Book excerpt: Excerpt from Plants Tested for or Reported to Possess Insecticidal Properties The most desirable type of plant is no doubt one which grows abundantly in a wild state, preferably in areas not readily adapted to the cultivation of valuable crops. Under such conditions the material could be obtained with the minimum of expense, the only cost being that of collection and preparation. Less abundant growth involves greater cost in collecting, and in case the plant must be cultivated it must bring sufficient return to compete with other crops adapted to that particular region. Perennials are much more desirable than annuals, since their products can usually be collected from year to year. Leaves and branches of trees or shrubs or the entire herbaceous portions of hard perennials can be most economi cally obtained. On the other han the collecting of fruits or seeds or the digging of roots or rhizomes can, as a rule, be much less economically done. In the case of small plants, gathering the roots usually means the destruction of the plant, which, in time, is likely to reduce the supply unless the plant is under cultivation. The character of the active constituent has an important bearing on the handling necessary in its preparation for the market. Sub stances like alkaloids and toxic resins are usually not subject to ready decomposition, and material containing such constituents need not be dried and handled with more than ordinary care. Oh the other hand, plant material depending for its action on glucosides must be carefully dried in order to inhibit decomposition of such constituents. In the case of plants native to foreign countries, especially the Tropics, this is an important matter, since the collecting is usually done by natives, and control of conditions of handling is likely to be difficult. Long voyages, especially by sea, are furthermore likely to cause deteriorating changes in such plant materials.

Download or read book Classical Biological Control of Bemisia tabaci in the United States A Review of Interagency Research and Implementation written by Juli Gould and published by Springer Science & Business Media. This book was released on 2008-03-01 with total page 343 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews interagency research and development of classical (importation) biological control of Bemisia tabaci (biotype B) conducted in the USA from 1992- 2002. The successful discovery, evaluation, release, and establishment of at least five exotic B. tabaci natural enemies in rapid response to the devastating infestations in the USA represents a landmark in interagency cooperation and coordination of multiple disciplines. The review covers all key aspects of the classical biocontrol program, beginning with foreign exploration and quarantine culture, through dev- opment of mass rearing methodology, laboratory and field evaluation for efficacy, to field releases, integration with other management approaches, and monitoring for establishment and potential non-target impacts. The importance of morphological and molecular taxonomy to the success of the program is also emphasized. The book’s contributors include 28 USDA, state department of agriculture, and univ- sity scientists who participated in various aspects of the project. Bemisia tabaci continues to be a pest of major concern in many parts of the world, especially since the recent spread of the Q biotype, so the publication of a review of the biological control program for the B biotype is especially timely. We anticipate that our review of the natural enemies that were evaluated and which have established in the USA will benefit researchers and IPM practitioners in other nations affected by B. tabaci.

Download or read book Insect Repellents Handbook Second Edition written by Mustapha Debboun and published by CRC Press. This book was released on 2014-09-19 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: The public has a great desire for products that prevent the annoyance of biting insects and ticks, but that desire does not always translate into sensible use of those products. Insect Repellents Handbook, Second Edition summarizes evidence-based information on insect repellents to inform decisions by those involved with insect repellent research, development, and use. This authoritative, single-source reference makes it possible for you to quickly gain a working level of expertise about insect repellents, without having to search through the scattered literature. The previous edition was the first comprehensive volume on this subject and quickly became the definitive reference on insect repellents. This second edition reflects the current state of insect repellent science, covers the processes involved in the development and testing of new active ingredients and formulations, and discusses the practical uses of repellents. The book includes thought-provoking discussions on how repellents work, their neuromolecular basis of action, and whether green chemistry can provide effective repellents. It also supplies an in-depth understanding of the development of repellents including testing methods, review of active ingredients, and the use of chemical mixtures as repellents. It provides science-backed chapters on repellent use including best practices for use of personal protection products, criteria for repellent use, and insect repellents for other potential use.

Download or read book BIOTECHNOLOGY Volume VI written by Horst W. Doelle and published by EOLSS Publications. This book was released on 2009-11-16 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: This Encyclopedia of Biotechnology is a component of the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Biotechnology draws on the pure biological sciences (genetics, animal cell culture, molecular biology, microbiology, biochemistry, embryology, cell biology) and in many instances is also dependent on knowledge and methods from outside the sphere of biology (chemical engineering, bioprocess engineering, information technology, biorobotics). This 15-volume set contains several chapters, each of size 5000-30000 words, with perspectives, applications and extensive illustrations. It carries state-of-the-art knowledge in the field and is aimed, by virtue of the several applications, at the following five major target audiences: University and College Students, Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers and NGOs.

Download or read book Molecular Insect Science written by H.H. Hagedorn and published by Springer Science & Business Media. This book was released on 1991-01-31 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the scientific papers and abstracts of posters presented at the International Symposium on Molecular Insect Science held in Tucson, Arizona, October 22-27, 1989. This meeting was organized by the Center for Insect Science at the University of Arizona in response to the growing need for a forum dedicated to the impact of modern biology on insect science. While scientific studies of a few insects, notably Drosophila melanogaster, have always had a central role in the development of biology, it is only recently that tools have become available to extend these studies to other insects, including those having economic and medical importance. The Tucson meeting was evidence of how far we have come in extending modern biological tools to the study of insects. It is also evident from the contents of this book that the study of insects is making an increasingly important contribution to the advancement of biology generally. Given the large impact of insects on human life, such a development has considerable importance for human welfare, and of the welfare of the ecosystem as a whole. It should be noted that several of the participants who presented posters were invited to prepare full length papers to ensure that the book covered the major areas of insect science. The financial support of the National Science Foundation and the Monsanto Corporation is gratefully acknowledged. Thanks are also due to Sharon Richards for her dedicated work on the manuscripts.
