Esta guía, fruto del resultado de más de veinte años de trabajos, presenta los principales grupos de enemigos naturales de plagas que pueden encontrarse en los espacios verdes. Es una herramienta de soporte para gestores y tecnicos relacionados con el control de plagas en ecosistemas urbanos y tambien para el publico en general, interesado en la biodiversidad de fauna de los parques y jardines de nuestras ciudades y pueblos.Dirigidas a los tecnicos y gestores, se realizan descripciones de los principales grupos de enemigos naturales que se pueden encontrar en Cataluña y en el resto del Estado español. Se aporta informacion sobre los principales grupos de depredadores (insectos, aracnidos, aves, mamiferos), parasitoides (insectos) y patogenos (nematodos, hongos y otros). Tambien se indican las especies mas habituales de cada grupo, con que plagas se relacionan y en que habitats se pueden encontrar. Al final de la guia se incluye una clave para la identificacion de adultos de los principales enemigos naturales.

Invasions of introduced species cause varying degrees of harm on the ecosystems in question and it is up to society to deal with the consequences. How can we prevent biological invasions? How can we assess the risk they represent? What can be done to control current invasions? Aware of this problem, the Ministry of Ecology has requested a community of researchers from a variety of disciplines to decipher these questions using biological, sociological and economic approaches. Although the definitive response to the problems raised by invasive species in natural spaces is not provided here, undeniable progress in understanding mechanisms underlying these invasions can shed light on the decisions which have to be taken by environmental managers. Scientists, teachers and students will also find results and thought-processes in this book to supplement their knowledge.

Plutella xylostella (DBM) is a key pest of crucifers resistant to many insecticides and some crystalendotoxins. Biological control based IPM and classical biocontrol have had varied success. How can it be improved? This book presents key papers and the proceedings of an international symposium held in Montpellier (France) in October 2002. The status of Plutella and control measures used in different areas of the world are discussed, and recommendations for improving biocontrol are made.

This joint-authored book brings together approximately 50 current research methods developed and implemented in research laboratories in Europe to study pesticide/soil interactions. Its usefulness for researchers, teachers and professionals concerned by the environmental impact of pesticides was one of the major elements taken into consideration when structuring this book. It will be a valuable asset to chemists, physical chemists, biochemists, biologists and geologists interested in studying the behaviour of pesticides in soils.

Among the many challenges facing the contemporary smallholder who keeps livestock and grows his own food, is how to deal with the various pests that are capable of decimating crops, degrading pasture, stealing produce, contaminating animal feed and killing valuable livestock. This book provides the smallholder with the knowledge and the information about the skills to meet this challenge in an effective and humane way.Considers all the major pests faced by smallholders including rats, house and field mice, grey squirrels, moles, rabbits, deer, foxes, mink, wood pigeons, crows and rooks. Discusses each pest in detail, arguing that it is essential for the smallholder to understand their characteristics and behaviour in order to control them successfully. Emphasizes that prevention is better than cure and identifies a variety of measures designed to thwart, rather than kill, pests. Examines both traditional and modern pest control methods. Covers traps, poisons, air rifles, dogs, ferrets, electric fencing, bird scarers, wildlife deterrents and repellents, automatic bird feeders, and polytunnels and cloches. Stresses that smallholders need to adopt a comprehensive pest control programme that complies with current legislation and balances conservation with control. An invaluable and well-illustrated book that provides the smallholder with the knowledge required to deal efficiently and humanely with the various pests that present a constant challenge. Essential reading for small-scale farmers, smallholders and those with large gardens attached to properties in the countryside. Superbly illustrated with 146 colour photographs. David Bezzant has been a smallholder for all his adult life and is an expert on the use of old-fashioned forms of pest control.

If you are a gardener, groundsman, smallholder or farmer and have a mole problem, then this book will be of enormous help to you. Pest-control books normally only devote a paragraph or two to moles and rarely cover the subject in detail. This volume is very different and is probably one of the most comprehensive books ever written on mole trapping. Throughout the book, Jeff Nicholls, a professional mole catcher, reveals his enormous respect for the mole and emphasizes the absolute need to control these rarely seen animals using humane and traditional methods that have been proven to work effectively. At the outset the author discusses the natural history of the mole and explains its characteristics and behaviour, an understanding of which is essential if successful catching techniques are to be applied. He then discusses in detail the traditional and humane methods he uses in different terrain and weather conditions, considers how to locate mole runs, describes all the different types of traps that can be employed and explains how to set the traps correctly.

It is of paramount importance to improve application techniques when controlling locust outbreaks in developing countries. Most available documents and publications on locust control deal mainly with insecticides, rather than application techniques and the required control equipment. The present guide book is designed to make up for this oversight. Basic principles for conducting spraying operations, descriptions of spraying equipment - especially for ultra low volume spraying - and specific locust control techniques are described in detail. The document explains how to get the most from treatments while minimizing the adverse effects to the man and environment. This book is aimed at decision-makers and all those involved in locust control who wish to improve their knowledge of application techniques.
