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: 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 Management of Insect Pests to Agriculture written by Henryk Czosnek and published by Springer. This book was released on 2016-01-08 with total page 291 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thanks to the application of new technologies such as whole-genome sequencing, analysis of transcriptome and proteome of insect pest to agriculture, great progress has been made in understanding the life style, reproduction, evolution and nuisance to crops caused by insect pests such as aphids, planthoppers, and whiteflies. We believe that time has come to summarize progress and to have a glance over the horizon. In this Book experts in the field discuss novel means to increase the different kinds of resistances of plants to better limit the effects of pest, to understand and disturb the hormonal regulation of embryogenesis, molting, metamorphosis and reproduction, to determine the function of insect genes in diverse processes such as metabolism, interaction with plants, virus transmission, development, and adaptation to a changing environment. The knowledge presented here is discussed with the aim of further improving control strategies of insect pestsman";mso-hansi-theme-font:minor-bidi;mso-bidi-theme-font:minor-bidi; mso-ansi-language:NL;mso-fareast-language:NL;mso-bidi-language:AR-SA">.
Download or read book Biology of the Plant Bugs Hemiptera Miridae written by Alfred George Wheeler and published by Cornell University Press. This book was released on 2001 with total page 558 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant bugs--Miridae, the largest family of the Heteroptera, or true bugs--are globally important pests of crops such as alfalfa, apple, cocoa, cotton, sorghum, and tea. Some also are predators of crop pests and have been used successfully in biological control. Certain omnivorous plant bugs have been considered both harmful pests and beneficial natural enemies of pests on the same crop, depending on environmental conditions or the perspective of an observer.As high-yielding varieties that lack pest resistance are planted, mirids are likely to become even more important crop pests. They also threaten crops as insecticide resistance in the family increases, and as the spread of transgenic crops alters their populations. Predatory mirids are increasingly used as biocontrol agents, especially of greenhouse pests such as thrips and whiteflies. Mirids provide abundant opportunities for research on food webs, intraguild predation, and competition.Recent worldwide activity in mirid systematics and biology testifies to increasing interest in plant bugs. The first thorough review and synthesis of biological studies of mirids in more than 60 years, Biology of the Plant Bugs will serve as the basic reference for anyone studying these insects as pests, beneficial IPM predators, or as models for ecological research.

Download or read book Viruses Threatening Stable Production of Cereal Crops written by Nobuhiro Suzuki and published by Frontiers Media SA. This book was released on 2015-07-17 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cereal crops such as maize, wheat, and rice account for a majority of biomass produced globally in agriculture. Continuous economic and population growth especially in developing countries accompanied more intensive production of cereal crops to meet increasing demands for them as main staple foods and livestock feeds. However, imbalance between production and consumption of cereal crops, which is inevitably reflected as their higher market prices, is becoming palpable in recent years. Stable production of cereal crops has been threatened by various abiotic and biotic stresses. One of the most threatening constraints is virus diseases. Especially, intensification of cereal crop production is often achieved by monoculture of a popular crop variety in a wide area. Such agroecosystems with low biodiversity is usually more conducive to biotic stresses, and may result in the outbreaks of existing and emerging cereal viruses. Numerous reports on incidences of various virus diseases of cereal crops attested that viruses have been a long-standing obstacle eroding yields of cereal crops worldwide. Despite of the evident economic losses incurred by virus disease of cereal crops, the progress in basic research on virus species causing major diseases of cereal crops lagged behind compared to that carried out for viruses that can infect dicotyledonous plants. This was partially due to the lack of ideal experimental systems to investigate the interaction between viruses and monocotyledonous crops. For example, inoculation of many viruses to cereal plants still requires tedious manipulation of vector organisms, and reverse genetic systems are not available for many cereal viruses. However, application of latest molecular biology technologies has led to significant advance in cereal virology recently; transient gene expression systems through particle bombardment and agroinfiltration have been exploited to examine the functions of cereal virus proteins. Cell culture systems of vector insects enabled to investigate the molecular interactions between cereal viruses and insect vectors. Furthermore, RNAi technologies for vector insects and monocotyledonous plants facilitated identification of specific host and viral factors involved in viral replication and transmission cycles. Also, accumulating information on the genome sequences of cereal crop species has been simplifying the roadmap to pinpoint resistance genes against cereal viruses. The objective of this research topic is to provide and share the information which can contribute to advances in cereal virology by covering recent progresses in areas such as: 1) characterization of emerging viruses, 2) analyses of genetic and biological diversities within particular viruses, 3) development of experimental systems applicable to cereal viruses, 4) elucidation of the molecular interactions among viruses, vector organisms, and host plants, 5) identification of traits and genes linked to virus resistance in cereal crops, 6) development of novel genetic approaches for virus resistance, and 7) assessment of epidemiological factors affecting the incidences of cereal virus diseases. Synergistic integration of ideas from such areas under this research topic should help to formulate practical alternatives to the current management options for virus diseases in cereal crops.
Download or read book Advances in Agrochemicals written by Aaron D. Gross and published by ACS Symposium. This book was released on 2018-11-08 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pest management often depends on the use of chemical insecticides that affect important physiological and pharmacological processes in arthropods. The development of chemical insecticides has primarily attacked the arthropod nervous system by targeting and disrupting the function of ligand-gated or voltage-gated ion channels. The use of broad classes of synthetic chemistries with common modes of action, along with the widespread, and sometimes improper, use of chemical insecticides has resulted in the urgent need to find new chemistry and novel or underutilized targets, such as G-protein-coupled receptors (GPCRs) for screening, discovery, and development of novel agrochemicals. This book features contributions from the most highly regarded insecticide scientists in the world. It offers chapters that describe investigations on GPCR's that document the substantial progress that has been made recently in understanding the mechanisms of ligand interactions at the receptors, the downstream cascades, and the exciting promise that this large class of receptors has as targets for new agrochemical products. Multiple experts focus on the latest developments on characterization of their molecular pharmacology, on dopamine-specific GPCRs, and on the breadth of various GPCRs as future targets.
