Book Description
Their natural enemies largely determine the population size and dynamic behavior of many plant-eating insects. Any reduction in enemy number can result in an insect outbreak. Applied biological control is thus one strategy for restoring functional biodiversity in many agroecosystems. Predators and Parasitoids addresses the role of natural enemies i

Book Description
The abundance of insects can change dramatically from generation to generation; these generational changes may occur within a growing season or over a period of years. Such extraordinary density changes or "outbreaks" may be abrupt and ostensibly random, or population peaks may occur in a more or less cyclic fashion. They can be hugely destructive when the insect is a crop pest or carries diseases of humans, farm animals, or wildlife. Knowledge of these types of population dynamics and computer models that may help predict when they occur are very important. This important new book revisits a subject not thoroughly discussed in such a publication since 1988 and brings an international scale to the issue of insect outbreaks. Insect Outbreaks Revisited is intended for senior undergraduate and graduate students in ecology, population biology and entomology, as well as government and industry scientists doing research on pests, land managers, pest management personnel, extension personnel, conservation biologists and ecologists, and state, county and district foresters.

Book Description
Insects and other pests cause major economic damage on fruit crops in the tropics. However, some insects are beneficial and have a role in pollinating flowers and thus enabling a fruit set. This book, written by leading authors from around the world, reviews the injurious and beneficial organisms and how they might be controlled to enhance fruit production and quality.

Book Description
The book covers the life history and control of over 200 species of harmful insects present in the Mediterranean Basin, and the information provided may also apply to other areas with a Mediterranean or subtropical climate, such as in areas of North and South America, southern Africa, Asia and Australia. The over 400 colour photographs gathered here will help the reader identify many of the cited species of insects.

Book Description
"Weaving science with personal observations, Morris demonstrates a knowledge of virtually every aspect of human-insect relations. Not only is this book useful in terms of the more practical side of entomology, it also provides a wealth of information on the role of insects in cultural production."--Jacket.

Book Description
The influence of insects on human life – destructive and beneficial – can be traced back to prehistoric days until now. Agricultural entomology concerns itself with the study of insects associated with various aspects of agriculture. It deals with the study of both beneficial and detrimental insects. Insects that are detrimental to agriculture are commonly known as insect pests. The bulk of agricultural entomology deals with the control of those. Insect pest control is now conducted through integrated pest management (IPM) principles that aim to be sustainable in the use of resources and environmentally friendly. IPM requires plenty of experience and knowledge and combines all available methods of control. Prevention is also an important component of IPM programs. In India, agriculture is the main occupation of the majority of people. The most important natural enemies of agricultural crops are insects, plant diseases, weeds and weather conditions. Out of this, insects are the greatest competitors of man in the struggle for existence. In the present topic the various kinds of pest will be studied in broad sense/view.
