This book was released on 1998 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies on resistance of the horn fly, Haematobia irritans irritans (L.), to insecticides were conducted in Louisiana from 1989 to 1998. These studies included monitoring resistance and resistance dynamics under different strategies of insecticide use, monitoring the efficacy of insecticide products, establishing a relationship between bioassay findings and product efficacy, and evaluation of a new insecticide class. In four years (1989-1992), efficacy of 20% diazinon-impregnated ear tags used yearly was reduced from greater than twenty to just one week of control, and tag failure was observed with resistance ratios (RR) from 1.8 to 5.7. Diazinon resistance developed more slowly and to a lower magnitude than that reported for pyrethroids. A strong correlation was found between RR and the frequency of flies (RF) surviving a 1.72 ug/cm2 discriminating concentration of diazinon. A high risk of diazinon tag failure was associated with a 5% RF in pre-season bioassays. Resistance among several organophosphate (OP) insecticides including fenthion, ethion, pirimiphos-methyl, and tetrachlorvinphos was observed following the development of resistance to diazinon. Esterese activity was significantly higher in OP-resistant flies than in susceptible flies from both laboratory colony and field population. From 1991 to 1997, the yearly rotation of lambda-cyhalothrin + piperonyl butoxide and pirimiphos-methyl ear tags was evaluated for control of pyrethroid-resistant horn flies in two locations. Control efficacy was reduced to a maximum of two and seven weeds for the synergized pyrethroid and OP tags in their last year of use, respectively. The rotation did not improve pyrethroid efficacy or prevent further development of resistance to the pyrethroid or the OP. During 1996 and 1997, the efficacy of experimental chlorfenapyr ear tags for horn fly control was evaluated under field conditions at one location, and the susceptibility of flies to chlorfenapyr was measured at seven locations in 1997. Ear tags containing either 30 or 40% chlorfenapyr were effective for fly control, and the number of weeks with >90%fly reduction ranged from eight to eighteen. All field populations of horn flies, including those resistant to pyrethroids and OPs, were more susceptible to chlorfenapyr than were from a reference susceptible colony.

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: Based on a symposium sponsored by the Board on Agriculture, this comprehensive book explores the problem of pesticide resistance; suggests new approaches to monitor, control, or prevent resistance; and identifies the changes in public policy necessary to protect crops and human health from the ravages of pests. The volume synthesizes the most recent information from a wide range of disciplines, including entomology, genetics, plant pathology, biochemistry, economics, and public policy. It also suggests research avenues that would indicate how to counter future problems. A glossary provides the reader with additional guidance.

Available in PDF, EPUB and Kindle. Book excerpt: This book contains 20 chapters, which are divided into 5 sections. Section 1 covers different aspects of insecticide resistance of selected economically important plant insect pests, whereas section 2 includes chapters about the importance, development and insecticide resistance management in controlling malaria vectors. Section 3 is dedicated to some general questions in insecticide resistance, while the main topic of section 4 is biochemical approaches of insecticide resistance mechanisms. Section 5 covers ecologically acceptable approaches for overcoming insecticide resistance, such are the use of mycoinsecticides, and understanding the role of some plant chemical compounds, which are important in interactions between plants, their pests and biological control agents.

Download or read book Insect Resistance Management written by David W. Onstad and published by Academic Press. This book was released on 2007-12-05 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects, mites, and ticks have a long history of evolving resistance to pesticides, host-plant resistance, crop rotation, pathogens, and parasitoids. Insect resistance management (IRM) is the scientific approach to preventing or delaying pest evolution and its negative impacts on agriculture, public health, and veterinary issues. This book provides entomologists, pest management practitioners, developers of new technologies, and regulators with information about the many kinds of pest resistance including behavioral and phenological resistance. Abstract concepts and various case studies provide the reader with the biological and economic knowledge required to manage resistance. No other source has the breadth of coverage of this book: genomics to economics, transgenic insecticidal crops, insecticides, and other pest management tactics such as crop rotation. Dr. David W. Onstad and a team of experts illustrate how IRM becomes efficient, effective and socially acceptable when local, social and economic aspects of the system are considered. Historical lessons are highlighted with new perspectives emphasized, so that future research and management may be informed by past experience, but not constrained by it. * First book in 15 years to provide the history and explore aspects of a variety of stakeholders * Contributors include experts on ecological aspects of IRM, molecular and population genetics, economics, and IRM social issues * Biochemistry and molecular genetics of insecticides presented with an mphasis on past 15 years of research including Cry proteins in transgenic crops * Encourages scientists and stakeholders to implement and coordinate strategies based on local social conditions

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.]
