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.

Available in PDF, EPUB and Kindle. Book excerpt: The four-day international Conference on Pest Management in Rice, which is the subject of this volume, was the third in an ongoing series of meetings on tropical crops organised by the Pesticides Group of the Society of Chemical Industry, London. The participants came from both the public and private sectors and from many different countries. All the major groups of pests-weeds, microorganisms, arthropods and rodents-were considered, as the organisers believe that it is necessary to address the total pest management problems in each particular growing area, and the variety of the papers indicates the importance of a multi disciplinary approach to their solution. Rice is one of the most important world crops and is the major source of food for around 60% of the world's population, with a world production of 500 million tonnes from 150 million hectares of land. Since world stocks amount to only two months supply, many people are at risk from famine. Moreover, it has been esti mated that the world requirement in 2020 will be about 760 million tonnes, an increase of 50%. This pressure of population on food makes efficient pest management vital and is the reason for bringing together experts from all over the world to this major conference.
