Book excerpt: Excerpt from Lectures on Entomology The numerous beings comprehended under the name of insects, offer to our regard so many interesting objects of contemplation and research, that their history has deservedly assumed a prominent place among the natural sciences; although not to be compared with many other animals in direct utility to man, they are by no means destitute even of the interest produced by that consideration, while they possess advantages as a subject of study and investigation equal to any other branch of zoology. Such is the extent of the subject and the variety of aspects in which it may be viewed, that minds of very different tastes and capacities may find congenial occupation in some one or other of its numerous details; even to the fine assortment of its colours, every thing seems on purpose to please the eye of man; each tribe of this extensive class of animals possesses peculiar attributes deserving of our regard. The extreme beauty of the (Lepidoptera) or Butterflies, the striking contrast they present in the dilferent stages of their existence so remarkable, as to have -caused them to be regarded by a mystical philosophy, as the types of the luman soul released from its material incumbrance; their habits and times of appearance, the one suggesting the purity of an ethereal nature, the other associating them in the mind of the observer, with the beauty of external nature, and the genial influence of the seasons, have alike contributed to render them objects of general favour. Linnæus has divided insects into seven orders: 1st. - the Coleoptera they are such as have crustaceous shells, which shut together and form a longitudinal suture down the back of the insect, as the Stag Beetle. 2nd. - Hemiptera have their upper wings, usually half crustaceous and half membraneous, not divided by a longitudinal suture, but incumbent on each other, as the (Cimex) or Field Btig. 3rd. - Lepidoptera are insects having four wings covered with fine scales, in the form of powder, as in the Butterfly. 4th. - Neuroptera have four membraneous transparent naked wings, generally like net-work, as the Dragon Fly. 5th. - Hymenop-Tera are insects with four membraneous wings, tail furnished with a sting, as in the Bee. 6th. - Diptera are such as have only two wings and poisers, as the Fly. 7th. - Aptera having no wings. This last division contains Scorpions, Spiders, &c. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

This book was released on 2015-07-21 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Insects of Economic Importance Outlines of Lectures in Economic Entomology Not all insects of economic importance are included in these outlines. To discuss them all, a book of many times the size of this would be needed. However, the principal pests of our main fruits, vegetables, cereals, farm animals, shade-trees, and of the household are discussed. A brief summary of the life habits of each, so far as they are known, is made, and the latest methods of control are outlined. In addition, a concise discussion of insecticides is given together with formulae and directions for making and applying them. Finally, references are given to the more important sources of information regarding the insects and their control. As far as possible, references are made to bulletins available to the general student and to those publications giving good illustrations of the insects, together with the most approved methods of control. It is neither possible nor desirable to give references to all the literature on any one insect pest but additional references to the later literature as it appears from time to time will be cited during the course.

Download or read book Sanitary Entomology written by W. Dwight Pierce and published by Forgotten Books. This book was released on 2015-06-27 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Sanitary Entomology: The Entomology of Disease, Hygiene and Sanitation In May, 1918, a class was formed among the entomologists of the country to study the recent developments in the entomology of disease, hygiene, and sanitation, for the purpose of equipping themselves for any special service which they might be called upon to render during the war. The lectures were mimeographed week by week and mailed to the enrolled membership, which numbered in excess of 500. The war emergency is over and the mimeographed lectures have practically all been distributed. These lectures, however, dealt as much with domestic as with military problems, and they have now been completely revised up to date of March 1, 1919, and are given forth as a series of lectures dealing with the entomological problems of peace times from the standpoint primarily of municipal, industrial, and household problems, and also with the hope that the course will be of assistance to teachers, and will stimulate research among investigators. Many important topics have been omitted, for we cannot hope to present the whole subject in a book of this size. This phase of entomology is one which is destined to become very important as our knowledge of disease transmission increases. There are many unworked and insufficiently worked problems now in sight, and these lectures will be found to suggest numerous possible lines of research. I wish at this time to express my appreciation of the services of Mr. Jacob Kotinsky, who served as Secretary of the Class, and of my collaborators in this course of lectures. As nearly as possible the International Rules of Nomenclature are followed, but in Entomology the practice had not been followed of enclosing the original author's name in parenthesis followed by the name of the author responsible for the present combination, and it has been impossible in the present volume to obtain all of the necessary information.
