population growth, natural disasters, and insect pests as well as imperial responses (for example, irrigation, flood control, storage and transportation systems). The chapter also briefly int- duces the Republican era (1912–1949) and compares environmental stressors and government responses then to those of the imperial period. Keywords Food system • Food security • Food production regions • Environmental stressors (Population growth • Natural disasters • Insect pests and Plant diseases • Deforestation • Climate change) • Irrigation systems • Flood control • Grand Canal 1. 1 The Problem of Food Security and Environmental Change Food is the material basis to human survival, and in each nation-state, providing a system for the development, production, and distribution of food and its security is a primary national objective. Many forces have influenced the food security of peoples since ancient times, with particular challenges from natural disasters (floods, famines, drought, and pestilence) and growing populations globally.
