This book was released on 2017-11-19 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Plant-Bugs Injurious to Cotton Bolls Damage by the boll weevil has brought into prominence many other insects which attack the cotton plant, the work of which has been largely overlooked. Among the most important of these minor insects are various species of plant-bugs. Many of these have been known as enemies of the cotton plant for some years, but they have received only slight attention from economic entomologists. When their damage is added to the injury done by the cotton boll weevil, still further reducing the crop, they become of such importance that full knowledge of their habits and life history is demanded. The studies upon which this bulletin is based were conducted to add to our knowledge of the biology of an important group of insect pests and of the most practical and efficient methods by which they may be controlled.

Book excerpt: Excerpt from Insect and Other Animal Pests of Cinchona and Their Control in Puerto Rico Earthworms. - Earthworms of undetermined species have some times caused trouble ih nursery beds made of forest duff, a spongy, friable, humus material matted with tree roots. The worms impeded drainage and aeration by rapidly breaking down the organic matter in the duff and bringing up into the mixture large quantities of soil. Beds built over subsoil tended to remain uninfested for a much longer period than those built over topsoil. Damage was overcome to some extent by removing the topsoil before constructing the bed (7, p. Cats - Wild house cats frequently do a great deal of damage in seedbeds and freshly prepared and planted nursery beds by scratching around in the loose planting medium. For complete protection it has been necessary to enclose the beds in wire netting. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book Hibernation of the Mexican Cotton Boll Weevil Classic Reprint written by W. E. Hinds and published by Forgotten Books. This book was released on 2019-02-12 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Hibernation of the Mexican Cotton Boll Weevil Until this time the hibernation of the bell weevil has been less understood than any other phase of its life history. This was due to the great difficulty in obtaining the necessary data and the fact that the phenomena of hibernation are not necessarily identical in different seasons. In fact, it will be seen from the following pages that there have been very important dissimilarities between the years when special observations have been under way. The necessary repeated work in large cages in different localities has now been carried on and extensive field observations have been made in various representative parts of the infested area as to the natural situations in which the hibernating weevils occur. As a result, the present bulletin will make the life history of the bell weevil during the winter season at least as well known as any other portion of its biology. In the work leading to this bulletin practical considerations have always received primary attention. However, it has repeatedly been shown that careful detailed investigations of injurious insects may result in important suggestions for control that are not foreseen at the beginning of the work. Therefore the tepic of the hibernation of the boll weevil has been investigated from every possible standpoint. Its importance, as a critical period in the life history of a most injuri ous pest, has abundantly warranted this work.

Download or read book Edible Insects written by Arnold van Huis and published by Bright Sparks. This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Edible insects have always been a part of human diets, but in some societies there remains a degree of disdain and disgust for their consumption. Although the majority of consumed insects are gathered in forest habitats, mass-rearing systems are being developed in many countries. Insects offer a significant opportunity to merge traditional knowledge and modern science to improve human food security worldwide. This publication describes the contribution of insects to food security and examines future prospects for raising insects at a commercial scale to improve food and feed production, diversify diets, and support livelihoods in both developing and developed countries. It shows the many traditional and potential new uses of insects for direct human consumption and the opportunities for and constraints to farming them for food and feed. It examines the body of research on issues such as insect nutrition and food safety, the use of insects as animal feed, and the processing and preservation of insects and their products. It highlights the need to develop a regulatory framework to govern the use of insects for food security. And it presents case studies and examples from around the world. Edible insects are a promising alternative to the conventional production of meat, either for direct human consumption or for indirect use as feedstock. To fully realise this potential, much work needs to be done by a wide range of stakeholders. This publication will boost awareness of the many valuable roles that insects play in sustaining nature and human life, and it will stimulate debate on the expansion of the use of insects as food and feed.

Available in PDF, EPUB and Kindle. Book excerpt: As well as examining successful biological control programmes this book analyses why the majority of attempts fail. Off-target and other negative effects of biological control are also dealt with. Chapters contributed by leading international researchers and practitioners in all areas of biological control afford the book a breadth of coverage and depth of analysis not possible with a single author volume. Combined with the use of other experts to review chapters and editorial oversight to ensure thematic integrity of the volume, this book provides the most authoritative analysis of biological control published. Key aspects addressed include how success may be measured, how successful biological control has been to date and how may it be made more successful in the future. With extensive use of contemporary examples, photographs, figures and tables this book will be invaluable to advanced undergraduate and postgraduate students as well as being a `must' for all involved in making biological control successful.
