Lee and published by . This book was released on 1998 with total page 2 pages. Available in PDF, EPUB and Kindle. Book excerpt: Esterase involvement was studied further using a modified microplate bioassay technique using - and B-naphthyl acetate as model substrates. the ML strain showed significant increase in esterase activity when compared to that of the susceptibel strain. The resistance gene frequency of the ML strain was estimated as 0.62 +- ).10 using the Dardy-Weinberg equilibrium equation. The implication of this finding with regards to resistance management options is discussed. [Author's abstract].
Download or read book Semiochemical based Food foraging in German Cockroaches Blattella Germanica L Dictyoptera Blattellidae written by Nooshin Karimifar and published by . This book was released on 2009 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: In two-choice, still-air arena olfactometer experiments, Porapak-Q headspace volatile extract of peanut butter and solvent extract of beer were shown to attract males of the German cockroach, Blattella germanica (L.) (Dictyoptera: Blattellidae). Coupled gas chromatographic-electroantennographic detection (GC-EAD) and GC-mass spectrometric (MS) analyses of these attractive extracts, or fractions thereof, and of synthetic standards, revealed many candidate semiochemicals. Elaborate olfactometer experiments determined that 1-hexanol from peanut butter, and ethanol and 2,3-dihydro-3,5-dihydroxy-6-methyl-4(H)-pyran-4-one (DDMP) from beer, are the key semiochemicals of these food sources. 1-Hexanol is a well known headspace volatile of decomposing lipids, ethanol conveys food fermentation, and DDMP with a caramel-type flavor has been found in many types of (heated) food. By responding to these rather general food-derived compounds, the omnivorous German cockroaches appear to exploit semiochemicals that indicate the presence of various food types, such as lipids and carbohydrates.
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.
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.
Download or read book Biology of Termites a Modern Synthesis written by David Edward Bignell and published by Springer Science & Business Media. This book was released on 2010-10-20 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biology of Termites, a Modern Synthesis brings together the major advances in termite biology, phylogenetics, social evolution and biogeography. In this new volume, David Bignell, Yves Roisin and Nathan Lo have brought together leading experts on termite taxonomy, behaviour, genetics, caste differentiation, physiology, microbiology, mound architecture, biogeography and control. Very strong evolutionary and developmental themes run through the individual chapters, fed by new data streams from molecular sequencing, and for the first time it is possible to compare the social organisation of termites with that of the social Hymenoptera, focusing on caste determination, population genetics, cooperative behaviour, nest hygiene and symbioses with microorganisms. New chapters have been added on termite pheromones, termites as pests of agriculture and on destructive invasive species.
