Available in PDF, EPUB and Kindle. Book excerpt: The great majority of the contributions to be found in this volume result from oral presentations given at a symposium during the XVIII International Congress of Entomology entitled Mechanisms of Aphid-Plant Genotype Interactions, which was held in Vancouver, Canada in July, 1988. Aphids represent a vast and diverse assemblage of insects. Among these are many of great economic importance by virtue of their detrimental effects to important crop or ornamental plants. Even those aphids having little or no economic impact, or that cause no damage to their hosts except nutrient removal, may yet be of great theoretical interest in that their often intimate association with their hosts provides excellent systems for the study of the evolution of adaptation. Other factors, such as environmental influences, and associations with pathogenic, saprophytic, or symbiotic microorganisms, may play an influential role in modifying the ultimate outcome of aphid-plant interactions. Substantive future progress towards the elucidation of these processes can only be expected if much greater understanding is obtained of the interactions of all the organisms involved in the plant based community.
Download or read book Aphids as Virus Vectors written by Kerry F. Harris and published by Elsevier. This book was released on 2014-05-10 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aphids as Virus Vectors focuses on aphids as vectors of plant viruses and the fundamentals of their relationship with virus and host. The mouthparts and feeding mechanism of aphids are discussed, along with aphid penetration of plant tissues and the transmission mechanisms of aphids as virus vectors. The intrinsic properties and taxonomy of aphid-borne viruses are also examined. Comprised of 22 chapters, this book begins with an overview of the importance of aphids as vectors, their biology, and the properties of the viruses they transmit. These introductory chapters prepare the reader for later ones on aphid-virus-plant interactions. The next section deals with transmission mechanisms, with emphasis on several novel alternatives to many of the traditionally held concepts of how aphids transmit viruses. Accessory factors in non-persistent virus transmission are considered. Subsequent chapters focus on technological advances in aphid-virus research, including the use of aphid cell culturing, radioisotope methodology, membrane feeding, and electrical measurement systems. The most promising frontiers in epidemiological and control-oriented research are discussed in the last two sections. This monograph will be a useful resource for researchers from such varied sciences as entomology, plant science, and virology, as well as for graduate students taking entomology and plant pathology courses on insects in relation to plant diseases.

Available in PDF, EPUB and Kindle. Book excerpt: Most people know of aphids as garden pests, infesting the soft green tissues of plants in vast numbers and killing them by sucking out the sap. Indeed, among the 4000 or so known species of aphids about 250 are pests, and in temperate regions several are economically important agricultural pests that damage crops directly during feeding or act as v
Download or read book Aphids as Plant Pests From Biology to Green Control Technology written by Julian Chen and published by Frontiers Media SA. This book was released on 2024-01-19 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aphids (Hemiptera: Aphidoidea) are one of the most important and destructive agriculture pests causing serious economic losses by both nutrient robbing and transmitting plant viruses. 100 species of Aphididae have exploited the agricultural environment successfully to the extent that they are of significant economic importance, among them 15 aphid species of most agricultural importance. Aphids are piecing-sucking insect pests with the mouthparts (stylets) to penetrate plant cells to feed phloem sap from sieve elements. The feeding process of aphids is similar to pathogen infestation, and plenty of evidence demonstrate that the interplay between aphid and host plants follows the pathogen-plant Zigzag model. During the process of probing and feeding, aphids, like plant pathogens, secreted some salivary proteins as effectors (or elicitors) into their host plants cell intercellularly and intracellularly to mediate aphid-plant interactions, such as eliciting or suppressing plant defense responses. Aphids also vector plant viruses, and the relationship between each organismal pair affects the overall outcome of this biological interaction. Aphids contained endosymbionts, and the symbionts influence interaction between the aphids and their host plants and between aphids and their natural enemies, further impacting this network of biological interactions. Advances in understanding aphids biology, and these interactions at the physiological, molecular, and ecological levels will provide fundamental knowledge, and develop novel green control strategies for insect pests as well as vector pathogens.

Book excerpt: Aphids are important herbivores and important pest of many field and forest crops. They have specialized long and flexible stylets which are adapted to feeding on phloem sap. To establish successful feeding on host plant, they need to counter a range of both physical and chemical defenses. The defenses employed by plants can have direct effect on the aphid species through difficulty in establishing successful feeding due to the presence of trichomes, thick cell wall, etc. or effect on their biology with lethal consequences in extreme cases (direct defenses). In contrast to this, plants can attract natural enemies of aphids through the release of volatile compounds (the so-called ,Äúcry or call for help,Äù) (indirect defense). The information on different defense strategies employed by plants can be utilized to enhance the level of resistance (R) to develop sustainable pest management strategies.

Download or read book Aphids as Crop Pests 2nd Edition written by Helmut F van Emden and published by CABI. This book was released on 2017-08-23 with total page 716 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aphids are among the major global pest groups, causing serious economic damage to many food and commodity crops in most parts of the world. This revision and update of the well-received first edition published ten years ago reflects the expansion of research in genomics, endosymbionts and semiochemicals, as well as the shift from control of aphids with insecticides to a more integrated approach imposed by increasing resistance in the aphids and government restrictions on pesticides. The book remains a comprehensive and up-to-date reference work on the biology of aphids, the various methods of controlling them and the progress of integrated pest management as illustrated by ten case histories.

Download or read book Regulatory Mechanisms in Insect Feeding written by Reg F. Chapman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: The only book to deal comprehensively with insect feeding was published by C. T. Brues in 1946. His Insect Dietary was an account of insect feeding habits. Since that time there has been a revolution in biology, and almost all aspects of our understanding of insect feeding have expanded to an extent and into areas that would have been unthinkable in Brues' day. Yet, our book does not replace Insect Dietary but, instead, complements it, because our aim is to bring together information on the mechanisms by which food quality and quantity are regulated. We deliberately focus attention on the feeding process; to include food-finding would have required a much larger book and would have moved the focus away from more proximate mechanisms. This book is dedicated to the late Vincent G. Dethier. As a pioneer in studying the physiological basis of animal behavior, he focused on regulation of feeding in flies and caterpillars. His work on the blowfly, together with that by his many students and co-workers, still provides the most completely described mechanism of insect feeding. The citation of his work in almost every chapter in this book illustrates the importance of his findings and ideas to our current understanding of regulation of insect feeding. The authors in this book provide many innovative and stimulating ideas typifying Dethier's approach to the study of feeding be havior.
