Book excerpt: Southeast Alaska's remaining virgin forests have few insect pests. The black-headed budworm and the hemlock sawfly, both western hemlock defoliators, are the most important species. They kill some trees, kill tops in others, and cause growth loss, but stands survive their attacks. Extensive conversion of virgin stands to second growth may result in an increase in pest problems as it has in similar areas such as coastal British Columbia. ‍?‍?Widespread use of insecticides to control major outbreaks is not practical because of risk of contaminating salmon-spawning and trout-rearing streams; but insecticide use may be justified in local, high value areas. Weather, diseases, and parasites control outbreaks naturally. Damage-prone stands should be identified and harvested before insect attack or salvage-logged following outbreaks. Ideally, second-growth stands should be managed for resistance to insect pests.

Available in PDF, EPUB and Kindle. Book excerpt: A completely updated and translated edition of the author's famous book Atlas zur Biologie der Wasserinsekten. br/> This comprehensive work gives a vivid overview of the numerous adaptations of aquatic insects to life in an aquatic environment. 148 picture plates show more than 900 scanning electron microscope photographs with magnifications from 2.5 to 12,000 times natural size. Besides the habitus, they depict the wealth of morphological structures on the body surfaces. Explanatory texts as well as more than 150 additional line drawings, graphs and diagrams accompany each picture plate on its opposite page. In order to create an overview, on which the readers can orient themselves, a broad spectrum of all insect orders that include aquatic and semiaquatic insects has been chosen: Collembola, Ephemeroptera, Odonata, Plecoptera, Heteroptera (Nepomorpha, Gerromorpha), Megaloptera, Planipennia, Coleoptera, Hymenoptera, Trichoptera, Lepidoptera, Diptera (Tipulidae, Limoniidae, Blephariceridae, Deuterophlebiidae, Psychodidae, Ptychopteridae, Dixidae, Chaoboridae, Culicidae, Simuliidae, Chironomidae, Ceratopogonidae, Stratiomyidae, Athericidae, Tabanidae, Syrphidae, Ephydridae, Muscidae). The book includes aquatic insects from all continents and from a wide variety of aquatic habitats. The Biological Atlas of Aquatic Insects was inspired by the fascinating variety of aquatic insects and their diverse adaptations to a life in the aquatic environment. Underlying the diversity of life histories and differing life forms (burrowers, climbers, sprawlers, clingers, and swimmers) and the adaptations of mouthparts and feeding behaviour to the trophic systems (shredders, collectors, scrapers, piercers, predators, and parasites) are the necessary physiological mechanisms that make it possible for the insects to ecologically adapt to an aquatic mode of life. The central themes of the book, the basic functions of an aquatic mode of life, respiration and osmoregulation, have been described for all of the insect groups. Without these basic functions life in fresh water would not be possible. They are important physiological components and play a significant role in answering the question: What makes originally land dwelling insects turn into aquatic insects? The Biological Atlas of Aquatic Insects is intended for both professional and amateur entomologists working with aquatic insects as well as for students of biology and limnology and should reveal to them the fully adapted aquatic insects, which participate in freshwater ecosystems. The Biological Atlas of Aquatic Insects has already had some fine reviews in entomological journals.

Larson and published by NRC Research Press. This book was released on 2000 with total page 997 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book first reviews the biology of Dytiscidae or water beetles, including life history and ecology. It then defines and keys adults & larvae (when known) of dytiscid fauna of Canada, the United States, and for some taxa also northern Mexico. The focus is on the fauna of Canada & Alaska, and adults of the 276 species known from this region are treated in detail. For each Canadian-Alaskan species, the following information is presented: nomenclature & synonymy; selected references; description, including illustrations of taxonomically important characteristics; comments on classification or variation; notes on ecology; and description of the species range, accompanied by a map of collection records. Checklists of the dytiscid fauna of Canada/Alaska are also presented, with the distribution of the species recorded by province/territory and Canadian ecozone. Includes systematic index.

Book excerpt: This is the first exhaustive review of literature on marine insects, which are defined in this volume as those that spend at least part of their life in association with the marine environment. Not only are true insects, such as the Collembola and insect parasites of marine birds and mammals, considered, but also other kinds of intertidal air-breathing arthropods, notably spiders, scorpions, mites, centipedes and millipedes, which live and feed with, or even on, the insects of marine habitats. The chapters, written by leading authorities, are divided into two sections, the first treating primarily ecological aspects, the second dealing with major groups of insects in marine environments.

Book excerpt: This book of spectacular full-color photographs of common eastern aquatic insects is a fly tyer's dream. For centuries anglers have struggled with their peculiar dependency on the aquatic insects that put the word "fly" in fly fishing, discoursing obsessively on how to replicate them with fur and feathers, and even about what to call them. Volumes have been written on the subject, but until now there has never been a book like Fishbugs. Following the success of his first book, hailed as "the most useful book for eastern fly fishers since Art Flick's Streamside Guide," author Thomas Ames Jr. lets his photographic skills take center stage. His bigger-than-life studies of mayflies, caddisflies, and other waterborne insects, captured in extraordinary detail, allow you see them as never before. Fly tyers will appreciate them as models for their imitations, while naturalists and other lovers of nature photography admire them for their intrinsic beauty. His thoughtful prose examines the special characteristics that keep these fascinating insects at the heart of the angler's gentle art and underscores their value as indicators of the health of our inland waters.
