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.
Download or read book Field Crop Arthropod Pests of Economic Importance written by Peter A. Edde and published by Academic Press. This book was released on 2021-08-21 with total page 1004 pages. 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 Soil Fertilizer and Plant Silicon Research in Japan written by Jian Feng Ma and published by Elsevier. This book was released on 2002-08-09 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon (Si) plays a significant role in the resistance of plants to multiple stresses including biotic and abiotic stresses. Silicon is also the only element that does not damage plants when accumulated in excess. However, the contribution of Si to plant growth has been largely ignored due to its universal existence in the earth's crust. From numerous intensive studies on Si, initiated in Japan about 80 years ago, Japanese scientists realized that Si was important for the healthy growth of rice and for stability of rice production. In a worldwide first, silicon was recognized as a valuable fertilizer in Japan. The beneficial effects of Si on rice growth in particular, are largely attributable to the characteristics of a silica gel that is accumulated on the epidermal tissues in rice. These effects are expressed most clearly under high-density cultivation systems with heavy applications of nitrogen. Si is therefore recognized now as an ''agronomically essential element'' in Japan. Recently, Si has become globally important because it generates resistance in many plants to diseases and pests, and may contribute to reduced rates of application of pesticides and fungicides. Silicon is also now considered as an environment-friendly element. The achievements of Si research in Japan are introduced in this book, in relation to soils, fertilizers and plant nutrition.

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 238 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.

Download or read book Biodiversity of Fungi written by Mercedes S. Foster and published by Elsevier. This book was released on 2011-04-28 with total page 797 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biodiversity of Fungi is essential for anyone collecting and/or monitoring any fungi. Fascinating and beautiful, fungi are vital components of nearly all ecosystems and impact human health and our economy in a myriad of ways. Standardized methods for documenting diversity and distribution have been lacking. A wealth of information, especially regrading sampling protocols, compiled by an international team of fungal biologists, make Biodiversity of Fungi an incredible and fundamental resource for the study of organismal biodiversity. Chapters cover everything from what is a fungus, to maintaining and organizing a permanent study collection with associated databases; from protocols for sampling slime molds to insect associated fungi; from fungi growing on and in animals and plants to mushrooms and truffles. The chapters are arranged both ecologically and by sampling method rather than by taxonomic group for ease of use. The information presented here is intended for everyone interested in fungi, anyone who needs tools to study them in nature including naturalists, land managers, ecologists, mycologists, and even citizen scientists and sophiscated amateurs. Covers all groups of fungi - from molds to mushrooms, even slime molds Describes sampling protocols for many groups of fungi Arranged by sampling method and ecology to coincide with users needs Beautifully illustrated to document the range of fungi treated and techniques discussed Natural history data are provided for each group of fungi to enable users to modify suggested protocols to meet their needs
