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.

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.]

Download or read book Voltage Gated Sodium Channels written by Peter C. Ruben and published by Springer Science & Business Media. This book was released on 2014-04-15 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: A number of techniques to study ion channels have been developed since the electrical basis of excitability was first discovered. Ion channel biophysicists have at their disposal a rich and ever-growing array of instruments and reagents to explore the biophysical and structural basis of sodium channel behavior. Armed with these tools, researchers have made increasingly dramatic discoveries about sodium channels, culminating most recently in crystal structures of voltage-gated sodium channels from bacteria. These structures, along with those from other channels, give unprecedented insight into the structural basis of sodium channel function. This volume of the Handbook of Experimental Pharmacology will explore sodium channels from the perspectives of their biophysical behavior, their structure, the drugs and toxins with which they are known to interact, acquired and inherited diseases that affect sodium channels and the techniques with which their biophysical and structural properties are studied.
Download or read book Interrelationship of Nutrition Growth Development and Insecticide Exposure in the German Cockroach Blattella Germanica L written by Richard Dale Kramer and published by . This book was released on 1987 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Homeostatic processes within insects are affected by various extrinsic factors and are maintained through compensatory and/or inductive responses. A study was conducted to evaluate the interrelationship of two extrinsic factors (nutrition and pesticide exposure), on growth, development, feeding behavior and insecticide susceptibility in German cockroaches, Blattella qermanica (L.). Amount of dietary protein had no effect on susceptibility of male German cockroaches to propoxur and chlorpyrifos. The source of protein produced significant changes in insecticide susceptibility. Laboratory rodent chow increased total body lipids, carbohydrates and uric acid which may have resulted in increased tolerance to these insecticides. Three days of food and/or water deprivation had little effect on chlorpyrifos susceptibility, but susceptibility to propoxur increased under these conditions. Following topical propoxur application, males lost 10% of their body weight in the form of water, but this loss did not result in significant changes in water or food consumption subsequent to treatment. Hydroprene produced morphogenetic changes and increased total body mass in emergent adults. Morphogenetic changes in males occurred in the left and right phallomeres, subgenital plate and styli, precluding copulation and was related to dose and age of nymphal exposure. Total body mass of exposed males increased as much as 53% and of females as much as 47%; this change in body mass was accompanied by changes in water balance, total body carbohydrates, lipids and urates. Orlando normal males exposed to a low dose of hydroprene exhibited a slight increase in susceptibility to propoxur, while susceptibility to chlorpyrifos decreased. The multiresistant HRDC strain exhibited similar responses, except that a high hydroprene dose resulted in their increased tolerance to chlorpyrifos. The compounds A9248 and allopurinol were evaluated as growth inhibitors. The antimicrobial agent, A9248, when formulated as a 4% bait, produced 100% mortality in nonchoice tests; in choice tests, however, 32% survived, and reproduction occurred. Allopurinol 2% bait inhibited the accumulation of uric acid in nymphs, reduced percent survival to between 2 and 7%, and postemergent adult survivors failed to reproduce. Adults fed the bait produced significantly fewer nymphs per female.
