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 Biology and Management of the German Cockroach written by Changlu Wang and published by CSIRO PUBLISHING. This book was released on 2021-05-03 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a species, the German cockroach is one of the most widespread indoor urban pests worldwide. While numerous products have been developed to control their spread, German cockroaches continue to contaminate food, transmit disease and cause significant, long-term economic expense to homes, restaurants, hospitals and more. Biology and Management of the German Cockroach summarises the many advances in management technology, products, delivery systems, and basic and applied research over the past 25 years. Leading researchers explain why the German cockroach is a medically important pest and how its microbiome can provide new insights on cockroach physiology and potential novel targets for control. The authors also address the research from a practical standpoint, detailing why baits have replaced sprays as the primary method of control and how population genetic studies allow for better understanding of cockroach dispersal and population structure. Leading experts on integrated pest management (IPM) explore how studies on German cockroach control programs demonstrate the value and feasibility of IPM in urban environments. This book provides the reader with a comprehensive understanding of the German cockroach and will be a valuable reference for researchers, graduate students, pest management professionals, health workers and government agencies dealing with urban pests and pesticides.
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 Pesticide Resistance in Arthropods written by Richard Roush and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bruce E. Tabashnik and Richard T. Roush Pesticide resistance is an increasingly urgent worldwide problem. Resistance to one or more pesticides has been documented in more than 440 species of insects and mites. Resistance in vectors of human dise8se, particularly malaria-transmit ting mosquitoes, is a serious threat to public health in many nations. Agricultural productivity is jeopardized because of widespread resistance in crop and livestock pests. Serious resistance problems are also evident in pests of the urban environ ment, most notably cockroaches. Better understanding of pesticide resistance is needed to devise techniques for managing resistance (Le. , slowing, preventing, or reversing development of resistance in pests and promoting it in beneficial natural enemies). At the same time, resistance is a dramatic example of evolution. Knowledge of resistance can thus provide fundamental insights into evolution, genetics, physiology, and ecology. Resistance management can help to reduce the harmful effects of pesticides by decreasing rates of pesticide use and prolonging the efficacy of environmentally safe pesticides. In response to resistance problems, the concentration or frequency of pesticide applications is often increased. Effective resistance management would reduce this type of increased pesticide use. Improved monitoring of resis tance would also decrease the number of ineffective pesticide applications that are made when a resistance problem exists but has not been diagnosed. Resistance often leads to replacement of one pesticide with another that is more expensive and less compatible with alternative controls.

Available in PDF, EPUB and Kindle. Book excerpt: The second half of the 20th century and the beginning of the 21st century witnessed important changes in ecology, climate and human behaviour that favoured the development of urban pests. Most alarmingly, urban planners now face the dramatic expansion of urban sprawl, in which city suburbs are growing into the natural habitats of ticks, rodents and other pests. Also, many city managers now erroneously assume that pest-borne diseases are relics of the past. All these changes make timely a new analysis of the direct and indirect effects of present-day urban pests on health. Such an analysis should lead to the development of strategies to manage them and reduce the risk of exposure. To this end, WHO invited international experts in various fields - pests, pest-related diseases and pest management - to provide evidence on which to base policies. These experts identified the public health risk posed by various pests and appropriate measures to prevent and control them. This book presents their conclusions and formulates policy options for all levels of decision-making to manage pests and pest-related diseases in the future. [Ed.]

C. Lee and published by . This book was released on 1998 with total page 2 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological parameters of an insecticide resistance strain (ML) of the German cockroach, Blatella germanica (L.) which was reared either in groups or alone, was compared with those of a susceptible strain (ICI). Both ICI and ML strains showed significantly longer nymphal development period when reared alone, than when reared in groups. Ml strains also demonstrated significantly longer preoviposition and incubation periods, but lower number of offsprings per ootheca when compared with those of the ICI strain in the absence of insecticide selection. The implication of this study with regards to development of insecticide resistance in the German cockroach is discussed. [Authors' abstract].

Thus, behavioural resistance might play a role in cockroach control under field condition. [Authors' abstract].
