Book excerpt: Excerpt from Elementary Textbook of Economic Zoology and Entomology The point of view from which this book is written is explained in its first chapter. For that matter it is indicated clearly by the title. If the study of zoology is being neglected in schools for the alleged reason that it is not a useful study, the neglect is based on an unsound reason. For zoology is useful, and not in one way alone, but in two ways; and both of these in addition to its pedagogic value as a study which develops accurate personal observation and independent personal attainment of conclusion. Zoology is first of all useful in the way so often stressed by Huxley, as a study that gives us a sounder basis for our own life by showing the demands of Nature on animal life in general and the kinds of responses to be made to these demands. In other words it is quite specially a branch of science that can help us largely as a guide to living in conformity to natural laws. Zoology is also useful in a more obvious and commercially ratable way, by revealing the precise relation which many animals bear to us in their attitude of friends to be cultivated, or foes to be fought. Injurious insects, alone, cause this country an annual loss of a billion dollars. A general knowledge of insect life and an intelligent and vigorous application of this knowledge can save the nation half this loss. To the teacher intending to use this book as class guide there is due a word of explanation. The authors have attempted to make the book an introduction to general zoology as well as to that specific phase of it called economic. The first chapters are therefore of a nature to introduce pupils to general facts of animal structure and life. They are arranged on the basis of accepted pedagogic principles.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Outlines of Economic Zoology The book may be used in several ways. As followed by the author, the course may be given as a separate one to students who have already had the regular elementary course in general zoology. In this case the students will be familiar with the classification, structure and habits of most of the type forms discussed, but, if desired, additional labo ratory work may be arranged for the study of certain parasitic and other economically important forms not generally considered in a general laboratory course. Or, the text might be used in a beginning course in zoology by some amplification of the morphologic and other aspects and considerable increase in laboratory work. Again, it could well be used as supplementary reading with, say, one hour credit per semester for the year, in connection with the regular elementary course in general zoology. It is thought that, used in one or other of these ways or in some still different way, it should be especially useful to students in agriculture, who want a practical course. Various sources of information have been drawn upon, and recognized authorities in each subject consulted so far as possible. The publications of the Government, especially those of the Department of Agriculture, have been freely used and quoted. The figures have been borrowed largely, either from technical or from more popular works, whichever gave the best ideas of the animals portrayed; the source is indicated in every case. The brief bibliography at the end of the book is merely to aid the student, who may have become especially interested in some animal or group, to get more detailed information.

Book excerpt: The present book is a novel attempt to make available the students an exhaustive, interesting and valuable information on the subject of Economic Zoology. All kinds of animal pathogens such as protozoans, helminths, nematodes, mites and ticks and household insects, directly or indirectly causing diseases in other animals including humans, have been described in detail covering every aspect of their life history along with the symptoms appearing on the hosts, and their prevention, control and cure. Furthermore, along with the animal pathogens mentioned above, plant pathogens, such as insects, acting as pests of a variety of crops have also been described in full detail. Apart from the harmful effects, animals are also beneficial to mankind. This seems to be justified when we go through the chapters relating to apiculture, lac culture and sericulture along with fisheries, prawn culture, pearl culture, cattle farming, pig farming and poultry farming. In the second edition, the book introduces a section on 'Protozoans and Soil Fertility'. Besides, Multiple Choice Questions have been appended in each chapter to help students analysing the area of their strengths and weaknesses. Key Features Chapters enriched with photomicrographs present a realistic description. Exclusive life cycle diagrams of pathogens are helpful in understanding important events of their life. Exhaustive coverage of the subject matter helps students to understand the concepts with clarity and provide a wide range of information in a single volume. Chapter-end review questions help students to prepare for the examinations and assess their subject knowledge.

Book excerpt: Excerpt from School Entomology: An Elementary Textbook of Entomology Entomology is briefly defined as the study of insects in all their relations and activities. Its importance is due to the numbers of species and the abundance of individuals in the insect group. In both these respects insects form by far the greater portion of our land fauna. Various estimates place the number of species of insects at from one to ten millions and the number of individuals is far beyond calculation. Of these species nearly a half million have been named and described. The range of insects is almost universal on land, but only a few forms are marine in habitat. Intensively speaking, their range is equally great. In any given locality insects may be found inhabiting every conceivable situation and living on the greatest variety of foods. When we consider the vast numbers of insect forms and their wide distribution and range in food habits it seems inevitable that many of these forms should clash with man, and this is indeed the case. Many of the earths products which are most useful and highly desirable to man are attractive to insects as well. Man, in his assumed character of the dominant animal, claims prior right and such insects as affect his welfare or comfort are listed as pests. Less account is taken by man of his insect allies, those forms which minister directly to his needs, or those which, in a roundabout way, add to his pleasure or his revenues.
