Available in PDF, EPUB and Kindle. Book excerpt: Wheat is considered an essential part of food from ordinary households to national and international families. Important pests of wheat are aphids, Rhopalosiphum padi (bird cherry-oat aphid), Schizaphis graminum (greenbug), R. maidis (corn leaf aphid), Metopoliphium dirhodum (rose grass aphid), Sitobion avenae (English grain aphid), Diuraphis noxis (Russian wheat aphid), Stink Bugs, Armyworms, Cut worms and Stalk borrers (various species), Cereal leaf beetle (Oulema melanopa), thrips (various species), Hessian fly (Mayetiola destructor ) wheat stem maggot (Meromyze Americana), Sawfly (Cephus cinctus, Wireworms (various species), Slugs, snails, grasshoppers and crickets (various species), Mites (various species).Hover fly grubs, ground beetle, among all of these insects aphid.. Biological controls require introducing predator or parasite species to kill the pest. These bio-control agents mainly comprising lady bird beetles (Coccinellids) are described in this book for efficient and ecofriendly management approach of aphids.

Book excerpt: Their natural enemies largely determine the population size and dynamic behavior of many plant-eating insects. Any reduction in enemy number can result in an insect outbreak. Applied biological control is thus one strategy for restoring functional biodiversity in many agroecosystems. Predators and Parasitoids addresses the role of natural enemies i
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 Evaluating the Non Consumptive Effects of Insect Predators on Aphids and Aphid Borne Virus Transmission written by Benjamin Walter Lee and published by . This book was released on 2021 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predators exhibit "consumptive effects" (CEs) by capturing and consuming prey, while exhibiting "non-consumptive effects" (NCEs) on prey physiology and behavior through failed attacks that influence their perception of risk in the environment. Predatory insects are widely used to control agricultural pests, including insect vectors of pathogens, though their role in affecting pathogen transmission has been poorly understood. This dissertation evaluates a range of predation effects on aphid vectors and their transmission of Pea enation mosaic virus (PEMV), an economically damaging aphid-borne pathogen of legumes grown in the Pacific Northwest USA. The first chapter discusses difficulties in predicting vector-borne virus transmission using mathematical models, as vectors' interactions with other species can unpredictably affect rates of pathogen transmission. The second chapter documents a field study evaluating predator CEs and NCEs on aphid vector abundance, movement, and feeding behavior and how these effects contribute to aphids' ability to transmit PEMV. Analysis using structural equation modeling revealed predators indirectly increased PEMV prevalence by inducing aphids to disperse to new hosts and feed upon parts of the host plant on which pathogen transmission is greater. The third chapter details several greenhouse experiments examining how vector responses to signals of predation risk affect transmission of PEMV. I found that chemical cues left by predators or alarm pheromones released by conspecifics reduced aphids' ability to acquire and transmit PEMV but had no effect on their fecundity or nutrition. The final chapter describes a field study examining how diverse predator communities affect aphids and PEMV transmission. When multiple predator species feed on aphid vectors, their effects on aphid abundance can be synergistic or antagonistic, though the impacts of predator diversity on aphid behavior and transmission efficiency are unknown. I find that predator diversity enhanced aphid suppression but altered aphid behavior in ways that increased virus transmission, resulting in no net change in PEMV prevalence. This final chapter suggests that the benefits of increasing diversity for pest suppression may not similarly influence disease risk. This dissertation improves our understanding of how insect predators affect plant pathogen transmission and will inform management strategies using natural enemies to combat plant pathogens.

Download or read book Aphid Biodiversity under Environmental Change written by Pavel Kindlmann and published by Springer Science & Business Media. This book was released on 2010-07-01 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the results of recent research on aphid population dynamics and ecology relevant to current environmental changes resulting from global wa- ing. It incorporates a selection of the contributions presented at the International Symposium on Aphids in Fremantle, Australia, in October 2005, plus some ad- tional invited chapters. The objective was to incorporate the major issues in the ?eld and simultaneously create a closely interrelated and integrated volume. The ?rst chapter sets the scene. Kindlmann and Dixon present a critical review of existing models of aphid population dynamics, examine the biological assumptions that are incorporated in the models and present one of the latest models of aphid metapopulation dynamics. They conclude that natural enemies are unlikely to affect aphid population dynamics late in a season, but in some years may have an effect very early in the season, when aphid colonies are still small and predators might be able to reduce the numbers of colonies. The question, whether aphids will move to different locations, adapt to the change in conditions in their current habitat or go extinct is discussed by Ameixa. She concludes that the distributions of aphids are most likely to change, with the distribution of each species moving globally as their preferred habitat moves in response to changes in the climate, which may be more dif?cult than in the past because of habitat fragmentation and habitat loss.
