Ornamental trees, shrubs and flowers have always been extremely popular and in large demand. Whether in gardens or parks, common usage of alpines, bedding plants, cacti, cut flowers, house plants and pot plants, as well as herbaceous plants, ornamental grasses, shrubs and trees makes a definitive volume on their pests of essential value to entomologists and plant scientists. The fully revised and updated second edition of Pests of Ornamental Trees, Shrubs and Flowers follows up the successful previous edition with coverage of many new pests and highly detailed color photographs. The book opens with a review of the main features of insects, mites and other major pest groups. . Each major order and family of pests is considered in turn, with details of their status, host range, world distribution, diagnostic features and biology. Descriptions of the characteristic damage caused are also given.
Armored scale insects are among the most damaging and least understood of the pests that prey on forest trees, fruit and nut crops, landscape ornamentals, and greenhouse plants. The passage of U.S. plant quarantine laws was prompted by devastation caused by an armored scale in the nineteenth century, and the appearance of new invasive species remains a vital concern at ports of entry and for arborists, farmers, nursery workers, foresters, and gardeners everywhere. This book provides the most comprehensive available information on the identification, field appearance, life history, and economic importance of the 110 economically important armored scale insects that are found in the United States. The authors have devised the first field key to economic armored scales, which will be invaluable to those trying to identify the pests and prevent the introduction of new exotics. (Most of the species covered are not native to the United States but broadly distributed across the globe.) The extensive color plates and highly detailed line drawings surpass anything available in other volumes on armored scale insects, and have not previously been published. Especially noteworthy are the data on distribution, host plants, and the kinds of damage caused by armored scales. The species descriptions include scientific names, synonyms, common names, field characteristics, microscopic characters, affinities, host plants, distribution by state, life history, economic damage, and selected references.
This atlas presents anatomical descriptions of the xylem, bark and pith of 264 species belonging to 71 families. It highlights the anatomical diversity of trees, shrubs, dwarf shrubs, woody lianas and several of the prominent perennial herbs from the Eastern Mediterranean region, with a focus on the island of Cyprus. The island's topography and biogeographic history combine to provide a wide range of habitats and diverse flora including widespread, endemic, and ornamental species.
The monograph for each species includes a description of the anatomical structures of the stem and twig xylem and the twig's bark and pith, as well as color micrographs of double-stained sections of each of these plant parts. These entries are accompanied by a photograph and a brief description of the plant including stem wood density, height, habit, flower, leaf and fruit characteristics, and a map showing its geographic and altitudinal distribution in the region. Xylem descriptions follow the IAWA lists of microscopic features for hardwood and softwood identification. For bark and pith descriptions, a new coding system developed by the authors is applied. Lastly, the work offers a key for wood identification that was developed to differentiate between groups of species by using a small number of features that are unambiguous and clearly visible. The atlas will be a valuable guide for botanists, ecologists, foresters, archeologists, horticulturists and paleobotanists.
