Available in PDF, EPUB and Kindle. Book excerpt: The first half of this book is primarily a systematic survey of the snails, beginning with glossaries, keys for identification to genera and a checklist of species. This is followed by a synopsis of species, with brief notes on ecology, distribution and parasites. Relationships are then described between snails and schistosomes and with other parasites. The book goes on to consider the factors affecting snail populations and possible methods for population control.

Download or read book Biogeography and Ecology of Southern Africa written by Marinus J.A. Werger and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Southern Africa is certainly not a naturally bounded area so that there are several possibilities for delineating it and concepts about its extent. Wellington* discussed the various possibilities for delineation and suggested that one line stands out more clearly and definitely as a physical boundary than any other, namely the South Equatorial Divide, the watershed between the ZaIre, Cuanza and Rufiji Rivers on the one hand and the Z ambezi, Cunene and Rovuma Rivers on the other. This South Equatorial Divide is indeed a major line of separation for some organisms and is also applicable in a certain geographical sense, though it does not possess the slightest significance for many other groups of organisms, ecosystems or geographical and physical features of Africa. The placing of the northern boundary of southern Africa differs in fact strongly per scientific dis cipline and is also influenced by practical considerations regarding the possibilities of scientific work as subordinate to certain political realities and historically grown traditions. This is illustrated, for example, in such works as the Flora of Southern Africa, where the northern boundary of the area is conceived as the northern and eastern political boundaries of South West Africa, South Africa and Swaziland. Botswana, traditionally included in the area covered by the Flora Zambesiaca, thus forms a large wedge in 'Southern Africa'.

Download or read book Biology of Snail Killing Sciomyzidae Flies written by Lloyd Knutson and published by Cambridge University Press. This book was released on 2011-09-29 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written for academic researchers and graduate students in entomology, this is the first comprehensive analysis of Sciomyzid flies. Sciomyzid flies are important as prime candidates for the biological control of snails and slugs that help transmit diseases such as schistosomiasis or are important agricultural pests. They also serve as a paradigm for the study of the evolution of feeding behavior in predatory insects. Starting with analyses of malacophagy in general and then in Diptera specifically, all important aspects of the Sciomyzidae are discussed, including behavior, ecology, life cycles, morphology, and identification. New behavioral and morphological classifications and hypotheses are proposed on the basis of unpublished information and a complete analysis of the extensive literature. Also included are keys to adults, larvae and puparia and a checklist of world species, with information on geographical range and the location of type specimens. The accompanying DVD includes Clifford O. Berg's classic film on the biology of Sciomyzidae and biological control of snails.
Download or read book Catalogue of Helminths of Waterfowl Anatidae written by Malcolm Edwin McDonald and published by . This book was released on 1969 with total page 704 pages. Available in PDF, EPUB and Kindle. Book excerpt: This catalogue summarizes the information available on each helminth reported as a parasite of waterfowl ("waterfowl" is used here as a term for the Anatidae only): the names applied to it, its life history, hosts, location in the host, geographical distribution, frequency of record in waterfowl, and importance as a cause of disease. This paper is incomplete in certain respects; no general catalogue can include all the pertinent literature of the world and new information is constantly being added. About 120 papers each year record data and describe about 15 new species of helminths in waterfowl.

Download or read book Parasiticide Screening written by Alan A. Marchiondo and published by Academic Press. This book was released on 2019-06-08 with total page 724 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parasiticide Discovery: In Vitro and In Vivo Tests with Relevant Parasite Rearing and Host Infection/Infestation Methods, Volume Two presents valuable screening methods that have led to the discovery of the majority of parasiticides commercialized in the animal health industry. As much of the knowledge of parasiticide discovery methods is being lost in the animal health industry as seasoned parasitologists retire, this book serves to preserve valuable methods that have led to the discovery of the majority of parasiticides commercialized in animal health, also giving insights into the in vitro and in vivo methods used to identify the parasiticide activity of compounds. - Addresses current issues of resistance, along with combination uses for resistant parasites - Presents useful, authoritative information (chemical, pharmaceutical, clinical, etc.) for the pyrantel family of compounds - Includes a discussion on screening methods in combination therapies - Provides cutting-edge material for an evolving area of scientific discussion - Includes in vitro and in vivo screens and parasite maintenance and culture methods

Download or read book Controlled Release Pesticides Formulations written by Nathan F. Cardarelli and published by CRC Press. This book was released on 2018-01-17 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main goal of this book is to present a summary of the state of the art historical background. Conventional chemical pest control methods are mentioned only as a means of comparison to controlled release. Research endeavour with biological weapons, potential usage of such controls, and the few instances of success are likewise brought into focus with the same motive. Formulations and methods or preparing controlled release pesticides are discussed in some detail as concerns the antifouling and molluscicide areas, where the compounding methodology has been well developed. The mathematical basis of controlled release has been developed to an extent and is presented in an abbreviated form.

Download or read book CRC Handbook of the Zoology of Amphistomes written by Otto Sey and published by CRC Press. This book was released on 2019-01-15 with total page 824 pages. Available in PDF, EPUB and Kindle. Book excerpt: Handbook of the Zoology of Amphistomes provides a comprehensive survey on the morphology, ecology, systematics, and zoogeography of amphistomes, which are a group of digenetic trematodes parasitic in vertebrates. The handbook features the special morphological characteristics of amphistomes, including the structure and types of muscular organs; a short diagnosis for each species (when possible), as well as a line drawing of each adult fluke; a zoogeographical analysis, including the host-parasite coevolution, distributional patterns, and characterization of faunas within the zoogeographical realm; and a possible evolutionary scenario based on holomorphological characteristics. Parasitologists, helminthologists, zoologists, and biologists working with ecological associations will find this book an essential reference source for their work with amphistomes.
