In further oviposition studies, females laid fewer eggs in naturally infested pepper fruits in cage and small arena studies. A host marking pheromone responsible for the deterrence was identified in the oviposition plug and frass of female weevils. This compound or compounds are slightly polar with low volatility and are potential candidates for use in pest management programs. An investigation into the response of pepper weevil to host plant volatiles found that 10-d-old males and 2 and 10-d-old females oriented to the volatiles of three host plants (pepper, American black nightshade, and eggplant). Only 10-d-old males and females could perceive differences in volatile plumes, ignoring volatiles from non-host plants outside the Solanaceae. Ten-d-old males and females were also strongly attracted to pepper plants with actively feeding female weevils. It is hoped that by combining this knowledge of the deterrent pheromone and attractive plant volatiles, a new tool for pepper weevil pest management can be developed.
This text brings together fundamental information on insect taxa, morphology, ecology, behavior, physiology, and genetics. Close relatives of insects, such as spiders and mites, are included.
Set includes revised editions of some issues.
Integrated Pest Management: Current Concepts and Ecological Perspective presents an overview of alternative measures to traditional pest management practices using biological control and biotechnology. The removal of some highly effective broad-spectrum chemicals, caused by concerns over environmental health and public safety, has resulted in the development of alternative, reduced risk crop protection products. These products, less toxic to the environment and easily integrated into biological control systems, target specific life stages or pest species. Predation — recognized as a suitable, long-term strategy — effectively suppresses pests in biotechnological control systems. Integrated Pest Management covers these topics and more. It explores the current ecological approaches in alternative solutions, such as biological control agents, parasites and predators, pathogenic microorganisms, pheromones and natural products as well as ecological approaches for managing invasive pests, rats, suppression of weeds, safety of pollinators, role of taxonomy and remote sensing in IPM and future projections of IPM. This book is a useful resource to entomologists, agronomists, horticulturists, and environmental scientists. - Fills a gap in the literature by providing critical analysis of different management strategies that have a bearing on agriculture, sustainability and environmental protection - Synthesizes research and practice on integrated pest management - Emphasizes an overview of management strategies, with critical evaluation of each in the larger context of ecologically based pest management
The group of plants known as 'peppers' is diverse, containing types that contribute to the fresh and processed food markets as well as varieties that are used in pharmaceuticals and other non-food commercial products. Peppers originally developed in tropical regions, but are now grown and used in every country where it is possible to grow them, including in areas where production is difficult. This book examines peppers from historical, genetic, physiological and production perspectives, following the development of the cultivated crop from the wild type. Diverse examples of pod types and thei.
The book summarizes the history of biological control in Latin America and the Caribbean. Few publications provide historical detail and the records are, therefore, fragmented until now. By bringing information together in this book, we offer a more complete picture of important developments in biological control on this continent. There are a wealth of text, tables and references about the history of such projects, and which were succesful and which failed. This will help plan future biocontrol projects. An overview is provided of the current situation in biological control for many Latin American and Caribbean countries, revealing an astonishing level of practical biological control applied in the regio, making it the largest area under biological control worldwide. The final part describes new developments and speculates about the future of biological control in Latin America and the Caribbean.
