Download or read book Handbook to the Construction and Use of Insect Collection and Rearing Devices written by Gregory S. Paulson and published by Springer Science & Business Media. This book was released on 2005-04-27 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a compilation of techniques and devices for collecting and rearing insects that should appeal to educators as well as professional or amateur entomologists. Insects are easy to collect and raise and have a fascinating array of life histories, which make them great for classroom studies. With minimal space and costs, colonies of insects can be raised in classrooms for use in behavioral and physiological studies. The small size and tremendous reproductive capacity of insects are ideal for ecological studies of dispersion, predation, parasitism and reproduction in compressed timeframes and small areas relative to similar studies of larger organisms. This book explains the various techniques of how to build rearing devices and use insect collecting to stimulate insect exploration. Anyone with basic hand tools, a little skill, and patience can construct these devices. A materials list, instructions for assembly, construction tips, and photographs are included for each device discussed in the text. Most of them require less than 1 hour assembly time and cost very little because they can be made from recycled items. There is also a review of simple statistics for use in the classroom, and, if appropriate, suggestions for classroom projects including simple statistical analyses.

Available in PDF, EPUB and Kindle. Book excerpt: Insects and non-insect pests are responsible for causing extensive damage to crops in the field and to grains and stored products in the warehouses and godowns, which necessitates their control. In this book, the author has given:- Detailed account of major insect and non-insect pests of economically important field and horticultural crops and possible measures of their control. Information about household pests, which damage human possessions, as well as insect and non-insect pests, which either cause diseases or transmit various diseases in plants, livestock and humans. A list of minor pests of each crop, which may attain the level of major pests when conditions become favorable for them. List of insecticides approved by the Government of India for use as spray chemicals and granular insecticides and the dosage for their use. The text is substantiated with many, fine hand-drawn illustrations, depicting the nature of damage and life cycle of the pests, which is the highlight of this book. The book is intended primarily for the Under Graduate students of Agriculture, but it will be immense use for the Post Graduate students of Agriculture, officials working in the Department of Agriculture, those interested in scientific farming and for the general public.
Download or read book Ecological Methods written by T.R. Southwood and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: The virtual impossibility of extracting the many different species from a habitat with equal efficiency by a single method (e.g. Nef, 1960). 1.1 Population estimates Population estimates can be classified into a number of different types; the most convenient classification is that adopted by Morris (1955), although he used the terms somewhat differently in a later paper (1960). 1.1.1 Absolute and related estimates The animal numbers may be expressed as a density per unit area of the ground of the habitat. Such estimates are given by nearest neighbour and related techniques (Chapter 2), marking and recapture (Chapter 3), by sampling a known fraction of the habitat (Chapter 4-6) and by removal sampling and random walk techniques (Chapter 7). Absolute population The number of animals per unit area (e.g. hectare, acre). It is almost impossible to construct a budget or to study mortality factors without the conversion of population estimates to absolute figures, for not only do insects often move from the plant to the soil at different developmental stages, but the amount of plant material is itself always changing. The importance of obtaining absolute estimates cannot be overemphasized.
