Book Description
Fourteen informative papers dealing with their DNA, species interactions, adventiveness, host specificity, potential as boi-contol agents of weeds, chemical control, behaviour, their role in fungal pathogen epidemiology, influence in forests and on ornamentals, collecting and mounting techniques and their interaction with crops are presented here. This is an extensive and valuable contribution to eriophyoid science and a must for present and future researchers in this field.

Book Description
Ever since its original publication in Germany in 1938, Max Schweidler's Die Instandetzung von Kupferstichen, Zeichnungen, Buchern usw has been recognized as a seminal modern text on the conservation and restoration of works on paper. To address what he saw as a woeful dearth of relevant literature and in order to assist those who have 'set themselves the goal of preserving cultural treasures, ' the noted German restorer composed a thorough technical manual covering a wide range of specific techniques, including detailed instructions on how to execute structural repairs and alterations that, if skilfully done, can be virtually undetectable. By the mid-twentieth century, curators and conservators of graphic arts, discovering a nearly invisible repair in an old master print or drawing, might comment that the object had been 'Schweidlerized.' This volume, based on the authoritative revised German edition of 1949, makes Schweidler's work available in English for the first time, in a meticulously edited and annotated critical edition. The editor's introduction places the work in its historical context and probes the philosophical issues the book raises, while some two hundred annotati

Book Description
An enthusiastic, witty, and informative introduction to the world of insects and why we—and the planet we inhabit—could not survive without them. Insects comprise roughly half of the animal kingdom. They live everywhere—deep inside caves, 18,000 feet high in the Himalayas, inside computers, in Yellowstone’s hot springs, and in the ears and nostrils of much larger creatures. There are insects that have ears on their knees, eyes on their penises, and tongues under their feet. Most of us think life would be better without bugs. In fact, life would be impossible without them. Most of us know that we would not have honey without honeybees, but without the pinhead-sized chocolate midge, cocoa flowers would not pollinate. No cocoa, no chocolate. The ink that was used to write the Declaration of Independence was derived from galls on oak trees, which are induced by a small wasp. The fruit fly was essential to medical and biological research experiments that resulted in six Nobel prizes. Blowfly larva can clean difficult wounds; flour beetle larva can digest plastic; several species of insects have been essential to the development of antibiotics. Insects turn dead plants and animals into soil. They pollinate flowers, including crops that we depend on. They provide food for other animals, such as birds and bats. They control organisms that are harmful to humans. Life as we know it depends on these small creatures. With ecologist Anne Sverdrup-Thygeson as our capable, entertaining guide into the insect world, we’ll learn that there is more variety among insects than we can even imagine and the more you learn about insects, the more fascinating they become. Buzz, Sting, Bite is an essential introduction to the little creatures that make the world go round.
