Book excerpt: Insects are key components of life on our planet, and their presence is essential for maintaining balanced terrestrial ecosystems. Without insects humans would struggle to survive, and on a world scale food production would be severely compromised. Many plants and animals depend directly or indirectly on insects for their very survival, and this is particularly so in the case of insectivorous birds and other such creatures. The beneficial role of insects is often overlooked or misunderstood, and in farming circles their very presence on crops is often seen to be unwelcome. In reality, however, many insects are genuinely beneficial, as in the case of parasitic and predacious species. The use of chemical pesticides to control crop pests is becoming more tightly regulated and environmentally undesirable, and low-input farming, in which natural enemies of pests are encouraged to survive or increase, is becoming far more prevalent. Accordingly, Integrated Pest Management (IPM) and Integrated Pest Management (ICM) strategies are increasingly being developed, advocated and adopted. Features: Highlights information on many groups of insects and mites that act as natural enemies or biological control agents of phytophagous insects and mites, including plant pests. Profusely illustrated with high-quality colour photographs. Focuses mainly on insects and mites as natural enemies of plant pests, including parasitic and predacious species that have been accidentally or deliberately introduced in classical biological control programmes. Reviews the role of phytophagous European insects and mites in controlling or managing European plants that have become invasive weeds in other parts of the world, notably North America, Australia and New Zealand.

Available in PDF, EPUB and Kindle. Book excerpt: Oilseed rape, a major crop in many parts of the world, is attackedby a wide range of insect pests, many of which are of considerableeconomic importance. With the increasing demand to reduceagrochemical inputs on arable crops, the Commission of the EuropeanCommunities supported a three-year programme in which scientificparticipants reviewed the natural enemies of oilseed rape insectpests. The various outputs from this important work form the basisof this comprehensive new book. Biocontrol of Oilseed Rape Pests commences with a reviewof the oilseed rape crop, followed by chapters on pests, pestmanagement strategies and parasitoids of specific pests or groupsof pests. Detailed information is also included on sampling,trapping and rearing pests, their parasitoids and predators; theidentification of hymenopterous parasitoids; pathogens of oilseedrape pests, predators, predator taxonomy and identification, andthe impact of on-farm landscape structures and systems onpredators. This book is an essential purchase for all those involved withoilseed rape and for anyone with an interest in agriculturalbiocontrol strategies. It is also essential reading and aninvaluable source of reference for agricultural scientists,entomologists, crop protection specialists, advisers andconsultants. All agrochemical companies should have multiple copiesof this book on their shelves, as should all libraries inuniversities and research establishments where biological andagricultural sciences are studied and taught. Dr David V. Alford, based in Cambridge, UK, has manyyears of experience working as a government entomologist.
