Book excerpt: Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Book excerpt: Excerpt from House-Flies and How They Spread Disease The discovery of the serious role which the house fly may play under certain conditions, was hardly less astonishing than the revelation of our profound ignorance of its life-history, habits and bionomics generally. In this respect it afforded another example of a not infrequent occurrence in biology, namely, the passing over of the commonplace in the search for the unique and rare. Zoological literature is replete with minute descriptions of creatures which few have seen, or ever will see, and which have not.

Book excerpt: Excerpt from book: II THE NATURAL ENEMIES OF THE TYPHOID AS with every other living creature, nature makes its own effort to limit the abundance of the fly under consideration, and the extraordinary facility for multiplication which the fly possesses is in turn the result of the instinctive effort of the organism to maintain its status in spite of the numerous enemies which confront it. The natural enemies of the house fly begin with the acme of the vertebrate series (man himself) and end with the lower forms of plant life, and we will begin our consideration of these agencies with the latter forms. Fungous Diseases In the autumn it is a matter of common observation that many flies in houses and on the windows become sluggish and frequently die in such positions. The sluggishness may be accounted for in a measure by the advent of cold weather, and as a matter of fact cold weather frequently drives indoors other species of flies of a more sluggish nature than the house fly. In this way the so-called cluster fly (Pollenia rudis), a rather sluggish species, which will be referred to in another chapter, is frequently found in houses in the autumn. But the principal cause of the sluggishness on the part of the house fly in the autumn is the attack of fungous diseases. Sometimes they are found to be dead without any evidence of the cause of death. Later they are seen to be surrounded by a white fungus growth. There is a group of fungi belonging to the En- tomophthoreae, many of which are parasitic upon insects. There are several genera in this group, but the only one which need be considered at present is the genus Empusa. The fungi of this group have been studied by Dr. Roland Thaxter of Harvard University, and it is from his writings that the following statements have been drawn.

Available in PDF, EPUB and Kindle. Book excerpt: Developed as an introduction to new molecular genetic techniques, Insect Molecular Genetics also provides literature, terminology, and additional sources of information to students, researchers, and professional entomologists. Although most molecular genetics studies have employed Drosophila, this book applies the same techniques to other insects, including pest insects of economic importance. As a text, as a reference, as a primer, and as a review of a vast and growing literature, Insect Molecular Genetics is a valuable addition to the libraries of entomologists, geneticists, and molecular biologists. Features offered by this unique reference source: Detailed illustrations Suggested readings at the end of each chapter Glossary of molecular genetic terms

Download or read book Flies and Disease written by Bernard Greenberg and published by Princeton University Press. This book was released on 2019-01-29 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: This second volume of Flies and Disease spans the recorded history of synanthropic flies, from earliest Sumerian writings to contemporary research on their biology and involvement in the transmission of disease agents. Geographically, its coverage is worldwide. Biologically, it provides an in-depth view of the community in the fly and the fly in the community. The exhaustive evaluation of fly involvement in more than sixty human and animal diseases is drawn against a background that gives careful balance to other modes of dissemination. The opening chapter is a survey of attitudes toward flies through recorded history. The second chapter deals with the life history, breeding, distribution, dispersal, and overwintering habits of common synanthropic flies. Chapter 3 looks at the fly as a host and examines its micro-ecology from the viewpoint of the microbe intent on colonizing the fly. The final two chapters examine the evidence for the specific involvement of flies in human and animal diseases. The result is the most complete portrait ever drawn of these ancient pests and a rational basis for new programs of research. This book should prove invaluable to the public health worker, epidemiologist, medical entomologist, microbiologist, and parasitologist. Together with Volume I, it is a monumental work on the complex subject of flics and disease and will remain the definitive work for years to come. Bernard Greenberg is Professor of Biological Sciences at the University of Illinois, Chicago Circle. Originally published in 1973. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
Download or read book Life Cycle and Development of Diptera written by Muhammad Sarwar and published by BoD – Books on Demand. This book was released on 2020-09-23 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diptera, or true flies, are of considerable economic importance, as these flies have a valuable role as scavengers, parasitoids and predators of other insects, pollinators, food for predators, bio-indicators of water quality, and tools for scientific research. In nine chapters, this book examines various aspects of flies of the order Diptera as well as some types of mosquitos and midges. Topics covered include taxonomy, phylogeny, life cycle, feeding habits, population control strategies, and more. A unique chapter on forensic entomology is particularly interesting. Beautifully illustrated and expertly researched, this volume will appeal to entomologists, biologists, and naturalists.
