Book excerpt: Excerpt from Insects Injurious to the Household and Annoying to Man Some one has remarked in a rather facetious vein that, from a zoological standpoint, the present age may be called the age of insects. On second thought, the remark holds more reason than might appear at first sight. We are especially impressed with the importance of the relation to man of these tiny, but multitudinous, forms of life when we recall that the species of insects outnumber the species of all other animals combined; that the insect pests in this country alone cause a loss of over a billion dollars annually; that several hundred trained men in the United States are giving their entire time to a study of these pests; and that thousands of letters are sent each year to our government agencies, requesting information regarding insects and means of fighting them. Until within the last few years the economic importance of insects has been attributed to their indirect injuries to man through attacks on the things that he produces. Suddenly, almost within the last decade, insects have assumed an entirely new and exceedingly important significance through knowledge of their direct injuries to man himself. Since the epoch-making discoveries were made that mosquitoes carry malaria and yellow fever, insects, especially those frequenting the household, have assumed a most unexpected importance. The hum of the mosquito and the buzz of the house-fly have become fraught with an entirely new significance.

Book excerpt: Excerpt from A Treatise on Some of the Insects Injurious to Vegetation The word Insect, which, in the Latin language, from whence it was derived, means cut into or notched, was designed to express one of the chief characters of this group of animals, whose body is marked by several cross-lines or incisions. The parts between these cross-lines are called segments, or rings, and consist of a number of jointed pieces, more or less movable on each other. Insects have a very small brain, and, instead of a spinal marrow, a kind of knotted cord, extending from the brain to the hinder extremity; and numerous small whitish threads, which are the nerves, spread from the brain and knots, in various directions. Two long air-pipes, within their bodies, together with an immense number of smaller pipes, supply the want of lungs, and carry the air to every part. Insects do not breathe through their mouths, but through little holes, called spiracles, generally nine in number, along each side of the body. Some, however, have the breathing-holes placed in the hinder extremity, and a few young water-insects breathe by means of gills. The heart is a long tube, lying under the skin of the back, having little holes on each Side for the admission of the juices Of the body, which are prevented from escaping again by valves or clappers, formed to close the holes within. Moreover, this tubular heart is divided into several chambers, by transverse partitions, in each of which there is a hole shut by a valve, which allows the blood to flow only from the hinder to the fore part of the heart, and prevents it from passing in the contrary direction. The blood, which is a colorless or yel lowish fluid, does not circulate in proper arteries and veins; but is driven from the fore part of the heart into the head, and thence escapes into the body, where it is mingled with the nutritive juices that filter through the Sides Of the intestines, and the mingled fluid penetrates the crevices among the flesh and other internal parts, flowing along the Sides Of the air pipes, whereby it receives from the air that influence which renders it fitted to nourish the frame and maintain life.

This book was released on 2017-12-05 with total page 514 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Insects Injurious to the Household and Annoying to Man The present work is not intended as a treatise on the relation of insects to disease. The author's colleagues are now at work on a thorough and extended discussion of that phase of the subject. In the following pages, the writer devotes the principal part of the discussion to the habits, injuries, and control of insects simply as pests of the household and of man, contenting himself with a brief summary of the relation of insects to disease. It is hardly to be expected that SO brief a work will include all of the insect pests that may invade the household but an attempt has been made to discuss, at least, the most important ones with which our present knowledge makes us more or less familiar. The erroneous ideas and unnecessary fears prevalent regarding the poisonous nature Of certain insects and their near relatives and the interest evinced in this matter have seemed to warrant the addition of a chapter on this subject. In this discussion, the author has at tempted to state the Simple truth and to clear away, as far as existing knowledge makes it possible, the hazy and almost superstitious notions regarding the venomous qualities of these small animals.
