This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cotton aphid, Aphis gossypii Glover (Hemiptera: Aphididae), is a highly polyphagous pest that inflicts serious damage to a broad range of agricultural, horticultural and greenhouse crops. In Australia, A. gossypii is a significant pest of cotton and is difficult to control with insecticides because of its high propensity to develop resistance. Neonicotinoids are among the most effective insecticides used to control A. gossypii but the most recent detection of resistance threatens their longevity. Consequently, I aimed to restore neonicotinoid efficacy against A. gossypii through elucidation of underlying resistance mechanism(s). Bioassay was used to measure thiamethoxam (neonicotinoid) response in three field strains collected from commercial cotton. A second trial investigated the use of phorate (an organophosphate) as an alternative pre-germination treatment to thiamethoxam. PCR-Sequencing was employed to identify if mutation R81T known to confer resistance to neonicotinoid compounds was present in Australian A. gossypii. High-throughput sequencing of the A. gossypii transcriptome found differences in gene expression associated wit hthiamethoxam resistance. Two transcripts involved in the detoxification of xenobiotics (putatively annotated as cytochrome p450 gene 6K1-like) were found differentially expressed between resistant and suceptible strains. Transcript expression was further validated by qRT-PCR and showed a similar tendency in upregulation of expression. As such I identified this gene as the strongest candidate for thiamethoxam resistant A. gossypii. This study has generated a comprehensive transcriptome resource for A. gossypii that has characterised the expression of numerous important transcripts encoding proteins involved in insecticide resistance. Consequently, my study will contribute to future research relating to molecular characterization of insecticide resistance mechanisms in A. gossypii and other insect pests.

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 Integration of Insect Resistant Genetically Modified Crops within IPM Programs written by Jörg Romeis and published by Springer Science & Business Media. This book was released on 2008-07-01 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insect pests remain one of the main constraints to food and fiber production worldwide despite farmers deploying a range of techniques to protect their crops. Modern pest control is guided by the principles of integrated pest management (IPM) with pest resistant germplasm being an important part of the foundation. Since 1996, when the first genetically modified (GM) insect-resistant maize variety was commercialized in the USA, the area planted to insect-resistant GM varieties has grown dramatically, representing the fastest adoption rate of any agricultural technology in human history. The goal of our book is to provide an overview on the role insect-resistant GM plants play in different crop systems worldwide. We hope that the book will contribute to a more rational debate about the role GM crops can play in IPM for food and fiber production.

Download or read book Insect Nicotinic Acetylcholine Receptors written by Steeve Hervé Thany and published by Springer Science & Business Media. This book was released on 2011-01-11 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to summarize our understanding on the insect nicotinic acetylcholine receptors. This area of research received great impetus from the identification of the first subunit sequences to be used as neonicotinoid insecticide target sites. Although a book of this nature can provide the details only of commonly published results, it is hoped that it may provide a useful guide to the newcomer to the field as well as to point out some of the future challenges. For example, we need to determine the precise subunit nomenclature of insect nicotinic receptors. This nomenclature varies amongst species and this led to some of the early confusion that persists. We need to be precise in identifying the subunit composition of native insect nicotinic receptor subtypes, their functional properties and physiological roles.

Download or read book Biochemical Sites of Insecticide Action and Resistance written by Isaac Ishaaya and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years many of the conventional methods of insect control by broad spectrum synthetic chemicals have come under scrutiny because of their unde sirable effects on human health and the environment. In addition, some classes of pesticide chemistry, which generated resistance problems and severely affected the environment, are no longer used. It is against this background that the authors of this book present up-to-date findings-relating to biochemical sites that can serve as targets for developing insecticides with selective prop erties, and as the basis for the elucidation of resistance mechanisms and countermeasures. The book consists of eight chapters relating to biochemical targets for insec ticide action and seven chapters relating to biochemical modes of resistance and countermeasures. The authors of the chapters are world leaders in pesti cide chemistry, biochemical modes of action and mechanisms of resistance. Biochemical sites such as chitin formation, juvenile hormone and ecdysone receptors, acetylcholine and GABA receptors, ion channels, and neuropeptides are potential targets for insecticide action. The progress made in recent years in molecular biology (presented in depth in this volume) has led to the iden tification of genes that confer mechanisms of resistance, such as increased detoxification, decreased penetration and insensitive target sites. A combina tion of factors can lead to potentiation of the resistance level. Classifications of these mechanisms are termed gene amplification, changes in structural genes, and modification of gene expression.
