A richly illustrated guide to the astonishing variety of beetles around the world Beetles make up about a quarter of known animal species and are arguably the most diverse group of organisms on Earth: almost 400,000 species have been formally described so far, and it is likely that this number merely scratches the surface. In Beetles of the World, Maxwell Barclay and Patrice Bouchard—two of the world’s foremost beetle experts—celebrate these remarkable creatures in all their variety, from their size and appearance to their ecological importance. Providing concise accounts of all the major families and subfamilies of Coleoptera, Beetles of the World explores beetle anatomy, life cycle, fossil history, feeding habits, role in the food web, habitats, relationship with humans, and classification—as well as the essential part that beetles play in the global ecosystem, and the ways humans can help protect them. Features 300 stunning color photographs Presents family profiles with a distribution map, table of information, and commentary Includes a comprehensive introduction that provides insight into the astonishing diversity of beetles and their histories

Integrated Management of Insect Pests on Canola and Other Brassica Oilseed Crops available in PDF, EPUB and Kindle. This book comprehensively reviews current pest management practices and explores novel integrated pest management strategies in Brassica oilseed crops. It is essential reading for pest management practitioners and researchers working on pest management in canola and other Brassica crops worldwide. Canola, mustard, camelina and crambe are the most important oilseed crops in the world. Canola is the second largest oilseed crop in the world providing 13% of the world's supply. Seeds of these species commonly contain 40% or more oil and produce meals with 35 to 40% protein. However, its production has declined significantly in recent years due to insect pest problems. The canola pest complexes are responsible for high insecticide applications on canola. Many growers rely on calendar-based spraying schedules for insecticide applications. The diamondback moth Plutella xylostella and flea beetles Phyllotreta spp. (P. cruciferae and P. striolata)cause serious damage to canola. In the Northern Great Plains, USA, for instance, P. xylostella is now recorded everywhere that canola is grown. Severe damage to canola plants can be caused by overwintering populations of flea beetles feeding on newly emerged seedlings. Cabbage seed pod weevil (Ceutorhynchus obstrictus), swede midge (Contarinia nasturtii), and tarnished plant bug (Lygus lineolaris) are also severe pests on canola. Minor pests include aphids (cabbage aphid, Brevicoryne brassicae and turnip aphid, Hyadaphis erysimi) and grasshopper, Melanoplus sanguinipes.

Field Guide to Beetles of California available in PDF, EPUB and Kindle. With perhaps 8,000 different species, beetles are easily the largest group of animals in California and can be found virtually everywhere in the state. They grapple over flower heads, lurk in pantries, paddle through pristine mountain streams, amble over dunes, and buzz about porch lights on warm evenings. But until now, there was no single resource for identifying the most commonly encountered beetles in California’s mountains, valleys, and deserts. This valuable field guide, a companion volume to Introduction to California Beetles published in 2004, identifies more than 500 of the state’s more conspicuous and colorful species, with the majority presented in stunning color photographs. Written and designed for amateur naturalists, students, and field biologists, it is chock-full of what every beetle watcher wants to know, including suggestions for finding beetles, starting a beetle collection, and keeping beetles in captivity. The informative, accessibly written species accounts include information on beetle identification, natural history, and distribution. * Features 300 color photographs, 110 drawings, and 2 maps * Covers 569 species in 56 families * Lists California’s sensitive, threatened, and endangered species * Provides resources and web sites for further study of California beetles
