This book was released on 2013-06-29 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects multiply. Destruction reigns. There is dismay, followed by outcry, and demands to Authority. Authority remembers its experts or appoints some: they ought to know. The experts advise a Cure. The Cure can be almost anything: holy water from Mecca, a Government Commis sion, a culture of bacteria, poison, prayers denunciatory or tactful, a new god, a trap, a Pied Piper. The Cures have only one thing in common: with a little patience they always work. They have never been known entirely to fail. Likewise they have never been known to prevent the next outbreak. For the cycle of abundance and scarcity has a rhythm of its own, and the Cures are applied just when the plague of insects is going to abate through its own loss of momentum. -Abridged, with insects in place of voles, from C. Elton, 1924, Voles, Mice and Lemmings, with permission of Oxford University Press This book is an enquiry into the "natural rhythms" of insect abundance in forested ecosystems and into the forces that give rise to these rhythms. Forests form unique environ ments for such studies because one can find them growing under relatively natural (pri meval) conditions as well as under the domination of human actions. Also, the slow growth and turnover rates of forested ecosystems enable us to investigate insect popula tion dynamics in a plant environment that remains relatively constant or changes only slowly, this in contrast to agricultural systems, where change is often drastic and frequent.

Available in PDF, EPUB and Kindle. Book excerpt: This text considers forest insects occurring in forest ecosystems, specialized forestry settings, and urban forests, with an approach and coverage that make it suitable for use in both undergraduate and graduate courses in forest entomology and forest protection. Early chapters introduce entomology, middle chapters provide the first comprehensive treatment of the principles of Integrated Pest Management (IPM) of forest insects, and later chapters discuss the pest insects according to their feeding group.
