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.

Book excerpt: Excerpt from Collected Leaflets on Fungus Pests and Allied Diseases of Fruit Trees Unlike insect pests, which are for the most part more or less clearly understood, there is often a certain mystery in the public mind connected with fungi. Their strange form, sudden appear ance and devastating habits are not readily explainable. To the practical fruit grower painful familiarity with their presence soon robs fungus parasites of any mysterious charm, and, by force of circumstances, he is compelled to study them, if it be only their mode of attacking plants and the best methods of keeping them at bay. Whether, however, the origin and} habits are understood or not, it may not be inadvisable to point out at the commencement of this volume the main outlines of the life of any ordinary fungus.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Insects Attacking Fruit Trees Another great class of insects, such as grasshoppers, tree-hoppers, leaf-hoppers and plant bugs, have only three main stages, namely, adult, egg and larva. As a rule the larvae of these insects are called nymphs. There is no pupal stage. The nymphs usually resemble closely the adults but never have fully developed wings, though the older ones have wing pads, which in the adults have developed into wings. Nymphs, like ordinary larvae, moult from time to time, and at the last moulting become adults. Such insects are said to have incomplete metamorphosis.

This book was released on 2018-02-08 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Insects Destructive to Fruits Insects are among the most formidable enemies to success ful fruit-culture. The losses occasioned by the plum curculio alone amount to more than a million of dollars annually. Orchardists are sometimes deterred, by the attacks of this in sect, from attempts to raise the apricot, nectarine, peach, and plum; and the market supply of apples and pears is often much disfigured by it. The apple-worm, or codling-moth, is even a more formidable insect pest. New York fruit-growers alone yearly furnish $2, worth of apples and worth of pears to feed this insect; and other similar apple-growing States report nearly as large an annual loss from its ravages. The depredations of many other insect pests, like the apple tree and the peach-tree borers, the canker-worms, the tent caterpillars, the apple maggot, and the pear psylla, each causes annual losses amounting to several hundred thousand dollars. As a general rule those remedial measures are of little value, which attempt merely to repel insects without destroy ing them. Experiments show that rarely is an insect repelled from attacking any part of a plant by the application of odor ous substances, like carbolic acid, tar, etc. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Insects Injurious to Fruits It has been the aim of the author of this work to bring together all the important facts relating to insects known to be injurious to fruits in all parts of Canada and the United States, to add to the information thus obtained the knowl edge he has acquired of the habits and life-history of many of our insect pests by an experience of over twenty years as a fruit-grower and a student of entomology, and to pre sent the results in as concise and plain a manner as possible, avoiding all scientific phraseology except such as is necessary to accuracy. The arrangement adopted under the several headings, by which the insect pests which attack the different parts of the tree or vine under consideration are grouped together, will, it is hoped, with the aid of the illustrations, greatly facilitate the determination of any injurious species. When having before him its history briefly traced and the remedies which have been found most useful in subduing the insect, the reader will at once be enabled to decide as to the best meth ods to be employed. The author desires to make the fullest acknowledgment to those of whose work he has availed himself.
