Available in PDF, EPUB and Kindle. Book excerpt: Nejprve autor probírá výzkumné metody populační dynamiky škůdce hrachových listů mšice Acyrthosiphon pisum Harris a zabývá se v dalších kapitolách celou parazitologickou problematikou tohoto škůdce. V souvislosti s ním věnuje pozornost i specii Aphidius ervi. Provádí srovnání výzkumných metod, pojednává o braní vzorků z populace parazitů, studuje jejich biotypy a účinky insekticidů. Zabývá se jejich taxonomií a relativní četností jejich výskytu v ČSSR, jehož prognózu provádí na základě analýzy povětrnostních podmínek a hodnotí i úlohu zvláštních faktorů výskytu.

Available in PDF, EPUB and Kindle. Book excerpt: Most people know of aphids as garden pests, infesting the soft green tissues of plants in vast numbers and killing them by sucking out the sap. Indeed, among the 4000 or so known species of aphids about 250 are pests, and in temperate regions several are economically important agricultural pests that damage crops directly during feeding or act as v

Download or read book Handbook of Biological Control written by T. W. Fisher and published by Elsevier. This book was released on 1999-09-20 with total page 1073 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many years the use of chemical agents such as pesticides and herbicides has been effective in controlling the many varieties of pests that infest both agricultural crops and backyard gardens. However, these pests are gradually becoming resistant to these agents, because the agents themselves are acting as selective factors making the pests better and better able to resist and persist. As a result, the use of biological controlling agents is increasing. This book is a comprehensive and authoritative handbook of biological control.
Download or read book Behavioral Ecology of Insect Parasitoids written by Eric Wajnberg and published by John Wiley & Sons. This book was released on 2008-04-30 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: Written by a team of leading international specialists, Behavioral Ecology of Insect Parasitoids examines the optimal behaviors that parasitoids exhibit in order to maximize long term offspring production. It is an essential reference for research scientists and students studying these fascinating insects or for anyone involved in using parasitoids in biological control programs. Reviews topical issues, including cutting edge research on parasitoid decision making and the implications for biological control Explores applications in other fields, provides information on the latest research methods, and includes helpful case studies and statistical tools Creates a deeper understanding of the link between behavioural strategies and host mortality, resulting in more efficient selective pest management programs “Overall, this is a fascinating volume that provides a significant contribution to the literature on parasitoid insects. It goes a long way toward providing insights into numerous aspects of parasitoid behavior and will stimulate a diversity of future projects, something that should be the goal of any such text. I highly recommend Wajnberg et al. for all of those working on the biology or evolution of parasitoids.” Palaios 2009

Download or read book Aphids as Crop Pests 2nd Edition written by Helmut F van Emden and published by CABI. This book was released on 2017-08-23 with total page 716 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aphids are among the major global pest groups, causing serious economic damage to many food and commodity crops in most parts of the world. This revision and update of the well-received first edition published ten years ago reflects the expansion of research in genomics, endosymbionts and semiochemicals, as well as the shift from control of aphids with insecticides to a more integrated approach imposed by increasing resistance in the aphids and government restrictions on pesticides. The book remains a comprehensive and up-to-date reference work on the biology of aphids, the various methods of controlling them and the progress of integrated pest management as illustrated by ten case histories.
