Traps baited with sex pheromones were used to monitor field populations of longtailed and obscure mealybugs. Lures loaded with 25 microgram doses of racemic pheromones remained effective for at least 3 months. Pheromones could also be combined to make lures that attracted several species simultaneously. The numbers of insects caught in traps were correlated with mealybug abundance, indicating that pheromone traps can be used in place of laborious manual sampling to monitor populations. The efficacy of using pheromone traps to monitor seasonal fluctuations in mealybug populations was demonstrated.
For nearly 50 years, pest control was mostly based on broad-spectrum conv- tional insecticides such as organochlorines, organophosphates, carbamates and pyrethroids. However, the severe adverse effects of pesticides on the environment, problems of resistance reaching crisis proportions and public protests led to stricter regulations and legislation aimed at reducing their use. Ways to reduce the use of synthetic pesticides in plant protection and to use more alternative and novel me- ods for pest control or biorational control are the challenges of pest control for the twenty-first century. The term biorational (biological + rational) pesticides can be defined as the use of specific and selective chemicals, often with a unique modes of action, that are compatible with natural enemies and the environment, with minimal effect on n- target organisms. Biorational control is based on a diversity of chemical, biological and physical approaches for controlling insect pests which results in minimum risk to man and the environment.
This text presents an up-to-date account of the soft-scale insects, "Coccidae", and covers almost the entire spectrum of the knowledge of this insect family. It is divided into three sections, covering: soft scale insects; their natural enemies; and damage and control.
Provides a state-of-the-science overview of arthropods affecting grape production around the world. Vineyard pest management is a dynamic and evolving field, and the contributed chapters provide insights into arthropods that limit this important crop and its products. Written by international experts from the major grape-growing regions, it provides a global overview of arthropods affecting vines and the novel strategies being used to prevent economic losses, including invasive pests affecting viticulture. The book contains reviews of the theoretical basis of integrated pest management, multiple chapters on biological control, current status of chemical control, as well as in-depth and well-illustrated reviews of the major arthropod pests affecting grape production and how they are being managed worldwide. This text will serve as a primary resource for applied entomologists, students, growers, and consultants with interests at the intersection of viticulture and applied entomology.
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.
This Colour Handbook reviews the natural predators, parasites and pathogens used to control pest populations and analyses their characteristics and practical applications. It is designed to enable the reader to anticipate, recognise and resolve specific problems of pest management. Intended as a concise accessible reference to the field, this book will be of interest to a broad spectrum of academic, professional and lay readers; the growers and the consultants advising them, students in horticulture and crop science and scientists in a broad range of related disciplines. ∗ Superb, detailed colour photographs and line drawings of predator, parasite and pest species. ∗ Accessible, practical format. ∗ Covers all the major commercial planting environments; Arable, Orchard, Glasshouse and Ornamental (parks and gardens). ∗ Unique world wide coverage. ∗ Comperhensively corss–referenced by crop, pest, and pest control species (parasites and predators).
This book provides a complete overview of cutting-edge research on insect sex pheromones and pheromone communication systems. The coverage ranges from the chemistry, biosynthesis, and reception of sex pheromones to the control of odor-source searching behavior, and from molecules to the application of research findings to robotics. The book both summarizes the progress of studies conducted using Bombyx mori and several groups of moths and reviews sex pheromones of some non-lepidopteran insect groups of agricultural importance. Attention is drawn to recent findings on elaborate neural information processing in the brain in male moths and to the importance of olfactory receptors specifically tuned to sex pheromone molecules. Featuring contributions from leading experts on the topic, this book will be a unique and valuable resource for researchers and students in the fields of entomology, chemical ecology, insect physiology and biochemistry, evolution, biomimetics, and bioengineering. In addition to researchers, general insect lovers will find the book fascinating for its descriptions of the marvelous abilities of insects and the underlying mechanisms involved.
