Download or read book Insect Enemies of Eastern Forests Classic Reprint written by Frank Cooper Craighead and published by Forgotten Books. This book was released on 2018-09-23 with total page 690 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Insect Enemies of Eastern Forests In the publication on the western insects, emphasis is placed on bark beetle control, for in the western forests there still remain great reserves of overmature timber, which are subject to enormous bark beetle losses. Naturally, bark beetles and measures for suppressing their outbreaks are of overshadowing importance in those areas. In the eastern part of the United States, where there are practically no reserves of mature timber, the forester has before him the matter of growing new forests. Here, the forest-insect problem is principally the prevention of outbreaks. Therefore in this volume considerable emphasis is placed on the possibilities of so adjusting silvicultural practices as to avoid losses, as well as on direct control. Also, in the eastern forests there exists a preponderance of deciduous or hard wood species, which are more subject to attack by insects during log ging and manufacturing operations, and even after being placed in use, than are the conifers. The protection of logs, lumber, and crude and finished forest products is consequently a more important. Phase of forest entomology in the East.

As soon as the buds of the trees begin to swell in the spring, the beetles issue from their winter quarters and mate, and as soon as the buds burst they begin to feed upon the leaflets.

There Seems to be no evidence that the actual number of grapefruit on the unsprayed trees was less than, on the sprayed trees.

Download or read book Collected Leaflets on Insect Pests of Fruit Trees Classic Reprint written by Great Britain Ministry of Agr Fisheries and published by . This book was released on 2015-07-03 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Collected Leaflets on Insect Pests of Fruit Trees The sections in a leaflet follow on naturally. The first thing which attracts attention to a pest is the damage. Under "Plants Attacked and Nature of Damage" is given a list of the crops likely to be attacked and the characteristic signs of injury. Under the next section, "Description and Life-History" are described, the appearance of the pest in its various forms, and its life-history or habits, showing where it lives at each season of the year and which are its vulnerable stages. With this information it is then possible to follow the suggestions given under "Measures of Control," carrying out each operation with discretion and not by rule of thumb - a most important point, for success is often dependent on adapting a measure to meet special local conditions. Notes on Insects in General. - As it is impossible to deal separately with many insects in the leaflets themselves, a few general notes may be found useful. Description. - Insects belong to a group of creatures characterised (1) by the possession of a jointed body which is supported not by bones inside but by a hard horny skin, and (2) by the possession on one or more segments of the body of jointed "appendages" which may be modified to act as legs, jaws, antennae (feelers), &c. Strictly speaking, the term Insects should be confined to the creatures in the group with only three pairs of legs (in addition to other characteristics), such, for instance, as moths, beetles or bugs, but for practical purposes the name usually includes the groups containing mites (red spiders) and spiders with four pairs of legs, and the millipedes and centipedes with many pairs of legs. From the practical point of view no detailed knowledge of the various organs of the body is necessary but it is helpful to know a little of the features which characterise an insect as a living creature. The body consists of three parts - the head, the thorax and the abdomen. (a) The head bears the antennae (or "feelers"). which are not only organs of touch but are probably connected with other senses, possibly in some forms with smell. (Little, however, is known about the senses of insects except that by some means they smell and probably hear also.) There are also on the head the eyes which when well developed enable them to see the shape of things, or in other cases may be only sufficient to detect light or darkness. The mouth, on the underside of the head, is surrounded by "appendages" which vary in the different groups, in some taking the form of biting jaws and fingerlike organs to push food between them, while in others the same organs may be modified so as to form a "trunk" enabling the insect to bore holes and suck up juices.

Download or read book Control of Pests and Weeds by Natural Enemies written by Roy van Driesche and published by John Wiley & Sons. This book was released on 2009-01-26 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological control – utilizing a population of natural enemies to seasonally or permanently suppress pests – is not a new concept. The cottony cushion scale, which nearly destroyed the citrus industry of California, was controlled by an introduced predatory insect in the 1880s. Accelerated invasions by insects and spread of weedy non-native plants in the last century have increased the need for the use of biological control. Use of carefully chosen natural enemies has become a major tool for the protection of natural ecosystems, biodiversity and agricultural and urban environments. This book offers a multifaceted yet integrated discussion on two major applications of biological control: permanent control of invasive insects and plants at the landscape level and temporary suppression of both native and exotic pests in farms, tree plantations, and greenhouses. Written by leading international experts in the field, the text discusses control of invasive species and the role of natural enemies in pest management. This book is essential reading for courses on Invasive Species, Pest Management, and Crop Protection. It is an invaluable reference book for biocontrol professionals, restorationists, agriculturalists, and wildlife biologists.
