This book was released on 2018-09-10 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Study of Compsilura Concinnata, an Imported Tachinid Parasite of the Gipsy Moth and the Brown-Tail Moth Since 1891, when the gipsy moth covered an area of approximately 200 square miles, it has spread until m 1916 it involved 20715 square miles, and is found in all of the New England States. In some localities ln Massachusetts, Where it was once accounted a plague, the Severity of the infestation has been reduced to such an extent that the pest is more easily controlled. The brown tail moth was first regarded as a serious problem in 1897, when it was found 111 15 towns close to Boston. Since then it has spread until now (1916) it covers a territory of Square miles, occurring in all of the New England States. Both sexes of the brown-tail moth are strong fliers. This important factor helps to explain why this insect is found over a larger area than the gipsy moth, the female of the latter species being unable to fly.

Download or read book Beneficial Insects written by David V. Alford and published by CRC Press. This book was released on 2019-04-23 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects are key components of life on our planet, and their presence is essential for maintaining balanced terrestrial ecosystems. Without insects humans would struggle to survive, and on a world scale food production would be severely compromised. Many plants and animals depend directly or indirectly on insects for their very survival, and this is particularly so in the case of insectivorous birds and other such creatures. The beneficial role of insects is often overlooked or misunderstood, and in farming circles their very presence on crops is often seen to be unwelcome. In reality, however, many insects are genuinely beneficial, as in the case of parasitic and predacious species. The use of chemical pesticides to control crop pests is becoming more tightly regulated and environmentally undesirable, and low-input farming, in which natural enemies of pests are encouraged to survive or increase, is becoming far more prevalent. Accordingly, Integrated Pest Management (IPM) and Integrated Pest Management (ICM) strategies are increasingly being developed, advocated and adopted. Features: Highlights information on many groups of insects and mites that act as natural enemies or biological control agents of phytophagous insects and mites, including plant pests. Profusely illustrated with high-quality colour photographs. Focuses mainly on insects and mites as natural enemies of plant pests, including parasitic and predacious species that have been accidentally or deliberately introduced in classical biological control programmes. Reviews the role of phytophagous European insects and mites in controlling or managing European plants that have become invasive weeds in other parts of the world, notably North America, Australia and New Zealand.
Download or read book Parasitoids written by H. Charles J. Godfray and published by Princeton University Press. This book was released on 2019-12-31 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parasitoids lay their eggs on or in the bodies of other species of insect, and the parasitoid larvae develop by feeding on the host, causing its eventual death. Known for a long time to applied biologists for their importance in regulating the population densities of economic pests, parasitoids have recently proven to be valuable tools in testing many aspects of evolutionary theory. This book synthesizes the work of both schools of parasitoid biology and asks how a consideration of evolutionary biology can help us understand the behavior, ecology, and diversity of the approximately one to two million species of parasitoid found on earth. After a general introduction to parasitoid natural history and taxonomy, the first part of the book treats the different components of the reproductive strategy of parasitoids: searching for a host, host selection, clutch size, and the sex ratio. Subsequent chapters discuss pathogens and non-Mendelian genetic elements that affect sexual reproduction; evolutionary aspects of the physiological interactions between parasitoid and host; mating strategies; life history theory and community ecology. A special effort is made to discuss the theoretical background to the subject, but without the use of mathematics.

Download or read book Colour Identification Guide to the Moths of the British Isles written by Bernard Skinner and published by BRILL. This book was released on 2013-01-21 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Now re-published with additional and updated text, the third edition of the renowned guide to British macro lepidoptera contains two new plates of additional species plus a further group of colour plates comparing critical species in a new style to aid identification of groups of moths. The last twenty-five years since the publication of the first edition have seen a steady increase in our knowledge of British macro moths, their distribution, history and habits, and this new edition will bring to both the new and experienced student of the group, the latest overview of current status of resident, immigrant and historical records. Since the publication of the second edition very significant changes in behaviour and distribution, perhaps associated with climate change, have made it desirable to update much of the basic text. The author, Bernard Skinner has once again prepared an updated concise text giving the fullest details available in a single volume of the British and Irish moths. Here are new records, new species to Great Britain and Ireland together with historical information. Once again the concept of a clear range of illustrations, both drawings and colour photographs provide the basis for identifying moths. Together with a text that indicates similar species, are drawings that point towards diagnostic features of similar moths. The main block of forty-five colour plates illustrate the size, complete wing patterns and important forms and variation of moths. New additional plates bring together magnified images of various groups of moths, some separated in the main plates, to help compare similar species and aid identification using in some cases underside illustrations where advantageous. This is a major update of the 2nd edition that has been out of print for the last couple of years.
Download or read book An Introduction to Biological Control written by A.P. Gutierrez and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a revision of Biological Control by R. van den Bosch and P. S. Messenger, originally published by Intext Publishers. In the revision, I have attempted to keep the original theme, and to update it with current research findings and new chapters or sections on insect pathology, microbial control of weeds and plant pathogens, population dynamics, integrated pest management, and economics. The book was written as an undergraduate text, and not as a complete review of the subject area. Various more comprehen sive volumes have been written to serve as handbooks for the experts. This book is designed to provide a concise overview of the complex and valuable field of biological control and to show the relationships to the developing concepts of integrated pest management. Population regulation of pests by natural enemies is the major theme of the book, but other biological methods of pest control are also discussed. The chapter on population dynamics assumes a precalculus-level knowledge of mathematics. Author names of species are listed only once in the text, but all are listed in the Appendix. Any errors or omissions in this volume are my sole responsibility. A. P. Gutierrez Professor of Entomology Division of Biological Control University of California, Berkeley vii Acknowledgments Very special thanks must be given to my colleagues, Professors C. B. Huffaker and L. E. Caltagirone, for the very thorough review they provided and for the many positive suggestions they gave. Dr.
