Available in PDF, EPUB and Kindle. Book excerpt: Planthoppers include some of the most devastating pests of major agricultural crops throughout the world. One species, the rice brown planthopper, is among the most economically important pests in Asia. In past decades, government policies encouraged the control of rice planthoppers with synthetic pesticides, a tactic which promoted insecticide resistance and often led to the pesticide-induced resurgence of pest populations. To deter planthopper outbreaks, a more ecologically sound management strategy is being implemented, one based on a thorough investigation of population dynamics, natural enemies, and the genetics of host plant and insecticide adaptation. In the natural habitats of North America and Europe, scientists have also used planthoppers as model organisms to test ecological and evolutionary theory. The consequence of these diverse studies is an extremely scattered literature on planthoppers that has never been synthesized from an ecological perspective. This volume summarizes what is known about planthopper ecology and biological control. It takes a theoretical approach yet is deeply concerned with the application of theory to the practical problems of pest management.

Download or read book Egg Parasitoids in Agroecosystems with Emphasis on Trichogramma written by Fernando L. Consoli and published by Springer Science & Business Media. This book was released on 2010-09-28 with total page 481 pages. Available in PDF, EPUB and Kindle. Book excerpt: Egg Parasitoids in Agroecosystems with emphasis on Trichogramma was conceived to help in the promotion of biological control through egg parasitoids by providing both basic and applied information. The book has a series of chapters dedicated to the understanding of egg parasitoid taxonomy, development, nutrition and reproduction, host recognition and utilization, and their distribution and host associations. There are also several chapters focusing on the mass production and commercialization of egg parasitoids for biological control, addressing important issues such as parasitoid quality control, the risk assessment of egg parasitoids to non-target species, the use of egg parasitoids in integrated pest management programs and the impact of GMO on these natural enemies. Chapters provide an in depth analysis of the literature available, are richly illustrated, and propose future trends.

Download or read book Indian Insects written by S Ramani and published by CRC Press. This book was released on 2019-10-16 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects are the most interesting and diverse group of organisms on earth, many of which are useful as pollinators of crops and wild plants while others are useful as natural enemies keeping pestiferous insects in check. It is important to conserve these insects for our survival and for this the diversity of insect species inhabiting the different ecosystems of our country must be known. The cornerstone to studies of any kind of organismal diversity is their taxonomic identity. Even after over two and half centuries of studies, so little is known of the insect wealth of our country. It has contributions from taxonomists who have been studying Indian insects for long, this book offers up to date information on many important groups of Indian insects seeking to fill the lacuna of a long felt need for a comprehensive work on the taxonomy of Indian insects. Salient features: Provides an up-to-date taxonomy of major insect groups of India Presents identification keys with illustrations of several important groups of Indian insects Gives a new insight into why insects are so abundant Addresses fundamental questions in mechanoreception and cross kingdom interactions using insects as model systems Indian Insects: Diversity and Science is a festschrift to Professor C. A. Viraktamath, an insect taxonomist par excellence. It has been designed to cater to the needs of academicians, researchers and students who wish to identify insects collected from local environments and will be an invaluable aid for those working in the areas of systematics, ecology, behaviour, diversity and the conservation of insects.

Available in PDF, EPUB and Kindle. Book excerpt: The New World Mymaridae include 59 genera and subgenera of which 9 are described as new. In addition, 19 species are described. Seven species-groups of Gonatocerus Nees are recognized and four species-groups of Acmopolynema are also proposed. Keys to females and males of the New World genera are provided and keys to subgenera are included under the respective genera. For each genus a diagnosis, synonymy, distribution, and list of known species for the New World are given. Nine described genera and six nominal genera are recorded from the New World for the first time. The book is illustrated with 191 photos and drawings.
