This book was released on 2017-10-13 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Report on Investigations of the Pink, Bollworm of Cotton in Mexico Bolls and squares were used, but the squares were found more satisfactory. The food with the young larvae was placed in vials plugged with cotton. The pieces of bolls would become discolored, decomposed, and unsuitable for food in one or two days, while a square would remain in good condition several days and the larva could be examined daily with less disturbance. Wire cages were also used over small potted plants and cotton plants in the experimental plat to check the laboratory results. The pupae were removed to glass vials with a piece of damp cotton in the bottom to provide the necessary humidity.

Download or read book Gene Drives on the Horizon written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2016-08-28 with total page 231 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research on gene drive systems is rapidly advancing. Many proposed applications of gene drive research aim to solve environmental and public health challenges, including the reduction of poverty and the burden of vector-borne diseases, such as malaria and dengue, which disproportionately impact low and middle income countries. However, due to their intrinsic qualities of rapid spread and irreversibility, gene drive systems raise many questions with respect to their safety relative to public and environmental health. Because gene drive systems are designed to alter the environments we share in ways that will be hard to anticipate and impossible to completely roll back, questions about the ethics surrounding use of this research are complex and will require very careful exploration. Gene Drives on the Horizon outlines the state of knowledge relative to the science, ethics, public engagement, and risk assessment as they pertain to research directions of gene drive systems and governance of the research process. This report offers principles for responsible practices of gene drive research and related applications for use by investigators, their institutions, the research funders, and regulators.
Download or read book The Book of Unconformities written by Hugh Raffles and published by Verse Chorus Press. This book was released on 2022-04-18 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: From the author of lnsectopedia, a powerful exploration of loss, grief, endurance, and the absences that permeate the present. Unconformities are gaps in the geological record, physical evidence of breaks in time. For Hugh Raffles, these holes in history are also fissures in feeling, knowledge, memory, and understanding. In this endlessly inventive, riveting book, Raffles enters these gaps, drawing together threads of geology, history, literature, philosophy, and ethnography to trace the intimate connections between personal loss and world historical events, and to reveal the force of absence at the core of contemporary life. Through deeply researched explorations of Neolithic stone circles, Icelandic lava, mica from a Nazi concentration camp, petrified whale blubber in Svalbard, the marble prized by Manhattan's Lenape, and a huge Greenlandic meteorite that arrived in New York City along with six Inuit adventurers in 1897, Raffles shows how unconformities unceasingly incite human imagination and investigation yet refuse to conform, heal, or disappear. A journey across eons and continents, The Book of Unconformities is also a journey through stone: this most solid, ancient, and enigmatic of materials, it turns out, is as lively, capricious, willful, and indifferent as time itself.
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.

Download or read book Classical Biological Control of Bemisia tabaci in the United States A Review of Interagency Research and Implementation written by Juli Gould and published by Springer Science & Business Media. This book was released on 2008-03-01 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews interagency research and development of classical (importation) biological control of Bemisia tabaci (biotype B) conducted in the USA from 1992- 2002. The successful discovery, evaluation, release, and establishment of at least five exotic B. tabaci natural enemies in rapid response to the devastating infestations in the USA represents a landmark in interagency cooperation and coordination of multiple disciplines. The review covers all key aspects of the classical biocontrol program, beginning with foreign exploration and quarantine culture, through dev- opment of mass rearing methodology, laboratory and field evaluation for efficacy, to field releases, integration with other management approaches, and monitoring for establishment and potential non-target impacts. The importance of morphological and molecular taxonomy to the success of the program is also emphasized. The book’s contributors include 28 USDA, state department of agriculture, and univ- sity scientists who participated in various aspects of the project. Bemisia tabaci continues to be a pest of major concern in many parts of the world, especially since the recent spread of the Q biotype, so the publication of a review of the biological control program for the B biotype is especially timely. We anticipate that our review of the natural enemies that were evaluated and which have established in the USA will benefit researchers and IPM practitioners in other nations affected by B. tabaci.

Book excerpt: A New York Times Notable Book A stunningly original exploration of the ties that bind us to the beautiful, ancient, astoundingly accomplished, largely unknown, and unfathomably different species with whom we share the world. For as long as humans have existed, insects have been our constant companions. Yet we hardly know them, not even the ones we’re closest to: those that eat our food, share our beds, and live in our homes. Organizing his book alphabetically, Hugh Raffles weaves together brief vignettes, meditations, and extended essays, taking the reader on a mesmerizing exploration of history and science, anthropology and travel, economics, philosophy, and popular culture. Insectopedia shows us how insects have triggered our obsessions, stirred our passions, and beguiled our imaginations.
