Book Description
The present work aimed to study firstly in the laboratory the characteristic of a new type biocide GCSC-BtA (Germany-China Scientific Cooperation-Bacillus thuringiensis-Abamectin) by using HPLC as well as its efficiency on different agricultural pests and their natural enemies. The modes of action of GCSC-BtA on insecticidal activity, antifeedant effect and sublethal effect were also determined. Further experiments were devoted to investigate the factors affecting its efficiency to pests. Finally, field experiments were carried out to estimate the efficiency of GCSC-BtA against pests and its side-effect on natural enemies in alfalfa pasture, tea garden and broccoli field. All these experiments have the goals to enrich application characteristics of this promising biocide and so its use in biological control programs against agricultural arthropod pests. Das Ziel der vorliegende Arbeit war zunächst die Untersuchung der Eigenschaften eines neunen Typs von Biozid GCSC-BtA (Germany-China Scientific Cooperation-Bacillus thuringiensis- Abamectin) mit Hilfe der HPLC-Analytik als auch dessen Wirksamkeit gegenüber unterschiedlichen landwirtschaftlichen Schädlingen und deren natürlichen Feinden. Der Wirkungsmechanismus von GCSC-BtA in bezug auf dessen insektizide, fraßhemmende und subletale Wirkung war ebenfalls Gegenstand dieser Untersuchungen. Weitere Experimente erfolgten zur Erfassung der Einflussfaktoren auf die Wirksamkeit dieses Biozids. Abschließend wurden Freilanduntersuchungen zur Ermittlung der Effektivität von GCSC-BtA gegenüber Schädlingen sowie dessen Nebenwirkungen auf die natürlichen Feinde dieser Schädlinge in Alfalfafeldern, Teeplantagen und Broccolikulturen durchgeführt. Ziel all diese Untersuchungen war die Ermittlung der Wirkungsmechanismen dieses vielversprechenden Biozids und dessen Einsatz in der biologischen Schädlingsbekämpfung gegenüber landwirtschaftlichen Schadarthropoden.

Book Description
Entomopathogenic bacteria (Bacillus thuringiensis and B. sphaericus) are increasingly used as biopesticides to control larval insect populations which are either agricultural or forestry pests and to reduce those which as adults are vectors of severe human diseases. This new book, the first since 1993 to address all aspects of entomopathogenic bacteria, provides undergraduate and graduate students as well as research scientists with a complete, modern view of this important group of bacteria. The authors, chosen for their sustained contributions to the field, cover both fundamental and applied research in this area. The main topics include bacterial ecology and taxonomy, toxin diversity, activity and mode of action, regulation and environment of the genes, safety and ecotoxicology, production and field application of the bacteria, and outbreaks of resistant populations. The book concludes with the most recent data obtained on transgenic biotechnology and addresses environmental impact issues.

Book Description
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.

Book Description
Worldwide, soybean seed proteins represent a major source of amino acids for human and animal nutrition. Soybean seeds are an important and economical source of protein in the diet of many developed and developing countries. Soy is a complete protein and soyfoods are rich in vitamins and minerals.Soybean protein provides all the essential amino acids in the amounts needed for human health. Recent research suggests that soy may also lower risk of prostate, colon and breast cancers as well as osteoporosis and other bone health problems and alleviate hot flashes associated with menopause. This volume is expected to be useful for student, researchers and public who are interested in soybean.

Book Description
The future of insect control looked very bright in the 1950s and 1960s with new insecticides constantly coming onto the market. Today, however, whole classes of pesticide chemistry have fallen by the wayside due to misuse which generated resistance problems reaching crisis proportions, severe adverse effects on the environment, and public outcry that has led to increasingly stricter regulation and legislation. It is with this background, demanding the need for safer, environmentally friendly pesticides and new strategies to reduce resistance problems, that this book was written. The authors of the various chapters have a wealth of experience in pesticide chemistry, biochemical modes of action, mechanism of resistance and application, and have presented concise reviews. Each is actively involved in thedevelopment of new groups of pesticide chemistry which led to the development of novel insecticides with special impact in controlling agricultural pests. Emphasis has been given to insecticides with selective properties, such as insect growth regulators hormone mimics, ecdysone agonists), (chitin synthesis inhibitors, juvenile chloronicotinyl insecticides (imidacloprid, acetamiprid), botanical insecticides (neem, plant oils), pymetrozine, diafenthiuron, pyrrole insecticides, and others. The importance of these compounds, as components in integrated pest management programs and in insecticide resistance management strategies, is discussed. The data presented are essential in establishing new technologies and developing novel groups of compounds which will have impact on our future agricultural practices.

Book Description
Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), the spotted wing drosophila (SWD), is the most important pest affecting berry crop production worldwide. The global fresh fruit trade, coupled with the ability of the larvae to hide inside the fruit undetected until after transportation, facilitate their distribution. SWD is native to Asia, but is increasingly found in other regions: occurrences have been recorded in the Americas and Europe, and Africa, and the insects have the potential to adapt and become established in Oceania. Gathering the experiences of leading scientists in the management of D. suzukii around the globe, the book addresses D. suzukii monitoring; biological, chemical and cultural control; sterile insect technique (SIT); integrated pest management (IPM), and other control methods. It also discusses the use of drones, GPS, biotechnology, telemetry and other technological tools to make the management of this pest more efficient and accurate. As such, it is a valuable resource for scientists, professionals and students.
